The pressure regulator comprises a flat, flexible diaphragm (6) mounted between two half casings (1, 2) and disposed normal to the axes of the inlet (3) and the outlet (4), which is offered flush on one side to a substantially flat ring (20) associated with the first half casing (1) at the innermost end of the relative port (1a), affording a plurality of uniformly distributed slots (10) exposed or stopped by the diaphragm (6) and combining with the first half casing (1) to create a first chamber (21) beyond the port (1a); the diaphragm (6) is held in place from the opposite side by a plate (9) seated in the second half casing (2) at the innermost end of the relative port (2a) and combining with the half casing (2) to create a second chamber (22) facing the first chamber (21). The first port (1a), the slots (10), the two chambers (21, 22) and the second port (2a) combine to provide a passage through which the gas is able to bypass the diaphragm (6) when separated from the ring (20). <IMAGE> |
