Adjustment of outer spring
Adjust it by loosening the hexagon
nut(630) and by tightening(Or loosening)
the adjusting screw C(628). Tightening
the screw shifts the control chart to the
right and increases the input
horsepower as shown in the figure.
Since turning the adjusting screw C by N
turns changes the setting of the inner
spring(626), return the adjusting screw
QI(925) by N

Low tilting angle(Low flow) command preferential function
As mentioned above, flow control and horsepower control tilting angle commands are transmitted
to the feedback lever and spool via the large-hole sections(C & F) of levers 1 and 2. However,
since sections C and F have the pins(
ٻ
4) protruding from the large hole(
ٻ
8), only the lever
lessening the tilting angle contacts the pin(897) ; The hole(
ٻ
8) in the lever of a larger tilting angle
command is freed without contacting the pin(897). Such a mechanical selection method permits
preference of the lower tilting angle command of the flow control and horsepower control.
Adjustment of input horsepower
Since the regulator is of total cumulative horsepower type, adjust the adjusting screws of both the
front and rear pumps, when changing the horsepower set values. The pressure change values
by adjustment are based on two pumps pressurized at the same time, and the values will be
doubled when only one pump is loaded.
