摘要

A cock structure comprises a body (2) defining on its interior a valve chamber (5) in communication with a gas bottle fitting (3) and a delivery fitting (4). In the valve chamber (5) there is translatable an actuating body (10) provided with lateral seal means (11) and a gasket (12) engageable against the opening (6) of the bottle fitting (3). The actuating body (10) is associated with a handwheel (17) engaging rotatably with threads (19) defined in the valve chamber (5). An element (21) press fitted into an annular groove (20) in the valve chamber (5) arranges itself into an annular shape to engage with a protuberance provided at the inward end of the handwheel (17) to prevent its disengagement from the body (2). At its outer end the element (21) has a head which facilitates removal of the element from the annular groove (20).
