Description

Einstufiger Brennkraft-Gegenlauf-Freiflugkolbenverdichter Die Erfindung betrifft einen einstufigen Brennkraft-Gegenlauf-Freiflugkolbenverdichter, bei dem der Ausgleich zwischen der beim Verdichtungshub und der beim Rückhub geleisteten Arbeit jedes Verdichterkolbens unabhängig vom Arbeitsausgleich -des zugehörigen Motor-, Spülluftpumpen- und Pufferkolbens dadurch geschieht, daß im Verdichterzylinder auf der dem Verdichtungsraum abgelegenen Seite des Verdichterkolbens ein Pufferraum gebildet ist, der durch einen in seiner Zylinderwand nahe dem Beginn des Saughubes des Verdichterkolbens angeordneten, vom Verdichterkolben zu überlaufenden und nur bei Beginn des Verdichtersaughubes freigegebenen Schlitz mit der vor die Ansaugventile des Verdichters führenden Verdichtersaugleitung verbunden ist.Single-stage counter-rotating, free-floating piston compressor The invention relates to a single-stage internal combustion counter-rotating free-floating piston compressor in which the balance between the compression stroke and the return stroke Work of each compressor piston independent of the work balance of the associated one Motor, scavenging air pump and buffer piston happens that in the compressor cylinder a buffer space on the side of the compressor piston remote from the compression space is formed by one in its cylinder wall near the beginning of the suction stroke of the compressor piston arranged to be overflowed by the compressor piston and only at the beginning of the compressor suction stroke with the slot in front of the suction valves the compressor leading compressor suction line is connected.

Bei dem bekannten Verdichter jener Art führt die Verdichteransaugleitung durch den Verdichterpufferraum hindurch, nämlich über ein zusätzliches Rückschlagventil in ihn hinein und durch jenen Schlitz wieder aus ihm heraus, und erst danach vor die Ansaugventile des Verdichters. Dieser Umweg ist unerwünscht, denn das angesaugte Gas wird durch jenes lusätzliche Rückschlagventil und jenen Schlitz zusätzlich gedrosselt und durch den warmen Verdichterzylinder erwärmt, und dies beides vermindert den Wirkungsgrad des Verdichters. Die Erfindung soll das bessern.In the known compressor of this type, the compressor suction line leads through the compressor buffer space, namely via an additional check valve into it and out of it again through that slit, and only then forward the compressor suction valves. This detour is undesirable because that which is sucked in Gas is additionally throttled through that additional check valve and that slot and heated by the warm compressor cylinder, and both of these reduce the Efficiency of the compressor. The invention is intended to improve that.

Die Erfindung besteht darin, daß der vom Verdichterkolben im Verdichterzylinder gebildete Pufferraum mit der Verdichteransaugleitung nur durch den in der Zylinderwand des Pufferraums befindlichen, vom Verdichterkolben zu überlaufenden Schlitz, und zwar über eine Verbindungsleitung, verbunden ist.The invention consists in the fact that the compressor piston in the compressor cylinder Buffer space formed with the compressor suction line only through the one in the cylinder wall of the buffer space, the slit to be overflowed by the compressor piston, and is connected via a connecting line.

Die Zeichnung zeigt schematisch einen Längsschnitt durch eine Hälfte eines erfindungsgemäßen Verdichters. Darin bedeutet x-y die Symmetriemittellinie, 1 den Brennraum, 2 dessen Zylinder, 3 den Motorkolben, 4 dessen Kolbenstange, 5 den Spülluftpumpen- und Pufferkolben, 6 dessen Zylinder, 7 den Spülpumpenraum (seine Ventile sind nicht gezeichnet), 8 den Pufferraum, der die Rückwurfarbeit für den Motor- und den Spülpumpenkolben liefert, 9 die Kolbenstange für den Verdichterkolben, 10 deren Dichtung, 11 den Verdichterkolben, 12 den Verdichterzylinder, 13 den Pufferraum, der die Rückwurfarbeit für den Verdichterkolben liefert, 14 den Verdichtungsraum, 15 die Verdichteransaugleitung, 16 die Verdichteraustrittsleitung, 17 und 18 die Ansaug-bzw. Austrittsventile und 19 und 20 den Schlitz bzw. die Verbindungsleitung, die den Verdichterpufferraum mit der Ansaugleitung verbinden.The drawing shows schematically a longitudinal section through one half of a compressor according to the invention.
