Abstract
An elongated sleeve, externally threaded, is threadedly engaged with threaded bores in transverse walls formed in a straight cylinder of a gas compressor. A nut is secured to an intermediate portion of the sleeve, by means of a setscrew, and an end of the sleeve threadedly mounts a valve. The cylinder wall has an aperture formed therein to provide access for an open-end wrench, so that the wrench can work the nut to cause rotation of the nut and the sleeve, and move the valve outwardly or inwardly of the cylinder, as the valve is wholly confined within the cylinder at the frame-end thereof, and is otherwise inaccessible for movement.
