In load-sensing-systems a variable displacement pump A10VO
provides oil to the system - consisting of brake valve LT05, steering
unit LAGC and control block SB12. The pump’s delivery is varied
according to demand by means of the valve's LS signal that is fed back
to the pump. At the same time, a priority valve LPS ensures that the
brake and steering systems are given priority in the supply of oil.
The advantages are the demand-oriented supply to the consumers,
a flow control that is independent from the load pressure, precision
operation and electrical actuation via CAN bus.
