摘要： An improved, wholly mechanical, valve unit is provided to automatically allow for flow between a high temperature liquid line and a cooler temperature liquid line in order to maintain the immediate availability of hot liquid immediately upstream of the valve, especially for hot water used in a building. The valve unit of the present invention includes a thermally-activated, bi-metal, or more broadly bi-flexive, valve disc, and a smaller diameter valve seat that concentrically contacts the valve disc intermediate the outer circumference and the center of the disc. The bi-flexive disc is provided two-sided, circumferential support, thus substantially equalizing the pressure against both sides of the disc, even when in the closed valve position between the higher temperature, higher pressure, hot water line and the lower pressure cold water line. The valve opens when the temperature differential across the valve disc decreases below a preset amount.

摘要： A relatively small water pump-DC motor combination, powered by batteries, provides sufficient pump power to create the flow between the hot and cold water lines necessary to maintain a substantially immediate hot water response when the hot water tap is opened. The pump is controlled by a thermal sensor signaling the pump to commence operation when the temperature in the hot water line upstream of the hot water tap is less than a predetermined value. Preferably, each of the batteries is rechargeable, most preferably utilizing a wireless system, where the power source is a distance away from the pump battery, to provide additional protection against electrical short circuits in the presence of water. Commonly available batteries of between 10 and 24 Volts can be used.

摘要： A brushless DC motor comprises a permanent magnet rotor rotating coaxially with and inside of the stator, separated by a radial, axially extending gap. The rotor can be formed of four or more permanent, e.g., ferrite ceramic magnets, spaced substantially equidistantly circumferentially around the rotor and extending radially along the axial length of the rotor. The preferred ferrite magnets are substantially corrosion resistant, and thus durable in the wet rotor environment, in which it may be used, sufficient to withstand the effects of even hot salt water. Preferably, four of the permanent magnets are bar magnets, i.e., rectangular in cross-section, extending radially and perpendicularly to the adjacent magnets. Most preferably, the bar magnets are separated by generally wedge-shaped, or quadrant-shaped, sections of magnetic material. The permanent magnets are polarized so that the north-south flux lines extend transversely to each adjacent magnet, most preferably forming a so-called Halbach Array.

摘要： An integrated wet-rotor zoning circulator for circulating fluid within a zone in a hydronic heating or cooling system. The zoning circulator has three primary components: a motor (100), an impeller casing (300), and a controller (200). The controller (200), which is integrated with the motor (100), houses a voltage transforming device (e.g., a transformer) (208) and a switching device (e.g., a relay) (213). When a thermostat (215) in the zone being served by the zoning circulator closes, the switching device (213) closes and the pump is activated.

摘要： A zone valve for a hydronic system (either heating or cooling) in which a motor-driven actuator (200) rotates a ball valve (130) through approximately 90°, between closed and opened positions. The ball valve provides lower flow resistance than that of conventional heat-motor and motorized zone valves, allowing the use of lower rated pumps, and allowing a single size valve to serve most applications. A restoring torque is provided by a tension spring (346) so configured that it provides sufficient restoring torque to overcome the frictional torque of the ball valve (130). The restoring torque is kept from building up during rotation by configuring the spring in such a manner that its force varies inversely with the effective moment arm. The restoring torque varies by no more than 20 % (preferably no more than 10 %) during rotation of the ball valve. This assures that enough torque is always available to restore the valve to its closed (or open, in a normal open case) position, after the motor (200) is deenergized, but that there is not too much torque for the motor to overcome when it moves the valve (130) into the open position.
