4. High and Low Speed Switching Device
E. At low speed (If the pilot pressure is lower than 10 kg/cm 2 )
If pilot pressure is not applied from port A (If the pressure is lower than 10 kg/cm 2 ), the valve
(163) is pushed to the left by the spring (I66) force, the pressure oil from the supply port B is
blocked, and the oil of the chamber C flows through the valve (l63) into the motor case. So it
rotates at low speed because the swash plate (103) is tilted to the maximum angle, and the
piston stroke volume is maximized.
