Abstract
A regulator for compressed gas, comprising a body with a gas inlet, a gas outlet and a gas passage fluidly interconnecting the gas inlet and gas outlet; a pressure reducer with, in the gas passage, a shut-off device and a movable assembly operatively connected to the shut-off device and delimiting with the body a regulating chamber downstream of the shut-off device; a pressure relief device in the gas passage downstream of the regulating chamber; and a flow restriction in the gas passage upstream of the shut-off device, dimensioned for reducing the gas pressure at the gas outlet under a maximum pressure value when the pressure relief device is opened and the shut-off device is opened.
