Definitions
- the invention relates to the field of mechanical engineering, in particular to lever mechanisms of heat engines and can find application in various machines for driving rotating working bodies.
- a method of joint movement of pistons in a V-shaped engine in which both pistons move together along different planes along intersecting guides in opposite directions: when one piston goes up, the other piston moves down (A.F. Krainev. Mechanics of machines. Fundamental dictionary / / M.: Mechanical engineering. - 2020, p. 440, diagrams (a) and (b)) - analogue.
- the disadvantage of the known method is the movement of the pistons in intersecting directions in opposite directions, leading to a discrepancy between the thermodynamic cycle of the engine and the ideal Carnot cycle of converting thermal energy into mechanical energy of rotation of the driven cranks, which leads to low engine efficiency.
- the invention is based on the technical problem of simplifying the design of the engine, reducing its dimensions and increasing the efficiency of converting thermal energy into mechanical energy of rotation of the cranks.
- the technical result is achieved due to the fact that in the method of joint movement of pistons in a two-piston engine, the said pistons are moved along guides located in the same plane on the same vertical straight line and impart to them joint movement in the same direction for both pistons with unequal variable speeds in such a way that when moving the said pistons both in one direction and in the other, the upper piston moves at a higher speed than the lower piston to ensure an increase in the working volume between these pistons when they move together in one direction or a decrease in the working volume between these pistons when they move together in the opposite direction.
- this mechanical device for the joint movement of pistons, implementing the method specified in the invention, is made in the form of two mechanisms installed one inside the other and kinematically connected to each other, containing two three-hinged connecting rods of the same length, installed symmetrically to the vertical guide of both pistons for the kinematic connection of the lower and upper pistons with the driven cranks through cylindrical hinges made with axes of rotation parallel to each other.
- Fig. 1 shows a general view of a mechanical device that implements the proposed method of joint movement of pistons in a two-piston engine, in which, during their joint movement in one direction, one of them moves at a higher speed compared to the speed of the other piston.
- the specified mechanical device for the joint movement of the upper 1 and lower 2 pistons with rods contains a closed kinematic chain of lever links 3, 4, 5, 6, 7, 8, 9 and 10, pivotally connected to each other and to the rods of both coaxially located upper 1 and lower 2 pistons, as well as to both driven cranks 11 and 12 with rotation axes Su and SD •
- the proposed mechanical device which implements the claimed method of joint movement of pistons in a two-piston engine, operates as follows.

Abstract
L'invention concerne un procédé de déplacement combiné dans lequel les pistons se déplacent le long de guides disposés dans un même plan sur une ligne droite verticale, et auxquels on communique un mouvement conjoint dans une même direction pour les deux pistons à des vitesses alternantes et différentes de sorte que lors de leur déplacement vers l'un ou l'autre côté, le piston supérieur se déplace à une plus grande vitesse que le piston inférieur afin d'assurer une augmentation du volume de travail entre ces pistons lors de leur déplacement conjoint vers un côté (vers le haut) ou une diminution du volume de travail entre ces pistons lors de leur déplacement conjoint opposé vers l'autre côté (vers le bas). L'invention concerne un dispositif de mise en oeuvre du procédé, consistant en deux mécanismes externe et interne disposés l'un dans l'autre et reliés cinématiquement, qui comprennent au moins deux bielles à trois articulations disposées symétriquement.
