In Road vehicles have been pyrotechnically operated airbag systems for decades as usually complicated and not dangerous at rest Constructions or systems used. Main function is the inflation of so-called airbags for impact protection of persons in one Time of less than 40 milliseconds by ignition of a pyrotechnic Propellant. The airbags need absorb an impact of up to 50 km / h, this corresponds to about the fall from the 4th floor of a building. They are both frontal, Side and head protection airbags now available. recently There are airbag systems with a noble gas mixture and a release pressure from about 240 bar.

For cyclists there are now inflatable protective jackets equipped with CO2 pressurized bottles, the with very limited filling volume and long filling times due to small exhaust valve cross-sections only limited possible Provide impact protection, usually only the upper body is protected.

For working at higher altitudes There is no protection system so far, what the consequences of a Crash from a certain height for the affected person mitigates.

3. defects previous versions or problems underlying the invention:

to main claim 1 and subclaims 2 to 9:

by virtue of the big one Compressed air or gas pressures with increasing valve opening or pressure / Zugkolbenquerschnittsflächen occurring high tensile and pressure forces on the valves or push / pull piston itself, it is only possible so far only by small valve cross sections compressed air or gas only under very high pressure Memory pressure for the respective technical application in certain required short Release time units. It was therefore not possible to produce enough large compressed air or gas quantities in a desired very short time unit with reasonable effort in the opening of Valves or actuation release pressure or tension piston.

to subclaims 10, 11 and 12:

As in the previously registered patents and utility models - see Page 14 - describe be for the reasons mentioned above as well as mobile and stationary Airbag systems so far exclusively Gas generators on pyrotechnic basis with complicated ignition technology or used small CO2 bottles, it was not possible to date other way in the required very short time units Compressed air or gas stored under pressure in larger quantities release.

at usual Personal protection systems based on pyrotechnic airbag technology the problem of his big Endangerment by the use of up to 350 ° C hot pyrotechnically generated propellant gas and the complicated safety technology against unintentional triggering of the protection system. Also, the volumes and arrangement options this permanently installed so-called airbag systems only limited.

Although there are already several suggestions in For example, the introduction of protective suits for cyclists in the trade failed so far on an acceptable and in reality really working very fast provision of compressed air or gas stored under pressure for the necessary fast filling of very light , with existing protection (leather) clothing combinable protective cover suits or protective cover systems with large volume and any Endausformung. So far, there are only protective jackets for cyclists with very limited filling volume at long filling times and with limited impact protection in combination with small Druckgasdosen- or bottles, which can protect only the upper body in the rule.

to dependent claim 13:

smoke bulkheads be in rooms or Hallways of buildings or ships usually by the installation of expensive (because of the opening and Closing drives) realized fixed flaps or doors. In rail vehicles or trains with openly connected wagons is a sufficient Rauchabschottung technically not yet possible.

With designed according to the main claim 1 system of the dependent claim 5 is it possible at any position within the room or hallway in buildings or ships or within a train system with open wagons one to realize safe and sufficiently fast effective smoke insulation.

to dependent claims 14 and 15:

barriers in container and piping systems are mainly characterized by mechanical, electromagnetic or hydraulically operated Gate valve or shut-off etc. realized, which only with increased Expense later can be installed in existing systems. The use of a designed according to claim 1 system according to dependent claim 14 or 15 allows an economical solution this problem.

4. The Invention According to Leadership or main claim 1 and dependent claims 2 to 9 and the technical Problems as the basis of this invention:

The pressure accumulator, valve and distributor unit according to claim 1 works according to the following scheme (see drawings / a . c . r . G . H . i . b . d . e . f . q . j using legend 1 on page 14 of the description:
The (storage) container A1, for example, made of light metal alloys or carbon fiber or glass fiber reinforced plastic is equipped with a filling closure I11, a Druckprüf- or vent port I13 and the electromagnetic 1-way exhaust valve I12 (drawing / j ) (see drawing / a ).

In with the connections / adapters J1 provided container A1 is the pressure accumulator, valve and distribution unit B1 with integrated Integrated control system, which after the actuation of the exhaust valve I12 outflowing Compressed air or the outflowing Gas corresponding directs or diverts.

About the Adapter J1, the compressed air or the stored gas its intended use in accordance with the in the dependent claims 2 to 9 or 10 to 17 described applications are supplied.

The exact ignition sequence and pressure curve of the partial pressures p1, p2, p3 and p4 is also in the Drawings/ b . d . e . f and q illustrated by the example of a system with 20 bar storage pressure.

