PROBLEM TO BE SOLVED: To simplify a fluid control type pressure switching valve and improve a load bearing capacity thereof.SOLUTION: A valve closing body 14 is movable in accordance with a pressure difference between a pressure acting on a first piston surface 14.2 and a pressure acting on a second piston surface 14.3, against the force of an adjustment spring 16 arranged in a valve interior space 12, between a closed position where fluid connection between an inlet opening 12.6 and an outlet opening 12.7 is interrupted and an open position where the fluid connection between the inlet opening and the outlet opening is opened. The first piston surface delimits, by the valve interior space, a first control chamber 12.1 connected to the outlet opening via at least one compensating connection part 14.7. The second piston surface 14.3 delimits a second control chamber 12.2 separated from a valve chamber 12.3 by a separation wall 18. The second control chamber is connected to a system pressure Pnp via a control connection part 12.5. |
