Abstract
A pressure control valve for controlling the vacuum in a crankcase housing, which valve is disposed on an oil filler opening (33) and simultaneously acts as a cap for the oil filler opening. A tube 37 through which the crankcase gases are conveyed to the air intake of the internal combustion engine is provided in the oil filler opening. The pressure control valve serves to establish a certain vacuum in the crankcase, is of compact construction, and can be replaced or checked in a simple manner.
