APPARATUS FOR COMPENSATING PRESSURE AND FLOW FLUCTUATIONS IN FUEL SUPPLY SYSTEMS FOR GAS TURBINES

摘要

A device for compensating variations in pressure and flow in fuel supply systems of gas-turbine engines comprising a pump for supply of fuel under pressure into a fuel line and an accumulator which can be connected to the fuel line as a function of operating conditions. An accumulator disconnection valve relieves the accumulator from existing variations in pressure in the supply system and serves as a shutoff valve controlled by pressure differential between the fuel line and the accumulator. The valve comprises two valve members which are connected opposite each other and are spring-loaded in directions opposite each other.
