Abstract

A MODULAR UNIT FLUID PUMP- INJECTOR FOR PUMPING AND INJECTING FUEL INTO AN ENGINE COMBUSTION CHAMBER IS DISCLOSED AND INCLUDES A FIRST RETAINER (68) FOR SEALABLY AND REMOVABLY RETAINING THE PUMP CYLINDER (32) AGAINST THE HOUSING (18) AND A SECOND RETAINER (148) FOR SEALABLY AND REMOVABLY RETAINING AN ENCAPSULATED INJECTOR ASSEMBLY (28) AGAINST THE FIRST RETAINER (68). UNLIKE CONVENTIONAL UNIT FLUID PUMP-INJECTORS WHICH HAVE A SINGLE ELONGATED SLEEVE-TYPE NUT ENCLOSING AND CLAMPING A STACKED PLURALITY OF BOTH PUMP AND INJECTOR COMPONENTS, THE MODULAR DESIGN IS LESS PRONE TO EXCESSIVE FUEL LEAKAGE AND THE PLUNGER BINDING DURING ASSEMBLY.THE MODULAR DESIGN ALSO FACILITIES EASY ASSEMBLY OR REMOVAL OF THE ENCAPSULATED INJECTOR ASSEMBLY (28) TO OR FROM THE FIRST RETAINER (68) WITHOUT ALTERING THE POSITION OR ARRANGEMENT OF THE PUMP ELEMENTS (32, 34) RELATIVE TO THE FIRST RETAINER (68).
