Summary:PROBLEM TO BE SOLVED: To automatically make movement of a needle, which is reciprocated by energy supplied from the outside, in an idling state, when pressure in a combustion chamber generated by a sliding piston exceeds a certain value, in a gas sucking/exhausting machine. SOLUTION: A piston 12 for sucking/exhausting gas fitted in a compression chamber 18 is linked with the needle 14 reciprocated with energy supplied from the outside through an elastic body. When the pressure of the gas in the compression chamber generated by the piston 12 is rated pressure or less, the needle 14 is linked integrally with the piston 12. On the other hand, when the pressure of the gas in the compression chamber generated by the piston 12 is rated pressure or more, the transmission of the movement of the needle 14 to the piston 12 is stopped.
