Abstract
A water filter cartridge has an end cap with inlet and outlet nozzles extending from the end cap. A lateral support extends laterally from at least one of the nozzles. A projection extends from the lateral support toward a receiving manifold to cooperate with the manifold during use. The lateral support is offset from the end cap so the projection is vertically offset from an end of the cartridge and laterally offset from and supported from the nozzles.
Claims22
A water filer cartridge having a first end, a closed second end, and a cartridge longitudinal axis extending through the ends, the cartridge having a filter media contained within the housing between the first and second ends, the cartridge comprising:
- an end piece wall on the first end of the cartridge, the end piece wall having an outer periphery, the end piece wall comprising:
- an inlet tube extending from the end piece wall, the inlet tube having a distal end spaced apart from the end piece wall, the inlet tube enclosing an inlet flow passage in fluid communication with an inlet of the filter media;
- an outlet tube extending from the end piece wall and not coaxial with the inlet tube, the outlet tube having a distal end spaced apart from the end piece wall, the outlet tube enclosing an outlet flow passage in fluid communication with an outlet of the filter media;
- two lateral supports each extending laterally from a different one of the inlet and outlet tubes, each lateral support being spaced apart from the end piece wall in a direction parallel to the cartridge longitudinal axis;
- and
- a projection extending from at least one of the lateral supports along a longitudinal projection axis and in a direction away from the end piece wall, the two lateral supports joining each other and extending a distance less than that needed to extend beyond an outer periphery of the filter cartridge so the projection extends from a location within that outer periphery and the projection is spaced apart laterally from the inlet and outlet tubes.
A water filer cartridge having a first end, a closed second end, and a longitudinal axis extending through the ends, the cartridge having a filter media contained within the housing between the first and second ends, the cartridge having an end piece wall with a first and second fitting extending therefrom to form an inlet and outlet for the filter cartridge, the cartridge comprising:
- a lateral support extending laterally from each of the fittings, each lateral support being spaced apart from the end piece wall in a direction parallel to the longitudinal axis of the cartridge;
- and
- a projection extending from at least one of the lateral supports along a longitudinal axis of the projection and in a direction away from the end piece wall so the projection is supported vertically above the end piece wall and laterally offset from both fittings, the projection being spaced apart laterally from both fittings.
A water filer cartridge having a first end, a closed second end, and a longitudinal axis extending through the ends, the cartridge having a filter media contained within the housing between the first and second ends, the cartridge comprising:
- an end piece wall on the first end of the cartridge, the end piece wall having an outer periphery;
- a first fitting extending from the end piece wall along the cartridge longitudinal axis and having a first distal end spaced apart from the end piece wall a first predetermined distance, the first fitting enclosing a first flow passage in fluid communication with the filter media;
- a second fitting extending from the end piece wall along a second longitudinal axis having a second distal end spaced apart from the end piece wall a second predetermined distance so the second fitting is not coaxial with the first fitting, the second fitting enclosing a second flow passage in fluid communication with the filter media;
- two lateral supports, one extending laterally from each of the fittings, with the lateral supports joined together adjacent a distal end of the lateral supports, each lateral support being spaced apart from the end piece wall in a direction parallel to the cartridge longitudinal axis and spaced apart laterally from each fitting;
- and
- a projection extending from the lateral supports along a longitudinal axis of the projection and in a direction away from the end piece wall.
