Description of the pump
Fig. 1
The pump is a dry-running rotary vane compressor.
It consists of a housing (1), the eccentrically installed rotor (2), the radially movable vanes (3) and the inlet
and outlet (5+6).
When the rotor turns, gas flows through the intake filter (7) into the enlarging chamber (4) until it is shut off
by the next slide valve. The enclosed gas is then compressed until the relief valve (6) opens against atmo-
spheric pressure.

• are subject to the same legal and standardisation requirements,
• have a similar design,
