3 Design and Function
3.1 Control Unit
Fig. 2: Control Unit operation
Air reaches into the distributor block (2) of the con-
trol unit via the compressed air connection (3). The
valve (4) in the distributor block (2) controls the air
intake to the motor. The air outlet is through the
two sound mufflers (1).
3.2 Motor
Fig. 3: Motor operation
The pneumatically operated motor drives the
pump. The piston (4) of the motor divides the cyl-
inder (3) into two air chambers. Compressed air
moves the piston (4) to and fro in the cylinder (3).
When the piston reaches one end of the cylinder,
the piston switches the switchover valve (2). The
switchover valve (2) causes the control unit (1) to
change the supply of motor air from one side of the
piston to the other. The piston moves in the oppo-
site direction.
3.3 Fluid part
Fig. 4: Fluid part operation
At the time of the upward stroke, the non-return
valve in the piston (3) closes and pumps the mate-
rial in the top piston chamber (2) into the pressure
line through the material outlet (1). At the same
time, the non-return valve on the material inlet (5)
opens and sucks materials into the lower piston
chamber (4). The initial material pressure in the
material input (6) supports the suction process.
At the time of the downward stroke, the non-return
valve in the piston (3) opens and the non-return
valve (5) at the material intake closes. The material
in the lower piston chamber (4) is pumped into the
pressure line by the piston to the material outlet
(1).
