Description
Regelvorrichtung für die Kühlmitteltemperatur bei Brennkraftmaschinen Bei bekannten Regelvorrichtungen für die Kühlmitteltemperatur bei Brennkraftmaschinen mit einer zur Umlaufpumpe führenden Zweigleitung wird der Zustrom des Kühlmittels zur Kühleinrichtung durch einen Thermostaten derart geregelt, daß das Öffnen und Schließen des Ventils einer zur Umlaufpumpe führenden Zweigleitung gleichzeitig, und zwar zwangläufig, mit dem Öffnen und Schließen des Ventils des Hauptkanals zur Kühleinrichtung geschieht.Control device for the coolant temperature in internal combustion engines In known regulating devices for the coolant temperature in internal combustion engines with a branch line leading to the circulation pump, the inflow of the coolant to the cooling device controlled by a thermostat so that the opening and Closing the valve of a branch line leading to the circulation pump at the same time, inevitably, with the opening and closing of the valve of the main channel for Cooling device happens.
Die bekannten Regler dieser Art haben den Nachteil, daß beide Ventile zwangläufig durch den Thermostaten gesteuert werden, wodurch nicht nur Schwierigkeiten in der Einstellung der Ventile, sondern auch Gefahren für die Maschine bei Versagen des Reglers eintreten können.The known regulators of this type have the disadvantage that both valves inevitably be controlled by the thermostat, which not only creates difficulties in the setting of the valves, but also dangers to the machine in the event of failure of the controller can occur.
Bei anderen bekannten Reglern ist das thermostatisch gesteuerte Regelorgan so ausgebildet, daß dem thermostatisch steuerbaren Durchlaßquerschnitt ein zweiter von Hand einstellbarer Querschnitt nebengeordnet ist.In other known regulators, the regulating element is thermostatically controlled designed so that the thermostatically controllable passage cross-section a second manually adjustable cross-section is secondary.
Gegenstand der Erfindung ist nun eine Regelungsvorrichtung, welche lediglich das Hauptventil zum Kühler thermostatisch steuert, während das Ventil der zur Umlaufpumpe unter Umgehung des Kühlers direkt oder indirekt führenden Zweigleitung unabhängig von dem Thermostaten je nach dem Druck des Kühlmittels den Durchfluß zur Pumpe selbsttätig freigibt bzw. abschließt.The invention now relates to a control device which only the main valve to the radiator thermostatically controls while the valve the branch line leading directly or indirectly to the circulation pump bypassing the cooler the flow rate independently of the thermostat depending on the pressure of the coolant to the pump automatically releases or closes.
Auf der Zeichnung ist der Erfindungsgegenstand schematisch dargestellt.The subject of the invention is shown schematically in the drawing.
In dem Wassermantel a befindet sich ein Thermostat b, der durch eine Spindel c mit einem den Zufluß zum Kühler steuernden Ventil d verbunden ist. Der Thermostat b ist an seinem hinteren Ende durch einen Armstern e -an dem Wassermantel a befestigt. Der Wassermantel a ist ferner durch einen Ausflußstutzen f mit der Zweigleitung verbunden. In diesem Stutzen f ist ein einstellbares überdruckventil g mit Feder h angebracht.In the water jacket a there is a thermostat b which is connected by a spindle c to a valve d which controls the flow to the cooler. The thermostat b is attached at its rear end by an arm star e -an the water jacket a. The water jacket a is also connected to the branch line by an outflow nozzle f. An adjustable pressure relief valve g with spring h is fitted in this connection piece f.
Solange das Kühlmittel eine gewisse Temperatur noch nicht erreicht hat, bleibt das Ventil d geschlossen. Wird dabei der Druck im Wassermantel, insbesondere beispielsweise beim Anlassen des Motors durch den erhöhten Druck des Kühlmittels, zu groß, so öffnet sich das Überdruckventil g, welches mit einer Feder h für jeden Druck einstellbar ist.As long as the coolant has not yet reached a certain temperature valve d remains closed. When doing this, the pressure in the water jacket, in particular for example when starting the engine due to the increased pressure of the coolant, too large, the pressure relief valve g opens, which has a spring h for each Pressure is adjustable.
Das Überdruckventil g regelt sich also je nach Druck des Kühlmittels selbsttätig ohne Einwirkung des Thermostaten b. Wird eine bestimmte Temperatur, auf welche der Thermostat b eingestellt ist, überschritten, so öffnet er infolge seiner Ausdehnung das Ventil d, während das Überdruckventil g sich selbsttätig infolge des Nachlassens des Druckes schließt.The pressure relief valve g regulates itself depending on the pressure of the coolant automatically without the action of the thermostat b. If a certain temperature to which the thermostat b is set, exceeded, it opens as a result its expansion the valve d, while the pressure relief valve g automatically as a result the release of the pressure closes.
Statt der Ventile d und g können auch andere bekannte Abschlußorgane, z. B. Schieber, Drosselklappen o. dgl., zur Anwendung kommen.Instead of the valves d and g, other known closing organs, z. B. slide, throttle valve o. The like., Are used.
