DESCRIPTION:

BRIEF SUMMARY
The present invention relates primarily to an internal combustion rotary engine but also to a pump or compressor.
Internal combustion engines of various forms have been known and proposed over the years and are generally in the form of a reciprocating piston engine or a rotary piston (sometimes referred to as a Wankel) engine. Other known forms of engine include jet turbine engines, but each of these generally known designs has one or more of a number of different problems or limitations. For instance in a reciprocating piston driven crankshaft the drive imparted to the crankshaft by the connecting rod and piston occurs at a relatively small radius from the center of rotation of the crankshaft (which thereby controls the stroke of that same piston and subsequently the maximum rotational speed of the engine) and thus the torque generated is also relatively small. That torque also varies in magnitude according to the angular displacement of the crankshaft. Moreover reciprocating piston engines require relatively large flywheels to "smooth out" the extreme variations in torque and maintain the momentum of the crankshaft. Rotary piston engines on the other hand have similar torque due to the piston force being applied at a relatively small radius, and suffer particularly from sealing problems at the tips of the rotors and high fuel consumption. Since power output is directly related to the product of torque and rotational speed, increasing the magnitude of both will increase the output power. Turbine engines tend to be complex and the delivery characteristics of their power is not suited to applications such as vehicles or portable power tools.
It is an object of the present invention to avoid or minimize one or more of the foregoing disadvantages.
According to a first aspect of the present invention there is provided an internal combustion engine comprising an inner stator and an annular rotor arranged to rotate around the stator, the stator comprising: combustible fluid into the or each chamber; and chamber, formed and arranged so as to provide a pathway for conducting combustion products from said chamber into driving engagement with the turbine reaction means so as to cause the rotor to rotate around the stator.
In a preferred embodiment of the present invention the rotor comprises angularly distributed induction, compression and exhaust sectors which communicate in turn with said at least one combustion chamber, the induction sector being coupled to a fuel inlet for communicating fuel to the combustion chamber via a chamber opening, the compression sector comprising a wall for sealably engaging said chamber opening to confine fuel within the chamber, and the exhaust sector providing said turbine reaction means which are arranged to be exposed to said combustion products.
According to a second aspect of the present invention there is provided a rotary engine having induction, compression, and combustion and exhaust phases and comprising an annular rotor having angularly distributed induction, compresssion and exhaust portions, said annular rotor being mounted for rotation around a stator, said induction portion having fluid inlet means, said compression portion having wall and seal means for confining compressed combustible fluid within a restricted volume between said rotor and stator, said exhaust portion having reaction means, conveniently in the form of turbine means, and formed and arranged for driven engagement with combustion products from the combustion and exhaust phase so as to drive said rotor around said stator, said stator having a transversely extending chamber with a piston means reciprocably slidable therein for movement from a first retracted position to a second extended position for compressing fluid admitted to said chamber through said induction portion of said annular rotor, against the compression portion of said annular rotor; drive means formed and arranged for driving said piston means between said first and second positions so as to provide retraction of the piston means during t
