If compressed air is supplied to the rinsing water unit 190 via the compressed air connection 191, this compressed air flows into a compressed air space 199 and pushes the compressed air down the piston 196, thereby pressing the rinse water in a rinsing water space 198 through the rinsing water outlet opening 193, whereby the rinsing process is carried out ,
  • the actuating finger 161 Upon further lowering of the actuating finger 161 in the course of ventilation of the actuating coupling unit 150 via the nozzle 152, the actuating finger on the one hand releases the actuating lever 132, whereby the valve 133 returns to the closed position by gravity and / or spring projection. Following this, the actuating finger 161 triggers a further actuating lever 137, which opens a ventilation valve 138. As a result, the waste water valve control port 136 and the purge valve control port 135 are vented to ambient pressure, and the vacuum collapses at that point. By this release of the negative pressure, the Abwasserabsaugvorgang is terminated within the Abiganabsaugvortechnisch.

  • a baffle 187 which is inserted in a line section 186a between the compressed air valve body 182 and the quick exhaust valve 185, allows a reduction of the overpressure in the line section 186a. This creates a pressure difference between the conduit section 186a and a conduit section 186b extending from the quick exhaust valve 185 to the compressed air port 191.
  • This compressed air difference causes a changeover of the quick exhaust valve, whereby the line section 186b via a vent opening 188 on the Quick exhaust valve is vented.
  • This venting causes a rapid pressure reduction within the line section 186b and the rinse water unit 190 and thus terminates the rinsing process. After venting a re-filling with rinse water from the rinse water tank 195 is possible. As a result of the size of the orifice 185, this can influence the amount of rinsing water that is released from the rinsing water unit during a rinsing process.
