ROTARY DRIVE SYSTEM FOR DOOR MOVEMENT WITH ORIENTABLE LEAVES, IN PARTICULAR, IN VEHICLES Russian patent published in 2017 - IPC E05F15/54 

FIELD: transportation.

SUBSTANCE: rotary drive system (1) defines the rotation axis (3) and comprises a stator shaft (4), an outer housing (5), an annular piston (7) of the fluid dynamics driver (8) and a tubular rotor (10) of the screw transmission (11). The rotor (10) is interlocked with the linear guide element (15) by means of one or more second rolling elements (14). Driver (8) is made as a double-acting driver. The pressure chamber (9) is divided by a piston (7) into the first pressure chamber (9A) and the second pressure chamber (9B) located on opposite sides of the piston (7). The stator shaft (4) directly defines the part of both the first and second pressure chambers (9A, 9B). The rotor (10), the linear guide element (15) and the first and second rolling elements (12, 14) are located inside the annular pressure chamber (9).

EFFECT: creation of an energy efficient rotary drive system with a simplified and robust design and the possibility of using an external housing as a rotary column.
