Appl. No.:

12/136873

Inventors:

Benno Lebkuchner - Thompson CT, US
Hans L. Kuster - Barrington RI, US

Assignee:

AquaMotion, Inc. - Barrington RI

International Classification:

F04B 35/04

US Classification:

41742312, 41742314, 41742315

Abstract:

An improved motor pump that enables the serviceability thereof, as well as improved clearance between components of the motor pump, the motor pump including a stator assembly, a rotor assembly having a front bearing for supporting a motor shaft and a bearing support member for receiving the front bearing, and a sleeve assembly including a sleeve. Both the bearing support member and the sleeve have respective pilot sections. An interface surface is defined between the bearing support member and the sleeve that includes an undulating surface with separate but multiple contact locations therebetween. The bearing support member is inserted into the sleeve so that the respective pilot sections engage to thus provide essentially a clearance-less fit therebetween.

Abstract:

A bearing that is used in a motor pump in which a liquid is, not only pumped by means of an impeller driven by the pump, but also is used to lubricate components of the motor pump including the motor pump shaft. The bearing is for supporting the shaft at at least one location of the shaft. The bearing is constructed of a bronze material having added thereto a small amount of graphite, preferably around 2. 5%.

Abstract:

A water circulating system is for distributing instant hot water at a fixture that has respective hot and cold water inlets. The system includes hot and cold water piping, a pump constructed and arranged to pump water through said hot water piping. A by-pass device is provided at the sink area and connected directly between the hot water inlet and the cold water inlet. The by-pass device includes a pump for drawing hot water, a thermal switch, and a check valve. The pump, thermal switch, and check valve are constructed and arranged in series. A controller is connected to the pump so as to control the duty cycle of the pump so as to establish at least one of a selectable pump cycle time, and a selectable pump running time.

Abstract:

A de-aerator apparatus for removing gas from fluid flowing through a pipe includes a housing having a chamber, an inlet connected to an inlet pipe for allowing the passage of fluid into the chamber, an outlet connected to an outlet pipe for discharging fluid from the chamber, and a vent for venting gas from the top of the chamber. The arrangement is such that as fluid flows into the chamber through the inlet and out of the chamber through the outlet, relatively large gas pockets present in the fluid in the chamber rise to the surface of the fluid and exit the chamber through the vent. A device disposed within the chamber has bristles facing the flow of fluid into the chamber through the inlet. The bristles vibrate for merging micro gas pockets present in the fluid with one another to produce large gas pockets which rise to the surface of the fluid within the chamber and exit the chamber through the vent.
