Patent number: 9163635Abstract: An electric water pump includes a housing, a propelling mechanism disposed in the housing, and a driving mechanism for driving a driving shaft of the propelling mechanism. The driving shaft has a fluid passage in fluid communication with an impeller chamber and a cooling chamber in the housing. The propelling mechanism further includes a spiral rod disposed in the fluid passage and co-rotatable with the driving shaft, and an impeller disposed in the impeller chamber. During operation of the propelling mechanism, the impeller drives flow of a fluid, and the spiral rod co-rotates with the driving shaft to change the rate of the fluid flowing through the driving shaft.Type: GrantFiled: September 14, 2012Date of Patent: October 20, 2015Assignee: JI-EE INDUSTRY CO., LTD.Inventors: Arthur Chiu, Triven Lin, James Chien

Patent number: 9046087Abstract: A motor pump unit for a high-pressure cleaning apparatus has an electric motor and a pump. The electric motor has a motor housing that is surrounded by a cooling housing with an annular space having an annular space inlet and an annular space outlet formed therebetween. The pump has a suction inlet connected to the annular space outlet and a pressure outlet. The liquid to be transported by the pump can be supplied to the annular space inlet. In order to improve the motor pump unit such that the motor housing can have a small wall thickness and can still be cooled effectively over a large surface area, the motor housing is configured as a one-piece deep-drawn part which in a front shell area contacts stator laminations of the electric motor and in a rear shell area is arranged at a distance from rear coil heads of the stator and in the rear shell area has stiffness-enhancing depressions, wherein the front and the rear shell areas are surrounded by the annular space.Type: GrantFiled: August 4, 2011Date of Patent: June 2, 2015Assignee: Alfred Kaercher GmbH & Co. KGInventors: Walter Schiffhauer, Lanfranco Pol

Patent number: 8920136Abstract: A turbomachine includes a motor including a rotor assembly and a stator assembly. A sleeve fluidly separates the rotor assembly from the stator assembly. The sleeve has first and second ends axially spaced from one another. In one example, first and second seals are arranged at the first end and fluidly separate the rotor assembly from the stator assembly. The second seal is arranged downstream from the first seal relative to the rotor assembly. In another example, the sleeve includes wet and dry sides. A first seal is arranged at the first end on the wet side. A drain is provided in the housing and arranged in a region downstream from the first seal. The drain fluidly connects the region to an exterior of the housing.Type: GrantFiled: January 11, 2012Date of Patent: December 30, 2014Assignee: Hamilton Sundstrand CorporationInventors: Craig R. Legros, Aaron M. Finke
