A hydraulic pump has a rotor and a hollow housing with a main interior chamber. The rotor is rotatably mounted in the main interior chamber. A smaller interior chamber is separated from the main interior chamber such that the smaller interior chamber retains gas therein when the main interior chamber is filled with a liquid.

A hydraulic pump has a rotor and a hollow housing with a main interior chamber. The rotor is rotatably mounted in the main interior chamber. A smaller interior chamber is separated from the main interior chamber such that the smaller interior chamber retains gas therein when the main interior chamber is filled with a liquid. There is also a method for accommodating changes in volume of hydraulic fluid within the main chamber of the hydraulic pump housing. The method comprises providing the smaller interior chamber separated from the main chamber and retaining gas within the smaller chamber when the main interior chamber is filled with liquid, whereby expansion or contraction of the gas accommodates changes of volume of the liquid within the housing.