When closed, the main valves D1 arranged symmetrically in pairs because of an effective recoil compensation (drawing / c . r ) pressed by the internal pressure to the opposite outflow openings.
Stage I p2 = p3 = p4 = p5 = 20 bar> p1 = 1 bar
Resulting force due to the pressure p2 on the main valve D1 is smaller than the opposite force due to pressure p3 on the valve face the main valve D1, therefore main valve D1 remains closed

By electronic, sensor, demolition or hand ignition by the user (drawing / j ), the electromagnetic 1-way exhaust valve I12 is opened, it comes in the container B1 to the pressure drop, thereby the check valves / valves C1 (Drawing / c . r ) in the storage or control system B1 and in the control valve piston E1 (with control valve head F1 and valve head gasket G1) (Drawing / c . r ) closed, so that by the pressure on the piston crowns of the control valves E1 this against the spring pressure or tension of possibly required biasing springs X1 (drawing / c . r ).
Stage II p2 = p5> p4 = p3> p1 = 1 bar
Force due to pressure p2 on the main valve D1 is now greater than the opposite force due to pressure p3 to the main valve D1, the main valve D1 is opened by the pressure drop of p3 after opening the control valve E1

As a result, the pressure drops within the range of now closed check valves / valves C1, due to the now occurring pressure difference at the main valves D1 sealed by the sliding seals H1 against the storage / control system they are abruptly opened against each other and the compressed air or the gas now flows recoil-free through the two opposite outflow openings from the storage and Leitsytem B1 through the openings J1 in the container A1 in the leads to the protective jacket suits, protective covers, cushions, etc. whereby these are inflated in a very short time or pressure or tension piston quickly can be moved.
Stage III p2 = p3 = p4 = p5> p1 = 1 bar, then p2 = p3 = p4 = p5 = p1 = 1 bar

The according to main claim 1 and subclaims 2 to 9 defined pressure accumulator, Valve and distribution unit can be 1-axis, 2-, 3- or n-axis System are produced.

At the 1-axis system is each a discharge opening, each with a control valve E1 and in each case a main valve D1 for recoil compensation symmetrically within of the memory B1 or the container A1 opposite.

In the drawings, essentially a 3-axis system is shown by way of example. (see especially drawing / a )

The outflow at the main valve D1 are dimensioned such that an emptying the memory unit A1 / B1 in a maximum of 40 to 50 ms is possible. The 1-axis system required relatively large diameter the outflow opening of 4 cm at z. B. a storage pressure of 20 bar would be in conventional Way of valve opening a lot size Presuppose operating forces, which through the use of conventional electromagnetic valves could not be applied (sieve Example calculation page 8 of the description). It would have the contact pressure as a difference value the pressures overcome p3 and p2 which is just at e.g. a storage pressure of 20 bar a very would require high force.

by virtue of the training of the control system B1 is the main valve at rest D1 pressed with the control valve E1 on the outflow port because of one by the pressures p2 and p3 existing on the different surface portions of the valve surface Differential force. By the at opening the exhaust valve I2 caused pressure drop inside the Systems is due to the now arising pressure imbalance between p2 and p3, the control valve E2 and thereby also the main valve D1 opened almost on its own ("judo principle").

The complete illustration of the compressed air / gas storage, valve and distribution unit according to main claim 1 and subclaims 2 to 9 is in the drawings / a (Front view / cut), c and r (Detail views) G (Section A..A), H (View B) and i (View C), using Leger 1 on page 14 of the description. The design of the unit is here only a suggestion and can be formed according to the respective ergonomic or aerodynamic requirement, etc.

The individual phases of the valve control or the pressure profile in the overall system are shown in the drawings. b . d . e . f - Presentation of the ignition process in 3 stages - or Zeichn./ q - Representation of the pressure curve of the partial pressures p1, p2, p3, p4 and p5-, shown.

"Judo Principle" - see also drawings / b . d . e . f . q - Using the example of a system with a memory pressure of 20 bar described:
In idle state, p1 = 1 bar, p2 = p3 = P4 = p5 = 20 bar (eg).

A small force to operate the exhaust valve I12 leads to a one-sided pressure drop, so that p4 = p3 less than p2 = p5, this causes a sufficiently large force to open the Main valve D1, since p2 now> p3, whereby suddenly the stored compressed air or gas quantity are released can.

After opening all Main valves D1 prevails in the entire system a pressure of> = 1 bar. For example, one Skin-Tightening (System G2 (2)) with about 1 m3 volume when inflated to fill, you have to in the storage, valve and distribution unit according to claim Store 1 approx. 0.050 m3 at 20 bar. Greater pressures are even when using of carbon fiber or glass fiber reinforced plastics as container material hardly possible.

Around in a maximum of 50 milliseconds a protective cover system or an impact pad system according to the subclaims 10, 11 and 12 according to the main claim 1 and subclaims 2 to 9 to fill up, needed at p1 = 20 bar storage pressure, a volumetric flow v point of 0.556 m3 per second.

