Description

Großgasmaschinenzylinder mit Siedekühlung. Bei den neuzeitlichen Großgasmaschinenzylindern liegen bekanntlich die Einlaßventile in geräumigen Vertiefungen des Kühlmantels. In allen Fällen nun, wo mit Siedekühlung gearbeitet wird, in den Kühlmänteln also verhältnismäßig sehr hohen Temperaturen herrschen, wird das an den Wandungen der Ventilräume entlangströmende Betriebsmittel aus dem Kühlmantel Wärme aufnehmen, was eine Verminderung des Gewichts der Ladung und dadurch einen Leistungsausfall der Maschine bewirken wird. Um diesen Mißstand zu vermeiden, werden erfindungsgemäß an den Wandungen der Einlaßventilräume Schutzbleche angebracht, die das einströmende Betriebsmittel vor einer unmittelbaren Berührung mit den heißen Wänden des Kühlmantels schützen. Die dadurch herbeigeführte Wirkung kann verbessert werden, indem man zwischen dem Schutzblech und der Kühlmantelwand ein Isoliermittel einschaltet und indem man beispielsweise durch weißen Anstrich oder ähnliche Mittel dafür sorgt, daß die Wärmeausstrahlung auf das vorbeifließende Betriebsmittel möglichst gering wird.Large gas machine cylinder with evaporative cooling. With the modern large gas engine cylinders are known to be the inlet valves in spacious recesses of the cooling jacket. In all cases where evaporative cooling is used, in the cooling jackets relatively very high temperatures prevail, this is on the walls of the Operating fluids flowing along valve chambers absorb heat from the cooling jacket, resulting in a reduction in the weight of the load and thereby a loss of power the machine will cause. In order to avoid this disadvantage, according to the invention Attached to the walls of the inlet valve chambers protective plates that prevent the inflowing Equipment from direct contact with the hot walls of the cooling jacket protection. The resulting effect can be improved by adding between the mudguard and the cooling jacket wall switched on an insulating agent and by for example by painting it white or the like Funds for it ensures that the heat radiation on the equipment flowing past is as possible becomes low.

Es ist an sich schon bekannt, Isolierschichten und Schutzschirme bei Verbrennungskraftmaschinen anzuwenden. Beispielsweise hat man durch solche Einrichtungen den Baustoff des Verbrennungsraumes vor der Hitze der verbrannten Gase zu schützen gesucht oder in anderen Fällen solche Einrichtungen angebracht, um die Wärme in den verbrannten Gasen zu erhalten und zu verhindern, daß diese in unliebsamer Weise auf die Außenwand übergeht und damit in Verlust gerät. Diese Einrichtungen unterscheiden sich aber grundsätzlich von dem Gegenstand der Erfindung insofern, als es sich bei der letzteren darum handelt, tine Wärmeaufnahme der in die Maschine einströmenden frischen Betriebsmittel von den Wänden der Maschine aus zu verhindern. Wesentlich ist weiterhin der Umstand, daß diese Wände deshalb in unzulässiger Weise Wärme an das einströmende Betriebsmittel abgeben können, weil sie Räume begrenzen, die mit hocherhitztem Kühlmittel gefüllt sind, d. h. also, in denen die sogenannte Siedekühlung stattfindet. In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, Die zum Betrieb der Maschine nötige Luft strömt durch den Raum a dem Einlaßventil b zu und muß, sofern nicht besondere Vorkehrungen getroffen sind, an den Wandungen c des Kühlmantels entlangstreichen und hier Wärme aufnehmen. Um dieses letztere zu verhindern, ist ein Schutzblech d angeordnet, das in einigem Abstand von der Wand c befestigt ist und bewirkt, daß das vorbeiströmende Betriebsmittel nicht mit der heißen Kühlmantelwand c in Berührung kommt.It is already known per se to have insulating layers and protective screens Use internal combustion engines. For example, one has through such facilities to protect the building material of the combustion chamber from the heat of the burned gases sought or in other cases such facilities attached to the heat in to preserve the burnt gases and to prevent them from becoming unpleasant passes over to the outer wall and is thus lost. These bodies differ but fundamentally from the subject matter of the invention insofar as it is at the latter is about tine absorption of heat from the one flowing into the machine to prevent fresh equipment from entering the walls of the machine. Essential is also the fact that these walls are therefore exposed to heat in an inadmissible manner can release the inflowing resources because they limit spaces that with are filled with highly heated coolant, d. H. So, in which the so-called evaporative cooling takes place. In the drawing, an embodiment of the invention is shown, The air required to operate the machine flows through space a to the inlet valve b and must, unless special precautions have been taken, on the walls Stroke c along the cooling jacket and absorb heat here. To this latter To prevent this, a guard plate d is arranged, which is at some distance from the Wall c is attached and has the effect that the operating medium flowing past does not come with it the hot cooling jacket wall c comes into contact.
