Definitions
- the pin 84 of the right valve part 72 acts on the right locking ball 50 and lifts it from its seat 48. Due to this displacement of the bushing 64, the sliding surface 68 moves to the right and opens a connection between the inlet chamber 28 and the collecting container 14 via flats 70 and the annular groove 23 , Inlet chamber 28, flats 70 and annular groove 23rd
