DESCRIPTION OF THE CYLINDER COMPONENTS
The cylinder pistons are single-acting types (fig. A).
TELESCOPIC CYLINDER WITHOUT BRAKING EFFECT
In these cylinders a seal (1) has been fitted on the
piston (2) that works on the inner surface of the
cylinder liner (3).
The rod guide is made by the plug (4) and by the
piston through anti-friction rings (5).
The dust control ring (6) prevents any dirt and water
from penetrating the cylinder.
Slight leakages that may occur are directed to the
tank through the drain pipe connected to the pipe
coupling (7).
The drain pipe shall reach the oil tank (fig. B)
A small quantity of oil will always remain in the loop
formed by the pipe before connecting to the tank. It
acts as a trap and constantly moisturizes the cylinder
liner, when it is completely closed (fig. B).
