A third and a fourth seat valve respectively comprise a shut-off component (72,76) acting against a respective valve seat (70,74), whereby with the shut-off component lifted from the third valve seat a primary pressure chamber (8) communicates with a secondary pressure chamber (12), and with the shut-off component lifted from the fourth valve seat the secondary pressure chamber communicates with a ventilation port (20).",
