Abstract
Abstract This invention provides an internal combustion engine, specifically a rotary engine, operable either by compression ignition or spark ignition and having an engine rotor with means for introducing combustible fuel to the rotor and means for exhausting burnt gases from the rotor, the rotor having at least one track for the travel therein of a free piston member, a free piston member in said track, and at least one reaction member operatively mounted in relation to the rotor so as to resist the application to the engine rotor of torque applied in a reverse direction upon the explosion of combustible gases within the rotor, the free piston member being operable upon such explosion of combustible gases to travel in said track to induce in the rotor an engine torque in the forward direction.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
115 words
An internal combustion engine comprising an engine rotor having at least one track for the travel therein of a free piston member, means for introducing combustible fuel to the track, means for exhausting burnt gases from the track, a free piston member in said track, and at least one reaction member operatively mounted in relation to the rotor in such manner as to resist the application to the engine rotor of torque applied in a reverse direction upon the explosion of combustible gases within the rotor, the free piston member being operable upon such explosion of combustible gases to travel in said track to induce in the rotor an engine torque in the forward direction.
Claim 2
Dependent Claim
115 words
An internal combustion engine comprising an engine rotor having at least one track for the travel therein of a free piston member, means for introducing combustible fuel to the track, means for exhausting burnt gases from the track, a free piston member in said track, and at least one reaction member operatively mounted in relation to the rotor in such manner as to resist the application to the engine rotor of torque applied in a reverse direction upon the explosion of combustible gases within the rotor, the free piston member being operable upon such explosion of combustible gases to travel in said track to induce in the rotor an engine torque in the forward direction.
Claim 3
Dependent Claim
49 words
An internal combustion engine according to claim 1 wherein the track is of substantially S-shape, having a middle part which passes through the axis of rotation of the engine rotor and is curved at its opposite ends in opposite directions, and outer end parts which extend in opposite directions.
Claim 4
Dependent Claim
27 words
An internal combustion engine according to claim 2 wherein the outer end parts are substantially tangential to the direction of rotation of the rotor and substantially parallel.
Claim 5
Dependent Claim
24 words
An internal combustion engine according to claim 1 wherein there is a reaction member in each of the opposite end parts of the track.
Claim 6
Dependent Claim
62 words
An internal combustion engine according to claim 4 wherein each reaction member is slidably mounted in an end of the track and is operatively connected through a one-way drive means to a frame member of the engine whereby the reaction from the explosion of gaseous fuel is transmitted to the engine frame for resisting the application to the rotor of negative torque.
Claim 7
Dependent Claim
33 words
An internal combustion engine according to claim 1 wherein said one reaction member has gas inlet valve means arranged to permit the inlet of a combustible gas to the interior of the track.
Claim 8
Dependent Claim
39 words
An internal combustion engine according to claim 1 wherein the means for introducing combustible fuel to the rotor include at least one fuel supply line for conveying fuel to the track at the location of said one reaction member.
Claim 9
Dependent Claim
60 words
An internal combustion engine according to claim 1 wherein there are means for applying to said one reaction member a pressure to move said reaction member forwardly relative to the rotor in the direction of rotation of the rotor to an operative position in the track after its displacement from such operative position on the explosion of the gaseous fuel.
Claim 10
Dependent Claim
35 words
An internal combustion engine aCcording to claim 8 wherein the means for applying pressure to said one reaction member include a tube for conveying exhaust gas under pressure to the outer end of the track.
Claim 11
Dependent Claim
25 words
An internal combustion engine according to claim 1 wherein the free piston member is of spherical shape and the track is circular in cross section.
