SINGLE-ACTING HYDRAULIC SYSTEMS
A basic single-acting hydraulic system consists of a manual or power pump that moves the hydraulic fluid, a hydraulic
hose that carries the fluid, and a cylinder or ram that the fluid moves to do a job.

DOUBLE-ACTING HYDRAULIC SYSTEMS
A basic double-acting hydraulic system consists of a pump (which moves the hydraulic fluid), a double-acting cylinder
or ram (to do the work), a hydraulic hose (which routes the fluid to the advance cylinder or ram port), a second hydraulic
hose (which routes the fluid to the retract cylinder or ram port), and a control valve which can change the direction of the
hydraulic fluid.

Cylinder
Since the single-acting cylinders have only one
hose going to the cylinder, the cylinder can only
apply force to extend (pull cylinders retract) its
rod. The return stroke is accomplished by gravity
or spring force.
Spring Return
A double-acting cylinder or ram can be either extended or
retracted hydraulically.
Most double-acting cylinders or rams are classed as
"differential cylinders" because of the different sized
areas that the hydraulic fluid pushes against during the
extend and retract strokes. Because of this difference,
the extend stroke can exert more force than the retract
stroke.
