Abstract: Provided are embodiments of a gas valve for an intermittent pilot ignition system. The gas valve includes features designed to address the buildup of negative pressure in a fuel line connected to the gas valve that could cause internal valve diaphragms to open, drawing fuel from the gas valve. In embodiments, the gas valve includes a system of check valves designed to seal off the gas valve when a negative pressure develops. In other embodiments, the gas valve includes a relief valve having a relief port so that air is able to enter the valve proximate to the inlet port so as to avoid building a negative pressure sufficient to open the diaphragms. In both cases, the valve remains primed with fuel for subsequent ignition. The gas valve is envisioned to be useful for a variety of pilot operated systems.

Abstract: A stepper motor driven modulating gas valve and system are provided. Such a system includes an electronic controller, a touch user interface, and a stepper motor. The system also includes a variable flow gas valve having a rotatable valving member for controlling a variable flow of gas therethrough, the valving member having an input shaft, and a gear train operatively coupling the output shaft of the stepper motor to the input shaft of the valving member of the variable flow gas valve. A burner is coupled to the variable flow gas valve. The electronic controller receives a user input for flame selection via the touch user interface and energizes the stepper motor to position the variable flow gas valve valving member to a predetermined angular position through the gear train to provide a flow of gas to the burner that will provide the user's desire flame intensity.

Abstract: An ice pusher is provided. The ice pusher incorporates a cam and a linear actuation arrangement for removing ice from an evaporator plate of an ice-making machine. The cam provides a helix shaped ramp structure having a cam surface. The linear actuation arrangement has an input end and an output end. The input end is in slidable contact with the cam surface such that the linear actuation arrangement linearly moves relative to the housing upon rotation of the cam to effectuate the removal of ice from the evaporator plate.

Abstract: A one time high fill pressure switch providing energy savings operation for use in a commercial or consumer appliance such as a clothes washing machine is provided. The one time high fill pressure switch provides multiple water level settings that may be selected by a user, including a maximum fill energy savings setting. Operation in the maximum fill energy savings setting allows a maximum fill level upon the first fill cycle of the programmed washing cycle. In subsequent fill cycles during the washing cycle, the one time high fill pressure switch limits the water level to a setting below the initial fill level setting. This operation is provided through the use of a hook feature on the pressure switch program cam that traps a reset spring support and is controlled by a cam follower in the pressure switch.

Abstract: 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.

Abstract: A program timer for use with commercial or consumer appliances provides a single user knob interface that allows the desired selection of a programmed cycle and a push-to-start function. To preclude inadvertent program operation and enhance the life of the program timer, a snap-action switch is utilized to provide the push-to-start functionality. As such, actuation of the start switch provides a positional hysteresis that prevents teasing of the switch. The rapid snap-action opening and closing of the switch contacts precludes or minimizes the arc sustained between the contacts so as to greatly increase the life of the start switch. In one embodiment an actuation wheel larger in diameter than the program cam stack of the timer is utilized to pivot a lever to actuate the snap-action switch.
