    A power steering control device includes a housing for receiving an input member and an output member which are rotatably disposed within a valve sleeve sealingly engaging the housing. The input member, output member and valve sleeve include axially aligning grooves for receiving at least one projection which limits the rotation of the input member, output member and valve sleeve relative to each other. The housing communicates with a fluid pressure source and the input member is rotatable relative to the valve sleeve such that the one projection cooperates with the input member and the valve sleeve to control fluid flow through the valve sleeve. Moreover, the input member, valve sleeve and one projection are releasably held together to form a unitary assembly which connects with the output member within the housing.

    The invention relates to hydraulics and is intended for vehicles.
    A hydraulic control valve is known, containing a 5-pus with a cylinder, a spool rotatably disposed in the cylinder, rotatable inlet and outlet elements, the inlet element being arranged to accommodate and limited | Q of rotated rotation in the inner cavity of the spool, and between at least one channel is formed by them into which fluid flows from a pressure source and in which a fixative pa-5 lex of Cl is placed. A disadvantage of the known valve is that the inlet and outlet elements with put the node complex for the preparation and installation.
    The purpose of isofenes is to simplify the manufacture and installation of the valve.
    The goal is achieved by the fact that the output element is designed as a separate part with the possibility of
    its axial grooves are made in the inner cavity of the zolotnnka and on its outer surface to accommodate the specified locking blade, while the spool, the inlet element and the locking finger are connected with the possibility of release by a pair of spring rings to equip a single knot inserted by Yahshlindr, the element is provided with a flange part, on the outer surface of which a groove is made, and the spring rings are in axial contact with the respective ends of said flange.
    FIG. 1 schematically shows the proposed valve (section A-D in FIG. 2); in fig. 2 is a section BB in FIG. one; in fig. 3 - valve disassembled, axonometric; in fig. 4 - valve with inlet valve; in fig. 5 is a section B-B in FIG. one.

    The valve includes a housing 1 with a cylinder 2, a spool 3 located with the possibility of rotation in the cylinder, a rotary inlet 4 and an output 5 electronets. The input element 4 is connected to a steering wheel (not shown) on the vehicle, and the output element 5 mounted on bearings 6 reports movement of the steering gear 7, for example a toothed rack, in the vehicle steering system. The output element 5 is fixed in the axial direction by a nut 8. For the compactness of the arrangement of elements 4 and 5 and their necessary alignment on the output element 5, iXBocToBHK 9 is made, which is included in the bore 10 in the input element 4. In cylinder 2 a cover 11 is installed. In elements 4 and 5 and the spool 3 are made axial grooves 12, 13 and 14, respectively, in which the fixing fingers 15 are installed. The input element 4 is provided with a flange part 16, on the outer surface of which a groove 17 is made. The spool 3, the input element 4 and fix The remaining palads 15 are associated with the ability to release a pair of spring rings 18 to form a single knot wedge inserted into the cylinder

    2. The rings 18 are in axial contact with the ends of the flange part 16, preventing the axial movement of the input element 4 relative to the fingers 15, which in turn are in frictional closure with the slide 3. The input element 4 has the ability to rotate in the inner the cavity of the spool 3, bounded by a spring 19, placed in the hole 20 of element 4 and the pistol cap 21 of the spool 3. In the zolonik 3, there is a through thread from the version 22, the outer ends of which are connected to the groove 23, opposite the inlet pipe 24 connected to the source 25, - pressure, for example, a pump. The other ends of the openings 22 communicate with the cavities 26 of the input element 4d, which are prices & prices with cavities 27 of the spool 3. In the spool 3 on both sides of the groove 14, the open ends 28 of which are connected with the grooves 29 and 30. The latter are located against output piping 31 and 32 connected to the cavity of the hydraulic actuator (not shown). Chutes 12 and 14 are also a conduit into which fluid flows from pressure source 25. The spring 19 acts in combination with the pressure of the fluid through the cavities 27 supplied to the reactive surfaces 33 to create resistance to relative rotation between the inlet 4 and the spool.
    [3]
    3. At the bottom of the grooves 12 on the inlet element 4, channels 34 are provided for draining the pressurized fluid from the cavities 27 to the outlet conduit 35 through a cavity 36 and the groove 37 in the lid 11. The grooves 13 and 14 are in shape with the curvature radius of the fingers 15, therefore the spool 3 and the output element 5 rotate simultaneously. The valve operates as follows. The pressure source 25 (pump) continuously supplies fluid to the hydraulic paths defined by the inlet pipe 24, the groove 23, (through the openings 22, cavities 26 and 27, canals 34, the groove 37) and the outlet pipe 35. When the valve elements are in rest, as shown, for example ,, in FIG. 2, the fluid passages for both sides of the fingers 15 are equal and the pressure in the grooves 29 and 30 is the same, therefore the hydraulic drive is inactive. After a slight angular mixing of the inlet element 4 with respect to the spool 3 (after steering the steering wheel), the flow area between one side of each cavity 27 and the corresponding channels 34 increases. In this way, unbalanced pressures are created between the cavities of the hydraulic drive, as a result of which the steering is strengthened. In the event of the cessation of supply of fluid under pressure due to a maligned connection or failure of the supply hydraulic pump, the input force can be directly transmitted to the output element by direct contact of the fixing fingers 15 with lateral angles of the grooves 12. The output element can be reduced as a separate part and connected to the input element to reduce costs for the manufacture and installation of the valve. Formula Shadow Invention Hydraulic control valve, supporting body with cylinder, spool rotatably located in cylinder, rotatable inlet and outlet elements, with snroM inlet element extensible with positioning and limited rotation in the inner cavity of the zootiotnik, and between them is at least at least one channel into which fluid flows from a pressure source KB which holds a locking pin, about one l and n and so that, in order to simplify the manufacture and assembly of the valve, in The exit element is in the form of a separate part with the possibility of placing it in the inner cavity of the pickup and on its outer surface axial grooves for U 54 of the specified locking pin, while the spool, Eosode element and locking finger are connected with possible. In addition, the inlet element is provided with a flange part, on the outer surface of which a groove is made, and the spring rings 5 are in axial contact with the respective ends of the said flange.
