Description

The invention relates to power engineering and can be applied in diesel generators.

The purpose of the invention is to enhance the functionality and increase reliability.

FIG. 1 shows a free piston combination machine, a general view? in fig. 2 - section A-A in FIG. 1? in fig. 3 - anchor winding with ribs, general air condition, in isometry? in fig. 4 is the same with the stem, ’in FIG. 5 is a section BB in FIG. 4 {in FIG. 6 - electric circuit of the machine. 15

The free piston combined machine contains an engine cylinder 1 with pistons 2 placed in it, a receiver 3 connected to cylinder 1, and cylinders 4 and 5 'of a multi-stage compressor connected to cylinder 1 of a multi-stage compressor with pistons 6 and 7 placed in them associated with engine pistons. The machine additionally contains two 25 linear generators 8, each of which has an anchor 9 with a winding 10, rigidly connected to the piston 6 of the compressor, and coaxially arranged first 11 and second 12 excitation windings connected by means of a rectifier 13 to the winding 10 of the armature 9, both windings 11 and 12 of excitation are located at opposite ends of the stator 14 of the generator 8. The windings 10 of the armature 9 and the like windings 11 and 12 of the excitation of the generator 8 are respectively connected to each other in series, and the pistons 2 of the engine are fitted with a synchronizing m nism 15. Multistage compressor stages 16-18 has reported conduits 19 and 20, winding 10, the armature 9 can be formed with ribs 21 and the axis 22 _<5

(Fig. 3) or with the rod 23 (Fig. 4). The cylinder 1 of the engine has purge ports 24, and the generator has a core of 2 5,

Free piston combined machine can operate in modes 5, generator, compressor and combined mode.

Start the car in. engine mode is carried out by supplying compressed air in stages 17 and 18 or using a generator 8. In generator mode, stages 17 and 18 act as a damper. Feed them from the receiver 3 through pipelines 19 and 20. The inclusion of generators 8 is due to the residual magnetization of the stator 14 and the core 25. In the process of reciprocating movement of the windings 10 they are induced EMF, variable in magnitude and direction.

The windings 11 and 12 are powered by a direct current from the rectifier 13. If one of the field windings or the armature winding is broken in any generator, the same winding in the other generator is de-energized, which ensures a symmetrical load on the machine in an emergency. When the machine is in compressor mode, the stages 16-18 perform the role of a multi-stage compressor, delivering compressed air to the consumer.

In the combined mode, the machine generates electricity and compressed air. ,

Thus, the installation of two linear generators in the machine, which have series-connected armature and excitation windings, and the supply of engine pistons with a synchronizing mechanism will allow the machine to expand its functionality and increase reliability.
