Wesen der Erfindung Die angeführten Mängel beseitigt in beträchtlichem Maß die Dichtungs- und Kühlungsart der Kolbenmechanismen, vor allem der Verbrennungsmotoren mit einer geradlinigen Bewegung des Kolbens, der Verbrennungsmotoren mit der Rotationsbewegung der Kolben und der Verbrennungsmotoren mit der Kreiselbewegung des Kolbens nach der Erfindung. Die Flüssigkeit, die durch ein Öffnungssystem in die Umfassungslücke fließt, füllt den Raum der Umfassungslücke, dichtet den Raum zwischen der Umfassungswand des Kolbens und des Gehäuses, wodurch sie den Gasübergang von dem Raum auf einer Kolbenseite in den Raum auf anderer Kolbenseite verhindert. Diese Flüssigkeit nimmt die Wärme von der Gehäusewand und der Umfassungswand des Kolbens ab, dann fließt sie in den Raum auf einer Kolbenseite und in den Raum auf anderer Kolbenseite. Durch die eintretende Flüssigkeitsmenge wird sowohl der Dichtungsgrad des Arbeitsraums als auch die Menge der abgenommenen Wärme reguliert, also die Temperaturabsenkung des Kolbens und der Gehäusewand des Kolbenmechanismus.Essence of the invention The deficiencies cited largely eliminate the sealing and cooling manner of the piston mechanisms, especially the internal combustion engines with a linear movement of the piston, the internal combustion engines with the rotary movement of the pistons and the internal combustion engines with the gyroscopic movement of the piston according to the invention. The liquid that flows through an opening system into the peripheral gap fills the peripheral gap space, seals the space between the peripheral wall of the piston and the housing, thereby preventing gas transfer from the space on one side of the piston to the space on the other side of the piston. This liquid absorbs the heat from the housing wall and the peripheral wall of the piston, then flows into the space on one side of the piston and into the space on the other side of the piston. The amount of liquid entering regulates both the degree of sealing of the working space and the amount of heat removed, that is, the temperature drop in the piston and the housing wall of the piston mechanism.
In dem Kolben des Kolbenmechanismus befindet sich das zum Flüssigkeitsverteilung dienende Öffnungssystem, dieses Öffnungssystem hat mindestens eine Längsöffnung, die mit mindestens einer Queröffnung verbunden ist, jede Queröfnung mündet in der Umfassungswand des Kolbens ein. Zwischen der Umfassungswand des Kolbens und dem Gehäuse gibt es die Umfassungslücke, die durch die Konstruktionskolbenlagerung gegenüber dem Gehäuse so gebildet ist, dass sich der Kolben nicht berührt oder sich nur an der Stellen der zur Abgrenzung der Breite der Umfassungslücke dienenden Vorsprünge berührt.In the piston of the piston mechanism is the opening system used for the distribution of liquid, this opening system has at least one longitudinal opening which is connected to at least one transverse opening, each transverse opening opens into the peripheral wall of the piston. Between the circumferential wall of the piston and the housing there is the circumferential gap, which is formed by the structural piston bearing relative to the housing in such a way that the piston does not touch or only touches at the points of the projections used to delimit the width of the circumferential gap.
Es ist vorteilhaft, wenn die Queröffnung mit der Verteilungsnut verbunden ist, die sich an der Umfassungswand des Kolbens befindet. An der Umfassungswand des Kolbens kann auch eine oder mehrere Dichtungsnuten sein. Es können auch mehrere Verteilungsnuten sein.It is advantageous if the transverse opening is connected to the distribution groove, which is located on the peripheral wall of the piston. One or more sealing grooves can also be on the peripheral wall of the piston. There can also be several distribution grooves.
