A control for oil flow in a hydraulic system wherein a standard open closed type solenoid valve is modified so that the rate of flow through the valve relates to the electrical power supplied to the v

Apparatus for moving a reciprocating object, such as a spring biased poppet valve, between a rest and a second position. The apparatus includes two solenoids, each of which has a core, with one of the

A solenoid valve is mounted in the bore of a ferromagnetic journal. Mounting the solenoid valve in the journal conserves space on the firewall of a vehicle where the solenoid is typically located. Jou

A proportional solenoid valve has a casing with a receiving chamber. A valve housing is received in the receiving chamber. A solenoid with a push rod is connected to the valve housing, A piston is pos

A solenoid valve control circuit for operatively connecting a battery to a solenoid to energize the solenoid to actuate a valve includes a coulomb controlling circuit for controllably supplying electr

An improved solenoid actuated, fluid control valve includes a diaphragm which is fluid actuated. Inlet pressure through a restricted orifice into a chamber on one side of the diaphragm acts against th

A canister purge solenoid valve is constructed and arranged to provide reduced operating noise and decreased armature wear as the armature reciprocates within a bore in response to solenoid energizati

A solenoid valve of the hung diaphragm type includes a diaphragm assembly having a pilot valve seat mounted for movement toward and away from a main valve seat in a valve body, a plunger assembly cons
