Abstract

The invention relates to the field of propulsion engineering, namely to internal combustion engines.The internal combustion engine piston comprises a compression ring placed in a groove, made in the piston head, consisting of two outer rings (1, 2) with joints and a third inner ring (3) with joint, the thickness of which is equal to the thickness of the two outer rings (1, 2). Additionally in the piston head, at the level of the groove, perpendicular to the axis of the piston are made through channels (4, 5), intersecting at an angle of 45° or 90° and communicating with the channels (6, 7), made parallel to the axis of the piston, symmetrically, which communicate with the combustion chamber.The technical result consists in the permanent sealing of the combustion chamber for the entire service life of the outer compression rings.

Description

Invenţia se referă la domeniul construcţiei de motoare, şi anume la motoarele cu ardere internă. The invention relates to the field of engine construction, namely to internal combustion engines.

Se cunoaşte un piston, în canalul căruia sunt instalate două segmente exterioare şi un al treilea segment interior, grosimea căruia este egală cu grosimea celor două segmente sau lăţimea canalului pistonului. Pe suprafaţa interioară a segmentelor exterioare sunt executate renuri, în care este fixat un capăt al încheieturii segmentului interior, celălalt capăt fiind încovoiat în interior şi introdus în gaura executată pe piston [1]. A piston is known, in the channel of which two outer segments and a third inner segment are installed, the thickness of which is equal to the thickness of the two segments or the width of the piston channel. Reins are made on the inner surface of the outer segments, in which one end of the joint of the inner segment is fixed, the other end being bent inside and inserted into the hole made on the piston [1].

Dezavantajul invenţiei constă în aceea că la introducerea segmentelor în canalul pistonului curbura interioară a îmbinării segmentului interior va necesita desfacerea mai largă a segmentului, ceea ce va conduce la deformarea diametrului iniţial al segmentului interior, în cazul în care acesta este executat din oţel, sau la ruperea acestuia, în cazul în care acesta este executat din fontă. The disadvantage of the invention is that when inserting the segments into the piston channel, the inner curvature of the inner segment joint will require the segment to be opened wider, which will lead to the deformation of the initial diameter of the inner segment, if it is made of steel, or to breaking it, if it is made of cast iron.

De asemenea, presiunea amestecului la comprimare sau a gazelor la dilatare acţionează pe suprafaţa superioară a segmentului exterior şi îmbinările segmentelor exterioare, strângând rigid segmentul interior împrejurul diametrului interior al canalului pistonului, ca rezultat, se încalcă ermetizarea constantă a camerei de ardere. Also, the pressure of the mixture during compression or the gases during expansion acts on the upper surface of the outer segment and the joints of the outer segments, rigidly tightening the inner segment around the inner diameter of the piston channel, as a result, the constant sealing of the combustion chamber is violated.

Problema pe care o rezolvă prezenta invenţie constă în direcţionarea presiunii din camera de ardere spre suprafaţa interioară a segmentului interior, care prin acţionarea asupra segmentelor exterioare va contribui la evitarea jocului dintre piston şi cilindru pentru toată perioada de exploatare a segmentului de compresiune. The problem that the present invention solves consists in directing the pressure from the combustion chamber to the inner surface of the inner segment, which by acting on the outer segments will contribute to avoiding the play between the piston and the cylinder for the entire period of operation of the compression segment.

Pistonul motorului cu ardere internă, conform invenţiei, înlătură dezavantajele menţionate mai sus prin aceea că conţine un segment de compresiune amplasat într-o canelură, executată în capul pistonului. Segmentul de compresiune este compus din două segmente exterioare cu îmbinări şi un al treilea segment interior cu îmbinare, grosimea căruia este egală cu grosimea celor două segmente exterioare. Suplimentar în capul pistonului, la nivelul canelurii, perpendicular axei pistonului sunt executate canale străpunse, care se intersectează sub un unghi de 45° sau 90° şi comunică cu nişte canale, executate paralel axei pistonului, simetric, care comunică cu camera de ardere. The piston of the internal combustion engine, according to the invention, removes the disadvantages mentioned above in that it contains a compression segment located in a groove, executed in the piston head. The compression segment is composed of two outer segments with joints and a third inner segment with joints, the thickness of which is equal to the thickness of the two outer segments. Additionally, in the piston head, at the level of the groove, perpendicular to the piston axis, pierced channels are executed, which intersect at an angle of 45° or 90° and communicate with some channels, executed parallel to the piston axis, symmetrically, which communicate with the combustion chamber.

Rezultatul tehnic constă în ermetizarea constantă a camerei de ardere pentru întreg termenul de exploatare a segmentelor exterioare de compresiune. The technical result consists in the constant sealing of the combustion chamber for the entire term of operation of the external compression segments.

Invenţia se explică prin desenele din fig. 1, 2, care reprezintă: The invention is explained by the drawings in fig. 1, 2, which represent:

- fig. 1, vederea de ansamblu a cilindrului şi pistonului motorului cu ardere internă, în secţiune; - fig. 1, general view of the cylinder and piston of the internal combustion engine, in section;

- fig. 2, vederea de sus a pistonului motorului cu ardere internă. - fig. 2, top view of internal combustion engine piston.

Pistonul motorului cu ardere internă conţine un segment de compresiune amplasat într-o canelură, executată în capul pistonului. Segmentul de compresiune este compus din două segmente exterioare 1 şi 2 cu îmbinări şi un al treilea segment interior 3 cu îmbinare. Grosimea segmentului interior 3 este egală cu grosimea celor două segmente exterioare 1 şi 2. În capul pistonului, la nivelul canelurii, perpendicular axei pistonului sunt executate canale străpunse 4 şi 5, care se intersectează sub un unghi de 45° sau 90° şi comunică cu canalele 6 şi 7, executate paralel axei pistonului. Canalele 6 şi 7 comunică cu camera de ardere. The piston of the internal combustion engine contains a compression segment located in a groove, executed in the piston head. The compression segment is composed of two outer segments 1 and 2 with joints and a third inner segment 3 with joints. The thickness of the inner segment 3 is equal to the thickness of the two outer segments 1 and 2. In the piston head, at the level of the groove, perpendicular to the piston axis, pierced channels 4 and 5 are made, which intersect at an angle of 45° or 90° and communicate with channels 6 and 7, executed parallel to the axis of the piston. Channels 6 and 7 communicate with the combustion chamber.

Pistonul motorului cu ardere internă funcţionează în modul următor. The internal combustion engine piston works in the following way.

Presiunea din camera de ardere acţionează prin canalele 6 şi 7, care comunică cu canalele străpunse 4 şi 5, asupra suprafeţei interioare a segmentului interior 3, care prin dilatare acţionează asupra segmentelor exterioare 1 şi 2, ceea ce va asigura o contactare strânsă a segmentelor exterioare 1 şi 2 cu pereţii cilindrului, în timp ce pistonul efectuează cursa de comprimare a amestecului de ardere şi evacuare a gazelor de eşapament, când în cilindru există presiune înaltă. The pressure in the combustion chamber acts through the channels 6 and 7, which communicate with the pierced channels 4 and 5, on the inner surface of the inner segment 3, which by expansion acts on the outer segments 1 and 2, which will ensure a close contact of the outer segments 1 and 2 with the cylinder walls, while the piston carries out the stroke of compression of the combustion mixture and exhaust gases, when there is high pressure in the cylinder.
