ABSTRACT:
The present invention relates to an oil pump of the forced lubrication system in an automobile engine. The oil pump is mounted in the lower crank case, preferably at the bottom of the oil pan in order to be immersed in a lubricating oil filled therein. The oil pump of the present invention is a combination of the well known plunger type oil pump and the swash-plate pump, which has two pistons and one T-shaped operating rod incorporated therein. The outer end of the T-shaped operating rod is extended to the engine crank shaft. The outer end of the operating rod is directly coupled to the bearing load of the crank shaft, opposite to the engine connecting rod, to form a second connecting rod which allows translation of the connecting rod from rotation of the crank shaft.
