METHOD AND DEVICE FOR LIQUID OR GASES INJECTION (VERSIONS) METHOD AND DEVICE FOR LIQUID OR GASES INJECTION Russian patent published in 2015 - IPC F04C2/344 F04C18/344 

FIELD: machine building.

SUBSTANCE: method for liquid or gases injection means successive suction, compression and ejection of the work medium inside the casing 1, ensured by means of the reciprocating movement of the work elements, this in ensured by the cylinders rotation around the centre of circle and own axis. The work medium movement is ensured via the holes due to alternative interaction of each hole with each of the work elements. The device for liquid or gases injection includes the installed in casing 1 fixed chuck plate 3 with radially installed cavities. The end parts of the cavities create a circle, and at least two work elements inside the cavities. On the chuck plate 3 the cylinders are installed they are provided with the work elements at equal distance from their centres, and at the end faces two covers with holes are located. Each hole is made with possibility of alternate interaction with each of the work elements.

EFFECT: increased efficiency of liquid or gas transfer under high pressures due to increased injected volume.
