Abstract: A proportional solenoid-controlled fluid valve assembly having a fluid pressure balancing diaphragm. The valve assembly also includes a solenoid coil assembly having a cylindrical conduit and a magnetic orifice piece positioned within the conduit. A plunger is positioned within the conduit and is movable within the conduit between a de-actuated position and an actuated position. A pressure balancing diaphragm is provided having a top side, a bottom side, an outer annular flange portion, a U-shaped portion, and an inner annular flange terminating at a diaphragm opening, with the diaphragm being positioned within valve base with the outer annular flange portion abutting the ledge of the valve base and the U-shaped portion abutting the valve seat. A retainer is also provided having a top cylindrical upstanding portion extending through the diaphragm opening and an aperture formed in the plunger. A magnetic frame is also included for securing the valve assembly in an assembled configuration, wherein a magnetic path is formed by magnetic orifice piece, plunger and the magnetic frame and the solenoid coil is configured to be actuated such that the plunger moves towards the magnetic orifice piece, thus lifting the diaphragm and retainer and allowing pressurized media to pass from the inlet port to the outlet port.

Abstract: A valve assembly includes a valve base having a tubular section with a longitudinal bore formed therein, a fluid inlet port and a common port with an internal passageway therebetween. A solenoid coil is adapted to generate a magnetic flux and includes a longitudinal axis and a bore coaxial therewith. The valve assembly further includes an orifice piece positioned within the longitudinal bore of the valve base. The orifice piece includes a central passageway with a first end and a second end. A plunger is movable within the longitudinal bore between a first de-actuated position and a second actuated position.

Abstract: A rectilinear motion proportional solenoid assembly includes a cylindrical housing containing an electromagnetic coil having a longitudinal coaxial bore. The housing contains magnetic material for providing a flux path for the magnetic field produced by the coil. A generally cylindrical magnetic pole piece element is inserted into the bore and a movable armature assembly of magnetic material is supported within the bore for movement along the longitudinal axis of the coil by a pair of thin, flexible suspension springs. One of the springs is located within the bore adjacent to one end of the magnetic pole piece whereat an axial gap between the pole piece and the armature is formed. A second spring is located within the housing within the vicinity of a radial air gap between the armature and the housing. The pole piece contains an auxiliary region adjacent to the axial air gap for shunting a portion of the axially directed magnetic flux, for effectively causing the force imparted to the movable armature by the application of a current to the electromagnetic coil to be substantially constant irrespective of the magnitude of the axial gap for a variation in the axial gap over a prescribed range.

Abstract: A pneumatic vacuum gripping assembly for attachment to a suction gripper device is coupled by way of a fluid flow link to a venturi for controlling the vacuum of the suction gripper device comprises an integrated housing assembly having a venturi and a pneumatic fluid-flow control valve unit. The valve unit controllably interrupts fluid communication between a main supply inlet port and the venturi and is controlled by the output of a pressure sensor that is integrated within the housing assembly. The assembly further includes a reset valve arranged in a compact, stack configuration with the other components of the valve unit and ported to the venturi vacuum line for controllably `blowing off` the suction gripper device from a gripped object.

Abstract: A solenoid-operated control valve has a main orifice and a valve member for controlling fluid flow therethrough. A leakage orifice extends through the valve member. A check valve seals the leakage orifice when the main orifice is blocked and moves to open the leakage orifice before the main orifice is opened.
