Abstract
The utility model discloses a double-stage compressor with a middle venting partition board. The partition board and a partition board cover are arranged between a primary cylinder and a secondary cylinder. The lower surface of the partition board is closely attached to the top end of the primary cylinder. An annular middle-pressure cavity is reserved on the upper surface of the partition board. A primary venting through hole is reserved in a certain position of the middle-pressure cavity. The partition board cover covers the upper surface of the partition board. A secondary air inlet through hole communicated with the middle-pressure cavity is reserved in the partition board cover. A one-way valve from the primary cylinder to the secondary cylinder is arranged at the primary venting through hole. According to the double-stage compressor, the middle-pressure cavity with a certain volume is reserved on the partition board, so that a buffer space can be provided for a primarily-compressed gas and even an enthalpy-increasing gas; and by the one-way valve, a middle-pressure gas can be effectively controlled not to be sucked into the primary cylinder, so that double-stage compression efficiency is ensured, and the compressor is practical and reliable.
