摘要： A valve assembly comprised of a solenoid coil, having a coil bore, and being operative to produce a magnetic field when subject to an electric signal, a fixed magnetic pole piece within the coil bore, a generally cylindrically and axially translatable armature with a disc-shaped portion and an aperture therethrough, a valve base with a fixed portion over which the armature fits and forming a fluid cavity therebetween. The armature aperture allows a fluid to pass through the disc-shaped portion and into the fluid cavity to substantially equilibrate the fluid pressure on the armature in an axial direction. The valve assembly further includes a solenoid base which forms a chamber around the armature and a biasing mechanism between the magnetic pole piece and the armature which axially translates when the magnetic pole piece is subject to the electric signal, allowing the fluid to pass through the valve assembly in proportion to the electric current.

摘要： A proportional solenoid-driven valve control assembly comprised of a moveable, magnetic armature adjacent to a fixed magnetic pole piece, providing fluid leakage containment, and having no non-magnetic element for alignment, support, or magnetic flux path control. A valve unit coupled with the armature contains a fluid cavity in fluid communication with a fluid inlet port and a fluid exit port. The valve is closed by a poppet coupled to the armature. To compensate for fluid pressures exerted against the poppet, a flow restriction is provided between an armature cavity and the fluid cavity. In addition, a bore is formed through the armature to provide fluid communication between the fluid exit port and the armature cavity. This serves to balance fluid pressures at the fluid inlet and exit ports applied to the opposite sides of the fluid flow restriction.

摘要： A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed magnetic pole piece. The magnetic pole piece has a longitudinal axial pole piece portion, and a relatively thin, annular axial pole piece portion, that rapidly saturates, and is effectively mechanically solid with the longitudinal pole piece portion for fluid leakage containment. A radial portion is solid with the annular axial portion and provides support and alignment for the armature relative to the magnetic pole piece, without the need for non-magnetic material for alignment, support or magnetic flux flow path control.

摘要： 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.

摘要： A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed pole piece that protrudes from a solenoid bore and is supported by means of a pair of flat suspension springs adjacent to the one end of the bore. The movable armature is configured to provide two generally cylindrical radial magnetic flux paths. One flux path traverses a radial gap at one end of fixed magnetic pole piece that protrudes from the one end of the solenoid bore. The other flux path traverses a generally cylindrical gap between a rim portion of the armature and an inwardly projecting magnetic element of the solenoid housing. The two radially separate cylindrical gaps function as coaxial guide air-bushings for the moveable magnetic armature that prevent off-axis play between the moveable armature and the pole piece and the inwardly projecting magnetic element.

摘要： A proportional solenoid-driven valve control assembly contains a moveable, magnetic armature positioned adjacent to one end of a fixed pole piece that protrudes from a solenoid bore and is supported by means of a compact suspension spring arrangement adjacent to the one end of the bore. The movable armature is configured to provide two radial magnetic flux paths. One flux path traverses a fixed radial shunt gap at one end of fixed magnetic pole piece that is located in and protrudes from the one end of the solenoid bore. The other flux path traverses a variable geometry reluctance gap defined between a radially projecting, tapered rim portion of the armature and an inwardly projecting tapered portion of the solenoid assembly housing. The proportional solenoid assembly is mechanically coupled with a valve unit for electrically controlling its operation, in particular the flow of fluid between a fluid input port and a fluid exit port of the valve unit, in accordance with displacement of the movable armature along the solenoid assembly axis in proportion to the current applied to the solenoid.
