Beschreibung
Zusammenfassung:	A vacuum pump includes a housing defining a base, an internal cavity, and a partition wall defining a first chamber and a second chamber. The second chamber is sealed relative to the first chamber to form a compression chamber. A motor assembly and an electronic control unit are positioned within the first chamber. A pump assembly is positioned within the compression chamber and in communication with the lubrication fluid and the motor assembly. A battery is coupled to the housing to provide power to the motor assembly to drive the pump assembly. An inlet is coupled to the housing to connect the vacuum pump to an external system. A fluid pathway extends between the inlet and a pump inlet of the pump assembly. A valve is positioned within the fluid pathway that selectively opens and closes the fluid pathway and is biased towards a closed position.
