The exemplary embodiment shown in FIG. 1 of an embodiment of a hydraulic device in the form of a motor has a first cylindrical housing TO. The gel housing 10 has, as shown in Pig. 2, an axis 11 ui and an inner wall 12. The inner wall 12 is provided with a plurality of teeth or raised points 13, which are arranged at an appropriate distance from one another in order to form an equal number of low points H. For the sake of simplicity, the raised areas 13 are hereinafter referred to as teeth, and from Pig. 2 it can be seen that these teeth 13 can work together with outer teeth 15 of a rotor 16 in the usual manner. .

The rotor 16 has one tooth 15 less than teeth 13 are provided on the inner wall 12 of the housing 1o. In the example shown, the rotor 16 has six teeth 15, while the one formed by the housing To Stator has seven teeth 13. The axis 17 of the rotor 16 is offset with respect to the axis 11 of the housing 1o, see above that the movement performed by the rotor 16 is hypocycloidal i.e. a rotary component and a trajectory component Has.

The second Housing 18, like the first housing 10, is cylindrical and, as can be seen from FIG. 3, has a axially extending chamber 2o provided, which has an axis 21 which is coaxial with the .. chee'i of the first housing Io lies. Pressure medium is fed into the can 2o through a calibration. radially extending Durohfluß orifice 22 let in and out of the second housing 18 through, one generally axially extending throughflow opening or an outlet 23 is omitted therethrough.

The pressure medium entering through the inlet opening 22 passes through. Passages 25 through into the Stator chamber 24 (FIG. 2), pressure medium emerging from stator chamber 24 passes through, further passages 26 through to the outlet opening 23. Accordingly, in the illustrated embodiment, at any given moment a passage 27 (FIG. 3) is present, which guides pressure medium neither into nor out of the stator anchors 24.

The "switching" or reversal of the passages 25 to 27 is carried out by a reversing element 28 (commutator), which is shown in FIGS. 1, 3 and 4. To enclose the reversing element 28, an end plate 29 can be used.

The reversing member 28 has a generally cylindrical shape and its axis coincides with the axis 21 and is coaxial with the axis 11. The reversing element 28 is provided with a generally axially extending bore 3o which, as can be seen from FIG 3, the passages 25 are exposed. Thus, in the state shown, pressure medium enters the passages 25a shown in FIG This causes the rotor 16 to rotate in the direction indicated by the arrow in FIG. 2, which results in a change in the operating characteristics of the various openings 25a, 26a, 27a. Accordingly, at any given point in time there is a plurality of openings 26a (less than the total number of passages 25 to 27) communicating with the outlet opening, as well as a similar plurality of openings 25a, mutually exclusive of the first-mentioned plurality of openings 26a, present, which are in communication with the inlet port 22 "

The uni control member 28 is advantageously rotatably mounted in the chamber 2o by means of needle roller bearing 32, and

the passages 25 to 27 are arranged such that they with the chamber 2o at a distance inward from the the Kramer 2o surrounding wall 2oa in connection stand. In the illustrated embodiment, this is achieved in that the passages 25 to 27, as best from Pig. 1 can be seen, are arranged axially obliquely inward.

The rotation of the Uus expensive organ 20 is made by a pin or bolt-like reinforcing or enlarging member 33 obtained which extends into a part 3oa of the bore 3o which is eccentric to the axis 21. The enlarging member 33 has a central part that is provided with wedges 34, which with wedges 35 an in the rotor 16 provided bore 35 cooperate, which is concentric to the axis 17 of the rotor 16. This means that when the eotor 16 is in the stator chamber 24 follows its hypocycloid-like path, the enlargement member 33 the rotational component of the hypocycloid-like Movement does not follow, but its path component ▼ is strengthened or enlarged by the reversing device 28 to drive.

According to Pig. 1 line end of the housing is 1o a third housing 37 attached. The third housing has an axis 33 which is coaxial with axes 11 and 21 runs, and it forms a chamber 39 »in which an annular widened or enlarged part 40 a

The ring-shaped enlarged part 40 has an axial bore 42 which is provided with wedges 43 which cooperate with wedges 44 which are provided at that end of the enlarging member 33 which is opposite the end received in the reversing member. The ring-shaped enlarged cable 4o is supported in the chamber in an appropriate manner by means of needle bearings 45, and the output shaft 41 extends out of an end opening 46 which is sealed to the appropriate V / o is e by means of an O-ring 47, Thus, in the exemplary embodiment shown, the shaft 41 rotates at a speed that is 1/6 the speed of the reversing element 2-, namely in the opposite direction. The output shaft 41 thus only uses the rotational component of the rotor 16 and not its rail coraponent.

Actuator 95 continues to extend through axial opening in the sealing plate 62 therethrough Connection of the rotor 57 to the shaft 9o via the actuating member 95 is used to transmit rotary movements between the shaft 9o and the Hotor 57 »whereby the path component the rotor 57 is filtered out or not transmitted, in particular in the case in which the rotor when the device is used as a motor, drives the shaft 9o · In the case of use as a pump, the Hotor 57 “while the Vtelle 90 turns him, one more Path movement off · The connection of the actuator by means of the files 96 and, which are provided with wedges and hats 97 in effect creates an articulated connection at each of these points.

The actuating member 95 is provided with an extension which acts as a continuation of the actuating member extends beyond the rotor 57 and in the axis of the Actuator 95 is located and is offset from the axis 54 of the stator 53 or the housing 5o by a distance, which is greater than the distance by which the Hotor axis is offset from the stator axis 54 As described below, this extension creates an eccentric drive with respect to the stator axis 54 and it serves for this purpose, the eccentric drive at least with reference to a corresponding part of the extension at the point at which it leaves the rotor 57, to be translated or

In the uncontrolling element 7o a wall is provided which delimits a drive opening 1o1 in which the end of the extension 99 is received. This connection or this eccentric drive serves to rotate the Uiiisteuerorganans 7o in accordance with the orbital movement of the rotor 57. In other words, when the rotor axis 58 revolves around the stator axis 54, the extension 99 must also revolve around the stator axis 54 and causes at this movement is a rotation of the reversing member 7o about the pin 86, which rotates the reversing member 7o. The extension 99 continues to rotate in accordance with the rotation of the motor 57 _f, however, it only rotates relative to the drive opening 1o1, since there is no engagement to transmit the rotary movement of the rotor and the rotary movement is actually made ineffective or eliminated.

When using the device according to the above Description of the drive of the reversing element 7o, where this device is described as an eccentric drive, it is void that the drive, in order to be effective, too does not lead to an eccentric lock. This is described below in connection with FIG. Pig.

A common coefficient of friction of 0.18 has been assumed for the friction in the case of a response to traditional metal-to-metal Jier uHg. Since in this Pall Ic ₁ the coefficient of friction for the contact between the pin 86 and the opening 87 in which the pin 86 is arranged, and k _{2 is} the coefficient of friction for the contact between the extension 99 and the opening 1o1 in which