For compressed air with a density of 23.32 kg / m3 at 293.16 ° K = 20 ° C and a resistance number Xi = 10 of the total system must have the cross-section A of the main valve D1 sealed outflow at a 1-axis system 12.9 cm2, which is a diameter of Dm = 4.05 cm means.

Conceivable is also the use of CO2, CH2, N2, Ar or He as compressed gas. These gases and the compressed air vary in the values of their gas constants.

According to the equation ro (density) = p (pressure) / [Ri (gas constant) × T (temperature)] are included Use of different gases through the different specific ones Dense different discharge velocities w possible. (For details, see example calculation on page 8 of the description).

The principle of the 1-way exhaust valve I12 is shown in Drawing / j shown. The storage system B1 can be filled at any time via the charge valve I11 to the limit pressure, the system is secured during the loading process by a safety and pressure test valve I13.

The Pressure test Relief valve I13 may cause a pressure reduction in the protective sheath systems or impact pad systems after the impact of the to be protected Person used to be similar the pressure relief in conventional airbags.

The filling of the memory B1 via the filling valve I11 with the aid of e.g. a compressor.

Point 4 summarized:

The Compressed air / gas storage, valve and distribution unit according to main claim 1 and dependent claims 2 to 9 can be arranged in pairs (due to recoil compensation) be prepared as 1-, 2-, 3 -... n-axis unit and thus different Container sizes adjusted be different sizes Compressed air or gas quantities in the desired short time unit release. The more axes with corresponding subsystems Unit according to main claim 1 and subclaims 2 to 9, the more they can be smaller respective outflow openings and thus the heights the entire unit fail, the more complex it is also the construction effort.

The Training the container shape according to the respective requirements, on the one hand as a portable unit ergonomics and aerodynamics aspects etc. to carry on the back - on the other hand as firm on one Component mounted unit - like in the conventional Airbag. These according to claim 12 fixed built impact pad Systzeme can like traditional ones Airbags in vehicles as a front, head, side or knee impact cushion accomplished according to their use in road, rail or Aircraft.

The listed above by examples main technical problem is the provision of large quantities pressurized or pressurized gas in very short time units, e.g. to fill of personal protective cover systems (G2 (1) + G2 (2)) of any shape and size when inflated on the body portable or as solid impact cushion systems (G2 (3)) on components fixed to a rail, road or airplane, or for operation of pressure piston with high forces or long piston paths in short time units in devices, tools, Machines or other devices.

The dangerous use of pyrotechnically produced propellant gases in conventional airbag systems due to the high temperatures - up to 350 ° C - should be replaced by the use of suitable compressed air or chemically / physically harmless gas systems, which can be activated in the same short time units as these conventional systems , Separate conventional airbag systems based on gas generators or pyrotechnics eg for safety reasons for use in aircraft.

The Compressed air / gas storage, valve and distribution unit according to main claim 1 and dependent claims 2 to 9 represents a technically feasible solution of the problems mentioned represents.

Example calculation for the sequence of compressed air or gas emptying in the storage, valve and distribution unit A1 / B1 according to main claim 1 on the example of the protective cover suit G2 (2) according to dependent claim 2:

Around at initial pressure pI = 20 bar and a temperature of 20 ° C with a Storage volume V1 = 0.050 m3 the discharge of compressed air in 50 up to 90 milliseconds to fill a protective suit G2 (2) with volume V2 = approx. 1.000 m3 and a final pressure pII = 1 bar to reach is an outflow velocity v point = delta V (= 0.050 m3) / 0.09 msec = 0.556 m3 per second necessary.

This is possible at the initial pressure of 20 bar with compressed air at a density ro = 23.32 kg per m3 and the gas constant Ri = 287 and at a temperature of 20 ° C, where ro is calculated as the quotient of the pressure pI in N / m2 and the product of Ri and T.
(Note: The basis is the general equation of state for gases: p × V = K × m × Ri × T)

Assuming a steady state flow, the cross section of the outflow openings in the storage and distribution system B1 is calculated as follows: A (cm2) = v point (m3 / sec) / square root from the quotient of delta p (N / m2) × 2 and the drag coefficient Xi (= 10) × 2

These outflow of 0.556 m3 per second can therefore with a through the main valve D2 sealed in the storage, valve and distribution unit A1 / B1 Outflow opening with a cross-section A = 9.9756 cm2 (rounded about 10 cm2) reached become.

It was at the discharge resistance Xi assumed a value of 10.0 for security. The smaller Xi is, the smaller the pressure difference delta p can be or the smaller may be the pressure pI.

at a uniaxial arrangement of the storage, valve and distribution system A1 / B1 would be so that a diameter d = 3,564 cm for the two opposite outflow required. Multi-axis systems require correspondingly smaller ones Cross sections of the discharge openings.
