摘要： A rotary gate valve, in particular for servo-assisted steering systems in motor vehicles, has a rotary distributor (2) which can rotate in a control bush (1). The control bush (1) and the rotary distributor (2) are provided with longitudinal control grooves (3, 4, 7, 8) which co-operate to control the flow of a hydraulic fluid in a hydraulic fluid reservoir to and from a servo motor. Co-operating control edges (5, 10 and 6, 11, respectively) of the longitudinal control grooves (3, 4, 7, 8) of the control bush (1) and rotary distributor (2) are arranged parallel to each other. The control edges (5, 6) of the longitudinal control grooves (3, 4) of the control bush (1) and the control edges (10, 11) of the rotary distributor (2) are disposed conically with respect to each other in their longitudinal direction. To assemble the rotary gate valve, the control bush (1) and the rotary distributor (2) are first moved axially relative to each other into a position in which the valve characteristic curve adopts its ideal position in the tolerance field of the valve characteristic curves and the control bush (1) and the rotary distributor (2) are then fixed in their axially facing positions.

摘要： In a power-assisted rack and pinion steering system designed especially for motor vehicles, a pinion (2) fitted in a steering box (1) engages with a rack (6). To provide power assistance there is a servo-motor (8), the piston rod (10) of which is operationally connected with the rack (6). A control device (18) to control a pressure medium to and from the servo-motor can be adjusted dependently upon a movement of the pinion (2). Both working chambers (12, 13) of the servo-motor (8) are connected to the control device (18) via working lines (14, 15) which are connected to a cylinder (11) of the servo-motor (8) and the control device (18) via two connectors (24, 25). Each working line (14, 15), besides a pressure line (26) from a servo-pump (21) and a return line (27) to a container (23), has a collar (32). Each line is held to the connector (24, 25) by a retaining clasp (34) surrounding the collar (32). For securing purposes, a tab-like extension to the retaining clasp (34) is elastically or plastically deformed after fitting.

摘要： A rotary slide valve presents a rotary slide (2) rotatably mounted in a control bush (1). Both parts are linked to each other by a torsion bar spring (3). A centering means (4) connected side by side with the torsion bar spring (3) acts upon the rotary slide (2). A centering spring (5) is formed therefor as a leaf spring attached to a cylindrical extension (8) of the rotary slide (2). The control bush (1) presents a conical recess (11) on its front face. A corresponding recess (10) is formed in the leaf spring part of the centering spring (5). A ball (12) is retained between both recesses (10, 11).

摘要： Centering device for assemblies provided with two counter-rotating parts, comprising a torsion bar spring (1), the central torsion region (2) of which has a reduced cross-section. At the ends of the torsion bar spring (1) are provided support regions (3, 4), on which are secured connecting parts (5, 6) for a connection between the centering device and the two parts of the assembly. The connecting parts (5, 6) carry sleeve-shaped extensions (9, 10), which surround without contact the torsion bar springs in their torsion region (2). Connected parallel to the torsion bar spring (1) is a torsion-resistant metal bellows (11) with an axial spring action, which is arranged coaxially to the torsion bar spring (1). The metal bellows (1) is linked at one of its ends with the sleeve-shaped projection (9) of one of the connection parts (5) at its other end the metal bellows (11) is connected with a first centering piece (12) of a central position locking device (13). A second centering piece (14) of the central position locking device (13) is linked with the sleeve-shaped extension (10) of the other connecting part (10).

摘要： In the proposed rack and pinion power steering gear system, which is intended in particular for motor vehicles, a pinion (2) mounted in a steering gear housing (1) meshes with a toothed rack (6). A servo-motor (8) is provided for power assistance, the piston rod (10) of the servo-motor being connected to the toothed rack (6) so as to drive it. The two working chambers (12, 13) of the servo-motor (8) are connected to a control device (18) via main lines (14, 15) which are connected to a cylinder (11) of the servo-motor (8) and to the control device (18) via two connecting elements (24, 25). Each main line (14, 15) has a collar (32). Each line is held on the connecting element (24, 25) by a holding clasp (34) which surrounds the collar (32). The holding clasp (34) has a substantially rectangular and smooth base (35). The base (35) has a longitudinal slit (36) open to one side, through which the holding clasp (34) can be pushed from the side over the line (14, 15) and the connecting element (24, 25). The holding clasp (34) also has two extensions (38) with edge beading projecting from the base (35), these extensions lying substantially parallel to the longitudinal sides of the longitudinal slit (36). The extensions (38) are designed to exert spring pressure both in the direction perpendicular to the base (35) and in the direction perpendicular to the longitudinal sides of the longitudinal slit (36).

摘要： A rotary slide valve (1) for power-assisted steering of motor vehicles contains in a valve bore (5) of a valve cage (2) a rotary slide (4) linked to a steering shaft connection (23). A control bushing (7) can swivel over a limited angle in an axial bore (6) of the rotary slide (4). The rotary slide (4) has control longitudinal grooves (20) arranged in its axial bore (6) that cooperate with control longitudinal grooves (21) on the outer surface of the casing of the control bushing (7). The internal control bushing (7) is manufactured by a non-cutting forming process and can thus have relatively small dimensions. Both the control longitudinal grooves (21) and the control edges of the control bushing (7) may be manufactured by such a process, for example by cold forming. Thanks to the relatively small dimensions of the control bushing (7), the whole rotary slide valve (1) may be very compact.

摘要： A centring device for steering valves comprises a torsion bar (1) firmly secured at one end-piece (1A) to a drive shaft (3) and at another endpiece (1B) to a drive shaft (4). As the torsion bar (1) cannot provide exact centring between a rotary valve (3A) and a valve bush (6), a fine-centring system is provided. The fine-centring system consists of a tubular end-piece (7) secured to the drive shaft and bearing a metal bellows (8) and a centring member (10) connected thereto. The centring member (10) is axially prestressed by the metal bellows (8) and presses against another centring member (14) via rollers (12). The centring member (14) is, according to the invention, part of an inner race (15) of a needle-roller bearing (16) which is pressed on the end piece (1B) of the torsion bar (2) connected to the drive shaft (3). The centring members (10, 14) have oblique surface grooves (11, 13) which generate a centring force via the rollers when the two shafts (3, 4) are mutually rotated.
