Embodiment Construction

[0033] figure 1 The cylinder valve 1 shown comprises a body 2 connected to an outlet orifice 3 for gas G to flow out of a cylinder 4 .

[0034] An extraction circuit C for extracting gas G is formed in the body 2 in order to connect a gas inlet 11 for gas G connected inside the cylinder 4 to at least one gas release outlet 5 , 25 . Such as figure 1 As shown, a filter 12 may be provided downstream of the inlet 11 . Downstream of the filter 12, the circuit C is divided into a plurality of pipes. The first pipe 13 communicates with a pressure gauge 14 mounted on the body 2 . The second tube 15 is connected to a filling connector 16 . A third pipe 17 or pressure relief channel conveys gas towards one or more outlets 5 , 25 . Downstream of the filter 12, the pressure relief line 17 of the circuit C comprises a safety relief valve 31 for protecting the downstream components from high pressure in the event of accidental leakage. In this way, the mechanical design described abov...

Abstract

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 (7) 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.

Description

technical field [0001] The present invention relates to a cylinder valve (robinet) for high pressure / pressurized gas cylinders. [0002] The present invention relates more particularly to such a cylinder valve for a high-pressure cylinder comprising a body for connection to the gas outlet opening of the cylinder; an extraction circuit for extracting gas comprising At least one gas outlet and at least one clack / clapet movable between a closed circuit position and an open circuit position; at least one regulating element for regulating the release flow rate of gas; and A single actuating element where both the disc and the flow rate regulating element act together. Background technique [0003] Cylinder valves for high-pressure gas cylinders are known from the prior art. Conventional such devices include a bottle valve operative to discharge gas at high pressure and a bottle valve operative to regulate the flow rate of the gas, usually expanded to low pressure, to the outlet...
