DOUBLE-ACTION COMPRESSION-VACUUM IMPACT MACHINE Russian patent published in 2017 - IPC B25D9/08 B25D9/26 

FIELD: machine engineering.

SUBSTANCE: machine has a body and a striker placed therein forming an upper chamber and a lower chamber connected with atmosphere, a vacuum-compressor installed in the upper part of the disc body forming chambers above and below the disc, a receiver is connected to the upper chamber, a magnetic lock for the striker is installed in the upper chamber, and a working tool. The chamber above the disc is permanently connected with atmosphere, and the vacuum-compressor is connected through a switch to a current source. The vacuum-compressor is a centrifugal compression-vacuum mechanism connected to a working medium distributor, which faces with a suction hole into the chamber under the disc, a cut from the upper chamber by a solid partition, and an exhaust hole into the chamber above the disc. The working medium distributor is arranged with for periodic connection of the chamber under disc with the upper chamber or the atmosphere, and the chambers above the disc with the upper chamber.

EFFECT: increased efficiency of machine operation and its reliability, simplified its structure.
