  • Patent number: 7321833
    Abstract: A valve body defines an inlet, an outlet, a valving cavity disposed between the inlet and outlet and a valving surface between the inlet and the outlet. A valve is moveable to a position away from the valving surface for permitting flow from the inlet through the valving cavity to the outlet. The fluid flow rate sensor includes a probe having a detection module adapted to change condition in response to the presence of the flow of the fluid, a control module that is electrically connected to the probe that monitors the condition of the detection module over time (e.g., a temperature), determines a rate of change of that condition over time, and generates an output that is indicative of the rate of flow of the fluid, and a I/O module connected to the control module and communicating the output of the control module to another device or a user.

  • Patent number: 7222642
    Abstract: A fluid valve assembly and method for assembling the same includes a valve body defining an inlet, an outlet and a fluid passage communicating fluid therebetween. A control member is positioned within the fluid passage and includes a central passage through which the fluid advances. A flow seat component is positioned in the valve body downstream of the flow control member and receives the fluid from the flow control member. A cap component is secured to a distal opening defined on the valve body. A quick-connect collet is retained within an opening defined on the cap component.

  • Patent number: 7032391
    Abstract: An icemaker assembly includes an ice tray has at least one ice forming compartment and an ice ejector having at least one ejector member. The ice ejector is operable to (i) stir water located within the at least one ice forming compartment with the at least one ejector member during a first mode, and (ii) urge ice out of the at least one ice forming compartment with the at least one ejector member during a second mode. A method of making ice comprises an operating an ice ejector of an icemaker in a first mode of operation step and an operating an ice ejector of an icemaker in a second mode of operation step. During the first mode of operation step, a plurality of ejector members of the ice ejector are respectively advanced through water located within a plurality of compartments of an ice tray of the ice maker during cooling of the water in the ice tray.

  • Patent number: 6532758
    Abstract: A water delivery system having increased flow rate properties for use in a refrigerator is provided. The water delivery system includes a pilot operated solenoid valve which feeds water to a water filter. The filtered water flows out of the filter to a second pilot operated solenoid valve. The second pilot operated solenoid valve has a first output which delivers water to a chilled water dispenser and a second output having a direct acting valve delivers water to an icemaker.
