Abstract
An air filter housing (10) for at least one compact air filter element (20) has at least one filter chamber (1) that at the ends has at least one hose connector socket (2, 3), respectively. The compact air filter element (20) is insertable chamber into the filter chamber between the hose connector sockets (2, 3) with sealing of the cross-section of the filter. At least one resonator chamber element (5, 6) is attached to the air filter housing (10) and is connected with the filter chamber (1) by at least one air-conducting channel (7, 8, 9) or slot.
Claims7
Air filter housing for at least one compact air filter element, comprising
- at least one filter chamber,
- an inlet hose connection socket,
- a discharge hose connection socket, said sockets arranged on axially opposing ends of said at least one filter chamber,
- a resonator chamber element arranged on and attached to an outer circumference of said at least one filter chamber and connected by an air-conducting channel or slot to said at least one filter chamber, said channel or slot extending through a filter housing wall separating said at least one filter chamber from a resonator chamber of said resonator chamber element,
- wherein the compact air filter element is insertable between the hose connector sockets with sealing of the cross-section of the filter chamber,
- wherein said filter housing includes a transition area tapering between said outer circumference of said at least one filter chamber and said axially opposing ends of said filter chamber to form said hose connection sockets,
- wherein said resonator chamber element is configured as an annular chamber element attached to said transition area and surrounding said discharge hose connection socket,
- wherein the annular chamber element is connected by an axial channel or slot extending through said housing transition area into the filter chamber.
