Hydraulic Motor/Pump
Series V14
AC control function
Refer to the illustration below left:
When pressure in port A (or B) increases, the
servo valve spool is pushed to the right,
directing flow to the right hand setting
chamber - the setting spool moves to the left;
displacement and output torque increases. At
the same time, the shaft speed decreases
correspondingly (at a constant pump flow to
the motor).
AC control function (displ. increase at increasing
pressure).
Refer to the illustration below right:
When pressure in port A (or B) decreases,
the servo valve spool moves to the left,
directing flow to the left hand setting chamber
- the setting spool moves to the right; dis-
placement and output torque decreases.
At the same time, the shaft speed increases
correspondingly (at a constant pump flow to
the motor).
AC control function (displ. decrease at decreasing
pressure).
