Patent number: 10617981Abstract: A filter device for fluids, in particular in the form of a tank-installation return filter, includes a filter element (27) accommodated in a housing (3) having a fluid inlet (17) for supplying unfiltered fluid to an inner cavity (31) of the filter element (27). The inner cavity is surrounded by a filter medium (29) through which unfiltered fluid can flow. A flow-conducting apparatus (13, 49, 77) orients the flow of the unfiltered fluid reaching the filter medium (29) and is provided between the fluid inlet (17) and the inner cavity (31) of the filter element (27).Type: GrantFiled: July 5, 2014Date of Patent: April 14, 2020Assignee: RT-FILTERTECHNIK GMBHInventors: Marco Bautz, Gerhard Stehle

Patent number: 10421031Abstract: 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.Type: GrantFiled: June 26, 2014Date of Patent: September 24, 2019Assignee: RT-FILTERTECHNIK GMBHInventors: Gerhard Stehle, Marco Bautz

Patent number: 10406457Abstract: A filter device has a support part (39, 43) receiving a filter part (1), a sealing device (17) acting between the support part (39, 43) and the filter part (1), and a securing device (53, 57, 61) releasably connecting the support part (43) to the filter part (1). The securing device has a circumferential collar part (53) that, under the action of an energy store (61), exerts a force on the sealing device (17). That force seals the support part (39, 43) and the filter part (1) in a fluid-tight manner with respect to one another. The support part (39, 43) has, on its end region oriented toward the securing device (53, 57, 61), another circumferential collar part (39). The collar part (53) of the securing device (53, 57, 61) is guided concentrically within the collar part (39) of the support part (39, 43) provided with a sealing system (41, 72).Type: GrantFiled: April 19, 2016Date of Patent: September 10, 2019Assignee: RT-FILTERTECHNIK GMBHInventors: Marco Bautz, Gerhard Stehle
