ABSTRACT:
A compressed natural gas solenoid controlled valve is mounted in the threaded opening of a pressure vessel which contains the gas. The valve includes a valve body having a head which is exposed outside of the pressure vessel and a neck which is located within the pressure vessel. A solenoid poppet valve is mounted to the inner end of the neck. A valve seat is mounted in a bore within the valve body, and provides a flow passage which extends between an orifice at the inner end of the valve seat and an outlet port which is located in the head of the valve body. The solenoid poppet valve includes a seal for closing the orifice, a bias spring which biases the seal toward the seat to close the orifice, a plunger which is connected to the seal, and a solenoid coil which, when energized, moves the plunger so that the seal moves out of engagement with the seat and permits flow of compressed gas from the interior of the pressure vessel to the outlet port.
