초록

A sealed solenoid provides an improved actuator for valves and other devices, particular such devices used in extreme environments and/or with corrosive media. For example, the improved solenoid construction can be used to drive a precision flow control valve used in air and space applications, such as to control fuel and oxidizer combustion media in rocket and other thrust components. The solenoid is retained in a solenoid retainer to which is attached a rigid barrier that isolates the solenoid pole piece and coil from the media. A clapper disposed outs...

1. A solenoid actuator for a valve having a valve member movable within a housing to control the flow of a working media through an interior of the housing from an inlet port to an outlet port, the actuator comprising: a wire coil and at least one pole piece made of a magnetically active material;a solenoid retainer configured to couple to the housing and defining an interior space containing the wire coil and the at least one pole piece;a magnetically inert barrier member forming a closed end of the solenoid retainer; anda magnetically active armature s...
