Patent ID: 10421031

Abstract:
A filter device has at least one filter element (17, 19) exchangeably received in a housing (9). The filter element has a filter medium (23) permeable to a flow of the fluid to be purified and has, on at least one end, an end cap (25) that, for the purpose of positioning of the filter element (17, 19) in a functional position, interacts with a fixing body (33) connected to a removable cover (11) of the housing (9). A bypass valve (51) is provided on the fixing body (33). On the fixing body (33), a wall part (57) in the functional position forms a dividing element in the housing separating the housing into a filter element chamber (65) and a bypass chamber (63) situated at the outflow side of the bypass valve (51). The bypass chamber has a protective filter (67) through which the fluid flowing out of the bypass valve (51) can flow.
