Description

[Detailed Description of the Invention] [rI - Field of Application on the Beam] This launch (η1 is [51゛] for a breathing apparatus ij using a bullet t:'j and this valve j.:.).

[Conventional technology]

What about figure 3? , Y: In block r4, which shows the device using the next suction valve and publication υ)Wol-Kin, in Tori, 1゛, 1 inhales the entire 2-body suction valve 2)IH+L/, and (1 ``The discharge to Yamaga 3, body actuation device, 4 is this fluid movement r!
1's drive mechanism, 5 is the suction valve body of suction valve 2, 6 is the discharge valve body of discharge valve 3, both valves 2 and 3 are check valves, and 7 supplies the valve body to suction valve 2. A supply section, 8 a receiving section that receives the fluid discharged from the discharge valve 3, and 9 an IJ'f discharge pipe.

I will explain the action of dQ.

Fluid work! 1IIJiφi1 to drive mechanism i (not shown)
For example, during the suction process, both valves 2 and 3 are connected to the third valve (4) so that the DLC body flows only in one direction, but not in the opposite direction to the notch J. Therefore, when the suction valve 2 is open and the discharge valve 3 is closed, fluid from the supply section 7 is injected into the fluid actuated device 1 through the suction port 7111.

In addition to the above, when the exit process is started, the fluid sucked into the #niji body actuation wave 3 and is discharged to the receiving section 8. This suction process and discharge process are repeated.

Note that in the above description, explanation 1 is based on the case where the fluid is regularly sucked in and discharged by the fluid actuated device 1.
The 1H sequence works similarly if it is performed irregularly or optionally. In addition, in the above, it was assumed that the fluid in the supply section 7 is sucked into the pump operating system 1, and the fluid itself is discharged to the receiving section 8 in the next discharge process, but the fluid inside the supply section 7 is In some cases, the liquid may be discharged into the receiving portion 8 as a fluid treated by a chemical reaction or the like.

Fig. 4 is a block diagram showing a conventional pond device using a suction valve and a discharge valve. It operates in the same way as the device.

[Problem that the invention seeks to solve]

The conventional device shown in FIGS. 3 and 4 has an intake valve and a discharge valve that are opened and closed independently, making the structure of the device complicated and requiring less manufacturing time.
, 111 rice is popular and large, especially for moving equipment, etc.
There was a problem that it required a lot of space.

The present invention has been developed to solve these problems, and is small and compact without the need to separately install an intake valve and an exhaust valve. The two purposes are to create a valve crosspiece (,'!) that can smoothly and reliably perform the two functions.

Also, another version of this invention! j4 is as above, 7) r-j
Further, the purpose is to obtain a breathing device that can be filled in a chain stitch where there is air contaminated with smoke or the like during a disaster.

[Means for solving problems]

In the valve mechanism IJ according to the present invention, a valve body is made by integrating an intake suction valve body (hereinafter referred to as suction valve body) and a discharge valve valve body (hereinafter referred to as dF (hereinafter referred to as HjF integral)), and this valve body is rotatable. The inside of the valve is supported so that it has an automatic and non-return action due to the bending of the valve body.

Also, this rash] is related to another discovery! The suction device 2i utilizes the valve mechanism of the present invention, connects and extends a suction member to a suction/exhaust unit, and has a movably suspended member provided on the suction member.

[Sakukawa] According to the present invention, the suction valve body and the discharge valve body are integrated into one valve body, and this valve body is rotatably supported, so that the suction valve body is The valve is opened and closed by the difference in moment acting on the valve body and the discharge valve body, and fluid suction and discharge are automatically and smoothly performed in a narrow space.

In another aspect of the present invention, the valve mechanism of the present invention is used in the breathing apparatus a, and the suction member is attached to the suction tiI unit, making it easy to open and close the valve by breathing.

〔Example〕

FIG. 1 is a cross-sectional view of a valve mechanism according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line TI-II in FIG. It is something.

Reference numeral 10 indicates this valve element, which has the function of connecting to the bearing 8, which is also called a composite valve element with one or two exhaust valves, in which the intake valve element 11 and the exhaust valve element 12 are made integrally, and 13 indicates the intake valve element 11 and the exhaust valve element 12. The joint part 13 of the body 12 is used as the fulcrum 14 and 17 to form the composite valve body 10.
is rotatably supported by the supporting part 15 (2).16 is supported by the housing.
and the suction valve body 11 (il) instead of the central part of the exhaust valve tt12.
It is mounted so that it is located almost above the suction valve body 11 toward L. The valve body 10 is made of rubber, synthetic rubber, resin, or the like. 1T, for the suction valve body 11: Make it larger than the discharge valve body 12, and calculate the moment around the fulcrum 14 acting on the suction valve body 11 from the Q t't h2 inside the valve, or the discharge valve body 1.
It is made so that it is larger than the moment acting on 2.

When one of the suction valve body 11 and the v-outlet body 12 is in contact with the valve seat and is in the working position +'-j k, the external force is in the non-working position i/i. It's becoming like this.

In addition, 'j'i' is the 171st pipe, and 18 is the outgoing pipe.

The action will be explained in terms of ζ.

For example, inhalation method 1. I'm with you, +'lrf book is also 1
From the inlet pipe 17, the suction 71 passes through the body 11 and is sucked into the fluid operating device in the upward arrow direction shown in FIG.

Next, when the discharge process begins, the discharge valve body 12 is opened and the suction valve body 11 is closed, contrary to the above, and the fluid sucked into the driftwood actuator side is removed from the discharge butoid 12 side; 8 pieces are discharged from delivery 18.

Furthermore, this is the flow 11 in the direction of the downward arrow shown in 1; 4. Therefore, since the moment around the fulcrum 14 acting on the suction valve body 11 is smaller than the moment acting on the discharge valve body 12, the suction valve body 11 is rotated one turn clockwise in Fig. 151. 6 to close the suction valve body 11 and bend the discharge valve body 12.
19 bodies are υt from the exhaust chamber 18 and 0゜ like this :) Both valve bodies 11. Regarding the +41 of the 12, C is 7 words. 8

In the above-described embodiment of the present invention, the suction and exhaust pipes 9 are provided in the i body 16 near the suction valve body 11, but both valve bodies 11 and 12
Depending on the size, shape, distance from the fulcrum, etc., this may not necessarily be the case, but when the fluid is discharged from the suction/exhaust pipe 9, the suction valve body 11 closes and enters the operating position 14. Person'1=L)S,.

In addition, in one or more examples of the above-mentioned invention, 4, both valve bodies 11

Furthermore, the fulcrum 14 of K115j valve body 11.12:l'A)
By configuring the valve body 10 so that the moment of rotation does not vary with respect to the flow rate when no flow occurs, it is possible to improve the degree of rotation of the valve body 105. The valve body is made by integrating the valve body and the discharge valve body, and the valve body is made by integrating the valve body and the discharge valve body.
