Title:
BLADE ROTARY ENGINE
Document Type and Number:
WIPO Patent Application WO/2021/114438
Kind Code:
A1
Abstract:
A blade rotary engine, constructed by a rotor (4), a housing (1, 2, 3), and a transmission shaft (5). Cavities constructed between the rotor (4) and the housing (1, 2, 3) are divided into air cylinders (72) and oil cylinders (71); eight blades (27, 28) are mounted on the rotor (4), and do stepwise rotation in the cavities of the housing (1, 2, 3) and follow revolution of the rotor (4); two adjacent bosses (27, 28) of the rotor (4) are divided into the air cylinders (72), namely, combustion chambers, by two adjacent blades (27, 28) and the housing (1, 2, 3); the same bosses are divided into the oil cylinders (71) by two adjacent blades (27, 28) and the housing (1, 2, 3). During operation, the volume of the air cylinders (72) and the oil cylinders (71) constructed by two adjacent blades (27, 28) and the housing (1, 2, 3) vary, the volume of the other air cylinders (72) and oil cylinders (71) vary accordingly, so that the volume of all cylinders changes to achieve four strokes; two oppositely provided air cylinders (72) and two oppositely provided oil cylinders (71) have respective identical strokes; the strokes are performed simultaneously; the air cylinders (72) do work for power, and the oil cylinders (71) are used for lubrication and cooling; expansion force is directly transferred to the transmission shaft (5) by means of the rotor (4) for rotation work-doing.
