Patent number: 7985273Abstract: A device for the precipitation of liquid from a gas stream includes a preseparator chamber in a first housing portion arranged to flow a gas stream laterally centrally to rebound from an opposing sidewall and deflect upwards to a main separator in a second housing portion. The main separator includes a drainage element separating oil from the gas stream. A guide element is arranged between the housing portions and includes an outer wall with a central opening and at least one guide part arranged on the wall to laterally deflect the gas stream. The deflected gas stream flows laterally through the main separator.Type: GrantFiled: October 20, 2008Date of Patent: July 26, 2011Assignee: Mann + Hummel GmbHInventor: Wolfgang Heikamp

Publication number: 20100242422Abstract: A device for the precipitation of liquid droplets from a gas stream having the following characteristics is proposed: a pre-precipitation chamber (4) is provided, into which the gas stream to be purified is conducted such that it rebounds on a wall (6) of said pre-precipitation chamber (4) and is conducted vertically upward (arrow 7) by the flow pressure in the wall area. A main precipitator (3), which is disposed vertically above said pre-precipitator (4), is provided, comprising a drainage element, which can have the gas stream to be purified flow through it laterally from the outside to the inside (arrows 13) and centrally releases the purified gas stream vertically upward (arrow 14).Type: ApplicationFiled: October 20, 2008Publication date: September 30, 2010Applicant: MANN+HUMMEL GMBHInventor: Wolfgang Heikamp

Patent number: 7588615Abstract: A filter element for separating a liquid from a gas stream, e.g. for de-oiling compressed air produced by an oil lubricated compressor, including an annularly closed filter medium and upper and lower end disks at the axial end faces of the annular filter medium, in which the lower end disk closes off an interior space formed by the filter medium, and a drainage tube extends into the interior space and is guided at the upper end disk by a preferably conical sealing element mounted on a support plate on the upper end disk such that when the filter element is installed in a container, the sealing element fits against and forms a seal with a cover of the container. The sealing element optionally has a hollow interior to facilitate compensation of tolerances in at least one of the x-direction and the y-direction.Type: GrantFiled: February 28, 2006Date of Patent: September 15, 2009Assignee: Mann & Hummel GmbHInventors: Eric Gillenberg, Wolfgang Heikamp, Melanie Hirsch, Otto Eppel, Sandra Poelloth, Hans-Michael Winter
