Title:
COMBUSTION UNIT
Document Type and Number:
Japanese Patent JPS5484116
Kind Code:
A
Abstract:
This invention relates to combustion units in which combustible fluids are fed to a combustion chamber and burnt, and in which the resulting combustion gases are used to drive a power output. The combustion unit includes a combustion chamber; means for igniting combustion fluids in the combustion chamber; power output means drivable by the resulting combustion gases; a compressor for supplying air to the combustion chamber; and a gas supply including a control valve for supplying fuel gas to the combustion 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 control chamber, said passage communicating with the combustion chamber to supply fuel gas to the combustion chamber, an inlet for supplying fuel gas into the control chamber and capable of communicating 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 a closure surface for engaging the valve seat to close the inlet, wherein fuel gas flowing into the inlet holds the closure surface away from the valve seat and thus flows through the control chamber to the outlet and to the combustion chamber until combustion gases in the combustion chamber create a back-flow to the outlet at a pressure sufficiently in excess of the pressure at the inlet to move the closure surface towards the valve seat and to close the inlet.
