ABSTRACT:
This invention relates to supply circuits for fluids under pressure, particularly gases. Such circuits ordinarily comprise a main pipe between a source of fluid and a point of consumption, and to which main pipe is fitted a regulator and pressure-reducer and at least one obturator is normally fitted to this main pipe downstream of the regulator and pressure-reducer. In such an arrangement, the present invention provides means for minimising over-pressures consequent on the said obturator closing which are caused by the inertia of the regulator, which means is fitted as a by-pass to the main pipe on either side of the regulator and pressure-reducer. In one preferred embodiment, this means comprises a venturi and a reservoir which is connected by a first pipe means to the venturi and wherein the venturi is fitted to a second pipe means as a by-pass to the regulator and pressure-reducer, a valve being provided in the second pipe means upstream of the venturi.
