ABSTRACT:
At least two radial piston pumps having a common eccentric rotatable within an eccentric chamber of the pump housing supply pressurized fluid to separate fluid circuits. The eccentric chamber is divided into separate fluid delivery compartments to which fluid is conducted from a common suction port by the pumps through passages that dampen the transfer of pressure fluctuations between the fluid circuits.
