摘要： A lid assembly being attached to a pressure vessel includes a filter access cap having a top portion, a bottom portion, and a tubular portion extending from the top portion to the bottom portion to define a throughhole, the top portion having a radial slot. The lid assembly includes a seal plate assembly connected to the bottom portion of the filter access cap and configured to rotate relative to the filter access cap to assist in releasing a pressure from the pressure vessel, and a relief valve for releasing non-atmospheric pressure when opened. Further, the lid assembly includes a seal stem located in the throughhole, wherein the relief valve is mounted in the seal stem, and an arm operatively engaging the relief valve and having a proximal end pivotally secured to the lid assembly, whereby when the arm is pivoted in a first direction the relief valve can be opened.

摘要： A split case adapted to hold water filtration units in a water filtration subassembly. The interior of the case holds three water filtration units arranged in series. The filtration units are in fluid communication with each other through fluid connectors. The assembly includes a water input member and a water output member, each generally positioned at opposing ends of the split case, each partially exposed to the space outside the case through apertures in the walls of the split case, and each providing fluid communication between the outside world and the water filtration subassembly.

摘要： Provided is a head assembly for a water purification filter, which includes a head body, a rotation shaft, and a fastening cap. In particular, the rotation shaft is rotated in the state of being placed on a seat protrusion formed on the head body, and a lower seal member is disposed in the portion where the rotation shaft is placed on the seat protrusion. Accordingly, there can be prevented a problem in which the lower seal member departs from a predetermined location during the coupling of the rotation shaft to the head body so that defective assembly occurs.

摘要： A filter cartridge for operatively coupling to an appliance interface to treat a fluid, such as water, being supplied to the appliance. The interface comprises a bypass valve for actuating the interface between a bypass mode in which the fluid flowing through the interface does not flow through the filter cartridge and a treatment mode in which the fluid flowing through the interface is directed through the filter cartridge for treatment by the filter cartridge. The filter cartridge comprises a cartridge housing having a first end and a second end and extending along a housing longitudinal axis through the first end and the second end. A filter media is contained within the cartridge housing between the first end and the second end. The filter cartridge also has a first end cap on the first end of the cartridge housing and a second end cap on the second end of the cartridge housing. A bypass valve actuator is attached to the cartridge housing and extends distally to an actuator distal end. The bypass valve actuator is configured such that the actuator distal end actuates the bypass valve of the interface as the filter cartridge is coupled to interface.

摘要： Disclosed is a filter coupling device having joint members, a base plate, a filter holder, a rotation shaft, and a leg. The filter holder allows support of a first filter and a second filter. The rotation shaft is connected with the filter holder. The filter holder takes a first attitude and a second attitude by rotating around the rotation shaft. The filter holder includes a first filter holder configured to support the first filter in the first attitude, and a second filter holder configured to support the second filter in the second attitude.

摘要： 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.

摘要： A draw latch retainer is used to secure a filter cartridge to a filter head. A cam actuated retainer extends from the head to engage a keeper in the top of the cartridge. Rotation of the cam draws the retainer and cartridge axially toward the head into an installed position. The retainer extends through an aperture in the upper portion of the cartridge to apply a retention force against the bottom side of the keeper. The keeper and upper portion of the cartridge supporting the keeper are configured to transmit the retaining force laterally across the top of the cartridge. A pair of axial conduits project from the cartridge and mount O-ring seals for implementing an axial sealing interface with passages in the head.
