Pressure regulation valve for a motor vehicle combustion engine crankcase has its components and connection to the crankcase aligned to minimize pressure loss and maximize the pressure differential over the oil mist separator

摘要

Pressure regulation valve for adjustment of the vacuum pressure in the crankcase (2) of a combustion engine (1). Said valve has a housing that connects it to the pressure chamber (28) via a pressure connection (17). Said pressure connection, valve seat and vacuum pressure connection are arranged in a straight line relative to the longitudinal axis of the valve housing.
