This tractor is equipped with the
remote control valve of the double
acting type. However, this valve can
also be used in the single acting type
hydraulic cylinder.
1. Connect one end of the hydraulic
port to the single acting cylinder as
shown in the figure. The hydraulic
pressure is properly supplied to the
cylinder. However, when the hydrau-
lic pressure is released, the cylinder
is contracted only if there is outer
force, such as potential energy.
SINGLE ACTING AND DOUBLE ACTING CYLINDER
(1) Single Acting Cylinder
(A) External load
H11O585A
2. To contract the cylinder, operate
the lever to the opposite direc-
tion of the expansion. Then, the
hydraulic fluid is supplied from the
hydraulic pump to the hydraulic
port which is not connected, and
the pressure rises as the port is
blocked. However, this pressure is
released as the relief valve opens.
3. When the cylinder is contracted,
the hydraulic fluid returned from
the cylinder is drained to the trans-
mission through the draining circuit
(2) double Acting Cylinder
m55o526A
as the operating lever is operated
to the opposite direction from the
expansion position.
It is recommended to use the
double acting cylinder instead
of the single acting cylinder if
the implement will be operated
frequently and continuously.
If using the single acting cyl-
inder too frequently or for an
extended period of time, the
hydraulic fluid can be over-
heated, resulting in deteriora-
tion of the hydraulic parts’ du-
rability as the main relief valve
opens at cylinder contraction.
