摘要： A proportioning valve assembly employs an electromagnetic acuator, such as a proportioning solenoid, associated with a driver circuit. The driver circuit is provided a lead phase circuit for providing a lead phase in supplying a supply current for controlling the valve position of the proportioning valve. Providing appropriate lead time reduces necessity of high gain in attitude change suppression mode operation. Therefore, the response characteristics in pressure adjustment in the shock absorbing mode operation, can be prevented from falling an excessive level.

摘要： A torque is transmitted between a fluid pressure pump driven together with drive of a vehicle, and a fluid pressure motor that rotates together with driven wheels. The fluid pressure motor has two ports, and rotates in accordance with the direction of fluid supply to the ports. Fluid is circulated from one port to the other according to the input of rotation torque from the driven wheels. A high pressure flowpath connected to the pump outlet, and a low pressure flowpath connected to the pump inlet, are connected to these ports, and the connection direction is reversed when the rotation direction of the drive wheels is reversed. The low pressure flowpath is therefore always at low pressure regardless of the rotation direction of the drive wheels, and by controlling the pump supply flowrate so as not to exceed a predetermined value, torque is not transmitted when the vehicle is running at high speed.

摘要： A pressure control valve unit to be employed in an active suspension system includes a valve member movable between a pressure increasing mode position, a pressure decreasing mode position and a pressure holding mode position for adjusting fluid pressure in a working chamber of an active cylinder disposed between a vehicular body and a suspension member rotatably supporting a road wheel.

摘要： A pressure control valve for adjusting a controlled pressure supplied to an actuator includes first and second valves. The first valve serves to modify a pressure level of a working fluid supplied from a fluid pressure source to a preselected level and provides it to the actuator. The second valve is responsive to a control signal commanding elevation or reduction in the controlled pressure from a controller to adjust a supply pressure level from the fluid pressure source to provide a pilot pressure, elevated or reduced to a preselected level, to the first valve for activating same. When elevating or reducing the pilot pressure, the second valve decreases the supply pressure level from the fluid pressure source by a preselected degree, for balancing a flow gain when elevating the pilot pressure with that when reducing the pilot pressure, for providing uniform response for elevation and reduction of the controlled pressure to the actuator.
