Die von dem Verdichtungsgrad abhängige Temperatursteigerung kann deshalb auch bei Verdichtung auf hohen Druck derart abgepasst werden, dass die Temperatur niemals bis auf eine für die empfindlichen Teile des Hochdruckzylinders, wie   Kolbenpackung,   Ventilfedern,   schädliche   Höhe steigt. Dies ist für die Betriebssicherheit des Kompressors von grosser Bedeutung. Um eine vollständige Dichtung zwischen dem Kolben 11 und dem Zylinder 2 zu bewirken, können nämlich Dichtungsringe aus Metall nicht verwendet werden, sondern der Kolben muss mit Manschetten aus Leder. Vulkanfiber oder dgl. versehen werden, die von dem Druck im Zylinder gegen die Zylinderwandung gepresst werden.

   Bei Verdichtung auf sehr hohe   Drücke   könnte die Temperatur im Zylinder 2 bis auf eine solche Höhe steigen, dass die Packung verbrannt werden würde, falls der Hochdruckzylinder nicht mit Luft gleichen Druckes von dem Luftbehälter 3 gespeist und der Verdichtungsgrad im Zylinder 2 dadurch innerhalb berechneter Grenzen erhalten werden würde. Durch die Vereinigung beider Arten von Zylindern wird somit eine betriebssichere Kompressoranlage geschaffen.

The temperature increase, which is dependent on the degree of compression, can therefore also be adjusted in the case of compression to high pressure in such a way that the temperature never rises to a level that is detrimental to the sensitive parts of the high pressure cylinder, such as piston packing, valve springs. This is of great importance for the operational safety of the compressor. In order to achieve a complete seal between the piston 11 and the cylinder 2, sealing rings made of metal cannot be used, but the piston must be fitted with sleeves made of leather. Vulcanized fiber or the like are provided, which are pressed against the cylinder wall by the pressure in the cylinder.

   With compression to very high pressures, the temperature in cylinder 2 could rise to such a level that the packing would be burned if the high-pressure cylinder was not fed with air of the same pressure from the air tank 3 and the degree of compression in cylinder 2 was thereby maintained within calculated limits would be. By combining both types of cylinders, an operationally reliable compressor system is created.

Claims

Of course, several low-pressure cylinders of the type described can also be combined with several high-pressure cylinders in the manner indicated above. Single-cylinder pumps in which a cylinder is arranged like the cylinder 1 described above are already known, which is why a contactor is only claimed for the combination specified in the following claim.

PATENT. CLAIM : Compressor for compressing air or similar gases in several stages, characterized by the combination of one or more low-pressure cylinders, which are equipped with one or more common suction valves and in the wall with one or more, EMI2.1 Gas are provided, with one or more high-pressure cylinders of conventional design and a cooled air container in between, for the purpose of keeping the pressure in the air container as constant as possible even if the suction valves of the low-pressure cylinders are not or fully opened and the temperature increase during compression in the high-pressure cylinder is kept within such limits that the piston packing is made of leather,

Vulcanized fiber and the valves of the cylinder etc. are not damaged.
