Two models for the estimation of the pressure evolution in high pressure variable displacement vane pumps are proposed: a lumped parameter model and an empirical model. The former has full physical meaning and allows to simulate the behavior of a wide pump range, the latter, based on experimental measurements, can be applied only to a single family of pumps. Both the models can simulate the pressure evolution around the rotor in working conditions. These results are important for the structural design of the pump. Moreover, these models are the first element of a combined model aimed at the dynamic simulation of this type of pump, as a tool for vibro-acoustical optimization. Copyright © 2013 by ASME.

Abstract
Two models for the estimation of the pressure evolution in high pressure variable displacement vane pumps are proposed: a lumped parameter model and an empirical model. The former has full physical meaning and allows to simulate the behavior of a wide pump range, the latter, based on experimental measurements, can be applied only to a single family of pumps. Both the models can simulate the pressure evolution around the rotor in working conditions. These results are important for the structural design of the pump. Moreover, these models are the first element of a combined model aimed at the dynamic simulation of this type of pump, as a tool for vibro-acoustical optimization.
