ROTARY MACHINE Russian patent published in 2004 - IPC

FIELD: power engineering.

SUBSTANCE: invention can be used in hydraulic and pneumatic drives of different devices. Proposed machine has cylindrical bushing arranged between cylindrical surfaces of housing and rotor, installed concentrically on rotor for axial displacement and provided with longitudinal slots to pass blades. Said slots communicate with variable pressure source. Rotary machine has capacity control chamber formed by cylindrical surfaces of housing and rotor, end face of movable cylindrical bushing and end face cover of housing, and pressing chamber made in opposite end face cover of housing. Divider is installed for displacement along rotor axis into said pressing chamber and it has cavity on end face interacting with movable cylindrical bushing. Part of shaped curve of cam of cam mechanism, corresponding to TDC of tappet, is made with length of arc less than 180 degrees.

EFFECT: increased capacity, enlarged operating capabilities owing to possibility of control.
