Abstract
An integrated pump and accumulator assembly for use in a system circulating a liquid coolant or the like. A housing defines a pump chamber and an integral closed accumulator chamber. A pump is disposed in the pump chamber and includes a coolant circulating inlet and an outlet. A hermetically sealed expandable and contractable reservoir is disposed in the accumulator chamber. A liquid conduit communicates between the pump chamber and the accumulator chamber on one side of the expandable and contractable reservoir whereby expansion and contraction of the coolant is accommodated by the reservoir. The accumulator chamber is charged with a gas on an opposite side of the reservoir.
