VOLUMETRIC TYPE ROTARY MACHINE Russian patent published in 2019 - IPC F01C1/08 F01C1/24 F01C1/20 F02B53/04 

FIELD: machine building.

SUBSTANCE: invention relates to power and transport machine building and can be used for drive of mechanical energy consumers, as well as a component of internal combustion engine, including gas turbine engines. Essence of the invention consists in that the volumetric type machine comprises housing (1), at least one working medium feed/discharge channel (8) and spacer wheel (5) with process recess (6), central body installed in inner cavity of housing with possibility of rotation around its axis and with clearance relative to housing wall with formation of annular working (9) channel, shaped element covering supply channel, projection (18) and blade (4). It is equipped with central stationary header (7) with at least one longitudinal window (16). Rotor (2) is made with annular heating chamber (3) limited by outer (12) shell with longitudinal opening (13) and inner (14) shell with longitudinal slot (15). Heating chamber (3) is communicated with opening (13) and working medium feed / discharge channel (8), wherein profiled element is made on inner (14) shell of rotor (2) with possibility of overlapping longitudinal window (16), separating wheel (5) is installed in inner cavity of housing between wall of housing and rotor (2), blade (4) and projection (18) are made on outer (12) shell of rotor (2). Surface of process recess (6) of spacer wheel (5) is conjugated with mating surface of projection (18).

EFFECT: high efficiency, improved specific weight and overall dimensions.
