Abstract
A tap for a pressurized gas cylinder that includes a body with a gas inlet, a gas outlet, a gas passage connecting the inlet to the outlet, a device for maintaining residual pressure arranged on the gas passage, and a shut-off valve for closing the gas passage, downstream from the device for maintaining residual pressure. A wheel for controlling the tap acts on the shut-off valve and on the device for maintaining residual pressure via control rods. The wheel comprises sliding tracks for the control rods and a first position for filling the cylinder wherein the device for maintaining residual pressure is deactivated and the shut-off valve is open, a second position for closing the cylinder wherein the device for maintaining residual pressure is activated and the shut-off valve is closed, and a third position wherein the device for maintaining residual pressure is activated and the shut-off valve is open.
