Abstract
Four adjacent parallel rotors of elliptical cross section have hollow interior flow passages communicating through hollow supporting shafts at one end. The supporting shafts at the opposite ends of the rotors have eccentric crank pins received in bearing holes in a common connecting block which orbits as the rotors rotate in unison. One of the shafts extends beyond the crank block as a drive shaft. Each rotor has a second flow passage opening through its surface adjacent to one apex of its major axis. A first pair of these flow passages, in diametrically opposed rotors, open in trailing relation to apices of the two rotors. The other pair of rotors has secondary flow passages through their surfaces in leasing relation to the apices of the latter two rotors.
Claims10
An internal combustion engine comprising a group of at least three elongated rotors having non-circular transverse cross sections and central shafts extensions on each end with the shaft extensions journalled in two end plates, at least two of said rotors having hollow interiors and one of the shaft extensions on each of said two hollow rotors forming an opening to the interior of their rotors,
- an outer body enclosing said group of rotors in spaced relation and closed on said end plates,
- means connecting the ends of the shaft extensions of said rotors exteriorly of an end plate for equal and simultaneous rotation,
- separator seals between adjacent rotors extending from end to end of the rotors and having enlarged beads on their inner edges,
- tension rods passing through said outer body from hook connections to said seals and tensioned to draw said beads against adjacent rotors,
- an outlet port formed through at least one of said hollow rotors in advance of the rotational direction of an apex of the rotor,
- an inlet port formed through another one of said hollow rotors in trailing relation to an apex of that rotor,
- and a fuel injector nozzle with an associated fuel pump projecting through one of said end plates to the space between said rotors.
An internal combustion engine comprising a group of four elongated rotors having elliptical cross section with hollow interiors and central shaft extensions on each end with the shaft extensions journalled in two end plates, with a tubular body enclosing said group of rotors between said end plates and spaced from said rotors, one of said shaft extensions being adapted at its outer end to be connected as a drive shaft,
- means interconnecting said shaft extensions for simultaneous rotation,
- a first opposed pair of said rotors defining intake ports through their sides in trailing relation to apices of their cross sectional axes,
- the other opposed pair of rotors defining outlet ports through their sides in leading relation to apices of their cross sectional case axes,
- inlet ducts formed through shaft extensions of said first pair of rotors,
- outlet ducts formed through shaft extensions of said other of said pair of rotors and opening exteriorly of said end plates,
- blower means connected to deliver air to said inlet ducts, fuel injection means connected to deliver to the space between said rotors,
- and separator seals extending from end to end of said rotors and therebetween fitted in sliding contact between adjacent rotors.
