2. Control of discharge
• If swash plate angle (a) is increased, the differ-
ence between volumes E and F is increased, and
so discharge Q is increased. Swash plate angle
(a) is changed with servo piston (10).
• Servo piston (10) reciprocates straight according
to the signal pressure of the servo valve. This
straight motion is transmitted to rocker cam (4).
Then, rocker cam (4) supported on ball (11)
slides around ball (11).
