  • Patent number: 9032993
    Abstract: A damper system may include a handle mechanism for use with a damper actuator system. Illustratively, the handle mechanism may include a drive gear mechanism, a handle, a housing, and a spring, and may be actuated to set a crack pressure for the damper system. The handle may connect to the drive gear mechanism at a drive gear arm of the drive gear mechanism and may flip over or about the drive gear arm to move from a first position to a second position. In some instances, once the handle is in the second position, a force may be applied thereto to disengage the drive gear from a stop member and thereafter, the handle may be rotated to change the crack pressure of the damper system.

  • Patent number: 9033192
    Abstract: A rotary actuator suitable for use in a refrigerator ice-dispensing door provides a rotating shaft driven by a DC permanent magnet motor through a gear train and subject to a returning force of an internal spring. The gear train communicates with a switch to reduce current to the motor when a limit of travel is reached and a shunting path is provided around the motor to produce generative braking when power is removed from the motor and the actuator rotates backward to its initial position.

  • Patent number: 8960637
    Abstract: An electronically controlled stepper motor valve utilizes an electric feed through assembly providing electrical connection between the stepper motor and a mating cable connector; wherein the electric feed through assembly includes four individual leads that are sequenced to allow the mating cable connector to be installed in any of four positions, each 90 degrees apart. The ability to use a 90 degree elbow style cable connector allows the EEV footprint to be minimized which provides an advantage when the electric expansion valve is installed in the tight confines of a package system.
