The invention relates to an energy converter system wherein the energy is converted according to the principle of positive volume displacement, where the rate of energy conversion is always defined by the applied valves and the energy conversion principle in such a way that its piston having shape of triangle with arched sides and rounded vertices performs alternately rotating and planetary movements in its radius points, the shape of the housing of the piston is determined by the dimensions of the piston movement and the rotating and planetary movement of the piston is provided by couplings of stepped cogwheels.

The state of art is defined prevailingly by reciprocating engines with linear piston movement. There are known bladed rotating energy converter machines. Up to now only the Wankel engine is known as energy converter with piston performing rotating and planetary movement. The most important drawback of these inventions is the too high energy loss including a great part of mechanical loss in relation to the input energy. The aim of the invention is to create a construction more applicable than the existing ones mainly in relation to its operation. The mechanical losses of the energy converter can be reduced in this way.

According to this aim the invention relates to an energy converter machine wherein the energy conversion is performed using the principle of positive volume displacement and the relation of energy conversion is always determined by the applied valves and the energy conversion principle in such a way that the piston having shape of a triangle with arched sides and rounded vertices performs alternately rotating and planetary movement in its radius points, the shape of the housing of the piston is determined by the dimensions of the piston movement and the rotating and planetary movement of the piston is provided by couplings of stepped cogwheels.

The principle underlying the operation of the energy converter system is that the continuous rotating and planetary movement of the piston is provided with couplings of stepped cogwheels. The process of operation is shown in the Figure 7.

The initial position is defined as the meeting of points " c" and " /" , as well as

the meeting of the points "b" and "II". The expansion extends until the meeting of points "a" and "I" using "b" and "II" as center of rotation.

The next movement extends until the meeting of points "c" and "II" using "a" and "F as center of rotation.

The invention, as a construction operating on the base of the principle of positive volume displacement has the main advantage in relation to all the energy converting machines that the degree of energy conversion is proportional, while that value is always zero in the traditional known alternating piston engines at the initial position of the piston. This fact is shown in the Figure 8 where a movement equal to actual displacement is marked on the axis of abscissa and the torque values deriving from the unit value of input energy are marked on the axis of ordinate in the diagram. "Torque 1" corresponds to the torque values of a traditional alternating piston engine, while "Torque 2" corresponds to the torque values of the system according to the invention. Consequently, the quantity of the converted energy is constant while the input energy is constant in the machine according to the invention.

The most important losses of the known energy converters operating on the principle of positive volume displacement arise from the fact that the momentary energy transfer has the most disadvantageous value at the highest pressure belonging to the least volume. Consequently, the internal energy is transformed to the energy of torque suffering the highest static loss. The static status becomes more advantageous while the volume increases but the pressure being present diminishes to a small part of its initial value.
