The prior art STEAM ENGINE TAUER [https://geektimes.ru/post/279724/, publ. 08/31/2016], containing a spherical case, inside which a rotation and volume change disk is mounted, hemispherical elements connected to power take-off shafts are hinged on the disk on both sides, holes for supplying and discharging steam are made in the case. The disadvantages of the analogue are the difficulty in manufacturing, due to high requirements for tolerances, the complex thermal regime of the internal mechanism. Also known from the prior art ROTOR MACHINE [US 5171142 A, publ. December 15, 1992], comprising a hemispherical case with inlet and outlet openings, a disk is mounted inside the case, forming a pair of insulated volumes inside the case, half-cylindrical protrusions are made on the disk from two sides perpendicular to each other, on which rotation blades pivotally located under angle, the rotation blades are connected to the power take-off shafts.

The disadvantage of this analogue is the lack of reliability due to the high level of vibration during operation of the machine mechanisms, the difficulty of setting the angles of the position of the blades relative to the disk and power take-off shafts, and a large number of structural elements, as well as the inability to change the working volume during operation.

The closest in technical essence is the SPHERICAL MACHINE [EP 2169228 A1, publ.

A radial groove can be formed on the surface of the disk around the protrusions, which is reciprocal for a hemispherical cover.

In particular, on a disk in a spherical design, symmetrical protrusions are made on the upper and lower parts, which are separated from each other by a cylindrical groove in which a shaft with 2 symmetric sector elements with slots is located.

In particular, the protrusions on the disk have a cross section in the form of sectors with arcs of at least 30 degrees.

In particular, sector elements have a cross section in the form of sectors.

In particular, in the protrusions on the disk in a hemispherical design, when the cover operates as a rotor, through holes are made.

In particular, the holes are equipped with valves.

In particular, the ends of the shaft are a continuation of the spherical curvature of the sector elements.

In particular, the internal curvature of the arc coincides with the curvature of the lid.

The implementation of the invention

In a hemispherical embodiment, the volumetric machine consists of a disk 1 (see Fig. 1) with symmetrical protrusions 2, which are separated from each other by a cylindrical groove 5, in which the shaft 8 of the sector element 7 (see Fig. 2) with a slot 9 is located (see Fig. 3). On the surface of the disk 1 around the protrusions 2, a radial groove 6 is made, which is a response for the hemispherical cover 12. (see Fig. 5). In the arc 10, a latch 11 is installed in the form of a rod, made with the possibility of moving together with the arc in the groove of the lid for the arc 15 (see Fig. 10), in the lid 12 for the latch 11 a reciprocal vertical elongated hole is made in the form of a slot 13, while on the other hand, the latch 11 is responsive to the slot 9 of the sector element 7.

For this embodiment of a volumetric action machine, openings for supplying a working fluid or steam under pressure into the machine and exhaust can be made in protrusions 2, for example, openings 3 and 4 when using the cover as a rotor or on opposite sides of the side edges of the groove at the level of the hemispherical lids 12, for example, openings 14, wherein said openings must be equipped with valves.

The protrusions 2 have a cross section in the form of sectors with arcs of at least 30 degrees.

Element 7 has a cross section in the form of a sector.

In a spherical embodiment, the volumetric machine consists of a disk 1 (see Fig. 6) with symmetrical protrusions 2 made on the upper and lower parts, which are separated from each other by a cylindrical groove 5, in which a shaft 8 with 2 symmetrical sector elements 7 is located with slots 9 (see Fig. 7). On the surfaces of the disks 1 around the protrusions 2 are made radial grooves 6, which are mating hemispherical covers 12 (see Fig. 8). In the arcs 10, latches 11 are installed in the form of rods made with the possibility of movement together with the arc in the groove of its cover for the arc. In the covers 12 for the latches 11, counter-elongated vertical oblong holes are made in the form of a slot 13, while the latches 11 are aligned with the slots 9 of the sector elements 7.

For this embodiment of a volumetric action machine, openings for supplying a working fluid or steam under pressure into the machine and the outlet can be made on opposite sides of the side edges of the groove at the level of the opening of the hemispherical cover 12, for example, hole 14 (see Fig. 9), while openings should be equipped with valves.

In general, the operation of the machine is possible in two versions - with the fixing of the disk 1 and rotation of the cover 12 or the fixing of the cover 12 and the rotation of the disk 1, while for the spherical design of the machine it is preferable to fix the covers 12, and for the hemispherical version to fix the disk 1.

Using an example of a hemispherical embodiment, a volumetric machine is used as follows.

Let steam, for example, be supplied through one hole 3, for example, in this half of the machine volume, limited by the inner surface of the lid 12, the surface of the protrusion 2 and the lateral surface of the element 7, increased pressure is created. At the same time, in the other half of the volume of the machine, the outlet 4 is opened and thereby a reduced pressure is created in it. Thus, the element 7 begins to rotate on the shaft 8 (tilt) towards the volume with less pressure and the latch 11 begins to slide along the slot 9, which leads to the rotation of the arc 10, fixed in the groove with the cover 12, along the radial groove 6. At the time of maximum deviations of the element 7 in the chamber with high pressure open the outlet 4, block the hole 3, and in the chamber with the initial reduced pressure block the hole 4 and steam is introduced into the inlet 3. In the specified order, the following clock strokes of the machine are performed, and the cover 12 is rotated stably, from which the torque is removed and used, for example, to drive various actuators or vehicles.

During operation of the machine, it is possible to change the position of the latch 11 together with the arc 10, which leads to a change in the angle of maximum deviation of the element 7 and to a change in the maximum and minimum volumes of the machine.

Improving reliability is achieved by reducing the number of elements necessary to ensure the operation of the machine and simplifying their geometric shape. So, to ensure the operation of the claimed technical solution, only one disk 1 with protrusions 2, cylindrical 5 and radial 6 grooves, a sector element 7 with a shaft 8 and a slot 9, an arc 10 with a retainer 11, and a hemispherical cover 12 with a slot 13 are needed to work together, the length of which is greater than the diameter of the clamp rod 11.

Ensuring the possibility of changing the working volume is achieved due to the fact that the latch 11 is made with the possibility of movement together with the arc 10, and in the cover 12, a slot 13, due to which the minimum and maximum deviation angles of the sector element 7, which forms the corresponding working volumes of the machine, are changed.

The arc 10 itself (see Fig. 10) is inserted into the groove 15 of the hemisphere, while the upper part of the latch 11 is located in the slot 13 of the hemisphere and the edge 16 of the hemisphere fits snugly against the edge of the disk. The mechanism is possible in several ways - fixing the disk and rotating the hemisphere or fixing the hemisphere and rotating the disk.

Changing the position of the upper end of the latch 11 in the slot 13 will change the minimum and maximum volume of the regions in the hemisphere, divided by a hemisphere.
