Abstract

A vane pump assembly which uses a biasing means for regulating the internal and maximal output pressure of the vane pump rather than the maximal output of the pump motor. The pump assembly includes a motor having an output drive shaft, a housing having a front end and a rear end seated on the motor, a cylindrical member received Within the housing, first and second closure members which overlie the respective front and rear ends of the cylindrical member, a cylindrical hub eccentrically received on the drive shaft within the cylindrical member, a plurality of vanes disposed about the cylindrical hub, a cap member covering the front end of the pump housing, and a resilient means disposed between the motor and the second closure member for selectively biasing the cylindrical member between the first and second closure members and enabling the pump to develop a preselected maximum output therefrom without halting rotation of the cylindrical hub. The biasing means is interchangeable to provide variable maximal degrees of output pressure. The pump assembly is integrable into a seat support system.
