Description

Selbsttätig regulierende Drosselvorrichtung, in der Hauptsache für Kälteanlagen Die Erfindung bezweckt, bei selbsttätig regulierenden Drosselvorrichtungen die bisher übliche Platten- und Rohrmembrane wegen ihrer beschränkten Beweglichkeit bzw. Hubes und der sich daraus ergebenden Gefahr des Erlahmens bei Einstellung eines größeren Leistungsbereiches durch ein zuverlässiges und praktisch nicht erlahmendes Steuerungsorgan zu ersetzen. In einem beiderseitig offeneu Zylinder bewegt sich reibungslos ein federbelasteter Kolben, der die I-Iochdruckseite stopfbüchsar tig von der Niederdruckseite trennt, als Ventilsitz ausgebildet ist und als einziges federbelastetes Steuerungsorgan sich gegen den festen Ventilkegel legt und so den Dur chgangsspalt direkt steuert. Vorhandene Und,ichtigkeiten stören den Betrieb nicht, im Gegenteil wird durch sie ein Vereisen und Festklemmen des Kolbens im Zylinder vermieden; Auch wirkt er dadurch bereits als Reduzierorgan für eine kleine Menge,: während die fehlende Menge durch den Ventilspalt reguliert wird. Infolge der kleinen w irksamen Kolbenfläche gegenüber der großen wirksamen Membranfläche. kann die 'Neukonstruktion vorteilhaft für hohe Drücke, beispielsweise in Kohlensäure-Kälteanlagen, verwendet werden, was bisher so ohne weiteres nicht möglich war.Self-regulating throttle device, mainly for Refrigeration systems The invention aims at automatically regulating throttle devices the previously common plate and tube membrane because of their limited mobility or stroke and the resulting risk of flagging when hiring a greater performance range through a reliable and practically non-flagging one To replace control organ. Moves in a cylinder open on both sides smoothly a spring-loaded piston that the high pressure side of the stuffing box separates from the low-pressure side, is designed as a valve seat and is the only one spring-loaded control element lies against the fixed valve cone and so the The passage gap controls directly. Existing and imperfections interfere with operation not, on the contrary, they freeze up and jam the piston in the cylinder avoided; It also acts as a reducing organ for a small amount: while the missing amount is regulated by the valve gap. As a result of the small effective piston area compared to the large effective membrane area. can the 'new design used advantageously for high pressures, for example in carbon dioxide refrigeration systems what was previously not possible without further ado.

In der Zeichnung ist ein Ausführungsbeispiel im Längsschnitt dargestellt. In einem Zylinder a ist ein plunderartig ausgebildeter; federbelasteter Kolben b angeordnet, der als beweglicher Ventilsitz ausgebildet ist. Auf der Hochdruckseite sitzt ein fester Ventilkegel c, auf der Niederdruckseite eine zylindrische Druckfeder d, die gegebenenfalls auch verstellbar eingerichtet werden kann.In the drawing, an embodiment is shown in longitudinal section. In a cylinder a is a plunder-like; spring loaded piston b arranged, which is designed as a movable valve seat. On the high pressure side there is a fixed valve cone c and a cylindrical compression spring on the low-pressure side d, which can optionally also be set up to be adjustable.

Der auf der Hochdruckseite befindliche Druck entspricht der Sun -tine des Federdruckes. und des auf der Niederdruckseite eingestellten Druckes. Sinkt der eingestellte Niederdruck, so überwiegt der Hochdruck und öffnet den Ventilspalt. Steigt der eingestellte Niederdruck, so überwiegt dieser und schließt den Ventilspalt.The pressure on the high pressure side corresponds to the Sun -tine of the spring pressure. and the pressure set on the low pressure side. Sinks the set low pressure, the high pressure prevails and opens the valve gap. If the set low pressure increases, it predominates and closes the valve gap.
