Abstract:
A vent valve for a gas strut comprising:a body which, in use, sealingly closes an end of the cylinder of a gas strut;a valve seat defined in the body;a first passage in the body extending from one side of the valve seat to a surface of the body which, in use, is exposed to the interior of the gas strut;a second passage in the body extending from the other side of the valve seat to a surface of the body which, in use, is exposed to the exterior of the gas strut, the second passage being screw-threaded;a screw in screw-threaded engagement with the screw threads of the second passage; anda ball located between the screw and the valve seat whereby tightening of the screw will force the ball into engagement with the valve seat to prevent the flow of the gas from the first passage to the second passage,wherein clearance between mating threads of the screw and the second passage provides the sole path for fluid passing through the valve.
