  • Patent number: 8757393
    Abstract: A replaceable filter has a filter housing with a cylindrical connecting end. A housing lid has a cylindrical counter connecting member matching the cylindrical connecting end. A filter closure system seal-tightly connects by form fit the cylindrical connecting end and the cylindrical counter connecting member when the connecting end is inserted or pushed onto the counter connecting member in an axial connecting direction and moved relative to the counter connecting member. An annular member is arranged coaxially relative to the connecting end and has a terminal edge area that is connected seal-tightly to the filter housing such that the annular member and the connecting end define a receptacle for the cylindrical counter connecting member. A sealing device is arranged in the receptacle and connected to the filter housing. The sealing device interacts with the counter connecting member.

  • Patent number: 8613786
    Abstract: A fluid filter includes a base plate, a canister, and filtering media contained in the canister for filtering fluid from an inlet port to an outlet port. Notches are formed into an outer periphery of the base plate. An annular bead of the canister side wall is partially formed into the notches to provide a torque locking mechanism between the base plate and the canister. The terminating lip portion of the canister is wrapped around the outer face of the base plate and formed into an annular trough to directly secure the base plate to the canister. The annular trough includes a diverging outer wall that provides a narrow contact interface between the terminating lip portion and the retention corner of the base plate to thereby reduce moment loads induced therebetween as a result of high fluid pressures in the filter.