Die Längsrichtung ist in den Verbrennungsmotoren mit einer geradlinigen Bewegung des Kolbens in der Kolbenstange mit Vorteil hergestellt. Die Verbrennungsmotoren mit der Rotationsbewegung der Kolben haben in dem Ring jedes Kolbens eine Umfassungsverteilungsnut, die mit den Längsöffnungen verbunden ist. Jede Längsöffnung ist mit der Queröffnung verbunden. Es ist vorteilhaft, wenn in jedem Kolbensegment die Queröffnung mit einer oder mehreren Verteilungsnuten verbunden ist. Vorteilhaft ist auch die Lösung, wenn es an der Umfassungswand des Kolbensegments eine oder mehrere Dichtungsnuten gibt.The longitudinal direction is advantageously produced in the internal combustion engines with a linear movement of the piston in the piston rod. The internal combustion engines with the rotary motion of the pistons have a circumferential distribution groove in the ring of each piston, which is connected to the longitudinal openings. Each longitudinal opening is connected to the transverse opening. It is advantageous if the transverse opening is connected to one or more distribution grooves in each piston segment. The solution is also advantageous if there is one or more sealing grooves on the peripheral wall of the piston segment.
Die Verbrennungsmotoren mit der Kreiselbewegung des Kolbens haben zwischen dem Gehäuse und den Seitenwänden die Seitenlücken. Die Umfassungsverteilungsnut ist durch die Längsöffnungen mindestens mit drei Queröffnungen verbunden. Jede Queröffnung ist mit der Verteilungsnut an der Spitze des Kolbens und mit zwei Paaren der sich an den Seitenwänden befindenden Seitenverteilungsnuten verbunden.The internal combustion engines with the rotary motion of the piston have the side gaps between the housing and the side walls. The circumferential distribution groove is connected to at least three transverse openings by the longitudinal openings. Each transverse opening is connected to the distribution groove at the top of the piston and to two pairs of the side distribution grooves located on the side walls.
Die Lösung nach der Erfindung hat vor allem diese Vorteile: zwischen dem Kolben und dem Gehäuse des Kolbenmechanismus befindet sich eine mit der Flüssigkeit gefüllte Lücke, wodurch die Reibung reduziert wird und zur Schmierung der Fläche zwischen dem Kolben und dem Gehäuse kein Öl erforderlich ist. Die Gehäusewand des Kolbenmechanismus wird von der Innenseite gekühlt werden und deswegen ist es nicht notwendig, die Gehäusewand von der Außenseite durch den Wärmeübergang durch die Gehäusewand zu kühlen, wodurch der Wärmewirkungsgrad hauptsächlich der Verbrennungsmotoren erhöht wird. Die Flüssigkeit dient gleichzeitig zur Dichtung und Kühlung.The solution according to the invention has these advantages in particular: there is a gap filled with the liquid between the piston and the housing of the piston mechanism, as a result of which the friction is reduced and no oil is required to lubricate the surface between the piston and the housing. The housing wall of the piston mechanism will be cooled from the inside and therefore it is not necessary to cool the housing wall from the outside through the heat transfer through the housing wall, whereby the thermal efficiency of mainly the internal combustion engines is increased. The liquid is used for sealing and cooling at the same time.
Die Flüssigkeit wird nach der Aufwärmung von dem Arbeitsraum des Kolbenmechanismus abgeleitet, wodurch die Wärme von dem Innenraum des Kolbenmechanismus abgeführt wird. Die Lösung nach der Erfindung ist vor allem für Dichtung und Kühlung der Verbrennungsmotoren vorteilhaft. Die Vorteile der Lösung nach der Erfindung zeigen sich hauptsächlich dann, wenn diese Lösung bei der Verbrennungsmotoren mit der Rotationsbewegung des Kolbens und der Verbrennungsmotoren mit der Kreiselbewegung des Kolbens benutzt wird. Übersicht der Abbildungen an der ZeichnungenAfter heating, the liquid is discharged from the working space of the piston mechanism, whereby the heat is dissipated from the interior of the piston mechanism. The solution according to the invention is particularly advantageous for sealing and cooling the internal combustion engines. The advantages of the solution according to the invention are mainly evident when this solution is used in internal combustion engines with the rotary movement of the piston and in internal combustion engines with the rotary movement of the piston.
