CN201347910Y - Gas-saving type gas supercharger compressed in high pressure and aspirated in low pressure - Google Patents

Abstract

The utility model belongs to the technical field of gas supercharging devices, in particular to a gas supercharger which can obtain high pressure gas by using low pressure gas as the driving force, and save the consumption amount of driving gas. The supercharger can be integrated into a whole by a pressure relief valve group consisting of a pressure relief valve and a one-way valve with a change-over valve, and is connected with a gas supply inlet of a driving cavity with a rod, thus gas can be firstly decompressed after flowing into the pressure relief valve, and then flows into the driving cavity with a rod, thereby supplying different driving gas for two driving cavities. The gas-saving type supercharger has the beneficial effects of supplying total pressure driving gas for a driving cavity without a rod and supplying low pressure driving gas for the driving cavity with a rod, thereby saving the driving gas consumption amount compared with that the two driving cavities are supplied with driving gas with the same pressure.
