Abstract
A pressure regulator comprises a housing (1) defining first and second chambers separated by a movable partition (4,5), the first chamber being provided with an inlet port (2) facing towards and sealingly closeable by a rigid central portion (5) of the partition at a position remote from its centroid and an outlet port (3), and the second chamber being vented (7) to a reference pressure, the regulator including means (8) extending between the housing and the central portion (5) of the partition to define a pivot axis for the partition extending between its centroid and the position of the inlet port (2). The partition (4,5) may be a tilting diaphragm or a piston (D) with a peripheral sealing element (S). The pivot axis for the partition may be defined by a fixed pivot pin (20), or by projections (8) extending across the first chamber to abut the partition (4,5). A two-stage device is also described in which the tilting partition (35) controls a pilot jet (32) which in turn controls a valve member (43) adapted to permit or deny access from a supply port (44) to an outlet port (33).
