Description
"Mischventil mit einem Dehnstoffregler zur Regelung der Kühlmitteltemperatur" Die Erfindung betrifft ein Mischventil mit einem Dehnstoffregler zur Regelung der Kilhlmitteltemporatur im Kühlmittel-Kreislauf an Kraftfahrzeug-Brennkraftmaschinen mit einer vom Wärmetauscher aus in den Regelraum des Mischventils führenden SUhlmittelleltung, einer deh Wärmetauscher umgehenden Kurzschlußleitung und einer an die Kühlwasserpumpe angeschlossenen Durchflußlei tung. "Mixing valve with an expansion regulator to regulate the coolant temperature" The invention relates to a mixing valve with an expansion regulator for regulating the Coolant temperature in the coolant circuit on motor vehicle internal combustion engines with a refrigerant line leading from the heat exchanger into the control room of the mixing valve, a short-circuit line bypassing the heat exchanger and one to the cooling water pump connected flow line.
Die bekannten kurzschlußsteuernden Kühlwasserregler oder Drei-Wege-Mischventile sind zur Regelung der Khlmitteltemperatur mit einem Dehnstoffregler versehen1 der zwischen zwei Ventiltellern im Regelraum des Drei-Wege-Mischventiles angeordnet ist.The well-known short-circuit controlling cooling water regulators or three-way mixing valves are equipped with an expansion regulator to regulate the coolant temperature1 the arranged between two valve disks in the control room of the three-way mixing valve is.
Diese Anordnung gewährl-eist.t keine einwandfreie Umströmung des Dehnstoffreglers aufgrund der störend wirkenden Ventilteller.This arrangement does not guarantee a perfect flow around the expansion regulator due to the annoying valve disc.
Der Erfindung liegt die Aufgabe zugrunde, d-n Nachteil durch ein besonders einfaches, allen Anforderungen gerecht werdendes Mischventil zu beseitigen.The invention is based on the object of a particular disadvantage to eliminate simple mixing valve that meets all requirements.
Die gestellte Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Dehnstoffregler vom Mischventil in die Durchflußleitung abragend am Mischventil angeordnet ist.The object set is achieved according to the invention in that that the expansion regulator protruding from the mixing valve into the flow line on the mixing valve is arranged.
In- vorteilhafter Ausgestaltung der Erfindung kann hinter dem Regelraum in der Durchflußleitung eine an den Kreislauf angeschlossene Heizleitung vorgesehen sein.In an advantageous embodiment of the invention, behind the control room a heating line connected to the circuit is provided in the flow line be.
In der nachstehenden Zeichnung ist ein Ausführungsbeispiel des Gegenstandes der Erfindung dargestellt. Es zeigen Fig. 1 eine schematische Darstellung des Kühlmittelkreislaufes einer Brennkraftmaschine und Fig. 2 eine Schnittdarstellung des Mischventiles.In the drawing below is an embodiment of the subject of the invention shown. 1 shows a schematic representation of the coolant circuit an internal combustion engine and FIG. 2 shows a sectional view of the mixing valve.
Der Kühlmittelkreislauf gemäß Fig. 1 ist im wesentlichen mit einem Mischventil 1 versehen. Aus einer vom Mischventil 1 abzweigenden Durchflußleitung 2 wird ein KUhimittel von einer in der Zeichnung nicht dargestellten Kühlwasserpumpe in den Motoreintritt 3 einer Brennkraftmaschine 4 gepumpt. Das in den Kühl.The coolant circuit according to FIG. 1 is essentially with a Mixing valve 1 provided. From a flow line branching off from the mixing valve 1 2 is a cooling means from a cooling water pump, not shown in the drawing pumped into the engine inlet 3 of an internal combustion engine 4. That in the cool.
