LOOP MACHINE (VERSIONS) Russian patent published in 2011 - IPC F01C3/00 F01C19/10 

FIELD: machine building.

SUBSTANCE: loop machine consists of stator, rotor and pistons. The loop machine is designed for reversible transformation of pressure energy of working medium into rotation of working member due to reciprocal rotation and elements motion at their interaction and due to movement of piston relative to rotor along twisted trajectory. Volume of working medium enclosed between any pistons at their motion can change. Working surface of the stator is formed with radial rotation of a border of part of rotation surface on main axis with centre on surface of rotation on circular axis and with not less, than one circular recess formed in working surface of rotation surface. The rotor is installed in working surface of the stator and can rotate. It has not less, than one loop working cavity twisted around circular axis. The loop working cavity is designed for possible movement at possible rotation of not less, than one piston with packing. Further, the rotor is designed to slide with a support along the circular recess of the stator on side of piston surface. The rotor is divided with at least one recess concentric to main axis forming not less, than one packed (pressurised) cylinder with working surface of the stator. The force of packing hold-down force in each piston and/or its part can be changed when piston travels and rotates.

EFFECT: design of loop machine.
