Patent number: 11767845Abstract: An oil-lubricated rotary vane vacuum pump includes a rotary vane unit, having a rotary vane chamber and a rotary vane rotor, and an oil separator device having an air/oil separating unit that has a filter element with a plug-in ring that can be plug-connected on a housing side. The plug-in ring is designed for radial sealing and axial displaceability in a housing receptacle. The filter element has a moulding for bayonet mounting, which faces the end associated with the outer wall. A mounting wall of the housing, extending at a distance from the outer wall of the housing, is designed to interact with the moulding of the filter element and to form the bayonet mounting. A separate cover closes a mounting opening associated with the filter element in the outer wall of the housing. The cover form-fittingly interacts with the filter element to secure the filter element against rotation.Type: GrantFiled: March 4, 2020Date of Patent: September 26, 2023Assignee: Gebr.
