HIGH PRESSURE FUEL PUMP FOR DIRECT INJECTING GASOLINE ENGINE WHICH CAN INSPECT PERFORMANCE BEFORE ASSEMBLING TO A HIGH PRESSURE FUEL PUMP

摘要

PURPOSE: A high pressure fuel pump for direct injecting gasoline engine is provided to prevent the rotation of an output module and to improve assemblity by preventing errors on construction.;CONSTITUTION: A high pressure fuel pump for direct injecting gasoline engine comprises a body(10), a bracket(20), a damper part(30), a spill valve(40), an inlet check valve(50), and a discharging module(60). The inlet check valve is combined in the inlet port and is connected to a spill valve. The discharging module comprises a discharge side check valve and a pressure relief valve. The discharge side check valve discharges the fuel compacted with an intake member. The high pressure is generated in the pressure relief valve, when the discharge pressure of the fuel discharged through a check valve exceeds a fixed limiting pressure.;COPYRIGHT KIPO 2012
