Pump
The wobble disc is mounted directly on the gear shaft and yields at maximum pres su re and water quantity
approx. 1725 rpm. By doing so it delivers approx. 19 (16 *) l/min. through the suction valve, the pres su re
valve and the piston of the by-pass valve, where two through-ho les make the necessary pres su re drop
to keep the valve cone closed.
When water fl ow is interrupted, pres su re rises, until the safety valve opens. Because of the achieved
pres su re drop the valve cone is pressed to open, so that the water recirculates at a pres su re < 10 bar.
Quantity of water is regulated by means of a screw pressing the cone to let some of the water recircu-
late.
