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. Becker GmbHInventors: Artjom Kraft, Ulli Kriebel, Bernhard Radermacher, Carsten Bender, Carsten Posser

Patent number: 10378543Abstract: The invention relates to an impeller (1), in particular for a side channel machine, comprising blades (5) arranged distributed in the circumferential direction and formed in each case by a blade wall (6), which blades form open blade chambers (4) in a plan view onto the impeller (1), wherein a blade wall (6) in the plan view starts at a first radius dimension (r1) related to the geometrical impeller rotation axis (x), which first radius dimension (r1) corresponds to half or more than half of a second radius dimension (r2), which second radius dimension (r2) defines a circumferential rim edge (9) of the impeller (1), and wherein the radius dimension (r1) defines a radially inner boundary wall (7) of the blade chamber (4), wherein furthermore a blade wall (6) comprises an exposed upper terminating edge, which runs correspondingly radially on the inside into the inner boundary wall (7) and ends radially on the outside in plan view, wherein an imaginary connecting line (V) can be drawn between a run-in point of tType: GrantFiled: March 19, 2015Date of Patent: August 13, 2019Assignee: Gebr.

Patent number: 9675921Abstract: The invention first relates to an air filter attachment (4) for a turbomachine, in particular a side channel compressor, comprising a housing, comprising a filter material (8) arranged in a housing interior, and comprising an inlet (9) and an outlet (10) which are formed in the housing, which have a free opening cross section, and through which air is suctioned. The aim of the invention is to advantageously design a turbomachine comprising an air filter attachment. This is achieved in that the housing interior that has the filter material (8) extends laterally relative to the opening cross section of the inlet (9) and/or the outlet (10) in a non-uniform manner and in any case in a direction by a magnitude of 1½ or more times the dimension from a central axis (M) of the respective opening cross section to a periphery of the opening cross section in the direction. The invention further relates to a turbomachine, in particular a side channel compressor, comprising such an air filter attachment.Type: GrantFiled: July 11, 2012Date of Patent: June 13, 2017Assignee: Gebr. Becker GmbHInventors: Rudolf Bahnen, Ulli Kriebel, Lars Buchholz, Henryk Waniek, Achim Von Kathen
