Description

The invention relates to a technique for converting thermal energy into mechanical energy of shaft rotation and can be used as a drive in automatic control systems, command devices, toys, etc.

The purpose of the invention is to expand the functionality of the engine through the implementation of autonomous rotation of each shaft.

FIG. 1 shows a motor, longitudinal section; FIG. 2 is an electromagnetic clutch with sliding contacts in FIG. 3 - the same cross section.

The magneto-thermal engine comprises a housing 1, mounted in the housing on axes 2 and 3, respectively, two rotors 4 and 5, one of which (A) is made of a thermomagnetic alloy losing magnetic properties when heated, and the other is of a thermomagnetic alloy acquiring magnetic properties when heated, two sources 6 and 7 of heating, a permanent magnet located offset from the heating source of the rotor and the cooling system in the form of a pallet with a viscosity of 8. The magnet is made of two parts 9 and 10, rigidly fixed on the opposite the inner surfaces of housing 1, and the axles 2 and 3 of the rotors 4 and

5 are communicated to each other by means of an additionally installed electromagnetic clutch 11, the leading part 1 2 of which is made in the form of a muffled cylindrical cup filled with a magnetic disk of 135 e. the driven part 14 is in the form of a disk mounted for rotation within the glass 12, on the outer surface of the glass 12 is placed about-. The coil 15 is connected to a source of electrical current by means of sliding contacts.

The engine works as follows.

When the winding 15 is turned off, the magnet on liquid 13 has a low viscosity and does not interfere with the independent rotation of axes 2 and 3, non-thermomagnetic rotors 4 and 5.

possessing sensitivity to a magnetic field at ambient temperature and rubbing its Curie point when it is heated, and in the zone of action of the magnet 9 there are at the same time two sections of the rotor 4 having different magnetic properties, which leads to an unbalanced torque, and

0 the rotor rotates. During rotation, the heated areas of the rotor fall into the cooling liquid, cool down and, consequently, restore their magnetic properties. At the same time, the cold areas of the rotor enter the heating zone, heat up and lose their magnetic properties. The rotor rotates continuously.

0 of the heating source 7 occurs in the opposite direction due to its discharge, for example, from an iron-hydrogen alloy, which is not sensitive to a magnetic field at an ambient temperature and acquires it when the point is heated

When winding 15 of electromagnetic clutch 11 is turned on, magnetic fluid 13 under the influence of a magnetic field significantly increases its viscosity, providing a kinematic connection of axes 2 and 3.

Independent switching on of winding 15, heating sources 6 and 7 allows realizing various programs of rotation of axes 2 and 3.
