The space at the bottom of the blades in a single-acting vane pump is generally small. A. Oil inlet and outlet chamber B. Oil suction chamber C. Not connected to either the suction or outlet chamber D. The suction and outlet areas are each connected to their respective suction and outlet chambers. Hint: In a single-acting vane pump, the speed at which the elements extend outward in the suction area is slower than that in a double-acting pump; the centrifugal force of the vanes is sufficient for this purpose. Connecting the bottom part to the suction chamber reduces the pressure exerted by the vanes on the stator, thereby reducing wear.