mittelräumen der Brennkraftmaschine 4 aufgeheitzte Kühlmittel fließt durch eine am Motoraustritt 5 angeschlossene Leitung 6 zu einem Wärmetauscher 7, vom Wärmetauscher 7 aus durch eine Kilhlmittelleitun6 8 zum Mischventil 1 und/oder durch eine von der leitung 6 abzweigende, den Wirmetauscher 7 umgehende Kurzschlußleitung 9 zum Mischventil 1. Eine Hoisleitung 10 ist an dem Mischventil 1 angeschlossen.Central spaces of the internal combustion engine 4 heated coolant flows through a line 6 connected to the engine outlet 5 to a heat exchanger 7, from the heat exchanger 7 through a Kilhlmittelleitun6 8 to the mixing valve 1 and / or by a short-circuit line branching off from the line 6 and bypassing the hot-air exchanger 7 9 to the mixing valve 1. A heating line 10 is connected to the mixing valve 1.
Das in Fig. 2 vergrdert dargestellte Mischventil 1 ist in einem mit mehreren AnschJUssen für die Kühlmittelleitung 8, Kurzschlußleitung 9, Heizleitung 10 und Durchflußleitung 2 versehenen Gehäuse 11 angeordnet, weiches durch zwei Gehäuseteile lla und lib gebildet ist, die in abgedichteter Form mit einem Dichtungsring 12 miteinander verbunden sind. Das Mischventil 1 besteht aus zwei durch einen Kolben 13 axial bewegbaren, federbelasteten Ventiltellern 14 und 15, die für die Regelung des Durchlaufes des aus der Kühlmittelleitung 8 und/oder Kurzschlußleitung 9 fließenden Ktihlmittels vorgesehen sind. Die Regelung erfolgt über einen in der Durchflußleitung 2 angeordneten, vom Mischventil 1 abragenden Dehnstoffregler 16, der außerhalb eines Regelraumes 17 in den schon gemischten Kühimittelstrom der Durchflußleitung 2 gelegt ist.The mixing valve 1 shown enlarged in FIG. 2 is in one with several connections for the coolant line 8, short-circuit line 9, Heating line 10 and flow line 2 provided housing 11 arranged, soft is formed by two housing parts lla and lib, which are in sealed form with a sealing ring 12 are connected to one another. The mixing valve 1 consists of two by a piston 13 axially movable, spring-loaded valve plates 14 and 15, for regulating the flow of the from the coolant line 8 and / or Short-circuit line 9 flowing coolant are provided. The regulation takes place Via one arranged in the flow line 2 and protruding from the mixing valve 1 Expansion regulator 16, which is outside of a control room 17 in the already mixed coolant flow the flow line 2 is laid.
Im Gehäuseteil,11a ist über dem Ventilteller 14 ein für die Kurzschlußleitung 9 vorgesehener Ansc1lußstutzen 18 und in etwa 90° zu diesem im Gehäuseteil 11b unterhalb des Ventiltellers 15 ein Anschlußstutzen 19 für die Kühlmittelleitung 8 angeordnet. Parallel zum Anschlußstutzen 18 ist hinter dem Regelraum 17 ein in die Durchflußleitung 2 mündender Anschlußstutzen 20 für die Heizleitung 10 angeschlossen. Die zur Wärmepumpe führende Durchflußleitung 2 ist gegebenenfalls mit einem als Wehr ausgebildeten, in den gemischten Kühlmittel strom ragenden und hinter dem Dehnstoffregler 16 angeordneten Vorsprung 21 versehen.In the housing part 11 a is above the valve disk 14 a for the short-circuit line 9 provided connection piece 18 and at about 90 ° to this in the housing part 11b below of the valve disk 15, a connecting piece 19 for the coolant line 8 is arranged. Parallel to the connection piece 18 is behind the control chamber 17 in the flow line 2 opening connection piece 20 for the heating cable 10 connected. The one for the heat pump leading flow line 2 is optionally designed as a weir, in the mixed coolant stream protruding and arranged behind the expansion regulator 16 Projection 21 is provided.
