Title:
ROTARY PISTON ENGINE
Document Type and Number:
WIPO Patent Application WO/2021/017124
Kind Code:
A1
Abstract:
A rotary piston engine, comprising a housing and a rotor (11). The rotating rotor (11) is disposed inside the housing; the cavity of the rotor (11) is divided into a compression chamber (13) with a changing volume. The outer ring of the housing is provided with several combustion chambers (14) that can rotate around a main shaft (7) of the rotor (11), and any one of the combustion chambers (14) is communicated with the compression chamber (13). The combustion chambers (14) are in transmission connection with the main shaft (7) via a transmission system, and the combustion chambers (14) drive the main shaft (7) to rotate by means of the combustion of compressed gas. The housing comprises an upper cylinder head (8) and a lower cylinder head (9), and a boss (12) of the upper cylinder head (8) is matched with the seam allowance of the lower cylinder head (9). A rotatable piston wheel gear (10) is provided between the upper cylinder head ( 8) and the lower cylinder head (9); evenly distributed support blocks (37) are arranged on the inner ring of the piston wheel gear (10), and the support blocks (37) are in contact with the rolling pair of the boss (12). Cavities enclosed by the boss (12), the lower cylinder head (9) and two adjacent support blocks (37) are combustion chambers (14). The rotary piston engine overcomes the shortcoming of long and narrow combustion chambers in traditional Wankel triangle rotor engine by means of rotating combustion chambers (14), and improves the combustion efficiency of the engine.
