摘要： A proportional solenoid valve includes a valve body defining an inlet and an outlet for a fluid flow through the valve body and an armature that is moveable along a longitudinal axis from a first closed position to a second open position to control the flow of fluid through the valve. The valve further includes a flux can and an encapsulated coil assembly encompassed within the flux can. The encapsulated coil assembly includes a bobbin, a wire coil wound around the bobbin, and a non-conductive encapsulation layer that encapsulates the bobbin and the wire coil so as to electrically isolate the wire coil from the flux can and other conductive components of the valve. When the solenoid coil is energized, a magnetic field is created which causes the armature to move away from the first position against the valve body toward the second position, thereby opening the valve. The proportional solenoid further includes insulated wiring that is electrically connected to the wire coil, and a non-conductive encapsulation tower that encapsulates the insulated wiring so as to electrically isolate the insulated wiring from the flux can and other conductive components of the valve.

摘要： A solenoid proportional valve includes a valve body defining an inlet and an outlet for a fluid flow through the valve body, and an armature that is moveable along a longitudinal axis from a first closed position to a second open position to control the flow of fluid through the valve. The valve further includes a flux can and a solenoid coil positioned within the flux can. When the solenoid coil is energized, a magnetic field causes the armature to move away from the first position against the valve body, thereby opening the valve. The valve may include an isolator configured to isolate the solenoid coil from a wetting path of the fluid flow. The isolator may include an isolator frame that generally conforms to a shape of the solenoid coil, and sealing elements configured to prevent a fluid flow from contacting the solenoid coil.

摘要： A pump/compressor includes at least one piston assembly for pumping a fluid from a fluid inlet to a fluid outlet, a housing configured to support the piston assembly, and an eccentric actuator that is enclosed within the housing. The piston assembly includes a glass cylinder, and a graphite piston that is actuated by the eccentric actuator to move within the glass cylinder, wherein movement of the piston drives the fluid from the fluid inlet to the fluid outlet. A motor drives a drive shaft that in turn drives the eccentric actuator to actuate the graphite piston. A housing cover of the housing receives a motor shaft support bearing that supports an end of the drive shaft opposite from an end that is driven by the motor. The pump/compressor may be a twin head pump/compressor with two oppositely positioned piston assemblies actuated by a split eccentric actuator.

摘要： A pinch valve meters fluid flowing through at least one tube. The valve utilizes an actuator assembly (20) comprising a piezo-electric member and a displacement amplifying structure to control a pinch member (40) movable against the tube for varying the cross-sectional area of the by pinching the flexible tube member against the tube housing body. Flow through the tube is proportional to the input voltage of the actuator assembly.

摘要： A solenoid proportional valve includes a valve body (12) defining an inlet (14) and an outlet (16) for a fluid flow through the valve body, and an armature (22) that is moveable along a longitudinal axis from a first closed position to a second open position to control the flow of fluid through the valve. The valve further includes a flux can (32) and a solenoid coil (30) positioned within the flux can. When the solenoid coil is energized, a magnetic field causes the armature to move away from the first position against the valve body, thereby opening the valve. The valve further includes a flux washer (28) that acts as a spring pivot for a spring (26) having an outer edge that is secured by the flux washer. When the solenoid coil is energized, the magnetic field causes the armature to move away from the first position against the spring force of the spring, thereby opening the valve.

摘要： An inert linear shear valve is presented for fluidly coupling at least two flow passages. The linear shear valve includes an actuation device (12) that moves a sliding plate (24) to a position where the at least two flow passage (16,18,20) are fluidly coupled. The sliding plate (24) is biased towards a manifold (14) containing the flow passages (16,18,20) by at least one resilient member (28,30) housed in a carrier (22). The sliding plate (24) has a minimal contact area with the manifold to minimize wear of the sliding plate 24) and the manifold (14).
