Known axial piston engine comprising a housing mounted in a housing on sliding bearings with the possibility of rotation, a drive shaft with a first axis of symmetry and with a crank, a cylinder block, the axes of which are parallel to the first axis of the drive shaft, pistons with connecting rods located in the cylinders, an inclined washer with the second axis and the central pin, pivotally connected with the possibility of swinging with a crank, while the inclined washer is pivotally connected by means of connecting rods with pistons, a cross with two opposite to one third axles with pivots mounted pivotally in the housing on rolling bearings, in addition, the inclined washer is made with two additional pivots oppositely located on the fourth axis, which are pivotally mounted on the cross by means of rolling bearings, with the fourth axis being perpendicular to the third axis and intersecting at a common point with the first, second and third axes (see the description of the utility model to the patent of the Russian Federation No. 40393, IPC F 01 B 3/02, publication September 10, 2004).

The disadvantage of this engine is the cantilever arrangement of the drive shaft, which increases the dimensions of the engine, increases the load on the hinge of the central journal connected to the crank, and accordingly reduces the reliability of the engine as a whole.

The disadvantage of this engine, adopted as a prototype, is the complex trajectory of the connecting rods, which accordingly leads to a decrease in engine reliability.

The task of the invention is to increase the reliability of axial piston engines.

The essence of the invention lies in the fact that the axial piston engine comprises a cylinder block with cylinders of the working section and with cylinders of the compressor section, a crankshaft with a crank mounted in the cylinder block to rotate in the bearings, cranks, pistons of the working section and pistons of the compressor section located in cylinders in pairs with rods, inclined washers with levers connected by hinges sliding along them with rods and pistons, cylinder head of the compressor section, electric compressor from systems s electrical equipment that is turned on before starting the engine and, if necessary, to increase the degree of compression, an air receiver, a camshaft with cams for controlling through the pushers the intake and exhaust valves of the cylinder head of the working section. The fuel injectors are installed in the cylinder head. The output of the compressor section and the output of the compressor through the air receiver are connected to the inputs of the inlet valves of the cylinder head. The engine further comprises support plates, on which support rollers are supported, pivotally mounted on the levers of the inclined washers and preventing the rotation of the inclined washers together with the crank. Inclined washers are mounted in bearings with relative rotation.

The invention is illustrated by drawings, where:

figure 1 shows an axial piston engine, communities view in longitudinal section;

figure 2 is the same, a transverse section aa;

The axial piston engine contains a cylinder block 1 with cylinders 2 of the working section and with cylinders 3 of the compressor section, mounted in the cylinder block 1 with the possibility of rotation in the bearings 4, 5, the crankshaft 6 with a crank 7, located in the cylinders 2, 3 in pairs of pistons 8 the working section and pistons 9 of the compressor section with rods 10, 11, inclined washers 12, 13 with levers 14 connected by sliding hinges 15 with rods 10, 11 and pistons 8.9, cylinder head 16 of the compressor section, compressor 17 with electric drive from electro systems borudovaniya, air tank 18, a camshaft 19 with cams 20, 21 for control through the pushers 22, 23, inlet 24 and outlet 25 valves of the cylinder head 26 of the working section. In the cylinder head 26, nozzles 27 for supplying fuel are installed. The engine additionally contains support plates 28, on which support rollers 29 are supported, pivotally mounted on levers 14 of the inclined washers 12, 13 and preventing their rotation together with the crank 7. The inclined washers 12, 13 are mounted in the bearings 30 for relative rotation.

Axial piston engine operates as follows. When the crankshaft 6 is rotated in the bearings 4, 5 in the cylinders 3 of the compressor section, the pistons 9 compress the air and are forced out through the cylinder head 16 into the air receiver. 18. Intake and compression cycles. When the piston 8 is in the top dead center of cylinder 2 of the cylinder block 1, when the crankshaft 6 is rotated, the exhaust valve 25 closes and the inlet valve 24 located in the cylinder head 26 opens. When the piston 8 moves towards the bottom dead center, the working cavity of the cylinder 2 is filled with compressed air from the receiver 18. With the piston 8 in which the volume of the over-piston cavity is equal to the volume of the combustion chamber, the inlet valve 24 is closed and fuel is injected through the nozzle 27. Start of the stroke cycle. When the piston 8 reaches the bottom dead center (or with some advance), the exhaust valve 25 opens. The end of the stroke and the start of the exhaust cycle. When the piston 8 moves from the bottom dead center to the top, exhaust gas is removed.

The reciprocating pistons 8 through the rods 10, 11, the hinges 15 act on the levers 14 of the inclined washers 12, 13, which through the bearings 30 act on the crank 7, rotating the crankshaft 6 in the bearings 4, 5 and the camshaft 19 with cams 20 , 21 acting through pushers 22, 23 on the corresponding inlet 24 and outlet 25 valves of the cylinder head 26 of the engine. The support rollers 29, supported by the support plates 28, prevent the rotation of the inclined washers 12, 13 together with the crank 7 and the drive shaft 6. The compressor 17 serves to create air pressure in the air receiver 18 before starting the engine and increase the pressure during operation to increase the degree compression.

The claimed invention will improve reliability, reduce dimensions, change the compression ratio during operation of axial piston engines.
