COMPRESSOR AND VACUUM PUMP PROVIDED WITH TRANSMISSION Russian patent published in 2020 - IPC F04C29/12 

FIELD: machine building.

SUBSTANCE: group of inventions relates to a compressor and a vacuum pump provided with a transmission. Compressor (1) is provided with compressor element (2) with driven shaft (9) and engine (3) with drive shaft (13) to actuate element (2). Compressor (1) is additionally provided with transmission (4) between shaft (13) and shaft (9). Transmission (4) comprises housing (10) and at least driven gear wheel (11), which is installed on shaft (9), and driving gear wheel (14), which is installed on shaft (13). Housing (10) comprises two separated chambers (20, 22). First chamber (20), which is connected to shaft (9), and second chamber (22), which is separated from chamber (20). Chamber (20) is communicated via channel (21) with chamber (22). Around wheel (14) or wheel (11) chamber (22) is formed. Chamber shape (22) is such that when wheel (11, 14) rotates around this wheel (11, 14) gas flow is created, which leads to negative pressure in channel (21) under action of Venturi effect.

EFFECT: group of inventions is aimed at increasing efficiency of compressor and vacuum pump.
