ABC suction restrictor valve, component description - GF32.50-P-4101R
MODEL 230 as of 1.3.06 with CODE (487) Active Body Control (ABC)
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.
