Component Identification:
Location
The ABC suction restrictor valve is located on the tandem pump.
Task
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 to match the current consumption using the ABC suction restrictor valve, a proportioning valve which is closed when de-energized. The ABC pressure sensor (B4/5) serves as a measuring element.
