Abstract
A number of embodiments of high pressure pumps for internal combustion engines having vertically extending output shafts. In each embodiment, the high pressure pump has its pump driving shaft rotatable about an axis that is parallel to the crankshaft axis and is driven by the crankshaft. This arrangement lends itself to application in outboard motors. The high pressure pump includes an integral lubricating pump for lubricating components of the high pressure pump.
Claims33
A fuel injected internal combustion engine having an output shaft rotatable about a vertically extending output shaft axis and driven by the combustion within the engine, a high pressure piston pump driven by a rotatable pump driving shaft journaled for rotation about a vertically extending pump drive axis and extending parallel to said engine output shaft axis, pump drive means for driving said pump drive shaft from said engine output shaft, and a lubricant pump driven off one end of said pump drive shaft for pumping lubricant to the elements of said high pressure pump.
