HYDRAULIC UNITS
CYLINDERS
OPERATION
Hydraulic oil flowing alternately in and out of the oil
outlet and inlet on both sides (head and rod sides) of
the piston acts on the piston and its force causes the
piston to move back and forth.
In cylinders equipped with a cushion mechanism,
the shock resulting from the piston colliding with
the cover at the stroke end acts on that mechanism
and is dampened by it.
Cushion Mechanism
Before the piston (1) nears the stroke end and col-
lides with the cover (2), the cushion bearing (3)
which precedes it enters the cushion seal (4), shut-
ting off the return passage for the hydraulic oil on
the rear end of the piston and making it possible for
oil to be expelled only along the groove provided in
the cushion bearing (3). This causes the piston (1)
back pressure to become high, slowing the speed of
the piston.
