Patent attributes
A gas valve assembly includes a solenoid coil, a linearly actuated plunger, and a stop member. The plunger is disposed in the coil so that a gap exists between the plunger and the stop member at a deenergized condition of the solenoid. The assembly includes a valve having a port and a closing member. The closing member blocks the port in a closed position corresponding to the de-energized condition of the solenoid, and slidably unblocks the port in an open position corresponding to the energized condition of the solenoid. An adjustable length member is coupled to the closing member and the plunger and has a portion accessible external to the valve assembly. The externally-accessible portion of the adjustable length member is adjustable to vary the size of the gap between the plunger and the stop member when the closing member is in the closed position.
