Title:
ROTARY ENGINE
Document Type and Number:
WIPO Patent Application WO/2016/123930
Kind Code:
A1
Abstract:
A rotary engine, comprising a housing having an inner cavity in the shape of a figure of eight, and a casing inner cavity device main rotary shaft (35) and auxiliary rotary shaft (48), the main rotary shaft (35) and the auxiliary rotary shaft (48) performing transmission via transmission gears (23, 24), the main rotary shaft (35) driving recessed main rolling wheels (31, 32) to rotate, the auxiliary rotary shaft (48) driving a first spacer ring (42) and a second spacer ring (43) to rotate, a second rolling wheel (41) being placed between the first spacer ring (42) and the second spacer ring (43), direct transmission not being possible between the second rolling wheel (41) and the auxiliary rotary shaft (48), the outer circle of the second rolling wheel (41) being tangential to the outer circle of the recessed main rolling wheels (31, 32), the recessed main rolling wheels (31, 32) driving the second rolling wheel (41) to rotate when rotating, a third rolling wheel (51) being mounted between the first spacer ring (42) and the second spacer ring (43) via a third shaft (55), the outer circle of the third rolling wheel (51) being tangential to the outer circle of the second rolling wheel (41) and cutting inside a cylinder inner cavity, the third rolling wheel (51) being driven around the second rolling wheel (41) by the first spacer ring (42) and the second spacer ring (43) to rotate in a rolling manner in the casing inner cavity, forming a variable capacitance cavity body with the synchronously rotating main rolling wheels (31, 32), and opening a ventilation port (a) in a timely manner during motion.
