    摘要： The invention is directed to a gas pressure reducer (2) comprising a body (10) with an inlet (4) intended to be in flow communication with a high pressure gas source; an outlet (6) intended to deliver the gas at a predetermined low pressure; a passage (8) through the body (10) in flow communication with the inlet (4) and with the outlet (6). A resilient element (24) engages with a pressure reducing piston (18) with a through flow path (22) formed by a needle (20). The needle (20) cooperates with a movable seat (16). The outlet pressure acts on the piston (18) in opposite direction than the spring (24) so as to urge the path (22) against the seat (16) in order to reduce the gas flow through the path (22). Pressure setting means comprise an electric actuator (32), such as a stepper motor, which moves the seat (16) along the moving direction of the piston (18) in order to set the predetermined outlet pressure.

    摘要： A device for regulating the pressure and/or flow of pressurized gas, comprising a body with a gas inlet, a gas outlet and a gas passage connecting the outlet with the inlet, a pressure reducer and a flow selector arranged downstream of the pressure reducer, a hand-wheel rotatably mounted on the body and cooperating with the flow selector for adjusting the flow, and a pressure indicator located at the center of the hand-wheel. The device comprises also a shaft rigidly fixed to the body and rotatably bearing the hand-wheel, the shaft supporting the pressure reducer and comprising a gas channel fluidly connected to the gas passage in the body.

    摘要： The invention is directed to a device (2) for regulating the pressure and/or flow of pressurized gas, comprising a body (4) with a gas inlet (6), a gas outlet (8) and a gas passage (10, 26) connecting the outlet (8) with the inlet (6), a gas shut-off device comprising a seat (22) in the passage (10) and a movable closure element (24) cooperating with said seat (22) and a piston (12) carrying the closure element (24) and delimiting with the body (4) a low pressure chamber (28) downstream of the shut-off device (22, 24). The body (4) comprises a first portion (41) with the seat (22) and the inlet (6) and a second portion (42) housing the piston (12) and delimiting the low pressure chamber (28). The second portion (42) is movable relative to the first portion (41) between a closed position, and an open position.
