Abstract (en)
During the operation of a high pressure fuel pump, it is normal to expect internal fuel leakage between a pumping plunger (30') and plunger bore (28'). Current pump designs position critical interfaces (55', 59') directly in-line with the leaking fuel. A fuel deflector surface (58') may be used to re-direct the flow of hot, leaking fuel away from the critical interfaces (55', 59') and toward a lower cam box (51') where the fuel may be cooled with other resident fuel. The deflector surface (58') may be shaped and vents (52') positioned to channel (B) the hot fuel to flow toward a lower cam box (51').
