|20130302142||ELECTRIC FLUID PUMP - 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.||11-14-2013|
|20110110801||FLUID PUMP FOR DELIVERING COOLED WORKING FLUID IN AN ENGINE COOLING SYSTEM - A fluid pump for delivering cooled working fluid in an engine cooling system includes a housing unit defining front and rear chambers, an inlet disposed upstream of a central region of the front chamber, an outlet disposed downstream of a surrounding region of the front chamber, a canister member dividing the rear chamber into stator- and rotor-side spaces for receiving a stator and a rotor, respectively, a hollow shaft which is rotated with the rotor to turn an impeller in the central region and which defines a passage, and an auxiliary conduit communicated with the inlet and the rear chamber so as to divert part of the working fluid to flow through the internal duct and the passage, thereby diffusing heat generated within the housing unit.||05-12-2011|
|20100054977||VARIABLE DISPLACEMENT PUMP - A variable displacement pump includes a pump body defining first and second pools for introducing fuel/lubricant oil, and internal and external rotary members rotatably mounted on the pump body and cooperatively defining a space such that, during counterclockwise revolution, the fuel/lubricant oil is taken up from the first pool by sweeping of the space over the first pool, and is delivered to the second pool. A control slider is sleeved on the external rotary member, and has an actuated tooth moved by an expansion force in the second pool to counteract the external rotary member so as to reduce the volume of the space, thereby reducing delivery of the fuel/lubricant oil into the second pool. A biasing member is disposed to bias the actuated tooth towards the second pool.||03-04-2010|
