EXCERPT:

FUNCTION
When the OLSS mode is set to H mode, the discharge flow from the pump is controlled to the optimum by the command current from the controllerto match the change in the engine speed.
In S mode or L mode, and when the prolix switch is ON, the pump discharge flow is controlled to match the pump discharge pressure (load) by hydraulic sensing in accordance with a constant pump absorption torque.
* For details, see MACHINE CONTROL SYSTEM.

OPERATION
Because of the command current sent from the controller, solenoid push pin (10) moves, and piston (2) also moves. When this happens, it stops at a point where the sum of the force of spring (1) and the force of push pin (10) and the force of TVC output pressure Pe acting on piston (3) is in balance. At this point, the command current is small, so piston (2) is balanced at the bottom.
As a result, ports a and b are both almost completely open, and almost all the pressure oil from the charging pump output as TVC output pressure Pe.
For this reason, the pump discharge volume becomes the maximum.
