Description

Einrichtung zur Regelung des Kühlwasserstromes durch einen Thermostaten, insbesondere für Brennkraftmaschinen Die Erfindung bezieht sich auf eine Regelungsvorrichtung für Kühleinrichtungen, insbesondere für Brennkraftmaschinen, bei welcher der Umlauf des Kühlwassers durch einen Thermostaten derart geregelt wird, daß bei niedriger Temperatur beispielsweise der Zufluß des Wassers zum Kühler gedrosselt oder abgesperrt ist und das Wasser durch eine ständig offene, parallel zum Kühler liegende Zweigleitung unmittelbar in die vom Kühler wegführende Leitung :abfließt.Device for regulating the cooling water flow through a thermostat, in particular for internal combustion engines The invention relates to a control device for cooling devices, in particular for internal combustion engines, in which the circulation the cooling water is regulated by a thermostat so that at lower Temperature, for example, the flow of water to the cooler throttled or shut off and the water through a permanently open branch line parallel to the radiator directly into the line leading away from the cooler: flows away.

Gemäß der Erfindung wird nun an der Stelle, wo die genannte Zweigleitung von dem zum Thermostaten und Kühler führenden Leitungsstrang abzweigt, verengt, beispielsweise nach Art eines Venturirohres, etwa in der Art, daß bei geöffnetem Thermostat an der Stelle, wo die Umlaufleitung in das Hauptwasserrohr mündet, ein Unterdruck entsteht, welcher ein Abfließen des Wassers aus der vor dem Thermostaten befindlichen Zufiußleitung unmittelbar in die Umlaufleitung verhindert oder doch erschwert.According to the invention, at the point where said branch line branches off from the wiring harness leading to the thermostat and cooler, narrows, for example in the manner of a Venturi tube, for example in the manner that when it is open Thermostat at the point where the circulation line joins the main water pipe Underpressure arises, which causes a drainage of the water from the front of the thermostat Prevents the supply line located directly into the circulation line or at least difficult.

In der Zeichnung ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Es ist a der Kühler, an welchen oben in üblicher Weise die vom Motor kommende Kühlwasserleitung b angeschlossen ist. c ist die nach dem Motor abführende Leitung für. das gekühlte Wasser. In der Zuleitung b ist ein Thermostat d eingebaut, der die Leitung bei niedriger Temperatur des Kühlmittels drosselt und absperrt. Vor dem Thermostat ist die Leitung bei e etwa nach Art eines V enturirohres verengt und durch eine an dieser Stelle einmündende Zweigleitung/ von beispielsweise geringem Querschnitt mit der Rückleitung c verbunden.In the drawing is an embodiment of the inventive concept shown. It is a the radiator, on which the engine from the top in the usual way incoming cooling water line b is connected. c is the one discharging after the engine Line for. the chilled water. A thermostat d is installed in supply line b, which throttles and shuts off the line when the coolant temperature is low. In front of the thermostat, the line is narrowed at e roughly in the manner of a V enturi tube and by a branch line opening at this point / of, for example, a small one Cross section connected to the return line c.

Die Wirkungsweise ist aus dem Vorhergehenden ohne weiteres verständlich. Der Thermostat könnte auch z. B. in der Zweigleitung angeordnet und die Zuleitung zum Kühler an eine verengte Stelle der Zweigleitung angeschlossen sein. Auch könnte letztere zur Vermeidung von Wärmeverlusten entsprechend ausgebildet, z.B. mit doppelter Wandung o. dgl. versehen, sein. Statt von unten kann die Zweigleitung l von der Seite oder von oben an die engste Stelle des Kühlwasserzuleitungsrohres geführt werden.The mode of operation is readily understandable from the foregoing. The thermostat could also e.g. B. arranged in the branch line and the supply line connected to the cooler at a narrowed point in the branch line. Also could the latter designed accordingly to avoid heat loss, e.g. with double Wall o. The like. Provided, be. Instead of from below, the branch line l can be taken from the Side or from above to the narrowest point of the cooling water supply pipe will.
