Rotary internal combustion engine

摘要

A rotary engine has a top housing with suction and exhaust ports and bottom housing arranged to receive a crank assembly and a cam assembly. The crank assembly has a crank plate rotatably placed above the bottom housing and a set of semi circular cranks provided at the top surface of the crank plate to travel along with the crank plate. The cranks are positioned opposite to each other and are aligned to the crank plate. A crank shaft arranged to pass through the top housing and bottom housing drive along with the crank plate. The cam assembly has a set of cams placed above the crank plate and arranged to pivot through pivot pins. The cams and the cranks revolve to form an eccentricity with the outer cavity ring and inner cavity ring. The outer cavity ring is provided to surround the crank above the crank plate and the inner cavity ring is placed inside the cranks such that upon rotation of the crank plate and the cranks, two variable volume outer chamber is formed in between the cranks and the outer cavity ring, and two variable volume inner chamber is formed in between the cranks and the inner cavity ring.

主权项

1. A rotary internal combustion engine, comprising:
a top housing constructed with a suction port and an exhaust port, and a bottom housing arranged to receive a crank assembly and a cam assembly such that the crank assembly and the cam assembly are assembled in between the top housing and the bottom housing; a crank rotatably placed above the bottom housing and a set of semi circular cranks provided at a top surface of the crank plate to travel along with the crank plate, wherein the set of semi circular cranks includes two semi circular cranks positioned opposite to each other and aligned to the crank plate and a crank shaft arranged to drive along with the crank plate; wherein the cam assembly has a set of cams, each having radius on four sides and an air path on its bottom, placed above the crank plate and arranged to pivot through pivot pins, such that the set of cams and the set of semi circular cranks revolve to form an eccentricity with an outer cavity ring and an inner cavity ring; the outer cavity ring is provided to surround the set of semi circular cranks above the crank plate and the inner cavity ring placed inside the set of semi circular cranks, wherein upon rotation of the crank plate and the set of semi circular cranks, two variable volume outer chambers are formed in between the set of semi circular cranks and the outer cavity ring, and two variable volume inner chambers are formed in between the set of semi circular cranks and the inner cavity ring, wherein a set of air guide paths are formed at the bottom of the crank plate and the set of semi circular cranks to communicate the two variable volume inner chambers and the two variable volume outer chambers.
