    摘要： A rotatable control device or valve including a body housing a control mechanism and a rotatably mounted control shaft connected to the control mechanism. Stops are spaced circumferentially relative to the control shaft. A stop arm is operably connected to the control shaft and engages the stops to limit rotational movement of the control mechanism between first and second positions. An elongated extension is drivingly connected to the stop arm, and an elongated operating handle is connected to the extension with the orientation of the longitudinal axis of the operating handle corresponding in a predetermined relationship to the position of the control member. A registration mechanism permits the extension to be drivingly connected to the stop arm only when the orientation of the longitudinal axis of the operating handle corresponds in the predetermined relationship to the position of the control means.

    摘要： A motor vehicle power steering gear having a spool shaft connected to a steering wheel, a pinion head connected to a steered wheel, a torsion bar between the spool shaft and the pinion head, a control valve for regulating a hydraulic steering assist boost pressure in response to rotation of the spool shaft from an on-center position relative to the pinion head against a restoring force of the torsion bar, and a quiet preload apparatus including a C-shaped spring around the spool shaft having a pair of resilient jaws, a drive pin on the spool shaft clamped with a preload between the resilient jaws, and a cushioned abutment on the pinion head clamped with the preload between the resilient jaws. The cushioned abutment includes a pair of radial cantilever springs which flex upon engagement with corresponding ones of the resilient jaws during forced oscillation of the pinion head back and forth through the on-center relative position of the spool shaft to minimize audible noise associated with such engagements and a radial reinforcement between the cantilever springs which limits flexure thereof to minimize the effect of the cantilever springs on the performance characteristics of the control valve.

    摘要： A tamper-proof locking mechanism for a rotatable control device, such as a quarter turn valve, including a valve member connected to a stem rotatably mounted in a body housing the valve member and an operating handle connected to the stem via an elongated extension for rotating the valve member between open and closed positions. The locking mechanism includes a bracket mounted on the body and having a flange spaced outwardly from the body and generally perpendicularly to the rotational axis of the stem and including an aperture through which the extension extends and a pair of circumferentially spaced projections extending radially outwardly relative to the rotational axis of the stem at locations corresponding to the open and closed positions of the valve member. A slider member, slidably mounted on the intermediate portion of the handle for reciprocating movement between locked and unlocked positions, includes a latch element having an opening for receiving the projections and arranged to restrain both rotational and axial movement of the handle when the handle is in the open or closed position and the slider member is in the locked position.
