Location

The ABC suction restrictor valve is located on the tandem pump

Task/function

The hydraulic pressure supply is implemented by means of a suction-restricted radial piston pump. In order to achieve a constant oil pressure, the ABC control unit (N51/2) must perform a supply pressure control function.

The intake volume of the radial piston pump is controlled according to the current consumption by means of the ABC suction restrictor valve, a proportioning valve which is closed when de-energized. The 250 bar ABC pressure sensor (B4/5) serves as a measuring element.
