Rotary engine with vanes rotatable by compressed gas injected thereon

A rotary engine comprising:

• a) an outer shell comprising:
• an accommodating space,
• at least one exhaust port in fluid communication with said accommodating space, and
• a plurality of working spaces spaced apart from each other and arranged in a circumferential direction of said outer shell, said working spaces being in fluid communication with said accommodating space;
• b) a rotor disposed rotatably in said accommodating space in said outer shell comprising:
• a rotor body,
• a plurality of vanes extending outwardly from said rotor body and arranged in said circumferential direction of said outer shell, wherein each of said vanes includes a pushing end distal from said rotor body,
• two side plates disposed respectively and fixedly on two opposite sides of said rotor body such that said vanes are disposed between said side plates,
• a plurality of first exhaust passages each formed in an outer surface of said rotor body and disposed between two corresponding adjacent ones of said vanes, and
• a plurality of second exhaust passages in fluid communication with said first exhaust passages form in each of said side plates, respectively;
• c) a power output shaft rotatable in said outer shell and co-rotatable with said rotor body of said rotor such that said rotor rotates about a central axis of said power output shaft;
• d) a plurality of power-generating units disposed respectively within said working spaces in said outer shell, each of said power-generating units comprising:
• a swinging member connected pivotally to said outer shell,
• a divider disposed pivotally on said swinging member for dividing said corresponding one of said working spaces in said outer shell into an intake chamber and a compression chamber,
• a stop member connected pivotally to said outer shell such that said stop member and said swinging member are rotatable about an axis,
• a positioning rod having two opposite ends connected respectively and pivotally to said divider and said outer shell,
• a first one-way valve disposed within said divider for limiting flow of air from said intake chamber into said compression chamber,
• a first resilient member disposed between said swinging member and said outer shell for biasing said swinging member to pivot toward said rotor,
• a second resilient member disposed between said divider and said swinging member for biasing said divider to pivot away from said swinging member and toward said outer shell, and
• a third resilient member disposed between said stop member and said outer shell for biasing said stop member to pivot toward said rotor,
• wherein each of said swinging members comprises:
• a curved wall in contact with said pushing end of a corresponding one of said vanes of said rotor, and
• two hollow sidewalls extending respectively from two opposite sides of said curved wall into a corresponding one of said working spaces in said outer shell,
• wherein said curved wall comprises a first pivot end connected pivotally to said outer shell, and
• a second pivot end opposite to said first pivot end, wherein said divider comprises:
• a first pivot portion connected pivotally to said second pivot end of said swinging member, and
• a second pivot portion opposite to said first pivot portion and connected pivotally to said positioning rod,
• wherein said stop member comprises:
• two link sections disposed respectively within said sidewalls of said swinging member and connected pivotally to said outer shell,
• a stop section interconnecting said link sections and in slidable contact with said sidewalls of said swinging member, and
• an abutment section extending from said stop section toward said first pivot end of said swinging member and having a through hole formed therethrough,
• wherein said intake chamber is defined among said divider, said curved wall, and one of said sidewalls of said swinging member, and
• wherein said compression chamber is defined among said divider, said stop member, and the other of said sidewalls;
• e) a plurality of intake units corresponding respectively to said power-generating units, wherein each of said intake units comprises:
• an intake port formed in said outer shell and in fluid communication with a corresponding one of said intake chambers, and
• a second one-way valve disposed within said intake port for limiting flow of air from said intake port into said intake chamber;
• and
• f) a plurality of ignition units corresponding respectively to said power-generating units, wherein each of said ignition units comprises:
• a fuel injection hole formed in said outer shell and in fluid communication with a corresponding one of said compression chambers,
• a mounting hole formed in said outer shell and in fluid communication with said corresponding one of said compression chambers,
• a fuel-injecting nozzle disposed within said fuel injection hole, and
• a spark plug disposed within said mounting hole.
