(54) PISTON MACHINE (57) Use: in mechanical engineering, as piston machines, engines, pumps and compressors. The inventive piston machine contains a housing 1, action. The latter consists of a liner 10, placed in the groove B of the piston 7, two magnetic rails 11,12 and a magnetic gear 13, fixed motionless on the output shaft 8. Magnetic rails 11, 12 are fixed on opposite sides of the groove In the liner 10 and are directed opposite and parallel to the axis the piston 7. During operation, the magnetic rails 11,12 alternately. create a magnetic circuit with magnetic gear 13 and convert the reciprocating movement

The alleged invention relates to the field of machines or engines of general volumetric displacement, in particular to reciprocating machines or engines, characterized by methods of implementation and communication between pistons and working shafts and especially with a rotating main shaft other than crankshaft, as well as joints disengaged during idling.

The aim of the invention is to simplify and improve reliability.

The list of figures in the drawings: in Fig.1 is a General view of a piston machine (section); figure 2 is a section along aa; in Fig.3 - the interaction of the elements, the movement of the piston up; figure 4 - interaction of elements, top dead center; figure 5 - the interaction of the elements, the movement of the piston down.

An example of a specific embodiment of the alleged invention is the device depicted in the drawings (Fig. 1), comprising a housing 1, a cylinder 2, the upper part of which 3 is provided with a cover 4, and the lower part 5 is provided with a cover 6. A piston 7 is placed in the cylinder 2 with a groove made thereon B, in which the output shaft 8. gears 13. The groove A of the piston 7 is made at an angle a (FIG. 1) to the axis of the piston 7.

The angle a is determined by the formula tan a = t.

where C is the horizontal stroke of the liner 10 in units of length; h is the magnitude of the stroke of the liner 10 vertically in the same length units.

. The groove 8 in the liner 10 is parallel to the axis of the piston 7. The output shaft'8 is installed in the housing 1 on bearings 14 and 15 (figure 2).

The piston machine operates as follows.

Starting position; the piston 7 in the bottom dead center (figure 1), the liner 10 in the lower position relative to the piston 7. The piston 7 moves up, moves the liner 10, the right magnetic rail 12 interacts with the magnetic gear 13 and rotates it together with the output shaft 8 (Fig.Z) counterclockwise.

Thus, the translational movement of the piston 7 is converted to the angular movement of the output shaft 8. At the top dead center (Fig. 4), at the moment of stopping the piston 7, the liner 10 moves along the groove B of the piston 7 to the upper position relative to the piston 7. The right magnetic rod 12 ceases to interact with the magnetic gear 13. The piston 7 moves down (figure 5), along with it moves the liner 10, remaining due to the inertia in the upper position relative to the piston 7. The left magnetic rack 11 interacts with the magnetic gear 13 and rotates it counterclockwise together with the output shaft 8. The translational movement of the piston 7 is converted to the angular movement of the output shaft 8. At the bottom dead center (figure 1) at the moment of stop of the piston 7, the liner 10 due to the inertia force it moves along the groove B of the piston 7 to the lower position relative to the piston 7, after which the cycle repeats. .

The alleged invention allows the reciprocating machine to convert the reciprocating movement of the piston into the angular movement of the output shaft without the use of a crankshaft and a spring or any other ratchet mechanism. In this case, friction between the transmission mechanism and the output shaft is excluded, which eliminates its wear and increases reliability.
