ABSTRACT:
A fluid control valve includes an axially slidable valve member which is coupled directly to the armature of an electromagnetic actuator by a valve stem. The valve member has a head which is drawn into contact with a seating when the device is energized. In this position a step defined between the valve member and the stem is exposed beyond the body containing the valve member. The step is engaged by a spring abutment collar slidable on the stem and engaged by a return spring which biases the valve open and an anti bounce spring. The opposite end of the spring is connected to the stem and the spring is compressed during movement of the valve member and armature to the open position after the collar has engaged the body. The spring then returns the valve member to its normal open position.
