The vane motor consists of a cylinder liner
1
with two
side bearing plates and an internal rotor
2
.
The rotor is mounted eccentrically in the cylinder liner
and is provided with slots
3
for installation of the vanes
4
.
The vanes can move freely and make contact with the
inner wall
5
of the cylinder liner. Each chamber is formed
by two vanes
6
.
Due to the incoming compressed air, a greater force is
created at the leading, larger vane surface
4.1
than that
at the trailing, smaller vane surface
4.2.
The difference
in force generates the rotor torque.
As the chamber passes the outlet aperture
7
, the com-
pressed air can escape.
Lubricant chambers
8 are provided between the vane
slots of the
rotor. They ensure continual motor lubri-
cation over a period of 250 - 500 operating hours
(depending upon motor type).
The arrows in the illustration indicate the direction of
rotation of the rotor and the corresponding path of the
compressed air.
