Abstract
A hydraulic pump in the form of an oil pump for a vehicle engine has both its pinion, which is driven by the engine's crankshaft, and a ring-gear, which cooperates with the pinion, incorporated in an end-cover fastened to the end of the engine block. A cap is inserted in a collar on the side of the end-cover facing away from the engine and is only held in position there by means of a locking ring, which engages with a groove in the collar and presses the cap toward the engine. Outside the oil pump, a partly socket-shaped belt pulley is mounted on the crankshaft and its socket-shaped portion substantially grips the collar. Fitting and removal are thus simplified and engine overall length reduced. Simplified sealing also reduces oil leakage risks.
