摘要： An oil supply device for a vacuum pump of an internal combustion engine, in particular of a car, including an oil feed line via which the vacuum pump can be supplied with oil for lubricating the vacuum pump. The oil feed line includes a valve connected to the oil feed line in an oil-conducting manner, which valve has a piston that is accommodated in a valve interior of the valve and can move at least between a supply position in which it allows a supply of oil to the vacuum pump and a blocking position in which it prevents the supply of oil to the vacuum pump, and has a spring element, by means of which a spring force that holds the piston in the blocking position can be applied to the piston when the internal combustion engine is at rest.
