Abstract

The subject of the invention is a pendulum engine for multipurpose usage. The pendulum engine is characterised in that it comprises an engine block (3) (body) with a head, a shaft (1) with at least one blade (2), combustion chambers (4) (5). The shape of the combustion chambers (4) and (5) is determined by the shape of the blade (2), and the depth of the chamber determines the range of the angular movement (2α) which is made by the blade (2) during work. The blade (2) which is fixed to the pendulum engine shaft (1) on its both sides plays the role which is adequate to a piston role in a piston combustion engine. According to the invention a pendulum engine has a positive influence on reducing a size of combustion engines even up to several dozen percent simultaneously keeping the same engine cubic capacity. The pendulum engine has the same advantages as engines with classical piston-crank systems and engines using a rotary motion. At its high efficiency which is comparable to the efficiency of engines with classical piston-crank systems its construction is characterised in a significantly lower consumption of raw materials and additionally it is believed that a simplicity of such construction causes fewer emergency situations.

Description

Pendulum engine

The subject of the invention is a pendulum engine for multipurpose usage.

Presently known combustion engines in most cases are built as piston engines or rotational engines and have many faults such as troubles with a seal having a significant weight in relation to the power output and what is presently very important, they are not much efficient, consume too much fuel in relation to power output and they are characterised in a material consumption design.

Development of combustion engines tends towards a creation of an engine which would have the possibly lowest weight and maintain an engine cubic capacity to strive for the greatest possible efficiency.

The essence of the invention is that the pendulum engine with a combustion chamber in which the energy of combustion is being converted into a swinging motion of a blade fixed to a shaft, playing role which is adequate to a piston role in a piston combustion engine, and the engine principle of operation is to use the same combustion chamber space by both sides of the blade placed inside the combustion chamber on the engine shaft.

The pendulum engine has an engine block (body) with a head, having a valve-ignition system and a shaft having at least one blade. There are combustion chambers on the both sides of the blade inside the engine block. The shape of the combustion chamber depends on the shape of the blade and its depth determines the range of the angular movement which is made by the blade during work. According to the invention there must be at least one blade inside the engine and it is advantageous to use up to four blades.

The engine works in such way that there is air-fuel mixture supplied to one chamber (suction) and at the same time the second chamber makes an exhaust, and the blade separating the chambers is being moved increasing the space of the first chamber and at the same time decreasing the space of the second chamber, when the first chamber makes compression at the same time the second chamber makes suction and the blade is being moved increasing the space of the second chamber and decreasing the space of the first chamber, the fuel ignition in the first chamber takes place and the chamber performs the working cycle, and at the same time the second chamber makes compression thanks to which the blade is being moved increasing the space of the first chamber and at the same time decreasing the space of the second chamber, when the first chamber makes the exhaust at the same time the second chamber performs the work and the blade is being moved increasing the space of the second chamber and simultaneously decreasing the space of the first chamber.

Working cycles of the pendulum engine are synchronized in such way that when there is a suction cycle on one side of the blade, or the work, there must be compression or the exhaust on the other side of the blade. The swinging motion made by the engine blade is transmitted by the engine shaft.

The subject of the invention is shown in the attached figures where fig.l shows the pendulum engine in a front view with the engine blade shown too, fig.2 shows the pendulum engine in an axonometric view, fig.3 shows one blade pendulum engine in the front view, fig.4 shows two blade pendulum engine in the front view, fig.5 shows three blade pendulum engine in the front view, fig.6 shows four blade pendulum engine in the front view.

The pendulum engine with combustion chambers 4 and 5 in which the combustion energy is being converted into a swinging motion of the blade 2 fixed to the shaft 1 playing role which is adequate to a piston role in the piston combustion engine, and the engine principle of operation is to use the same combustion chamber space by both sides of the blade 2 placed inside the combustion chambers 4 and 5 on the engine shaft 1.

The pendulum engine has the engine block 3_ (body) with head having a valve-ignition system and the shaft 1 having at least one blade 2. There are combustion chambers 4 and 5 on the both sides of the blade 2 inside the engine block 3. The shape of the combustion chambers 4 and 5 depends on the shape of the blade 2, and the depth of the chamber determines the range of the angular movement 2α which is made by the blade 2 during work. There must be at least one blade 2 inside the engine and it is advantageous to use up to four blades 4.

The engine works in such way that there is air-fuel mixture supplied to one combustion chamber 4 (suction) and at the same time the second combustion chamber 5 makes an exhaust, and the blade 2 separating the chambers 4, and 5 is being moved increasing the space of the first combustion chamber 4, and at the same time decreasing the space of the second combustion chamber 5, when the first combustion chamber 4 makes compression at the same time the second combustion chamber 5 makes suction, and the blade 2 is being moved increasing the space of the second chamber 5, and simultaneously decreasing the space of the first combustion chamber 4, the fuel ignition in the first combustion chamber 4 takes place and the combustion chamber 4 performs the working cycle, and at the same time the second combustion chamber 5 makes compression thanks to which the blade 2 is being moved increasing the space of the first combustion chamber 4, and simultaneously decreasing the space of the second combustion chamber 5, when the first combustion chamber 4 makes the exhaust at the same time the second combustion chamber 5 performs the work and the blade 2 is being moved increasing the space of the second combustion chamber 5, and simultaneously decreasing the space of the first combustion chamber 4.

Working cycles of the pendulum engine are synchronized in such way that when there is a suction cycle on one side of the blade 2, or the work, there is compression or the exhaust on the other side.

The swinging motion being performed by the engine blade 2 is being transmitted by the engine shaft 1.
