    摘要: A single magnetic coil floating plunger redundant gas valves is disclosed. In an illustrative embodiment, the valve may include a first plunger tube, a second plunger tube spaced a distance from the first plunger tube, a magnetic coil disposed about at least part of the first plunger tube, a first plunger disposed within the first plunger tube, and a second plunger disposed within the second plunger tube. The first and second plungers may be operatively coupled to first and second valve members. Activation of the magnetic coil may result in the first and second plungers being suspended in the plunger tubes without a hard mechanical plunger stop to selectively open corresponding valves or other actuatable components, as desired.

    摘要: An energy savings water heater is described. The water heater is controlled by an energy savings algorithm that uses one or more of a variable setpoint differential, a variable setback threshold, additional setback thresholds, and an adjustable minimal setpoint to improve the operation of an energy efficient water heater. Additionally or alternatively, a different setback control algorithm may be used that obtains additional data to adjust the setpoint. As a result, the operating cost of the water heater is reduced, while minimizing user complaints of cold water.

    摘要: An actuator suitable for use with a valve has a design allowing for easy control or adjustment of the force applied to the valve. The actuator motor has a cam which operates a follower surface of a spring-loaded arm mounted for rotation on a carriage. The carriage is mounted for linear motion and connected to the control element of the valve. The actuation force can be controlled or adjusted by changing the relative positions of the arm's center of rotation, the point on the arm at which the spring applies force, and the position of the cam. In a preferred embodiment, the position of the arm's center of rotation is changed by moving a pin from one set of holes in the carriage and the arm to a second set of holes in the carriage and the arm.
