Flow Rate Increase Instructions

To adjust the flow rate:

1. Activate the control lever to shift the flow rate control valve, increasing pump control pressure (Pi).
2. The piston pushes spool A and spring, moving spool A in the arrow’s direction.
3. This opens the circuit from the large chamber of the servo piston to the hydraulic oil tank.
4. Primary pilot pressure Pg moves the servo piston, rotating the cylinder block for maximum pump delivery flow rate.
5. Movement is translated to sleeve A via link, closing the circuit from the servo piston to the oil tank.
6. The flow rate increase process completes as the circuit closes, stopping the servo piston.
