Crash proof solenoid controlled valve with manual override valve

A valve for controlling flow of compressed gas from a pressure vessel, the valve comprising:

• a head having an outlet port;
• a neck connected to the head and having external threads for engagement with the pressure vessel, having an inner end, and having a bore which extends between the inner end and the head;
• a first valve seat having an orifice in communication with the bore;
• a flow passage extending between the orifice and the outlet port;
• and
• a solenoid valve connected to the inner end of the neck, the solenoid valve including a first seal for closing the orifice, means for biasing the first seal toward the seat to close the orifice, a plunger connected to the first seal, and a solenoid coil for moving the plunger so that the first seal moves out of engagement with the orifice.

A system for supplying a controlled flow of compressed gas, the system comprising:

• a pressure vessel having an interior for containing the compressed gas and having a threaded opening;
• a valve body having a head with an outlet port and having a neck with external threads, the neck being inserted into and connected to the threaded opening in the pressure vessel;
• a first valve seat, within the valve body, having an orifice;
• a flow passage leading from the orifice to the outlet port;
• a first seal movable within the valve body for closing the orifice;
• means for biasing the first seal toward the first valve seat;
• and
• a solenoid mounted to the neck and positioned within the interior of the pressure vessel for moving the first seal away from the first valve seat in response to an electrical control signal.

A valve for controlling flow of compressed gas from a pressure vessel, the valve comprising:

• a valve body having a head and a neck, the head having a first port and a second port, the neck having an inner end for positioning within the pressure vessel and a bore extending from the inner end to the head, the bore communicating between an interior of the pressure vessel and the first and second ports, wherein the neck is configured to be connected to the pressure vessel;
• a valve seat positioned in the bore and connected to the valve body, the valve seat having a first end, a second end and a flow passage extending between the first and second end, the first end in communication with the first port;
• a solenoid valve mounted to the inner end of the neck, the solenoid valve including sealing means for closing the second end of the valve seat, and a solenoid coil for actuating the sealing means to open the second end of the valve seat;
• and
• valve means between the second port and the interior of the pressure vessel for sealing the second port when the valve means is in a first position, and for exposing a flow path in the bore between the second port and the pressure vessel when the valve means is in a second position.
