摘要：This invention relates to combustion units in which combustible fluids are fed toa combustion chamber and burnt, and in which the resulting combustion gases are usedto drive a power output. The combustion unit includes a combustion chamber; means forigniting combustion fluids in the combustion chamber; power output means drivable bythe resulting combustion gases; a compressor for supplying air to the combustionchamber; and a gas supply including a control valve for supplying fuel gas to thecombustion chamber for burning in the air, the control valve having

a control chamber,

an outlet member extending into the control chamber,

an outlet passage in the outlet member and defining an outlet from the controlchamber, said passage communicating with the combustion chamber to supply fuel gasto the combustion chamber,

an inlet for supplying fuel gas into the control chamber and capable ofcommunicating with the outlet,

a valve seat in the control chamber and surrounding the inlet, and

a shuttle piston movable along the outlet member, the shuttle piston having aclosure surface for engaging the valve seat to close the inlet,

wherein fuel gas flowing into the inlet holds the closure surface away from the valveseat and thus flows through the control chamber to the outlet and to the combustionchamber until combustion gases in the combustion chamber create a back-flow to theoutlet at a pressure sufficiently in excess of the pressure at the inlet to move the closuresurface towards the valve seat and to close the inlet.
