VALVE UNIT OF A FUEL FEEDING SYSTEM, CAPABLE OF REDUCING ABRASION

摘要

PURPOSE: A valve unit of a fuel feeding system is provided to reduce abrasion, since the tempering temperature of separate insert steel is higher than the tempering temperature of the steel of a base body.;CONSTITUTION: In a valve unit of a fuel feeding system, a constant pressure relief valve(15) is formed in a base body(11) made of steel. The constant pressure relief valve comprises an actuation member(20) receiving load with a spring member. The actuation member comprises a valve sheet(24) of a constant pressure relief valve. The valve sheet of the constant pressure relief valve is formed by a separate insert(25) made of steel.;COPYRIGHT KIPO 2011
