Abstract

The invention relates to mechanical engineering and makes it possible to increase the efficiency of the device by reducing volumetric losses and to provide the possibility of quantitative regulation. The working fluid (PT) under pressure enters the cylinder blocks (BC) 4 and, expanding, acts on roller pistons (RP) 5. Each RP 5 is made of two parts connected by a sleeve placed in channel 6. The latter is made of a material with a higher linear expansion coefficient than RP 5. The latter transmits the force on the runner rollers 7, as a result of the interaction of which with the profiled surface 2 there are forces that turn the movable element 3 in a clockwise direction. When the outlet openings of the BC 4 are combined with the outlet openings of the exhaust spool 13, the RT exhaust occurs. The engine is regulated by changing the amount of PT supplied to BC 4 when the inlet ports of the inlet slide are displaced relative to the cylindrical sections: 10. The number of the latter is equal to the number of inlets. 1 hp ff, 4 ill. A-A with (L from 13 to CX) 00 00 Fig2

The invention relates to mechanical engineering, in particular to heat piston machines, using heat gas, steam and the like as a working medium.

The purpose of the invention is to increase the efficiency of the device by reducing volumetric losses, as well as to enable quantitative control.

Figure 1 shows the engine, a longitudinal section; figure 2 - section aa in Fig, 1; on fig.Z - cylinder block; Fig. 4 shows the loading circuit of a roller piston and a runner roller.

The vehicle engine contains a stationary element 1 with a profiled multiple cam surface 2, a movable element 3 provided with blocks of 4 cylinders with self-sealing floating roller pistons 5 with an internal channel 6, and a spool distribution mechanism. Each cylinder block 4 is additionally provided with a bendung roller 7 located between the roller piston 5 and the profiled surface 2 of the fixed element 1, and the roller piston 5 is made of two parts 8 connected together by a sleeve 9 made in the inner channel 6 of the piston 5 with

with a higher linear-to-35 stroke. The rings 15 limit the expanded than the material of the piston 5. The maximum deformation of the piston 5.

The sections 10 of the profiled cam surface 2,: minimum, remote from the axis of rotation of the movable element 3, are cylindrical, and their number is equal to the number of inlet openings 11 of the spool mechanism.

The latter consists of an inlet spool 2 with inlet ports 11 and an outlet spool 13 with outlet ports 14.

Inside the channel 6 of the roller piston, engine control is a change in the number of working body supplied to the 4 cylinder blocks, when the inlet holes 11 of the spool 12 are displaced, relate

n 5 there are, apart from the sleeve 9, bounded by 50 cylindrical sections 10 supporting rings 15 and filling pipes 16. Each cylinder block is equipped with thermally insulating oil-removable liners 17,

the impact of the drive 18. Invention formula The inlet spool 12 is kinematically connected to the actuator 18, and the exhaust spool 13 is in frictional engagement with the movable element 3 five 0 five 0 and has two working positions: Forward and Backward. In each block of 4 units there are inlet 19 and outlet openings. The device works as follows. The working fluid (gas, steam) under pressure enters through the inlet spool 12 and inlet openings 11 and 19 in the cylinder blocks 4 and expands, acts on the pistons 5, which transmit force to the runner rollers 7, as a result of their interaction with the profiled surface 2 there are forces that turn the movable element 3 (in figure 4 - clockwise). When achieving the alignment of the exhaust ports of the block. 4 cylinders with outlets 14 of the outlet spool 13 exhaust the working body. The seal along the forming roller piston 5 (Fig. 4) is achieved by the fact that under pressure of the working fluid on one side and the force from the runner roller 7 on the other, the thin-walled piston 5 is deformed from the original round shape into the oval shape, as a result The piston 5, installed when the cylinder block 4 is assembled, decreases and then goes into tension, the compaction of the piston 5 preserving to the end along the ends is accomplished by pressing the parts 8 of the piston 5 towards them by pressure in the gap (Fig. 3). In addition, when working with high-temperature working fluid, biasing force occurs due to thermal expansion of the sleeve 9. The regulation of the engine is carried out by changing the amount of working fluid supplied to the 4 cylinder blocks when the inlet apertures 11 of the spool 12 are displaced relative to the cylindrical sections 10 under but 10 cylindrical sections under the impact of the drive 18.
