<p>A pressure regulator (1) comprises a body having a gas inlet (3) for a gas having an inlet pressure, a gas outlet (5) for the gas having an outlet pressure lower than the inlet pressure and a passage (7) connecting the outlet to the inlet. A regulator piston (9) is arranged in the body to control the outlet pressure of the gas by moving closer to and further away from a pressure regulator seat (11), and a regulating elastic element (13) is arranged to bias the regulating piston in a direction away from the pressure regulator seat, against the force of gas at outlet pressure acting on the regulator piston in a direction towards the pressure regulator seat. The passage is fluidly connected to a floating piston (25), arranged to move in response to increased inlet pressure by compressing a stabilizing elastic element (27), such that an increase in the force of the gas under inlet pressure acting on the floating piston is matched by an increase in the force of the stabilizing elastic element acting on the floating piston. The stabilizing elastic element is connected to the regulating elastic element via a connection element (29) arranged so that the compression of the stabilizing elastic element results in a decompression of the regulating elastic element.</p> |
