Abstract
A liquid pump includes a pump assembly attached to a motor. The pump assembly includes an inlet chamber and pump chamber. The pump chamber accommodates a drive gear driven by an output shaft of the motor and driven gear meshed with the drive gear. An inner cover is disposed within the pump chamber. An outer cover overlies the inner cover with an elastic member disposed there between. The outer cover exerts a force to the inner cover through the elastic member and holds the inner cover in sliding contact with an axial end of the drive and driven gears. An outlet chamber formed between the inner cover and the outer cover is in fluid communication with and the pump chamber.
