Description

Quecksilberdampfstrahlpumpe. Bei Quecksilberdampfstrahlpumpen ist es bekannt, bei unzulässiger Druckerhöhung des Dampfes das Quecksilber in einem U-förmigen Rohr bis zum Scheitelpunkt steigen zu lassen, wodurch es die Heizung abstellt. Das Neue der Erfindung besteht darin, daß zwecks Einstellens der Abstellvorrichtung auf einen gewünschten Druck das U-förmige Rohr in dem Quecksilber verstellt werden kann. Auf der Zeichnung ist eine Ausführungsform der Pumpe veranschaulicht.Mercury vapor jet pump. With mercury vapor jet pumps is it is known that the mercury in an unacceptable pressure increase of the steam Let the U-shaped pipe rise to the apex, making it the heater turns off. The novelty of the invention is that for the purpose of adjusting the parking device the U-shaped tube in the mercury can be adjusted to a desired pressure can. An embodiment of the pump is illustrated in the drawing.

In den Heizraum a der Pumpe ragt ein Barometerrohr i hinein, dessen offener, umgebogener Schenkel in einen Vorratsbecher w für Quecksilber mündet. In diesem Becher w hängen ferner die unteren U-förmigen Schenkel einer Rohrgabel v, deren obere U-förmigen Schenkel die Leitung der Gasheizung bilden. Steigt nun der Druck in der Pumpe über den normalen Druck, so steigt das Quecksilber in den unteren U-förmigen Schenkeln der Rohrgabel v bis zum Scheitelpunkt, so daß es den Scheitel der oberen U-förmigen Schenkel bedeckt und dadurch die Gaszufuhr (von einer kleinen Stichflamme abgesehen) unterbindet. Die Rohrgabel v ist in dem Behälter w längsverschieblich angeordnet, so daß der Scheitelpunkt in verschiedene Höhenlagen gebracht werden kann, wodurch es erreicht wird, daß der Druck, bei dem die Abstellung der Heizung erfolgen soll, beliebig eingestellt werden kann.A barometer tube i protrudes into the boiler room a of the pump open, bent leg opens into a storage cup w for mercury. In this cup w also hang the lower U-shaped legs of a pipe fork v, whose upper U-shaped legs form the line for the gas heater. Now increases the Pressure in the pump above normal pressure, the mercury rises in the lower U-shaped legs of the pipe fork v up to the apex, so that it is the apex of the upper U-shaped leg and thereby the gas supply (from a small Apart from a jet flame). The pipe fork v is longitudinally displaceable in the container w arranged so that the apex can be brought to different altitudes can, whereby it is achieved that the pressure at which the shutdown of the heating should take place, can be set as required.

Bei Verwendung anderer Heizmittel als Gas zur Heizung der Pumpen wird die Regulierung der Heizmitteläufuhr durch entsprechende Ausführung der Erfindung gewährleistet, bei elektrischer Heizung z. B. durch ein Relais.When using heating media other than gas to heat the pumps the regulation of the heating medium flow through a corresponding embodiment of the invention guaranteed, with electric heating z. B. by a relay.

Claims (1)

PATENTANSPRUCH: Quecksilberdampfstrahlpumpe, deren Quecksilber bei unzulässiger Drucksteigerung bis zum Scheitelpunkt eines U-förmigen Rohres hochsteigt und dadurch die Heizung abstellt, dadurch gekennzeichnet, daß das U-förmige Rohr in der Längsrichtung verschieblich ist, wodurch die Abstellung der Heizung entsprechend dem gewünschten Dampfdruck beliebig eingestellt werden kann. PATENT CLAIM: Mercury vapor jet pump, the mercury of which rises to the apex of a U-shaped pipe in the event of an impermissible increase in pressure and thereby switches off the heating, characterized in that the U-shaped pipe can be moved in the longitudinal direction, whereby the heating can be switched off according to the desired vapor pressure can be.
