Reciprocating plunger pump with seal mounting support
A high pressure fuel pump has a plunger that extends through a cylinder and is reciprocally located in a pressurizing chamber. The plunger is reciprocated by a lifter and changes the volume of the pressurizing chamber to pressurize fuel in the pressurizing chamber. A seal member seals the cylinder from the lifter to prevent fuel that leaks from the pressurizing chamber from being mixed with lubricant that lubricates the lifter. A support to which the seal member is attached is formed separately from the cylinder. The support is fixed to the cylinder with the plunger extending through the support.
