SINGlE.ACTING.AND.DOUblE.ACTING.CylINDER
(1) Single Acting cylinder
(A) External load
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.

(1) double Acting cylinder
2. To contract the cylinder, operate
the lever to the opposite position 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. How-
ever, this pressure is released as
the relief valve opens.
