    摘要： A control is provided that includes a sensor that provides an output indicative of a sensed temperature of a condenser coil of the heat pump, and a controller for controlling activation of at least a compressor of the heat pump. The controller is configured to compare the output of the sensor to a representation of sensed ambient temperature to determine whether the reversing valve is in heat mode where the sensed ambient temperature exceeds the sensed temperature of the condenser coil, or in cool mode where the sensed ambient temperature is less than the sensed temperature of the condenser coil. The controller is further configured to deactivate at least the compressor of the heat pump when the reversing valve is determined to be in a mode that is inconsistent with the heat pump's heating operation or cooling operation.

    摘要： A faucet includes a valve body having a cartridge receiving bore. A valve cartridge is sealingly disposed in the bore. The valve cartridge includes a rotatable stem. An arc-shaped slot is created in the valve cartridge. A lever assembly having a single handle is connected to the stem and operates when rotated in a first direction to permit cold water flow through the valve body, and after being depressed can be rotated in an opposite second direction to permit hot water flow through the valve body. A torsion spring has a first post received in the elongated slot translatable between opposed ends of the elongated slot, and a second post received in a lever assembly aperture preventing second post translation. A biasing force of the torsion spring biases the lever assembly toward a valve closed position only when the lever assembly is rotated in the second direction.

    摘要： A controller is provided for a gas valve including a movable valve element, a main diaphragm chamber having a main diaphragm therein coupled to the valve element to displace the valve element relative to a valve opening, and a servo-regulator diaphragm for regulating flow of gas that acts against the main diaphragm, to adjust the valve element and vary the flow rate. A stepper motor is configured to move in a stepwise manner to displace the servo-regulator diaphragm to adjust the valve element and gas flow rate. The controller for the stepper motor includes a microprocessor that receives an input signal indicating an operating capacity level, and determines the steps the stepper motor must move to displace the servo-regulator diaphragm to establish a flow rate corresponding to the operating capacity level. The microprocessor generates a signal to move the stepper motor the number of steps to adjust the gas valve.
