Description
Gegenstand der Erfindung ist eine neuartige ' Anordnung der Ventile von Kompressoren, ; beispielsweise Kältemaschinen, durch welche die Entstehung eines übermäßig hohen Druckes zwischen Kolben und Zylinderdeckel, welcher eine Beschädigung des Zylinders herbeiführen könnte, mit größerer Sicherheit als durch bekannte Einrichtungen vermieden wird.The invention relates to a novel 'arrangement of the valves of compressors ; for example refrigerating machines, by means of which the creation of an excessively high pressure between the piston and the cylinder cover, which could cause damage to the cylinder, is avoided with greater certainty than by known devices.
Es ist bekannt, zu dem gleichen ZweckeIt is known for the same purpose
ι ο den das Druckventil tragenden Zylinderdeckel in solcher Weise verschiebbar anzuordnen und durch Federn zu belasten, daß er, wenn der Druck im Zylinder eine gewisse Grenze überschreitet, abgehoben und dadurch eine direkte Verbindung des Zylinderinnem mit der Druckleitung hergestellt wird. Die dadurch bewirkte Entlastung des Zylinders ist indessen verhältnismäßig gering. Um eine bessere Entlastung zu erzielen, werden gemäß vorliegender Erfindung Druck- und Saugventilkörper gemeinsam in solcher Weise gegen Feder wirkung verschiebbar angeordnet, daß durch ihre Verschiebung entgegen der Federwirkung eine Verbindung des Zylinderinnern mit der Saugleitung hergestellt wird. Die Zeichnung stellt den Erfindungsgegenstand in einem Ausführungsbeispiele in einem Längsschnitte durch die Ventile und die Steuerungskanäle dar. Der mittlere Teil des' Steuerungskörpers ist abgebrochen gezeichnet. Die Druckventile α der beiden Zylinderseiten haben die Form einfacher Platten, welche die Kanäle b, die durch den Kanal c an die Druckleitung angeschlossen sind, ab-.ι ο to arrange the cylinder cover carrying the pressure valve displaceably in such a way and to load it with springs that it is lifted off when the pressure in the cylinder exceeds a certain limit, thereby establishing a direct connection between the inside of the cylinder and the pressure line. The relief of the cylinder caused by this is, however, relatively small. In order to achieve better relief, according to the present invention pressure and suction valve body are arranged together in such a way against spring action displaceable that a connection of the cylinder interior with the suction line is made by their displacement against the spring action. The drawing represents the subject matter of the invention in an exemplary embodiment in a longitudinal section through the valves and the control channels. The middle part of the control body is shown broken off. The pressure valves α of the two cylinder sides have the shape of simple plates, which the channels b, which are connected to the pressure line through the channel c, from.
schließen. Die Saugventile sind als gleichachsig mit den Platten α angeordnete Ringe d j ausgebildet und wirken mit den an den Kanal e angeschlossenen Kanälen f zusammen. Die Wände der Ventilgehäuse und der Kanäle c und e bilden ein Stück, das durch die Schrauben g am Zylinderdeckel befestigt wird.conclude. The suction valves are designed as rings d j arranged coaxially with the plates α and interact with the channels f connected to the channel e. The walls of the valve housing and the channels c and e form one piece which is fastened to the cylinder cover by the screws g.
Die Teile h, welche die Ventilsitze enthalten, sind in Führungen i des gemeinsamen Steuerungskörpers in der Richtung der Ventilachsen verschiebbar und werden durch Federn k auf die Flächen I gepreßt. Tritt eine Ansammelung von Flüssigkeit im Zylinder ein, welche eine übermäßige Steigerung des Druckes im Zylinder zur Folge hat, so wird der Teil h an der betreffenden Zylinderseite gegen die Wirkung der Federn k von der Fläche I abgehoben und eine Verbindung des Zylinderinnem mit der Saugleitung e hergestellt, so daß eine schnelle Entlastung des Zylinders stattfinden kann.The parts h, which contain the valve seats, are displaceable in guides i of the common control body in the direction of the valve axes and are pressed onto the surfaces I by springs k. If there is an accumulation of liquid in the cylinder, which results in an excessive increase in the pressure in the cylinder, the part h on the relevant cylinder side is lifted from the surface I against the action of the springs k and the inside of the cylinder is connected to the suction line e produced so that a quick relief of the cylinder can take place.
Jedes der beiden Ventilpaare ist mit zwei Federn k verbunden, um' die Sicherheit der Federwirkung zu erhöhen. ·Each of the two pairs of valves is connected to two springs k in order to increase the safety of the spring action. ·
