Abstract
A water filter cartridge has an end cap with separate inlet and outlet nozzles connected to the end of a cylindrical tube that extends from the end cap. The nozzles are slanted and laterally offset from the cylindrical tube. A cam surface on the outer side of the nozzles actuates valves in a mating manifold. The passage in the nozzles is conical, expanding toward the nozzle end and opening onto a portion of the nozzle side to form a sharper tip. Expanding ice pushes itself out of the conical passage and facilitates ice removal. The narrow end of the conical passage facilitates breakage and removal of ice from the nozzle.
