Abstract
A pump exerts pressure on fluid that has higher saturation pressure than atmospheric pressure at room temperature in a fluid reserving chamber in a fluid tank. The pump is located near the fluid tank. The pump has a housing and a heat generating mechanism. The housing defines a pump chamber, a motor chamber and a communication passage between the pump chamber and the motor chamber and includes at least one introducing port for introducing the fluid from the fluid reserving chamber into the housing and a bleeding port located above the introducing port for returning the fluid from the housing to the fluid reserving chamber. The heat generating mechanism is located in the housing. The fluid circulates into the housing through the introducing port and out of the housing through the bleeding port for substantially reducing the temperature in the housing.
