Druckempfindliches Ventil

摘要

A pressure sensitive valve (10) comprises a valve body (12) defining a bore (14), an inlet port (16) and an outlet port (18). The inlet port (16) is in fluid communication with the outlet port (18) when the valve (10) is open and defines a fluid flow path (20). The fluid flow path (20) is in communication with the bore (14). A reverse buckling member (22) extends at least partially across the bore (14), the member (22) being adapted to reverse its conformation when a set pressure has been exceeded. The valve (10) includes means for actuating inversion of the reverse buckling member (22) when the set pressure has been exceeded. The valve (10) also includes means for sealing the reverse buckling member (22) from the fluid flow path (20).
