The invention relates to a device for at least intermittently generating an overpressure in a system S in relation to an ambient pressure U, with a pump P that has a pressure side 20 and an intake side 10, where during the generation of an overpressure, the pressure side 20 is connected to the system S and the intake side 10 is connected to the ambient pressure by means of at least one first valve MV1, in particular a solenoid valve. According to the invention, means are provided, which can provide an additional cross section for the intake volume flow during the generation of an overpressure. The invention also relates to a valve, which is particularly provided for use with the device according to the invention.
