WAVE STEPPER MOTOR WITH HYDRAULIC PNEUMATIC STRAINING SYSTEM Russian patent published in 2012 - IPC F16H1/00 F01C1/10 

FIELD: machine building.

SUBSTANCE: wave stepper motor has a fixed flexible wheel, spinning rigid wheel and straining system with pneumatic hydraulic directional valve. The pneumatic hydraulic directional valve is designed as a stationary outer thick-walled cylinder (3) with channels (5) and the inner rotating part of coaxial tube (1) of high pressure with radial tube branches (7), rigidly connected by their outer end holes to an average coaxial thin cylindrical shell (2), having a hole to drain the waste worked-out material into its low-pressure chamber. The number of radial tube branches and holes for drainage can be selected so that during one revolution of a thin-walled shell multiple sequential switching of the holes on the outer surface of the shell to holes (4) on the outer thick-walled cylinder took place.

EFFECT: invention enables to increase multiple angular velocity of a traveling wave of deformation of a flexible wheel and a rigid wheel with an output shaft.
