摘要

Device for regulating the lubricating oil pressure of an internal combustion engine comprises an oil pump (2) and an oil pressure-regulating valve (8). A chamber (30) of the oil pressure-regulating valve housing a pressure spring (18) is connected via a hydraulic line (40) to the pressure side (16) of the oil-pressure-regulating valve. Preferred Features: The rear side (10b) of a piston (10) is connected to a piston rod (22) moving in a longitudinal direction in the chamber. The pressure spring coaxially surrounds the piston rod.
