Abstract
An electromagnetic fluid pump having a generally cylindrical housing divided into an inlet chamber, an outlet chamber and an intermediate chamber by a pole member and a separator plate. The pole member is sealingly attached to the wall of the housing and divides the inlet chamber from the intermediate chamber. A first O ring provides a gas tight seal between the pole member and a piston guide which provides a fluid passageway between the inlet chamber and the outlet chamber. The separator plate is sealingly attached to the end of the piston guide adjacent to the outlet chamber and separates the outlet chamber from the intermediate chamber. A second O ring provides a gas tight seal between the internal wall of the housing and a rim portion of the separator plate. An electrical connector having a connector pin provides electrical power to an electronic circuit periodically energizing a solenoid coil to reciprocate a piston disposed in the piston guide. A third O ring provides a gas tight seal between the connector pin and the body of the electrical connector. One-way valve means provide for unidirectional fluid flow from the inlet chamber to the outlet chamber in response to reciprocation of the piston in the piston guide.
