Description

Für Verbrennungsmotoren sind Kühler bekannt,, bei denen zum Vergrößern oder Verkleinern der Kühlfläche zwecks Leistungsve:- änderung oder auch zum Ersetzen beschädigter Teile die einzelnen Kühlelemente auswechselbar angeordnet und Absperrorgane zur Regelung des Durchflusses vorgesehen sind.For internal combustion engines, coolers are known, in which to enlarge or reduce the cooling surface for the purpose of performance: - change or to replace damaged Parts of the individual cooling elements arranged interchangeably and shut-off devices for regulation of the flow are provided.

Das Wesen der Erfindung liegt darin, daß die zum Halten der auswechselbaren Kühlelemente dienenden Anschlußstutzen ein Absperrorgan, beispielsweise ein Hahnküken oder ein Tellerventil, in solcher Verbindung mit einer Klaue -oder einem Bügel besitzen, daß beim Bewegen diese Absperrvorrichtung zugleich durch die Klaue das Kühlefglied festgehakt oder freigegeben wird. Hierdurch ist bei außerordentlicher Einfachheit der Konstruktion die Möglichkeit gegeben, durch einfaches Abschließen des abzuschaltenden Kühler gliedes dieses auch zugleich vom Wasserkasten loszulösen und umgekehrt ein anderes Kühlerglied anzusetzen, indem es einfach an den Stutzen herangehalten und durch öffnen des ,Zuflußhahnes mit Kühlwasser versorgt und zugleich festgehalten wird. Die gleiche Vorrichtung kann am Wässer eintritt wie am Wasseraustritt des Kühlergliedes Verwendung, finden. Besonders vorteilhaft wird die neue Einrichtung, wenn das Äbschlußglied drei Stellungen besitzt, in denen nacheinander der Wasserweg verschlossen und die Klaue offen, dann bei noch verschlossenem Wasserwege die Klaue festhaltend am Kühlergliede im Eingriff und dann endlich bei festhaltender Klaue der Wasserweg geöffnet ist. In diesem Falle, kann ein Kühlerglied abgeschlossen werden, ohne gleichzeitig abgebaut werden z,u müssen.The essence of the invention is that to hold the replaceable cooling elements serving connecting piece a shut-off device, for example a cock plug or a poppet valve, in such connection with have a claw or a bracket that when moving this shut-off device at the same time the cooling member is hooked or released by the claw. This is Given the extraordinary simplicity of the construction, the possibility is given by simple Completing the cooler member to be switched off this also at the same time from the water tank to detach it and vice versa to attach another radiator element by simply attaching it to the The connector held up and supplied with cooling water by opening the feed valve is held at the same time. The same device can enter the water as the water outlet of the radiator element use. The new facility is particularly advantageous, if the terminating member has three positions in which the waterway is successively locked and the claw open, then the claw with the waterway still closed holding on to the radiator member in engagement and then finally the waterway with holding claw is open. In this case, a radiator section can be completed without concurrently be dismantled z, u have to.

Das Absperrorgan baut· sich am besten als einfacher Hahn, der die Klaue derart durch ein Exzenter antreibt, daß sie beim Drehen des Hahnkükens einwärts gezogen wird und das Kühler glied gegen die Dichtung des Anschlußstutzens anpreßt. Die Klaue kann sogar unmittelbar auf einem Exzenter der Hahnkükenachse sitzen. Eine Spielraumkupplung, beispielsweise ein in einem Schlitz der Klaue gleitender Exzenterzapfen des Hahnkükens, der durch eine Feder in seine eine Endlage gebrächt wird, kann weiter dazu dienen, daß im ersten Teile der Hahnkükenbewegung die Klaue über den zu fassenden Teil des Kühlergliedes über gehakt und im zweiten Teile dann nur noch angezogen wird, ohne eine Seitenkraft, auszuüben.The shut-off device is best built as a simple tap that pushes the claw through in this way an eccentric drives that it is pulled inward when the cock plug is turned and the cooler member presses against the seal of the connecting piece. The claw can even sit directly on an eccentric of the cock plug axis. A slack clutch, For example, an eccentric pin of the cock that slides in a slot in the claw, which is brought into its one end position by a spring, can also serve that in the first part of the cock plug movement the claw over the part of the radiator element to be grasped hooked over and then only tightened in the second part without any side force, exercise.

Das Kühlerglied besitzt in günstiger weiterer Ausgestaltung des neuen Anschlusses einen eigenen kleinen Wassersammeikasten, an dem der nach Art der Bienenkorbkühler oder der Röhrenkühler gebaute Kühlerblock angesetzt ist; dieser Wassersammeikasten gibt dabei dem Kühlergliede am Ende die erforderliche Festigkeit, die sein gut abdichtendes Gegenziehen gegen die AnscMußdichtung erlaubt, ohne daß der immerhin etwas rohe Krafteingriff der Festhalteklaue irgendwie für das Kühlerglied nachteilig werden kann.In an advantageous further embodiment of the new connection, the cooler element has a own small water collection box, on which the beehive cooler type or the Tubular cooler-built radiator block is attached; this water collection box gives the At the end of the radiator links the required strength that its well-sealing counter-pulls allowed against the connection seal without the at least somewhat crude force intervention of the Retaining claw can somehow be detrimental to the radiator element.

The cock plug 6 carries a forked handling lever 8 on two square edges 7 of its ends, which allows the cock plug to be turned over by means of a gas pipe or other key to be attached. In addition, the cock plug has two eccentrics 9 on which hook-like claws 10 are placed. Finally, within the eccentric 9, the cock plug carries two more eccentric pins 11 ^: which slide in a matching slot 12 of each claw 10; a spring 13 is in the!

overlap. -

Exactly the same arrangement is symmetrical on the lower part of the radiator member 25 Reversal present.

The handling is as follows. By moving the nozzle 8 and thus the cock plug 6 from the position shown into the position indicated by dash-dotted lines, the claw 10 is first displaced longitudinally by the eccentric 9, by the pin 11 in the slot 12 passes through; with further movement, the pin 11, having reached the end of the slot, takes the Claw with up, and the cooler member 25 is free. The passage opening of the cock plug 6 is now closed. Exactly the same is to be done at the lower end, and the cooler element can then be kept and, if necessary, replaced by another. The insertion operations are exactly the same in reverse order.

Due to the longer design of the slot 12 and a larger angle of rotation of the cock plug 6, the device can be made so that the locking of the cock plug occurs sooner than the complete release of the cooler member by the claws 10, and the cooler element can then remain attached to the cooler in the locked state.

To create a soft counter-surface on the contact surface between the cooler elements and the water collection box 1 is this at the contact surfaces' with a Felt clothing 27 covered. . .

On the rear wall of the water tank 1 an angle 28 is also guided along on which the hood panel 29 is, in the usual Way finally hangs up.
