Drive the displacer 3 is made in the form of a rigidly fixed on these shafts Cams 8 and 9, which interacts with a spring-loaded backing plates 18 and 19. Last through the rocker arm 20 is connected with the rod 21 of the displacer 3, with the supporting plates 18 and 19 are made in the form of grooves, the grooves which are placed in the profile surface of the Cam 8 and 9, and the arm 20 of the support plates 18 and 19 are connected with the rod 21 of the displacer 3 through the elastic element. 1 C.p. f-crystals, 3 ill. The invention relates to the field of engineering, namely the engine, engaged the engine with external heat supply. Known engine with external heat supply, containing two shafts for synchronous rotation, connected by means of gears and provided with cranks, each of which is connected through the connecting rods with your fingers traverse coaxial pistons, working and piston-displacer shifted in phase angle (Engines Sterlign. Under. Ed. M., Kruglov. M. the data with the that when the engine is at a certain point in time, the pressure under the piston becomes higher than the pressure above the piston and torque changes its sign. Gear of one of the crankshafts, which is not connected with the toothed wheel output shaft, rotates in the direction opposite to its rotation, choosing the clearance between the gears on the crankshafts. Gear associated with PTO, remains in the same position due to the inertia of the flywheel. When this happens bias traverse, causing increased friction in the nodes DITCH, thereby reducing mechanical efficiency. Also known engines have relatively low life due to uneven wear of the gears on the crankshafts, since one of them is additionally included in the gear output shaft, when this force is transmitted to the engagement, twice the force between the gears on the crankshafts. Also known engine with external heat supply, containing the actuator piston and the displacer drive, comprising two shaft mounted gears associated with the intermediate gear, and drive the displacer is made in the form rigidly attached to the m beam associated with the displacer rod. (The device on the bus.St. USSR N 1016552, taken as a prototype). The disadvantage of this device is the design complexity of Cams of the drive mechanism of crowding, lack of reliability supporting plates and rocker, the presence of a rigid contact between the displacer rod and the rocker does not provide uniform distribution of the load on the Cams, which causes increased wear of friction pairs, the misalignment of the rod, and also increases the noise level. The aim of the invention is to simplify the design of Cams, increased durability, improved reliability and improved performance of the engine. This goal is achieved by the fact that the engine with external heat supply, containing the actuator piston and the displacer drive, comprising two shaft mounted gears associated with the intermediate gear wheel and drive the displacer is made in the form of a rigidly fixed on these shafts Cams interacting with spring-loaded to them backing plates, through which the rocker arm associated with the displacer rod, a base plate made in the form of grooves, the grooves which are placed in the profile surface of the Cam, and the rocker opennig between the displacer rod and rocker two stepped bushing of elastic material with the ability to change the stiffness by compressing them screw pair. The rocker is connected to the base plate by welding or, even easier, can be made integral with the base plate in the form of stamped Z-shaped sheet material. The analysis of the prior art technical solutions showed that a significant distinguishing features of the proposed device in other technical solutions are not found, which allows to make a conclusion on the conformity of the proposed technical solution the criterion for significant differences. In Fig. 1 shows a kinematic diagram of the proposed engine; Fig.2 node I in Fig.1; Fig.3 section a-a in Fig.1. The engine consists of a cylinder I, which houses the piston 2 and the displacer 3. The drive contains the shafts 4 and 5, on which is rigidly fixed gears 6 and 7 and the Cams 8 and 9. The shafts 4 and snabjeny cranks 10 and 11, each of which is connected through the connecting rods 12 and 13 with the head plate 14 and the rod 15 of the piston 2. Gears 6 and 7 are in engagement with the intermediate gear wheel 16, is made with two toothed crowns, inner and outer, and the inner crown is associated with the gear 6, and the external gear 7. A gear wheel 16 mounted on the shaft 17. With Cams 8 and 9 vsims 3 through the elastic element 22, designed as two stepped bushing of elastic material, which through the washer 23 is fixed by nuts 24. The supporting plates 18 and 19 are made in the form of grooves, the grooves of which are biased to the core surfaces of Cams 8 and 9 by means of a spring 25 mounted between the thrust bracket 26 and the rocker 20, also having a grooved shape. The shafts 4,5 and 17 placed in the bearings 27. The engine works as follows. With the expansion of the heated gas piston 2 and the displacer 3 moves down, and the work makes only the piston 2, as the gas pressure on both sides of the displacer is approximately the same. The reciprocating movement of the piston 2 is converted through the yoke 14, the connecting rods 12 and 13, the cranks 10 and 11 in the rotational movement of the shafts 4 and 5, which through gears 6 and 7 and the intermediate gear 16 transmits the rotation of the shaft 17. During the compression stroke gas piston 2 will move upwards, and the corresponding movement will make United with him the above links. The required optimal law of change of volume of the hot cavity of the cylinder is provided by the Cam mechanism, since the displacer 3 via the shaft 21 is connected with necessary law of motion of the displacer 3. Accommodation profile surfaces of Cams 8 and 9 in the grooves grooves supporting plates 18 and 19 eliminates the possibility of slipping and breaking the orientation of the supporting plates on Cams and compared with the prototype greatly simplifies the manufacturing technology of Cams, eliminating the need for restrictive shoulder. In addition, the grooved shape of the supporting plates 18 and 19 and the rocker arm 20 increases the rigidity of this support block, which is important because the point of application of the loads are located at significant distances and operate in different vertical planes. The connection of the rocker arm 20 supporting plates 18 and 19 with the rod 21 by means of the elastic element 22 allows the plates to samoustraniajutsia in any plane on Cams 8 and 9, providing a permanent contact grooves grooves with the profile Cam surfaces, and a uniform minimum wear of Cams and grooves of the support plates. In addition, the absence of direct hard contact between the displacer rod and the rocker arm supporting plates significantly reduces noise and eliminates the bias rod displacer, simplifies the adjustment, maintenance and repairs. These advantages simplify design is in General. 1. Engine with external heat supply, containing the actuator piston and displacer comprising two shaft mounted gears associated with the intermediate gear, and drive the displacer is made in the form of a rigidly fixed on these shafts Cams interacting with spring-loaded to them backing plates, through which the rocker arm is connected with the rod displacer, wherein the base plate is made in the form of grooves, the grooves which are placed in the profile surface of the Cam, and the Cam supporting plates connected with the rod displacer means of an elastic element. 2. The engine under item 1, characterized in that the elastic element is designed as placed between the displacer rod and rocker two stepped bushing of elastic material.
