摘要： Embodiments of a multi-port multi-plane valve are provided. The multi-port multi-plane valve includes a housing which defines an internal cavity. The housing further includes a plurality of ports in which each port lies within one of two planes that are normal to each other. Each of the plurality of ports is in communication with the internal cavity. A shell body is rotatably disposed within the internal cavity and provides selectable fluid communications between the ports. A seal member is also provided which has a plurality of openings and surrounds the shell body. At least one flow enhancer channel may be included to reduce the pressure drop occurring on one side of the valve when controlling flow paths on the other side of the valve.

摘要： A motor driven appliance timer utilizing a cam program disk and snap action switches is provided. The motor may be externally energized, or may be energized based on integrated electronics within the appliance timer. Rotation of the program disk by a user to allow selection of a desired appliance cycle is accommodated by a clutch subassembly that allows bidirectional rotation of the program disk without requiring that the user pull or push the control shaft before rotating the program disk. The timer of the present invention may utilize either impulse or constant drive mechanisms to rotate the program disk. The use of snap action switches minimizes the possibility of tack weld failures due to switch teasing.

摘要： A damper in a refrigeration system having a first compartment and a second compartment connectable through a passageway is provided. The damper comprises a damper door, a temperature responsive unit, and a heating element. The damper door is moveable between an open position and a closed position. The temperature responsive unit is operatively coupled to the damper door. The heating element is coupled to one end of the temperature responsive unit to conductively heat the temperature responsive unit when activated. The temperature responsive unit expands to move the damper door to the open position in response to conductive heating from the heating element.

摘要： A flow-through rotary damper assembly providing highly efficient, essentially laminar fluid flow therethrough is provided. The rotary damper assembly includes a cylindrical outer body and a cylindrical inner body that are rotatable in relation to one another. The outer body defines apertures in relation to one another to allow fluid flow without requiring fluid direction change. The inner body defines a flow passage having inlet and outlet apertures that may be aligned with the apertures of the outer body to allow fluid flow therethrough, or may be rotated out of alignment to block fluid flow. The outer body includes an aperture on one end to allow fluid flow to a third compartment. The inner body also includes an end aperture that may be aligned therewith. The damper provides selectable fluid flow between each of the compartments depending on the relative position of the cylindrical inner body member.

摘要： A system and method for refrigeration timer control having an energy efficient defrost cycle are provided. The system and method provide a delay time after the refrigeration cycle and prior to the defrost cycle. During this delay period the evaporator fan may run. The fan circulation and the heat from the fan coil provide a pre-warm cycle to the evaporator prior to the defrost cycle. To further enhance energy efficiency, the system and method may also provide a pre-refrigeration cycle after the defrost cycle. During this pre-refrigeration cycle only the compressor is energized. This prevents warm moist air from being circulated until the evaporator coils are cooled.

摘要： A damper assembly that produces bi-directional damper door movement from a single-direction motor is provided. Bi-directional rotation of the damper door is enabled by a cam slot on an end of the damper door that is engaged by a motor-driven drive cam having a drive pin extending into the cam slot. As the single-direction motor collectively rotates the drive cam and the drive pin, the drive pin reciprocates within the cam slot. This causes sealing flanges and the damper from the damper door to alternatively engage under a positive pressure and disengage from one another as the damper door is rotated bi-directionally.
