Definitions

  • I provide a generally cylindrical rotor which is rotatable within a complementary cylindrical inner surface of a housing.
  • Recesses or cavities are formed in each quadrant of the rotor and in each cavity, a compression arm is pivoted on an axis near the periphery of the rotor to swing from a compressing position, wherein it is disposed along the periphery of the rotor, to an expanded position wherein it is displaced radially inward from the periphery, moving along an arcuate wall of the cavity, which has its pivotal axis as its center of rotation.
  • Cam followers on the arm engage in a generally oval track on the housing so that there are two complete oscillations or four cycles of operation during each revolution of the rotor.
  • the rotary engine or compressor 10 of this invention including an outer stator or housing 12, which may be mounted on suitable supports 13 and which has an inner cylindrical surface 14. Carried on a shaft 16 which is rotatably mounted between sidewalls 18 of the housing 12 is a rotor 20, which in operation rotates in the direction of the arrow R.
  • the rotor is of generally cruciform configuration with four radial spokes or arms 22 having complementary . cylindrical outer surfaces 23.
  • pivotal axes 24 Adjacent each pivotal axis is a compression cavity 26 having a generally radial wall 28 and an arcuate wall 30 formed on an arc 30 about each pivotal axis 24.
  • a compression arm 34 Pivotally carried on suitable pins 32 to pivot about each axis 24 is a compression arm 34 having a working outer side surface 36 which forms a continuation of the periphery 23 of the rotor 20 and a slide surface 38 complementary with the arcuate surface 30 of the cavity 26.
  • a cam track 40 of generally oval configuration is routed or otherwise formed in the housing side walls 18 (only one being shown) and cam follower rollers 42 is carried on each of the compression arms 34. Because of the generally oval configuration of the track 40, the cam followers 42 cause each compression arm 34 to make two complete oscillations, or four strokes, during each revolution of the rotor within the housing or stator 12.
  • Suitable seal means 44 may be provided on the slide surface 38 and sides of the compression arms 34 to prevent blow by of gases during such oscillating movements.
  • seal means 46 are provided on the periphery of the rotor 20 so that each cavity 26 is an isolated gas chamber.
  • Gas intake ports 48 are provided in the stator 12, as are gas exhaust ports 49.
  • a compression chamber or cavity 26 moves from the position shown at 26A to that shown at 26B, during rotation in the direction R it uncovers the gas inlet ports 48 while the compression arm 34 is withdrawn inward to its fully retracted position, drawing a full charge of gas into the chamber 26. Then, as it moves toward the position shown at 26C, the inlet ports 48 are sealed off by seal members 46, and the arm 34 oscillates outward to the full compression position shown at 26C, at which time the outer working surface 36 of the compression arm 34 forms a virtual continuation of the periphery 23 of the rotor 22. At this point, ignition occurs and, in the case of a gasoline engine, a suitable spark plug 50 is provided for ignition.
  • a cavity 52 may be provided in the outer surface 36 of the compression arm 34 to serve as an ignition chamber.
  • the compression arm 34 Upon ignition, the compression arm 34 is driven radially inward toward the position shown in 26D. This drives its cam follower toward the minor axis of the oval cam track 40, rotating the rotor 20 to deliver power to the main shaft 16,which in turn, may drive a power shaft or other suitable power take-off (not shown).
  • the arm 34 swings back out to the position shown at 26A, during which time it passes the exhaust ports through which the combusted gases are exhausted.
  • the spark plug 50 may, of course, be omitted so that ignition occurs by heat of expansion.
  • outlet ports may be provided at position 26C in place of the spark plug 50, and additional inlet ports 48 may be provided at position 26D.
