Abstract
A valve assembly comprising a movable valve member which is urged resiliently toward a valve seat and which is actuated by a connecting rod. In order to ensure that the connecting rod does not become accidentally disengaged from the movable valve member, but is nevertheless releasable therefrom, the connecting rod is arranged to be received in a pocket in the movable valve member, which pocket is closed by a slotted plate. The slot allows the end of the connecting rod to be inserted into the pocket in one relative angular position while preventing it from being removed when in any other angular position. The end of the connecting rod is T-shaped and is rotated 90.degree. after being passed through the slot. The pocket has a groove which receives the head of the T-shaped end to prevent relative rotation of the valve member in use. The connecting rod is operated by way of a crank which goes over center when the valve is fully open.
