Abstract
Description
Die Erfindung betrifft ein Thermostatventil für eine Kühlmittelströmung mit einem ersten, auf die Temperatur des Kühlmittels reagierenden thermostatischen Arbeitselement und mit einem zweiten, elektrisch beheizbaren thermostatischen Arbeitselement, die beide zum Verstellen von wenigstens einem gemeinsamen Ventilelement dienen.The The invention relates to a thermostat valve for a coolant flow with a first, on the temperature of the coolant reacting thermostatic working element and with a second, electrically heatable thermostatic working element, both serve to adjust at least one common valve element.
Bei Thermostatventilen der eingangs genannten Art ist es bekannt, für das erste, auf die Kühlmitteltemperatur reagierende thermostatische Arbeitselement ein Widerlager für dessen Arbeitskolben vorzusehen, das von dem Arbeitskolben des zweiten thermostatischen Arbeitselementes gebildet wird. Das Ventilelement wird bei dieser Bauart sowohl von dem ersten thermostatischen Arbeitselement als auch von dem zweiten thermostatischen Arbeitselement verändert, wenn dies mit elektrischer Energie beaufschlagt wird. Sobald das erste thermostatische Arbeitselement auf die Temperatur des Kühlmittels angesprochen hat und das Ventilelement bewegt hat, ist es mittels des beheizbaren thermostati schen Arbeitselementes nicht mehr möglich, eine von einer Steuerung oder Regelung vorgegebene Position exakt anzufahren, da sich die Bewegungen aufgrund des ersten thermostatischen Arbeitselementes und des elektrisch beheizbaren zweiten thermostatischen Arbeitselementes überlagern.at Thermostatic valves of the type mentioned above it is known for the first, to the coolant temperature Reactive thermostatic working element an abutment for its Provide working piston, which from the working piston of the second thermostatic Work element is formed. The valve element is at this Design of both the first thermostatic working element as well changed by the second thermostatic working element when this is supplied with electrical energy. As soon as the first thermostatic working element addressed to the temperature of the coolant has moved and the valve element, it is by means of the heated Thermostati rule working element no longer possible, one of a control or regulation predetermined position to approach exactly because the Movements due to the first thermostatic working element and superimpose the electrically heatable second thermostatic working element.
Der Erfindung liegt die Aufgabe zugrunde, ein Thermostatventil der eingangs genannte Art so auszubilden, dass jederzeit durch Zufuhr von elektrischer Energie zu dem elektrisch beheizbaren thermostatischen Arbeitselementes vorgegebene Positionen des Ventilelementes angefahren werden können.Of the Invention is based on the object, a thermostatic valve of the beginning so-called type in such a way that at any time by supply of electrical Energy to the electrically heatable thermostatic working element predetermined positions of the valve element can be approached.
Diese Aufgabe wird dadurch gelöst, dass das erste thermostatische Arbeitselement an einem stationärem Widerlager abgestützt ist und dass ein Übertragungsglied vorgesehen ist, das unter Umgehen des Widerlagers zwischen dem Ventilelement und dem zweiten thermostatischen Arbeitselement angeordnet ist.These Task is solved by that the first thermostatic working element on a stationary abutment supported is and that a transmission link is provided, bypassing the abutment between the valve element and the second thermostatic working element is arranged.
Durch die erfindungsgemäße Ausbildung wird erreicht, dass die von dem ersten thermostatischen Arbeitselement und von dem zweiten thermostatischen Arbeitselement verursachten Verstellbewegungen des Ventilelementes sich nicht addieren. Sofern die von dem elektrisch beheizbaren Arbeitselement beabsichtigte Verstellbewegung geringer ist als die Verstellbewegung, die das erste thermostatische Arbeitselement abhängig von der Temperatur des Kühlmittels verursacht hat, bleibt das Ventilelement in der von dem ersten thermostatischen Arbeitselement bestimmten Position. Falls die von der Temperatur des Kühlmittels abhängige Verstellbewegung durch das erste thermostatische Arbeitselement kleiner ist als die von dem elektrisch beheizbaren Arbeitselement verursachte Verstellbewegung, so wird das Ventilelement in die von der elektrischen Energie bestimmte Position gebracht.By the training of the invention will achieved that of the first thermostatic working element and caused by the second thermostatic working element Adjustment movements of the valve element do not add up. Provided intended by the electrically heatable working element Adjustment movement is less than the adjustment, which is the first thermostatic working element depending on the temperature of the refrigerant caused the valve element remains in the first of the thermostatic Work item specific position. In case of the temperature of the coolant dependent Adjusting movement through the first thermostatic working element smaller than that of the electrically heated working element caused adjustment movement, the valve element is in the of the electrical energy certain position.
