TAP FOR PRESSURISED GAS CYLINDER

摘要

The invention relates to a tap (1) for a pressurised gas cylinder, that comprises a body (2) to be connected to a gas (G) outlet opening (3) of a gas cylinder (4), un gas (G) off-take circuit (C) including at least one gas outlet (5, 25), at least one valve (6) movable between a circuit (C) closing position and a circuit (C) opening position, at least one member (23) for adjusting the release flow of the gas (G), and a single actuation member (9) capable of interaction both with the valve (6) and with the flow adjustment member (23), characterised in that the actuation member (9) is mounted so as to be movable relative to the body (2) according to two distinct movements, said actuation member (9) being arranged relative to the valve (6) and the flow adjustment member (23) so that the two types of movements respectively control the movement of the valve (6) between the opening and closing positions on the one hand and the flow adjustment member (23) on the other hand. The invention can be used as a tap with a built-in expander for a pressurised gas cylinder, e.g. pressurised oxygen in particular for oxygen therapy in medicine.
