<p>Rotary motion drive, which comprises rotor's housing (1), in which there are a cylindrical rotor's area (2) with inlet port and exhaust port. Two pairs of rotors which are rotatably mounted in the cylindrical rotor's area (2). Each rotor has a rotor's shaft (6, 7), which are fastened to two pairs of vanes (8, 9) and (10, 11). The cylindrical rotor's area (2) is divided by the neighbouring vanes to four working chambers (48), which are alternately expanded and then contracted. There is an output shaft (15) which is connected with rotor's shaft (6) and rotor's shaft (7) by at least two oval gears. Precisely, one oval gear (16) is fastened on the rotor's shaft (6). The other oval gear (18) is fastened on the rotor's shaft (7). Two oval gears (17, 19) are fastened on the output shaft (15). These oval gears (17, 19) are positioned 90° out of phase on the output shaft (15). The oval gear (16) is connected with the oval gear (17). The oval gear (18) is connected with the oval gear (19). These connections can be direct or an additional oval gear can be inserted.</p> |
