ABSTRACT:
A solenoid operated valve is disclosed having a valve housing including a passage therethrough, a valve seat within the passage, and a valve member movable between an open and a closed position. A solenoid actuator is provided for effecting movement of the valve member. The solenoid includes a coil selectively energizable and de-energizable by a source of electric power for generating a magnetic flux. A tube is provided having a closed outer end and an open inner end disposed generally coaxially with respect to the coil, and with the inner end of the tube being secured to the valve housing. The tube receives the valve member as it moves axially within the tube between its open and closed positions. A housing receives the coil and the housing has an outer face with an opening therein such that with the housing and the coil receiving the tube, the outer end of the tube extends out beyond the outer face of the housing. Specifically, the tube has a circumferential groove therearound adjacent its outer end and the groove is spaced beyond the outer face of the housing. A fastener, such as a spring clip, is provided which is secured to the housing and is carried on the outer face of the housing so as to resiliently cooperate with the groove on the tube as the housing and the coil are installed on the tube so as to secure the housing and the coil relative to the tube.
