摘要： A valve (10) for controlling flow of hydraulic fluid. The valve (10) has first and second valve members (80, 82) which have a plurality of lands and grooves. The valve members (80, 82) are relatively movable from a neutral position to a displaced position in which surface segments (202, 226, 208, 218) of respective pairs of lands overlap to form flow gaps (232, 234) for restricting flow of fluid between respective pairs of grooves. At least one (234) of the flow gaps is divergent by having a cross-sectional flow area which increases along a direction of fluid flow and at least one (232) of the flow gaps is convergent by having a cross-sectional flow area which decreases along a direction of fluid flow. The flow gaps (232, 234) have minimum cross-sectional flow areas (A, B) defined by the surface segments. The flow gaps (232, 234) are sized such that the minimum cross-sectional flow area (A) of the convergent flow gap (232) is larger than the minimum cross-sectional flow area (B) of the divergent flow gap (234) for suppressing valve noise.

摘要： A valve for controlling flow of hydraulic fluid. The valve includes first and second relatively movable valve members (60 and 62). The valve members (60 and 62) include cooperating surfaces (112, 142, 144) which define first and second orifices for metering fluid from a pressurized fluid source (44) toward first and second locations (22 and 24) in a fluid utilization device (12). The valve members (60 and 62) have a displaced position in which the first orifice is increased in size and the second orifice is decreased in size. The increased size of the first orifice reduces a pressure drop across the first orifice. The decreased size of the second orifices increases a pressure drop across the second orifice. The valve members (60 and 62) include means (114 and 146) for increasing a pressure on a downstream side of the second orifice to reduce the pressure drop for controlling valve noise.

摘要： A power steering assembly (10) includes a rotatable valve core (40) which is encircled by a rotatable valve sleeve (41). The valve core (40) and valve sleeve (41) have surfaces which cooperate to direct a flow of power steering fluid during relative rotation between the valve core (40) and valve sleeve (41). A bearing assembly (100) is disposed between the valve core (40) and the valve sleeve (41) at a location adjacent to an axially outer end portion of the valve core (40). The bearing assembly (100) includes a plurality of rotatable bearing elements (124) which transmit sidewise loads between the valve core (40) and the valve sleeve (41). A bearing surface (102) is disposed on an axially inner end portion of the valve core (40). The bearing surface (102) is slidable along an inner surface area (104) on the valve sleeve (41) to transmit a sidewise load during relative rotation between the valve core (40) and the valve sleeve (41).

摘要： A hydraulic power steering gear (10) for a vehicle comprises first and second valve members (40 and 42) which are disposed coaxial to one another and which are relatively rotatable about a first axis (38) to selectively port hydraulic fluid. The first valve member (40) has an associated axial bore (170). The axial bore (170) has a second axis (174) which extends parallel to the first axis (38). The second valve member (42) includes a cam surface (128). A plunger (200) is disposed in the axial bore (170) for movement along the second axis (174). The plunger has a detent surface (208). Springs (240) bias the plunger (200) axially toward the second valve member (42). A detent roller (220) acts between the first and second valve members (40 and 42). The detent roller (220) is located in the cam surface (128) and in the detent surface (208) in a neutral condition to provide a physically perceptible indication to a driver of the vehicle of operation between the neutral condition and an actuated condition.

摘要： To adjust the maximum torque required to actuate a hydraulic steering mechanism, the steering mechanism is first adjusted to provide a relatively high preload on gear teeth in the steering mechanism. The steering mechanism is then operated through a predetermined number of break-in cycles. After oil has been purged from the steering mechanism the steering mechanism is operated through one complete operating cycle and the location where the maximum torque is required to effect operation of the steering mechanism is noted. Preload between the gear teeth is then reduced and the steering mechanism is operated to the position where it was previously noted that maximum torque was required to actuate the steering mechanism. The steering mechanism is there dithered to either side of the location where the maximum torque was required. As this is done, the steering mechanism is adjusted to obtain the desired maximum operating torque for the steering mechanism.

摘要： A first locator engages lands defining a first groove in a valve core to position that first groove accurately relative to a first pair of notch forming tools. The first pair of notch forming tools then engage axially extending edges of lands defining that first groove to form metering notches. The first locator and first pair of notch forming tools are disengaged from the valve core. Then, a second locator engages lands defining a second groove to accurately position the valve core relative to a second pair of notch forming tools. The second pair of notch forming tools engage the valve core to form metering notches in the edges of lands defining the second groove. The second locator and second set of notch forming tools are retracted from engagement with the valve core. Thus, the metering notches are precisely and independently formed relative to each land.

摘要： An improved valve assembly (100) includes a primary spring (142) which extends along a valve stem (144). A spring retainer (150) holds the primary spring (142) on the valve stem (144) and has a thread convolution (152) which engages a thread convolution (154) on the valve stem (144). The spring retainer (150) has a force transmitting surface (182) which engages a reference surface (184) on the valve stem (144) with a retainer preload force which is at least as great as a primary spring preload force. Shims (158–162) are provided between the primary spring (142) and the spring retainer (150) to enable a desired primary spring preload force to be obtained.

摘要： An apparatus (10) for use in turning steerable wheels of a vehicle having an engine includes a first gear (16) which is rotatable about a first axis (24) and a second gear (14) having teeth (20) in meshing engagement with teeth (18) on the first gear (16). The first gear (16) is movable along the first axis (24) to reduce clearance between the teeth (18) and (20) of the first and second gears (16) and (14). Adjustment of the first gear (16) along the first axis (24) is prevented during operation of the engine of the vehicle. Adjustment of the first gear (16) along the first axis (24) is enabled when the engine of the vehicle is in a non-operational condition.
