ABSTRACT:
A pressure regulating valve for venting the crankcase of an internal combustion engine in which the pressure regulating valve is combined with a motor oil filler tube and with an oil dip stick. This combination is distinguished by the fact that it is especially compact, and centrally connects all of the components relating to oil supply and monitoring in an internal combustion engine. This combination is further characterized in that only one connecting opening is needed on the engine block for adding oil, for returning oil from the pressure regulating valve to the oil pan, and for accommodating the oil dip stick.
