Abstract
A vent valve for a gas strut includes a first passage (9,12) in a body (2) extending from one side of a valve seat (8) to a surface of the body (2) which, in use, is exposed to the interior of a gas strut, and a second passage (15) in the body (2) extending from the other side of the valve seat (8) to a body surface which, in use, is exposed to the exterior of the gas strut. A ball (18) is provided between a screw (17), threadedly engaged with the second passage (15), and the valve seat (8), whereby tightening of the screw (17) forces the ball (18) into engagement with the valve seat (8). A controlled release of gas through the vent valve is thereby possible.
