Adequate provision for minimizing the effect of distortion of the working parts, casings, ect., due to the internal pressure in the pump. f. Low clearance volumes so that the pump will act momentarily during priming, or with aerated fluid, as a pressor, to discharge the air through the delivery line, instead of leaving it taped in the pump. g. Adequate inlet valve or port provision to enable the pump to create a good suction, or alternatively, as in the case of aircraft, to operate at high altitude, and with relatively thick fluids. It should be noted that the time of opening of the inlet valve or port is almost as important as the size of the port. The main requirements of a good pressor are
