Definitions

  • the upper cavity 41 is open (connected to an outlet 3) and its volume decreases, the fluid in the cavity 41 is therefore returned to the outlet 3.
  • the lower cavity 42 is open (connected to an inlet 2) and its volume increases, the fluid is therefore sucked from the inlet 2 towards the cavity 42.
