摘要： The housing (5, 6) of the regulator contains a medium-pressure chamber (10) to which gas is supplied from the cylinder when a self-closing cylinder valve (2) is open and which communicates with the regulator outlet (14) through a further valve (b 13), and a low-pressure chamber (23) in open communication with the outlet. The medium-pressure chamber (10) has a diaphragm wall (15) with a spindle (16) for controlling the cylinder valve (2). The low-pressure chamber (23) has a diaphragm wall (22) for controlling the further valve (13) through a connecting rod (20) carried by the diaphragm wall and coacting at its upper end with a manual selector (21) and at its lower end with the valve opener spindle (16). By means of the selector the connecting rod may be locked in a raised position in which the cylinder valve (2) is closed.The connecting rod (20) is associated with a lockable spring mechanism (27) which is unlocked in response to a predetermined overpressure in the low-pressure chamber and which then moves the connecting rod to its raised position. This prevents a leakage of gas in case of a ruptured diaphragm or flexible tube if the further valve (13) does not close tightly when the gas consumption has been discontinued.

摘要： In a plug-and-socket coupling, particularly between a spout of a portable liquid gas container and a regulator mounted thereon, in which the first coupling part has a discharge outlet adapted to receive a stud or protrusion of the second coupling part, leakage to the surroundings from a pressure fluid passage through the coupling is impeded by an annular gasket movably disposed within an annular chamber between the stud and a surrounding skirt. Between the gasket and the stud there is a passge for pressure fluid to the annular chamber behind the gasket for loading the gasket to closely but against the internal surface of the skirt and a surface on the first coupling part.
