Abstract

An I.C. engine of the rotary- abutment type has an annular chamber defined by a main rotor 2 and housing walls 11, 12, 20 and accommodating vanes 14, 15 fixed to the rotor, the chamber being intersected by a gate rotor(s) 3, 4, which is (are) rotated synchronously with the main rotor by an output shaft 5 through gears 6, 7, 8. Ignition in a combustion chamber 16 is initiated by a sparking plug 17. <IMAGE>

Description

SPECIFICATION A Rotary Piston Internal Combustion Engine This invention relates to a rotary-piston internal combustion engine.
Such engines are well known and depend for the function on complex torridle shaped central rotors rotating on eccentric gears to compress and explode combustable gases. These prior art engines have peculiar sealing problems and their overall efficies are low.
According to the present invention there is provided a rotary internal combustion engine comprising; a housing with inlet and exhaust ports, a rotor rotatable in the housing and together therewith defining an annular chamber which communicates with the ports, a rotary piston having a plurality of vanes, communicating with the annular chamber, at least one rotary valve situated in the housing so as to intersect the annular chamber such that the annular chamber is divided into induction, compression, expansion and exhaust zones, the, or each valve having at least one opening therein to permit periodic passage of a vane when the piston revolves, a power output device rotatable by the rotary piston, and a means for rotating the central rotor and rotary valve or valves in response to rotation of the rotary piston such that the combustion chambers are periodically and successively closed off by a vane.
Also, according to this invention, there is provided a means of transporting fluid and thereby doing work upon it. The fluid being induced and exhausted through two or more parts contained within a housing and together with a rotatable piston or pistons defining an annular chamber which communicates with the ports, a rotary piston with at least one radial vane revolvable around the central rotor in the annular chamber, at least two rotary valves in the housing so as to intersect the annular chamber and abut the central rotor such that the annular chamber is divided into chambers for the fluid to flow through, each rotor valve having at least one opening to allow periodic passage of a vane when the piston revolves, a shaft connecting the rotary piston to a prime mover and a means of coordinating and controlling the rotary piston and rotary valves in a unified manner.
This invention will now be described by way of example with reference to the accompanying drawings, in which: Fig. 1 is a cross-section through the engine according to the invention, on a line A-A of Figure 2.
Fig. 2 is a cross-section on the line B-B of Figure 1.
Figs. 3 and 4 demonstrate the action of the engine.
With reference to Figs. 1 and 2, the engine has a housing 1, a rotary piston 2, two rotary valves 3, 4, a shaft 5, a means of co-ordinating the rotary valves and piston vanes 6, 7, 8, an end plate 9, and cover 10.
The rotary piston 2 is constrained to move in an annular groove, the walls of which are 11, 12 and 20, by the shaft bearing 13. Slots are cut in both rotary valves 3, 4, in such a way as to allow the 2 vanes 14 and 15 to pass. The gear wheel 7 is connected via shaft 5 to the rotary piston 2.
Two additional gears are provided which connect the shaft to the two rotary valves 3, 4, and increase the speed of the valves above that of the shaft. A combustion chamber 1 6 is provided so that the compressed gas can be exploded by the spark plug 1 7. Each rotary valve rotates around a central piece 1 8 and 1 9 which is affixed to cover 9.
As the vanes rotate, charge is induced into the zone defined by 22, (Fig. 3) previously induced charge is being compressed in zone 23, ignited charge is expanding in zone 24 and exhausted charge is being expelied through port 21. Fig. 4, demonstrates the way in which charge is transferred from the forward part of the vane to the reverse part previous to ignition.
