Beschreibung
Zusammenfassung:	The utility model discloses a gas path pressure control assembly which comprises a compressor, a gas tank, a first control valve, a second control valve and a pressure adjusting piece, the gas outlet end of the compressor is communicated with the input end of the gas tank through a first gas path, and the gas inlet end of the compressor is communicated with the input end of the gas tank through a second gas path. The output end of the gas tank is communicated with a device to be supplied with pressure through a third gas path; the compressor is used for pressurizing and vacuumizing the gas tank; the first control valve is arranged on the first gas path and used for controlling the on-off state of the first gas path and the communication state of the compressor and the atmosphere; the second control valve is arranged on the second gas path and used for controlling the on-off state of the second gas path and the communication state of the compressor and the atmosphere; and the pressure adjusting part is arrange
