Control Lever Activated (First Step: Moving the Control Lever)
When moving the control lever (step on the pedal), and the feedback lever (7) connected with the regulator spool
(3) goes against the servo piston (8). Such resistance pulls the regulator spool from the feedback lever. As a result,
the hydraulic circuit is formed as shown here.
The servo piston is affected by the charge pressure and starts moving in the direction of arrow.
