Description

DESCRIPTION

CYLINDER HEAD FOR INTERNAL COMBUSTION ENGINE WITH ROTATING VALVES

The present innovation refers to a cylinder head (or an internal combustion engine), without valves and the related to them parts, that has been invented for the first time and designed exclusively by me.

It is known that all the four stroke engines function according to the valve principle for the mixing intake and exhaust.

For example in a four cylinder engine there are at least eight (8) valves and the related to them parts for their movement.

The retrogressive movement of the pistons, the use of valves in relation to the springs rod shafts camshaft waste energy which is lost at the expense of engine power.

This energy loss in relation to the conventional way of function, causes increased fuel consumption, environmental pollution, increased engine noise, high maintenance cost, reduced engine performance etc. With the present innovation these disadvantages of the existed system are erased, as with the replacement of the old cylinder head with this of the innovation we obtain the complexity and noise reduction, power multiplication, fast engine rounds per minute (rpm) increase, enormous fuel consumption decrease, enormous reduction of fit emission to the atmosphere, the reduction of the volume and the weight of the engine, the engine lifetime prolongation, the minimal need of maintenance, the avoidance of the engine destruction in case of timing belt/chain brake and the avidity of engine rpm increase. In addition the innovation's cylinder head abolishes the intake related to them, beans shaft(s) - cylinder (s) properly mode with notches or holes which execute the valve work and comprises also the engine rpm central system. The innovation's cylinder head can be used in all existed engines using valves, independently of c.c. volume or cylinder multitude. At the specify cylinder head the valve work is implemented by one or more shaft(s) - cylinder(s) properly mode to allow the mixture intake and the exhaust gas outlet. On the contrary to the existed camshaft which has projections for the valve movement the described shaft-cylinder has notches or holes placed at the proper rotation degrees, which execute the valve work. In addition the shaft-cylinder has learning and rattans points on the cylinder head using proper metals, bearrings, rings etc., holes for the oil passage as well as exhaust gas recycling passages.

The innovation object will be easily understood with reference to the attached figures, in which is descriptively show an indicative but not restrictive innovation application example where:

FIGURE 1 Indicates the face of the cylinder head which is divided in two parts

FIGURE 2 Indicates the bottom plan of the cylinder head and the side holes for exhaust gas outlet. FIGURE 2a Indicates the upper plan of the cylinder head and the side holes for the mixture intake.

FIGURE 3 Indicates the shaft - cylinder' s face with respective degrees of a conventional camshaft. On the shaft - cylinder there are notches or holes instead of projections (cam lobes). FIGURE 4 Indicates the bottom plan of the above shaft - cylinder with the respective notches or holes for the mixture intake and the exhaust gas outlet.

FIGURE 5 Indicates the exhaust gas outlet shaft - cylinder's face, with the respective compression and exhaust gas outlet degrees.

FIGURE 6 Indicates the exhaust gas outlet shaft - cylinder's bottom plan with the respective exhaust gas outlet holes.

FIGURE 7 Indicates the mixture intake shaft cylinder's face with the indicative degrees for mixture intake timing etc.

FIGURE 8 Indicates the mixture intake shaft - cylinder bottom plan with the respective holes for the mixture intake. FIGURE 9 Indicates the internal mixture intake or internal exhaust gas outlet face and FIGURE 10 Indicates the bottom of the internal mixture intake or exhaust gas outlet with the receptive holes for mixture intake or exhaust gas outlet. Specifically, the cylinder head consists of the upper part (1) and the lower part (2) and has intake holes (3), (4), sealing part (5) made from fireproof materials, holes (6), (10) for assembly and mounting of the cylinder head on the motor, upper and lower space for the exhaust gas outlet (8) and (9), place for shaft - cylinder placement (11), combustion chamber (25), cylinder head two- parts separation points (12) and (13) which can also be undivided, multiple intake tightening bolts position (17), multiple exhaust tightness bolts passages (18), intake mixture passages (7), exhaust gas outlet passages (15), spark plugs (14), that can be placed in any other proper position in the combustion chamber, lubricant flow (16) hole(s) for lubrication of the cylinder heads moving parts (shaft - cylinder) holes for oil return to the oil chamber (28) and water flow holes (19) for the cylinder head cooling. The cylinder head of the innovation functions in combination with the internally rotating shaft, which has notches or holes (24) for the mixture intake flow and notches or holes (23) for exhaust gas outlet, shaft rotation and support (20) point of the cylinder head and holes (21) for the lubricant flow during the shaft rotation. The cylinder head has also the ability to function with two or more shafts - cylinders (figures 11, 12. 13, 14) : one shaft - cylinder or more for the mixture intake, and one or more for the exhaust gas outlet according to the familiar way of the two camshafts (figures 5-6, 7-8). In this way apart from time valve abolition also the external multiple mixture intake as well as the external multiple exhaust gas outlet are abolished.

The function of the external intake and exhaust is executed by the internal intake and exhaust respectively (fig. 9-10). The specific intake is mounted on the cylinder head at the opposite side from this that the shaft - cylinder gains its ratting power. The carburetor is screwed on the intake base (22) holes and as long as the mixture is already founded in the intake (fig.9-10) room at the proper time and as long as the intake is positioned inside the shaft - cylinder which is rotated, the three intake passages are lined -up (cylinder head, shaft- cylinder and intake passage) resulting in the mixture flow inside the combustion chamber. With the internal outlet the exact reverse function is executed. The specific cylinder, which is screwed on the engine with the shaft- cylinder properly mounted in it, as the existed shaft-cylinders are - and by taking the rotating order f. ex. From the camshaft, as the existed camshafts executes the function of the conventional engines that content valves but including the advantages mentioned above. It must be specially emphasized, at this point, the fact that the sealing part (5) can be manufactured from any proper fireproof material as fireproof rubber, springs etc.

The innovated cylinder head can be compact or it can be divided. The spark plugs, (14) can be placed at any proper place. The innovated cylinder head can be also functional in combination with two or more shaft- cylinders. The support (20), shaft rotation points, can be made of any proper and lasting material. In addition the positions of the intake (3), (4) and the outlet (8), (9) passages can have different order and shape. In conclusion any alternation or modification of the innovation at any of the points mentioned above and from anyone, it does not constitute a new innovated step and will aim to the copying and the illegitimate competition which cases have been foreseen by the law ratification's.
