of vanes 78 causing impeller 76 to rotate in the direction shown by arrow 85 such motion of impeller 76 also causes shaft 80 to rotate shaft 80 extends outward from body 71 to provide a drive shaft for a connected pump the pressurized fluid passes through cavity 83 to outlet fluid channel 74 when vane pump assembly 70 is utilized as a pump shaft 80 causes impeller 76 to rotate as the impeller 76 rotates and a second unpressurized fluid enters the pump the vanes 78 are pushed to the wall of body 71 forming a tight seal as impeller 76 rotates the vanes force such second fluid into the crescent shaped cavity and sweep the fluid toward the fluid outlet channel 74 other combinations of fluid motors and pumps having a common rotating shaft shared between the motor and pump can be used such as a gear motor as described with reference to fig1 and 2 and a vane pump as described above in such a case the shaft of one of the gears in the gear motor drives the impeller of the vane pump in another embodiment a vane pump assembly can be used as a fluid.
