    1393930 Power steeing MITSUBISHI KINZOKU KK 21 Dec 1972 [27 Dec 1971 (2)] 59114/72 Heading B7H In a rotary type servo steering mechanism, Fig. 3, a torque is applied to an input shaft 2 by the provision of a partitioned hydraulic chamber 6 provided on the outer periphery of the shaft 2, the portions 6a, 6b being connected by passages formed in a concentric output member 3 to hydraulic drive chambers 4b, 4d and 4a, 4c respectively and to a servo valve mechanism including grooves 8, 9 formed in the output member 3. These grooves 8, 9 are in sliding contact with grooves 5a-5c formed in the input shaft 2, the groove 5a serving a feeding oil passage 16 and the grooves 5b, 5c for discharging oil via passages 17. The drive chambers 4a-4d are formed by partition walls 12A, 12B and 13A, 13B formed integrally with the casing 1 and output member 3 respectively. In Fig. 3 the input shaft has been rotated clockwise so causing chambers 4a, 4c to be pressurized and chambers 4b, 4d to be discharged resulting in clockwise rotation of output member 3. Also, portion 6b of chamber 6 becomes pressurized and portion 6a discharged providing a torque to hinder further clockwise rotation of the input shaft. If required the chamber 6 can be provided on the inner surface of the driven member 3. In a modification, Figs. 4, 6 an auxiliary body 30 is made integral with the casing 1 and has auxiliary chambers 104a-104d formed by partition walls 110a-110b and 111a, 111b formed integrally with the body 30 and input shaft 2. The auxiliary chambers 104a-104d are in fluid communication with main chambers 4a- 4d so that a torque is applied on shaft 2 in proportion to the pressure produced in the main chambers 4a-4d.

    (5) HYDRAULIC SERVOMECHANISM
    The invention relates to mechanical engineering, in particular to power hydraulic actuators, and can be used in the drive of the steering of a vehicle.s
    A hydraulic servo mechanism is known (4 types, containing a hollow cylindrical body, closed at the ends and having at least one separating wall located radially in the body in the plane of its central axis, passing concentrically through the body the input shaft and the output element located inside the housing 5 for rotation, on the input shaft and on the inspections one end of the housing and at least one separating blade protruding in the radial direction and 20 with the inner surface of the housing, the servo valve mechanism, located between the mating surfaces of the input shaft and the output element, is formed by a counter-GRANGE TYPE
    but arranged longitudinal grooves made in the input shaft and the output element, and associated respectively with the fluid supply and discharge channels and at least one pair of working cavities formed between the housing, its dividing wall and the output element, and a device for creating and loading on the input shaft l3.
    A disadvantage of the known device is that it has considerable dimensions, since the device for creating a load on the input shaft is formed by a part of the separating blade that protrudes into the interior of the input shaft.
    The aim of the invention is to increase the compactness.

    Claims (2)
    [1]
    This goal is achieved in that the device for creating a load on the input shaft is made in the form of at least one pair of reaction chambers formed by the radial surfaces of the input shaft and the output element 3 and associated with opposite working cavities. The reaction chambers are made in the form of a radial groove on the outer surface of the input shaft, which is additionally separated by a blade, which is additionally placed in a not and fixed on the output element. Figure 1 shows the proposed hydraulic rotary servomechanism in the neutral position, cross section; FIG. 2 shows A-A in FIG. Fig. 3 shows a hydraulic servo-mechanism of a rotary type with rotation of the input shaft and the output element, cross section. The rotary type hydraulic servo-mechanism contains a hollow central body 1 closed at the ends with covers 2, passing concentrically the input shaft 3 and the output element A,; The valve mechanism 5 and the device 6 for generating a load on the input shaft. The housing 1 has dividing walls 7 located in the housing in the radial direction in the plane of its central axis 8; The output element 4 is located inside the housing 1 rotatably on the input shaft 3 and has an outlet 9 y y; 1 from the housing 9 and dividing lobes 10, protruding radially and adjacent to the inner surface 11 of the housing 1. The servo valve mechanism 5 is located between the mating surfaces 12 and 13 of the input shaft 3 and the output element A and is formed by opposing grooves formed in them. The groove 1 is connected by channels 19 with the working cavities 20, and the groove 15 by channels 21 is connected with the working cavities 22. The groove 16 and 18 of the serval-valve mechanism 5 is connected to the liquid withdrawal channel 23, and the groove 17 is connected to the liquid supply channel 2A Device 6 to create a load on the input shaft 3 is made in the form of a pair of reaction chambers 25 and 2b, formed by radial surfaces 13 and 27. The reaction chambers are placed in a radial groove 28, made on the outer surface 12 of the input shaft 3 "Chambers 25 and 26 times placed in the slot 28 of the blade 4 29, mounted on the output element t, hydraulic servomechanism rotary type operates as follows: In the initial position of the input shaft 3 is in a position k of the output member carries significant that the slots 14 - 18 are blocked. No liquid enters the servo and the protruding end 9 of the output element 4 does not rotate. When the input shaft is rotated clockwise (FIG. 3), the groove 14 on the input shaft is aligned with the groove 17 on the output element and the fluid from the fluid supply channel 24 enters via channels 21 into the working cavity 22 associated with the reaction chamber 26. Under this the action of the incoming fluid begins to rotate the blade 10 and the output element 4 monitors the rotation of the input shaft. On the input shaft 3, a reaction moment occurs, directed in the opposite direction of rotation. The working fluid displaced from the cavities 20 through the channels 19 through the grooves 14 and 16 flows into the fluid outlet channel 23. When the rotation of the input shaft 3 is stopped, the output element 4, having caught up with it, closes the slots l4-l8 and also stops. When the input shaft is rotated counterclockwise, the liquid enters the working cavities 20 and rotates the output element 4 in the same direction. The reaction chamber 25 creates a load on the input shaft 3. When stopping the spraying shaft 3, the element 4 also stops. The proposed implementation of the servo-mechanism allows creating a compact design that provides reaction load on the input shaft, which improves the drive control conditions. Claim 1. Hydraulic servo-mechanism of rotational type, comprising a hollow cylindrical body, closed at the ends and having at least one separation wall located radially in the body in the plane of its central axis, passing concentrically through the body the input shaft and the output element located inside the housing with the possibility of rotation on the input shaft and having one end coming out of the housing and at least one separating blade protruding in the radial direction and matching A servovalve mechanism, located between the mating surfaces of the input shaft and the output element, formed with oppositely arranged longitudinal grooves made in the input shaft and the output element, and connected respectively to the fluid supply and bypass channels and at least one pair of working cavities formed between the housing, its dividing wall and the input element, and a device for applying a load on the input shaft, characterized in that Vyshen compactness, the device for generating a load on the input shaft is in the form of at least one pair of reaction chambers formed by the radial surfaces of the input shaft and the output member and coupled with opposite working cavities;
