Abstract

The rotor (2), rotates in consequence of combustion and consequent expansion of gases, inserted in a cylinder (1). The rotor has cavities that, when turning, in conjunction with the opening and closing of valves (3 and 4), will forming chambers destined to generate the procedures of admission of gas, compression, combustion and exhaust. The rotor has cavities designed to house the intake and compression chambers (11) and different cavities intended to accommodate the combustion and exhaust chambers (9, 10), ie, the gases are admitted into a chamber and compressed, and transferred to another chamber, where combustion and exhaust occur. The passage of the gas already compressed, from the first to the second chamber is made through the opening (5) in the inner wall of the cylinder. In this opening are located the spark plugs (6) and/or the fuel injectors, depending on the fuel used.

Claims

AMENDED CLAIMS
received by the International Bureau on 04 August 2015 (04.08.2015).
1 - Internal combustion four-stroke engine, which has a rotor, with simultaneous operating chambers, with chambers exclusively intended for the intake and compression phases, and different chambers exclusively intended for the combustion and exhaust phases, characterized by:
a rotor (2) constituted by a single and undeformable piece, without any type of conduits with exception to the opening in the shaft of engine, that rotates always in the same direction in a concentric axis within a circular cylinder
(1) with inlet (7) and outlet (8) ports accommodated in opposed bases, having the rotor, cavities which are intended solely as intake and compression chambers (11) which has one sidewall that prevents that these chambers ever been exposed to the exhaust ports (8), and other different cavities interspersed with the firsts, are intended solely as a combustion (9) and outlet (10) chambers which, unlike the previous ones has a notch to seat the combustion/exhaust valves (4), and one sidewall that avoid the exposure to the inlet ports (7), wherein, to each intake/compression chamber (11) corresponds a combustion/exhaust chamber (9 and 10), wherein those both sidewalls are alternately disposed in one or at the other side, along all rotor, wherein on the side which has no sidewall, chambers are directly exposed to the inlet ports
(7) or exhaust ports (8), wherein the sidewalls or its inexistence, in combination with the valves, coordinates the admissions, the sealing to the ports (7 or 8) and the exhausts of chambers, and all these chambers are formed by the spaces created between the rotor, the circular cylinder and valves (3 and 4), and all the chambers formed are used to the exclusive and direct engine operation;
valves which route crosses the rotor path, are designed to prevent the passage of gases between different phases of the cycle of the engine in the same chamber of the rotor, wherein some valves are exclusively intended for the phases of intake and compression (3) and other valves are exclusively intended for the phases of combustion and exhaust (4), and each of them operates exclusively in the intake/compression chambers (11) or combustion/exhaust chambers (9 and 10), respectively, whereby;
the cylinder (1) houses one intake/compression valve (3), one combustion/exhaust valve (4), one cavity (5), one spark 11
(6), one inlet (7) and one outlet port (8) for each set of one intake/compression (11) and one combustion/exhaust chamber (9 and 10) of the rotor (2), wherein the cylinder houses the rotor and valves, contemplate spaces or openings for the operation thereof, and openings that allow the gas inlet (7), and the outlet of the exhaust (8), being these the unique ways which allow transferences of gases to the inside and from the inside to the exterior of the housing and wherein the cylinder has cavities (5) which, in addition to housing the spark and/or the fuel injectors (6) allow, in certain positions of the rotor, to expose the compression chambers (11) directly to the combustion chambers (9), to perform a process of passing of compressed gas from the intake/compression chambers to the combustion/exhaust chambers that succeed them.
2 - Internal combustion engine, according to claim n. 1, characterized by the rotor and the cylinder having one, two or more sets of chambers for intake/compression and combustion/exhaust, and for each set has the same quantity of intake/compression valves (3), combustion/exhaust valves (4), sparks (6), inlet ports (7), outlet ports (8), as well as the same quantity of openings for compressed (5) gas passage of the first to the second chambers, respectively.
3- Internal combustion engine, according to claim n. 1, characterized by the inlet and exhaust ports be located on the flat surfaces of the cylinder, on the curved surface of the cylinder, in the intake and exhaust valves, or combined with the opening and closing of these.
4 - Internal combustion engine, according to claims n. 1 and n. 3 characterized by the valves being controlled by camshafts or any other mechanism that produces the same effects .
5 - Internal combustion engine, according to claim n. 1, characterized by having one or more cylinders and respective rotors.
