HIGH PRESURE FUEL PUMP FOR DIRECT INJECTION TYPE GASOLINE ENGINE

摘要

PURPOSE: A high pressure fuel pump for direct injecting gasoline engine is provided to prevent that gasoline fuel evaporates with the heat delivered from engine oil. 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), a discharge side check valve(60), and a circulation flow path. The damper part reduces the pulsating of the fuel which is combined in the joint of the body. The spill valve controls the supply flux and discharge pressure of the fuel while being combined in the inlet port. The inlet check valve t is combined in the inlet port and is connected to the spill valve. The discharge side check valve is combined in a discharge side aperture. The circulation flow path is formed in the body.
