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.

Patent number: 11725663Abstract: A rotary piston pump, in particular a claw pump, includes a housing which, when placed in a customary manner, has a housing inlet in a housing upper side. In order to further improve a rotary piston pump in a beneficial way, the housing inlet is connected to a gas channel that is integrated in the housing and extends transversely to a rotational axis of the piston, which gas channel creates a flow connection to a gas outlet of a filter part arranged in a filter receptacle. In the installed state, the filter part is accessible from a side perpendicular to the housing upper side, for maintenance purposes, for example.Type: GrantFiled: February 3, 2020Date of Patent: August 15, 2023Assignee: Gebr.

Publication number: 20220362691Abstract: The invention relates to a method for intermittently cleaning a filter in a filter device, which filter device comprises a filter housing and the filter located therein. The filter housing has a medium inlet and a medium outlet for a medium to be filtered. During filter operation, the medium flowing through the medium inlet passes through the filter and exits the filter device via the medium outlet. In order to clean the filter, both the medium inlet and the medium outlet are closed and a negative pressure is produced in the filter housing and a flushing medium is sucked into the filter housing by the negative pressure.Type: ApplicationFiled: November 17, 2020Publication date: November 17, 2022Applicant: Gebr.

Publication number: 20210394241Abstract: A method for operating a metal printing device has an enclosure in which the metal printing is carried out, the enclosure having an inlet and an outlet, and a fan also being provided, with which the atmosphere in the enclosure can be regenerated, a device also being provided in order to be able to extract particles in particular after a printing process is complete. In a first method step, process gas is extracted from the enclosure and conducted through a regeneration device in order to clean the atmosphere in the enclosure. In a second method step after the printing process is complete, excess particles are removed from the enclosure. A suction fan having a suction line connection is provided, wherein the mode can be switched over using a switchover device connected upstream of the suction fan.Type: ApplicationFiled: November 6, 2019Publication date: December 23, 2021Applicant: Gebr.

Patent number: 10697298Abstract: An oil-lubricated slide vane rotary vacuum pump with a slide vane unit, and with an oil separating and reconditioning device, wherein oil and gas are separated by separating devices, possibly complemented by oil coolers and/or oil pumps. One or more monitoring and/or servicing devices are provided, and the oil separating and reconditioning device is installed in an oil separating and reconditioning housing. Side walls extend transversely to a plane of rotation of a slide vane rotor, and define a longitudinal extent of the oil separating and reconditioning housing. The one or more monitoring and/or servicing devices are arranged only in one or more cover parts which are attached to one or both end walls of the oil separating and reconditioning housing. The oil separating and reconditioning housing is formed with the side walls, the bottom wall and the top wall without being configured for a monitoring and/or servicing device.Type: GrantFiled: May 17, 2016Date of Patent: June 30, 2020Assignee: 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.
