摘要： An electromagnetic proportional 2-way flow control valve (1) has a valve housing (2) in which a control piston (3) is guided to be displaced axially. The control piston (3) actuates at least one fluid-conducting connection (4) between a fluid inlet (5) and an outflow opening (6). An armature (8) can be actuated by a proportional magnet and acts on the control piston (3). A pressure detecting piston (9) serves as the actuator part on the control piston (3).

摘要： A pressure compensated electromagnetic proportional directional flow control valve of the present invention integrally includes: an electromagnetic proportional directional flow control valve configured to be driven by a solenoid; and a pressure compensated valve configured to carry out pressure compensation of a flow rate controlled by the electromagnetic proportional directional flow control valve. A pressure compensation spool moves so as to balance forces of a spring, a first pressure chamber, and a second pressure chamber. With this, the pressure compensation for maintaining a constant pressure difference between an upstream side and a downstream side of a first variable aperture can be carried out, and a surplus liquid of a liquid flowing from a liquid-pressure supply port to a derivation port can flow out from a branch port to outside.

摘要： The invention relates to a proportional throttle valve comprising a valve piston (2) which is displaceably guided in the longitudinal direction in a valve housing (3) having a fluid inlet (4) and a fluid outlet (5) and is pretensioned by an energy accumulator, in particular in the form of a pressure spring, against a stroke stop (6) defining the closure position. The invention is characterized in that a pressure limiting valve (7) is integrated in the proportional throttle valve (1), wherein said pressure limiting valve allows to influence the fluid pressure on the rear side (8) of the valve piston (2) in order to allow the piston to move away from the stroke stop (6) in opposition to the pretensioning force when a predefinable pressure is exceeded at the fluid inlet (4).

摘要： A proportional pressure control valve particularly for electro-hydraulic transmissions. The valve includes a cage having pump, clutch, and tank port openings. A spool is received within the cage for controlling flow between the clutch port and the pump and tank ports of the system. The spool has a feedback pressure surface responsive to an applied feedback fluid pressure urging the spool to move towards a first position allowing flow between the clutch and tank ports. A feedback pressure chamber is defined within the cage for developing the feedback fluid pressure. A clutch port pressure feedback passage couples the clutch port with the feedback pressure chamber for admitting flow from the clutch port into the feedback pressure chamber to develop the feedback fluid pressure. The clutch port pressure feedback passage is formed within the cage wall to couple the control pressure chamber in fluid communication with the system clutch port.
