ABSTRACT:
The supply fitting for gas cylinder valves, particularly of acetylene cylinders, consists of a housing provided with a supply inlet and a portion for engaging and retaining a gas cylinder vlave, which portion is formed with a supply outlet, a piston sleeve, which is movably mounted and sealed in the housing and displaceable against the force of a spring and comprises a valve member, which is formed with a through passage and is biased by a spring to its sealing position and is adapted to open a supply passage through the housing after the supply fitting has been attached to a gas cylinder valve, and means for holding the piston sleeve in position before and after the supply fitting has been attached to a gas cylinder valve. In a preferred embodiment the means for holding the piston sleeve in position comprise an eccentric actuating mechanism with associated detent means for preventing an inadvertent adjustment. The supply fitting can reliably and safely be handled also by unskilled persons.
