    Abstract: The invention relates to a controlled three-way proportional valve unit comprising: a valve assembly with two individual valves; an actuating device actuating valves of the valve assembly; and a control unit acting upon the actuating device and having a control signal input, the valves of the valve assembly being designed as poppet valves arranged on opposite sides and having counter-rotatable valve spindles. The valve spindles are prestressed relative each other in opposite directions by a prestressing element such that, when the actuating unit is inactive, a first poppet valve is open and the second poppet valve is closed. The actuating device comprises an actuator common to both poppet valves, acts upon the two valve spindles and changes the position of the valve spindles counter to the effect of the prestressing element.

    Abstract: A pilot valve configured to provide a control pressure within a dynamic fluid system, the pilot valve comprising: (a) a valve body having a supply port, a return port, and a control pressure port, the pressure control port in fluid communication with a subsequent valving component; (b) an axial bore formed in the valve body and in fluid communication with each of the supply, return, and control pressure ports; (c) a valve spool slidably supported within the axial bore of the valve body, the valve spool configured to control fluid flow through the supply, return, and control pressure ports, and to vary the rate of change of area of at least one of the supply and return pressure ports upon being displaced, thereby providing a variable resistance to fluid flowing therethrough and reducing the quiescent power of the pilot valve; and (d) means for displacing, in a selective manner, the valve spool within the axial bore about the supply, return, and control pressure ports to apportion fluid therethrough to provide a desired control pressure to the subsequent valving component. The pilot valve further comprises a feedback port formed in the valve body and in fluid communication with the control pressure port; and a feedback passage in fluid communication with the feedback port and a portion of the valve spool, the feedback passage configured to receive pressurized fluid therein to act against the valve spool to balance the forces acting on the valve spool from the motor.

    Abstract: A solenoid actuated valve assembly includes a valve body having a slidable main valve member and a pilot valve body mechanically connected to the valve body including a slidable pilot valve member. A first solenoid operated valve connected to the pilot valve body when energized directs pressurized fluid to move the pilot valve member between pilot valve open and closed positions. A second solenoid operated valve connected to the valve body when simultaneously energized with the first valve directs the fluid to move the main valve member between valve closed and open positions. A third solenoid operated valve connected to the pilot valve body when energized and when both the first and second solenoid operated valves are de-energized directs the fluid to move the pilot valve to the pilot valve open position and the main valve member to the valve closed position.
