摘要：

In this paper the results of the numerical determination of the pressure variation of the working fluid for external gear pumps with symmetric and asymmetric tooth profiles have been given. It is shown that for pumps with asymmetric teeth profiles, the pressure variation is more uniform as with symmetric teeth profiles. Regardless of the shape of the teeth, the greatest pressure drop is the pressure on the first teeth spaces in relation to the intake chamber, due to the difference in radial clearance for the different teeth as a result of the eccentric arrangement of the gear relative to the pump case.
