Abstract
The invention relates to a roto-reciprocating engine combining the reciprocating principle with rotary movement by using an orbiting non-rotating piston and sliding chamber seals to form positive displacement chambers distributed radially around the crankshaft.
Claims9
In an orbital engine,
- block means having a back wall, a front wall and a peripheral wall forming a cavity,
- the back wall having a crankshaft opening,
- the front wall having a clearance opening,
- piston means mounted for orbital movement in the chamber,
- sealing means connected to the piston means and forming a plurality of chambers with the piston means and the back, front and peripheral walls,
- a crankshaft connected to the piston means and extending through the crankshaft opening,
- the piston means being movable in the cavity in a predetermined orbit and covering the clearance opening throughout the orbit,
- an orientation member keyed to the piston means and extending from the piston means into the clearance opening,
- and guide means mounted movably on the block means and positioned exteriorly of the block means and keyed to the orientation member,
- the guide means permitting free orbital movement of the piston means and preventing rotation thereof relative to the block means.

In a two-cycle orbital engine,
- block means having a cavity,
- piston means orbital in the cavity,
- orientation means preventing rotation of the piston means in the cavity,
- sealing means forming with the block means and the piston means a plurality of crossed pairs of opposed chambers,
- one chamber of each pair being a firing chamber and the other chamber of each pair being a crankcase chamber and being diametrically opposed to the firing chamber, each firing chamber including an exhaust port and an intake port opened by the piston means near the end of its power stroke relative to that chamber,
- means for supplying a combustible mixture to each crankcase chamber,
- each exhaust port being closed by the piston means during the early part of the compression stroke thereof,
- ignition means in each firing chamber,
- and crankshaft means connected to the piston means and driven thereby,
- the crankshaft means and the orientation means causing the piston means to move orbitally as the firing chambers are fired one after another.
