摘要： A valve assembly includes a solenoid can having an internal coil. A valve body connected to the solenoid can includes an inlet port and a first valve seat. An axially adjustable retainer threadably connected to the valve body includes an end portion defining a second valve seat. A homogenous valve member/armature slidably disposed in the valve body moves in the presence of a coil generated magnetic flux between valve closed and valve open positions. A valve member/armature first surface area is in fluid communication with a pressurized fluid through the inlet port. A valve member/armature second surface area is in fluid communication with the pressurized fluid in the valve closed position. The first surface area is equal to the second surface area and the pressurized fluid acts equally on the first and second surface areas defining a pressure balanced condition in the valve closed position.

摘要： A self-latching solenoid valve assembly including a valve body having a pressurized air supply inlet port for communicating with a source of pressurized air and at least one cylinder port. A valve member is supported in the valve body so as to be movable between predetermined positions to selectively direct pressurized air from the inlet port to at least one cylinder port. A biasing member is employed to move the valve member in one direction and a solenoid assembly is used to move the valve member in an opposite direction. The solenoid assembly includes a housing with a solenoid coil supported therein and a fixed ferromagnetic pole piece having a passage extending therethrough with a pushpin movably supported in the passage. A ferromagnetic latch is also supported by the housing and spaced from the pole piece. A permanent magnet is disposed between the latch and the pole piece. The magnet is movable toward the pole piece under the influence of an electromagnetic flux generated by a pulse of current generated through the coil in one direction thereby driving the permanent magnet against the pushpin to move the valve member to one predetermined position. In addition, the permanent magnet is also movable away from the pole piece and toward the latch under the influence of an electromagnetic flux generated by a pulse of current flowing through the coil in an opposite direction. When this occurs, the biasing member moves the valve member to another predetermined position. A control circuit for changing the direction of the current through the coil is also disclosed.

摘要： A solenoid having a bobbin with a rectangular core hole in which is mounted an armature having a rectangular cross section, and a pole piece having a rectangular cross section. The bobbin has a magnet wire coil wound around a bobbin tubular body which is rectangular in cross section. The bobbin has an upper flange and a lower flange that encloses the ends of the coil. A tubular can is seated around the bobbin. A top flux plate is seated on the upper can surface and a bottom flux plate is seated under the lower can surface. The flux plates are secured to the bobbin flanges. A sealing, electrical insulating heat dissipating material is disposed inside of the tubular can which seals the coil and insulates the coil from the flux plates, tubular can and solenoid mounting screws.
