摘要： A valve has a valve piston (12) guided longitudinally movably in a valve housing (10) and actuated by an operation device (14). In one valve piston position, a connection is produced between a pressure supply port (P) and a working port (A). In another valve piston position, a further fluid-conducting connection is produced between the working port (A) and a tank port (T). The pressure difference arising between the working port (A) and the tank port (T) as flow passes through the further fluid-conducting connection acts, by an actuation device (30), on the valve piston (12). The valve piston passes from a stop position (32), with the further fluid-conducting connection shut off, into a fully open opening position with an enlarged opening cross section from working port (A) to tank port (T).

摘要： A hydraulic control circuit for a drive line includes first and second switching valves and first and second solenoid valves. Each switching valve is alternatively switched by a switching hydraulic pressure to connect any two of three ports. The first port of the first switching valve is connected to a hydraulic actuator. The first port of the second switching valve is connected to the second port of the first switching valve. The first solenoid valve supplies the switching hydraulic pressure to the switching valves. The second solenoid valve regulates a control hydraulic pressure supplied to the hydraulic actuator. Any one of three oil paths is communicated with the hydraulic actuator by supplying the control hydraulic pressure via the third port of the first switching valve or the second or third port of the second switching valve and supplying the switching hydraulic pressure to at least one switching valve.

摘要： A pressure control system of a torque control device comprises an electronic control device TCU (100), a control pressure regulating valve (110), a fixed pressure oil passage, a pressure switching valve (120) and a jointing pressure regulating valve (130). When a control pressure is lower than a set value of a spring of the pressure switching valve, the pressure switching valve connects a jointing pressure with a feedback interface (135) of the jointing pressure regulating valve (130) and a jointing pressure regulating valve (130) outputs the jointing pressure in direct proportion with a control signal; when the control pressure reaches the set value of the spring of the pressure switching valve, the pressure switching valve (120) connects a fixed pressure with the feedback interface (135) of the jointing pressure regulating valve and the jointing pressure regulating valve (130) communicates a main pressure interface (131) with a jointing pressure interface (136) to increase the acting area of the control pressure of the jointing pressure regulating valve (130) through switching of the pressure switching valve (120) or reduce the feedback area, so as to increase the change slope of the jointing pressure and ensure enough torque capacity.

摘要： A hydraulic clutch control device of a vehicle power unit in which the oil pressure control valve is prevented from being exposed above the oil level even when a vehicle body inclines frontward or rearward. A housing chamber housing an actuator is formed in a housing chamber forming body attached to an engine main body and an oil pressure control valve partially facing the housing chamber is supported by the housing chamber forming body. An oil return hole used to return excess hydraulic oil from the housing chamber into the engine main body is provided in the housing chamber forming body to communicate with an upper portion of the housing chamber at an end portion of the housing chamber on a side close to the oil pressure control valve.

摘要： A hydraulic control device configured with a source pressure generation section, a hydraulic servo for a clutch provided between an engine and a motor, a control solenoid valve that outputs a regulated source pressure to the hydraulic servo, and a switching section that switches a hydraulic passage, which extends between the source pressure generation section and the hydraulic servo to supply the engagement pressure, between a first and second state in which the hydraulic passage has a high conduit resistance compared to the first state at least until the clutch is engaged. The switching section switches the hydraulic passage into the second state during a failure in which the control solenoid valve is de-energized and the source pressure is directly supplied to the hydraulic servo as the engagement pressure, and switches the hydraulic passage into the first state during normal times when the failure does not occur.
