Description
Die Erfindung betrifft einen Kompressorkolben, insbesondere für Kleinstkompressoren, wie diese beispielsweise als Reifenfüllkompressoren für Motorfahrzeuge Verwendung finden sollen. Es handelt sich also um 'Kompressoren, die wegen :der nur zeitweisen Benutzung in der Herstellung sehr billig sein müssen, trotzdem aber den an sie zu stellenden Forderungen durchaus genügen müssen. Ein sehr einfacher Kompressor läßt sich beispielsweise unter Anwendung des Zweitaktsystems mit 'Schlitzeinlaß unter Verwendung von einem Zylinder aus gezogenem Stahlrohr herstellen.The invention relates to a compressor piston, in particular for small compressors, such as these, for example, as tire inflation compressors for motor vehicles should find. So it is about 'compressors, which because of: the only temporarily Use must be very cheap to manufacture, but still the right to use them must definitely meet the requirements. A very simple compressor lets for example, using the two-stroke system with slot inlet Using a cylinder made from drawn steel tubing.
Schwierigkeiten treten beim Kompressor bezüglich der Verkantung des Kolbens auf. Diese Schwierigkeiten wenden erfindungsgemäß -dadurch behoben, daß der Kolben mittels einer an ihm angeordneten Kugelpfanne unmittelbar auf dem entsprechend kugelig ausgebildeten Ende der Pleuelstange aufsitzt unter Benutzung einer an sich bekannten Kugelverschlußscheibe. Es genügt aber nicht, besonders dann, wenn der Kolben verhältnismäßig geringe Länge hat, den Kolben lediglich auf dieser kurzen Länge zu führen, da durch sein Kippen sonst ein Fressen an der Zylinderwandung eintreten würde. Es wird deshalb erfindungsgemäß an dem rückwärtigen Ende des Kolbens eine zusätzlicheFührung vorgesehen, die radial zum Kolben eine gewisse Nachgiebigkeit besitzt. Diese Nachgiebigkeit in radialer Richtung kann beispielsweise durch eine Manschette aus Leder od. dgl. nachgiebigem Werkstoff erreicht werden. Diese Manschette aus Leder hat den weiteren Vorteil, daß man auf eine besondere Schleuderölung von der umlaufenden Kurbel her verzichten kann, wenn die Manschette mit einem Schmiermittel getränkt ist.Difficulties arise with the compressor with regard to the tilting of the Piston open. According to the invention, these difficulties are resolved in that the piston by means of a ball socket arranged on it directly on the corresponding spherical end of the connecting rod is seated using a per se known ball locking disc. But it is not enough, especially if the Piston has a relatively short length, the piston only on this short one Length to lead, as otherwise seizing occur on the cylinder wall through its tilting would. It is therefore according to the invention at the rear end of the piston a additional guide provided, which radially to the piston a certain flexibility owns. This flexibility in the radial direction can, for example, by a Cuff made of leather od. Like. Resilient material can be achieved. This cuff leather has the further advantage that you can rely on a special centrifugal oiling of the rotating crank can be dispensed with if the cuff is coated with a lubricant is soaked.
Zur Erläuterung der Erfindung ist ein nach dem Zweitaktsystem arbeitender Kleinstkompressor im Längsschnitt dargestellt.To explain the invention is a working according to the two-stroke system Small compressor shown in longitudinal section.
Der Kolben 2 von verhältnismäßig geringer Länge, welcher übliche Kolbenringe 8 trägt, hat eine Kugelpfanne i. Die Pleuelstange 4 trägt an ihrem Kolbenende eine Kugel 3, die in der Kugelpfanne i eingelagert ist. Die Kugel wird gehalten durch eine Kugelverschlußscheibe 6 in üblicher Weise. In einer gewissen Entfernung vom Kolben ist rückwärtig die zusätzliche Führung angeordnet, und zwar im Falle des Ausführungsbeispieles eine Manschette 5 aus Leder, die zwischen zwei Scheiben 9 und io gehalten ist, welche letztere mit dem Kolbenkörper :2 über auf -dem Umfang gleichmäßig verteilte Distanzbolzen ii verbunden sind.The piston 2 of relatively short length, which conventional piston rings 8 carries, has a ball socket i. The connecting rod 4 carries a at its piston end Ball 3, which is stored in the ball socket i. The ball is held through a ball locking disk 6 in the usual way. At a certain distance from the Piston is arranged at the rear of the additional guide, in the case of the Embodiment a sleeve 5 made of leather, which is between two discs 9 and io is held, the latter with the piston body: 2 over on the circumference evenly distributed spacer bolts ii are connected.
Zum Einführen der Kugel 3 in die Verschlußscheibe 6 besitzt diese einen radialen Schlitz 7, dessen Breite mindestens die Breite s des Pleuelstangensteges aufweist.To introduce the ball 3 into the closure disk 6, the latter has it a radial slot 7, the width of which is at least the width s of the connecting rod web having.
Die Ledermänschette 5 ist mit einem geeigneten Schmiermittel imprägniert.The leather cuff 5 is impregnated with a suitable lubricant.
