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 invention relates to a thermostat valve for a coolant flow with a first, responsive to the temperature of the coolant thermostatic working element and with a second, electrically heatable thermostatic working element, both of which 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 thermostatischen 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.In thermostatic valves of the type mentioned, it is known to provide for the first, responsive to the coolant temperature thermostatic working element an abutment for the working piston, which is formed by the working piston of the second thermostatic working element. The valve element is changed in this type both by the first thermostatic working element and by the second thermostatic working element when it is acted upon by electrical energy. As soon as the first thermostatic working element has responded to the temperature of the coolant and has moved the valve element, it is no longer possible by means of the heatable thermostatic working element to exactly approach a position predetermined by a control or regulation, since 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 genannten Art so auszubilden, dass jederzeit durch Zufuhr von elektrischer Energie zu dem elektrisch beheizbaren thermostatischen Arbeitselement vorgegebene Positionen des Ventilelementes angefahren werden können.The invention has the object of providing a thermostatic valve of the type mentioned in such a way that at any time by supplying electrical energy to the electrically heatable thermostatic working element predetermined positions of the valve element can be approached.
Diese Aufgabe wird mit den Merkmalen von Anspruch 1 gelöst.This object is achieved with the features of claim 1.
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.As a result of the construction according to the invention, it is achieved that the adjusting movements of the valve element caused by the first thermostatic working element and by the second thermostatic working element do not add up. If the adjustment movement intended by the electrically heatable working element is less than the adjusting movement which caused the first thermostatic working element as a function of the temperature of the coolant, the valve element remains in the position determined by the first thermostatic working element. If the adjusting movement dependent on the temperature of the coolant through the first thermostatic working element is smaller than the adjusting movement caused by the electrically heatable working element, the valve element is brought into the position determined by the electrical energy.
