CURVILINEAR MOVEMENT DRIVE Russian patent published in 2020 - IPC F15B15/10 

FIELD: machine building.

SUBSTANCE: drive relates to machine building, robotics and can be used in pneumatic and hydraulic equipment. In the drive, including a rotary mechanism, consisting of an annular bellows, along the axis of which at the ends there are two plugs fixed, forming a sealed cavity, made with possibility of connection to the pressure device, flexible spring-loaded tie-rod is fixed on plugs on the bellows on the plugs, and on the plugs along the perimeter there is a limiter of their mutual axial movement, made in the form of flexible inextensible shell.

EFFECT: increased efficiency of drive of curvilinear movement by increase of power characteristics at preservation of its weight and size parameters and simplification of control.
