Modulus B of the liquid volume elasticity of non-aerated and aerated oil is defined in the paper as relation to the indicated increase of pressure in the pump working chambers, with the change of oil temperature and degree of aeration. In evaluation of the losses due to oil compressibility in a variable capacity displacement pump, the volume of compressed liquid at each pump setting is taken into account. Volumetric losses have been divided into leakage losses in the pump chambers and losses due to liquid compressibility. The need of accounting for only the leakage losses for pump evaluation is pointed out.
