Abstract

The automatic control valve for fluid in a passage comprises a housing with a fluid inlet (2) and output (3). A valve seat (4) is formed in the housing to divides the housing into first (1a) and second (1b) chambers and a valve closure (11, 8a) selectively engages with the seat. A pressure chamber (5) connects to the housing and a through passage (12) produces a constant fluid connection between the pressure chamber and the second chamber (1b). An operating rod (8) runs between the pressure chamber (5) and the valve part. If the pressure inside the second chamber exceeds normal levels a spring (6) moves the valve sway from the seat.
