Description

 Rocker rotary cylinder type variable displacement mechanism and rotary engine thereof

Technical field

 The present invention relates to an engine or a hydraulic motor, and more particularly to a rocker rotary cylinder type variable displacement mechanism and a rotary engine therefor. It belongs to the field of power machinery. Background technique

 The core parts and technical points of hydraulic motors, hydraulic pumps, compressors, and even internal combustion engines operating under high temperature, high speed and high pressure conditions are the variable displacement modes, seals and sections of the mechanism.

f]匕.

When the ordinary internal combustion engine is working, the piston makes a high-speed linear reciprocating motion in the cylinder, and completes four cycles of "intake, compression, combustion, and exhaust", and converts the linear motion of the piston into a rotary motion through the crank-link mechanism, and then outputs power. Cylinders, pistons, and crank-and-rod mechanisms provide problems that are complex, cumbersome, inefficient, energy intensive, and vibration-intensive. The "triangular rotor" engine that appeared in the early 1960s is characterized by a triangular rotor that divides the elliptical cylinder into three separate spaces, each of which completes four strokes of intake, compression, work, and exhaust. The inner ring gear centered on the center of the triangular rotor meshes with the gear centered on the output shaft, and directly converts the expansion thrust generated by the combustion of the air-fuel mixture into the rotational power of the eccentric rotor. Compared with the crank-and-rod piston engine, the design of the triangular rotor engine has changed the heart of the engine, eliminating the need for connecting rods, crankshafts, valve mechanisms, etc. The structure is compact, lightweight, material-saving, and more importantly There is no high-speed inertial impact force on the upper and lower sides of the conventional engine piston, and the expansion force is directly converted into the rotational force, so that the operation is stable, the vibration is small, and the noise is low. However, it still has the following disadvantages: First, it consumes a lot of fuel. Cause The elliptical shape of the triangular rotor engine combustion chamber is not conducive to complete combustion, the flame propagation path is long, the combustion is incomplete, and the fuel and oil consumption are increased, which is not conducive to energy conservation and environmental protection. Second, the sealing performance is poor. The sealing member of the triangular rotor is at the top of the three corners, and its support and power output are realized by a pair of internally meshed gears. The eccentric structure and the wear of the gear meshing surface tend to cause the gap to gradually increase. Changing the relative position of moving parts, as the use time is extended, the decline in sealing performance will seriously affect the performance and service life of the engine.
