Description

Die Erfindung betrifft einen gasbelasteten, kolbenlosen Druekölspeicher mit zum Schutz gegen Gasaufnahme des Drucköls zwischen Gas und Drucköl vorgesehener Flüssigkeitstrennschicht.The invention relates to a gas-loaded, piston-less pressure oil reservoir with for protection against gas absorption of the pressurized oil between the gas and the pressurized oil.

Es ist bei druckluftbelasteten Druckflüssigkeitsspeichern bekannt, die Druckflüssigkeit im Speicher gegen Luftaufnahme dadurch zu schützen, daß zwischen Druckflüssigkeit und Luftraum eine gegen Luftaufnahme unempfindliche Trennflüssigkeit vorgesehen wird. Bei Druckölspeichern besteht in dieser Hinsicht die Schwierigkeit, daß das spezifische Gewicht der in Betracht kommenden Trennflüssigkeiten, z. B. von Wasser, nicht zwischen denen der Druckluft und des Drucköls liegt, weshalb die drei Stoffe in der gewünschten Reihenfolge nicht unmittelbar übereinander geschichtet werden können.It is known in the case of pressurized fluid accumulators loaded with compressed air to counteract the pressurized fluid in the accumulator To protect air intake, that between pressure fluid and air space an against air intake insensitive separating liquid is provided. In the case of pressurized oil accumulators, this is the case the difficulty that the specific gravity of the separation liquids in question, e.g. B. from Water, not between that of the compressed air and the pressure oil, which is why the three substances in the desired Order cannot be layered directly on top of each other.

Gemäß der Erfindung ist diese Schwierigkeit bei Speichern der eingangs genannten Art dadurch umgangen, daß im Speicher eine beiderseits einer festen Trennwand kommunizierend verbundene Trennvorlage von gesättigtem Salzwasser vorgesehen ist, welche auf einer Seite der Trennwand vom Gas und auf der anderen Seite vom Drucköl beaufschlagt ist.According to the invention, this difficulty is circumvented in the case of memories of the type mentioned at the beginning, that in the memory a separating template communicatingly connected on both sides of a solid partition of saturated salt water is provided, which is on one side of the partition from the gas and on the other Side is acted upon by the pressure oil.

In Weiterbildung der Erfindung dient als Trennwand ein mit einer öffnung in die Salzwasservorlage hineinragender dünnwandiger z. B. rohrförmiger Behälter, dessen Inneres den Druckölraum bildet.In a further development of the invention, a partition with an opening in the salt water reservoir serves as a partition protruding thin-walled z. B. tubular container, the interior of which forms the pressure oil chamber.

Um unerwünschte Durchmischungen beim Zufluß von Drucköl zu vermeiden, ist zweckmäßig ein Ablenkblech am Druckölanschluß vorgesehen.In order to avoid undesirable mixing when the pressure oil flows in, it is advisable to use a deflector provided at the pressure oil connection.

In der Zeichnung ist ein Druekölspeicher in schematischem Längsschnitt dargestellt, bei dem die vorstehend beschriebene Erfindung verwirklicht ist.In the drawing, a Druekölspeicher is shown in a schematic longitudinal section, in which the above described invention is realized.

Die druckfeste Außenwand 1 des Speichers ist durch den ebenfalls druckfesten Deckel 2 abgeschlossen. An diesem ist ein nach unten offenes dünnwandiges Rohr 3 angeschlossen oder luftdicht befestigt, dessen Rauminhalt etwa halb so groß wie der des ganzen Speichers ist. Innerhalb dieses Rohres befindet sich das Drucköl 4, während der übrige Speicherraum mit gesättigtem Salzwasser 5 gefüllt ist, das über Druckluft 6 das Drucköl 4 aus dem dünnwandigen Rohr 3 in die zu bedienende Anlage preßt. Im Deckel 2 sind die hierfür erforderlichen Anschlüsse 7 und 8 für Drucköl bzw. Druclduft vorgesehen. Durch das unterhalb des Anschlusses 7 für das Drucköl am Deckel 2 angebrachte Ablenkblech 9 wird vermieden, daß beim Zurückpumpen des Drucköls in den Speicher turbulente Strömungen entstehen, die sich fortpflanzend auf den Spiegel des Salzwassers übertragen und die glatte Trennung der beiden Flüssigkeiten stören könnten.The pressure-resistant outer wall 1 of the storage tank is closed off by the pressure-resistant cover 2 . A thin-walled tube 3, which is open at the bottom, is connected or airtightly attached to this, the volume of which is approximately half as large as that of the entire memory. Inside this pipe there is the pressurized oil 4, while the rest of the storage space is filled with saturated salt water 5 , which presses the pressurized oil 4 out of the thin-walled pipe 3 into the system to be operated via compressed air 6. The connections 7 and 8 required for this are provided in the cover 2 for pressurized oil and pressurized air. The deflector 9 attached below the connection 7 for the pressurized oil on the cover 2 prevents turbulent currents from being created when the pressurized oil is pumped back into the reservoir, which can be propagated to the level of the salt water and disrupt the smooth separation of the two liquids.

Etwas oberhalb des unteren Randes des Rohres 3 ist Gasbelasteter, kolbenloser DruekölspeicherSlightly above the lower edge of the pipe 3 is gas-loaded, piston-free pressure oil reservoir

an der Innenseite der Außenwand 1 der elektrische Kontakt 10 für die ölstandsanzeige vorgesehen. Dieser bewirkt eine Stromunterbrechung, wenn das leitende Salzwasser an dieser Stelle von einem Druckluftpolster abgelöst wird, und ist so geschaltet, daß eine weitere Druckölentnahme aus dem Speicher unmöglich gemacht wird. Durch diese Sicherungseinrichtung wird ein unerwünschtes Eindringen der Salzwasservorlage in die Anlage der ölhydraulik verhindert.on the inside of the outer wall 1, the electrical contact 10 is provided for the oil level indicator. This causes a power interruption if the conductive salt water is replaced by a compressed air cushion at this point, and is switched in such a way that it is impossible to take any further pressurized oil from the reservoir. This safety device prevents unwanted penetration of the salt water seal into the hydraulic system.
