PRODUCT INFORMATION
PRINCIPLE OF OPERATION OF JDN AIR
VANE MOTORS
The vane motor consists of a cylinder liner 1 with two side
bearing plates and an internal rotor 2.
The rotor 2 is mounted eccentrically in the cylinder liner 1 and is
provided with slots 3 for installation of the vanes 4.
The vanes 4 can move freely and make contact with the inner
wall 5 of the cylinder liner 1. Each chamber 6 is formed by two
vanes.
Due to the incoming compressed air, a greater force is created at
the leading, larger vane surface 4.1 than at the trailing, smaller
vane surface 4.2. The difference in force generates the torque of
the rotor 2.
As the chamber passes the outlet aperture 7, the compressed air
can escape.
Lubricant chambers 8 are provided between the vane slots of the
rotor 2. They ensure continual motor lubrication.
The arrows in the illustration indicate the direction of rotation of
the rotor 2 and the corresponding path of the compressed air.
