Abstract

The invention relates to the charge cycle timing in internal combustion engines. The problem of accommodating control elements and/or valves in the combustion chamber is essentially solved in that only one valve is arranged in the working or combustion chamber, whilst the exhaust and refilling of the gases is performed by this valve, that is outside the heat-affected zone. The possible uses of the invention occur in the internal combustion engine sector and include the internal exhaust gas recirculation in the timing of the charge cycle. The rotary slide valve A shown in the figure assumes the control function without high pressure and thermal stresses; at the same time it does not have to seal hermetically like the one valve H in the combustion chamber. The control function of the rotary slide valve A includes the specific exhaust gas recycling in its structure.

Description

Der Arleitsraum einer Brennkraltmaschine wird durch die Platte P und ein Kegelsitzventil V legrenzt. Die Betätigung der Ventilsteuerung erfolgt durch die Welle W1. Der gaswechsel im Zylinderkopf Z erfolgt durch wechselweises Verlinden der Kanalöffnung E mit dem Kanal K des Ventiles V für Einlaß üler den Diehschielen S, lzw. nach 180° grad Drehung des Drehschielers S, durch Verlinden zum Auslaßkanal A und damit üler den Kanal K zum Ventil V. The Arleitsraum an internal combustion machine is through the plate P and a cone seat valve V is limited. The valve control is actuated by the wave W1. The gas change in the cylinder head Z takes place by alternately connecting the channel opening E with the channel K of the valve V for inlet üler the Diehschielen S, lzw. after turning the squint S by 180 °, by connecting to the outlet channel A and thus over channel K to valve V.

Die Zahnräder R 1 und R 2 versetzen den Drehschieler S in die zum Kollenhul algestimmte Drehung, während das Ventil V stehen lzw sich relativ wenig mitdrehen kann und üler die Steuerkurve U geöffnet , üler die Feder F entsprechend der Kurvergestalt geschlossen wird. Zur Lagerung des Ventiles V dienen an 2 Stellen Buchsen B und das Drucklager L unter dem Teller der Feder F . Der Drehschieler sellst ist durch 2 @älzlager U mit Spielausgleich geführt und durch Dichtring D algedichtet.The gears R 1 and R 2 move the squint S to the Kollenhul as tuned rotation, while the valve V is relatively little can rotate with it and the control cam U is opened, the spring F accordingly the curve shape is closed. There are 2 places to store the valve V Bushings B and the thrust bearing L under the plate of the spring F. The squint sellst is guided by 2 roller bearings U with clearance compensation and sealed by sealing ring D.

Die kegelige Auslildung des Drehschielers S wird in der Technik als " Aspin-Schieler " lezeichnet. Die Trennflächen T auf dem Kegelmantel lildeten lei lisher lekannten Anwendungsleispielen die Dichtflächen der Ventilfunktion. Um dies zu vermeiden wurde die Platte P mit dem , den Brennraum legrenzenden Ventil V entwickelt. Dadurch wurden sowohl die thermischen Dehnungs- alsauch die Dichtprolleme gelöst. The conical training of the squint S is in technology as "Aspin-Schieler" draws. The parting surfaces T on the cone envelope lilden lei Previously known application examples were the sealing surfaces of the valve function. To this To avoid this, the plate P with the valve V limiting the combustion chamber was developed. As a result, both the thermal expansion and sealing prollems were released.
