摘要： A hydraulic coupling (32) includes a control valve (80) that controls pumping from a casing inlet port (58) by a hydraulic pump (48) through a casing outlet port (78) to control operation of a clutch (68) for coupling between two rotary members. The casing (34) is connected to one of the rotary members while a pumping component embodied by an impeller (50) is connected to the other rotary member and meshed with an internal ring gear (54) having one more tooth than the number of impeller teeth to provide sufficient pumping capacity so that the pump can act as a brake while still having relatively constant pumping pressure. The control valve (80) includes a valve element (82) mounted within a recess (98) to provide accurate control of its closure when the pumped hydraulic fluid reaches a predetermined pressure corresponding to a predetermined extent of relative rotation between the two drivetrain members. The outlet port (78) is disclosed as extending through an actuating piston (72) of the clutch in certain embodiment and also through the casing back to the hydraulic pump in another embodiement to provide a supercharged circuit.

摘要： A hydraulic coupling (32) includes a control valve (80) that controls pumping from a casing inlet port (58) by a hydraulic pump (48) through a casing outlet port (78) to control coupling between two rotary members. The casing (34) is connected to one of the rotary members while an impeller (50) having between five and seven external teeth is connected to the other rotary member and meshed with an internal ring gear (54) having one more tooth than the number of impeller teeth to provide sufficient pumping capacity so that the pump can act as a brake while still having relatively constant pumping pressure. The control valve (80) includes a bimetallic valve element (82) that compensates for temperature changes and may also include a speed sensitive valve closure (104) for providing immediate coupling without delay above certain speeds of operation. Mounting of the bimetallic valve element (82) of control valve (80) within a recess (98) provides accurate control of the temperature compensation.

摘要： A control valve (80) of a hydraulic coupling (32) controls pumping from a casing inlet port (58) by a hydraulic pump (48) through a casing outlet port (78) to control coupling between two rotary members such as by operation of a clutch (68). The control valve (80) includes an elongated valve element (82) of a flat shape mounted within an inclined recess (98) to provide accurate control of its closure when the pumped hydraulic fluid reaches a predetermined pressure corresponding to a predetermined extent of relative rotation between the two drivetrain members. This elongated valve element (82) is made from a bimetallic strip so as to be temperature compensated and the outlet port (78) is provided with a main passage (94) as well as a bleed passage (96, 96') that is cleaned when the valve element is opened.
