A filter element arranged in the filter housing separates the inlet seal-tightly from the outlet. A releasable anchoring device connects the housing parts. The anchoring device has a rotary insert having a guide and anchoring section and an interacting receptacle with an insertion/removal section. The rotary insert of the first housing part is arranged in the receptacle of the second housing part. The guide and anchoring section has a first rotary state in which it is positively guided for gliding in the insertion/removal section to guide the housing parts when being connected or separated. In a second rotary state the guiding and anchoring section is secured in an anchoring section of the receptacle for securing the housing parts. The insertion/removal section passes into the anchoring section.Type: GrantFiled: February 1, 2010Date of Patent: October 9, 2012Assignee: Mann+Hummel GmbHInventors: Stefan Walz, Juergen Kosicki, Joachim Streich, Markus Hanselmann, Thomas Jessberger

Patent number: 8273145Abstract: A filter holder assembly includes at least one frame having a peripheral wall and an inwardly directed peripheral edge substantially perpendicular to said peripheral wall and adapted to support a filter. At least one cam lock lever is secured to the peripheral wall at a first predetermined distance from the inwardly directed peripheral edge for compressing the filter in the frame and against said inwardly directed peripheral edge. The cam lock lever has a handle portion at one end thereof and a cam head provided with a cam foot at an opposite end thereof. The cam lock lever is rotatable to cause the cam foot to move between an open position and clamping position where the cam foot exerts a compressive force on the filter.Type: GrantFiled: September 13, 2010Date of Patent: September 25, 2012Assignee: General Electric CompanyInventors: Stephen Francis Banks, Peter McGuigan
