    • PURPOSE: A cavitation damage prevention apparatus of a diesel engine fuel injection pump is provided to prevent cavitation generated before or after the opening of a barrel port at the late stage of fuel compression by employing a constant pressure valve installed in a deflector or barrel of a fuel injection pump. CONSTITUTION: A cavitation damage prevention apparatus of a diesel engine fuel injection pump comprises a constant pressure valve(110) including a valve member(111) which shuts a barrel port(104) to raise the internal pressure at the initial state of fuel compression by an upward motion of a plunger(103), a valve housing(112) which is installed in a deflector(106) or a barrel(102) of a pump housing(101) to support the valve member, and a spring(113) which is installed between the valve member and the valve housing to support the valve member. The constant pressure valve opens the barrel port when the internal fuel pressure of the barrel port exceeds an opening pressure.
