Gegenstand der vorliegenden Erfindung bildet ein Druckluftanlaßventil für Verbrennungskraftmaschinen. The present invention provides a compressed air inlet valve for internal combustion engines.
Die Druckluft anlaßventile bekannter Art haben häufig den Nachteil, daß sie flattern und unruhig und unsicher arbeiten. Diese Nachteile werden durch die vorliegende Erfindung in einfacher Weise beseitigt.The compressed air starting valves of the known type often have the disadvantage that they flutter and work restless and insecure. These disadvantages are addressed by the present invention eliminated in a simple manner.
Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schnitt dargestellt. An exemplary embodiment is shown in the accompanying drawing the invention shown in section.
α ist das Ventil, auf welchem von unten her der im Verbrennungszylinder jeweils herrschende Druck lastet, b ist der Entlastungskolben, welcher dazu dient, den Druck auszugleichen, welcher von der zum Anlassen dienenden Preßluft auf die Ringfläche c ausgeübt wird. Der Entlastungskolben setzt sich nach oben fort und trägt dort den besonderen Steuerkolben d, dessen nach innen gekehrte Fläche unter Atmosphärendruck steht. Um diesen zu sichern, ist, wie die Zeichnung ersehen läßt, die Federbüchse durch eine Öffnung mit der Außenluft in Verbindung gesetzt. Die Steuerung erfolgt dadurch, daß Preßluft durch den Kanal f in den Raum g gelassen wird. Die zum Steuern dienende Preßluft drückt dann auf die ganze Fläche des Kolbens d, welcher so groß ist, daß das Ventil noch mit Sicherheit geöffnet und auch offen gehalten wird, selbst wenn der im Motorzylinder herrschende Druck größer ist als die Pressung der zum Steuern dienenden Luft. Der Abschluß des Ventils wird durch die Feder h herbeigeführt, sobald die Druckluft aus g entlassen wird. α is the valve on which the pressure prevailing in the combustion cylinder is applied from below, b is the relief piston, which serves to compensate for the pressure exerted on the annular surface c by the compressed air used for starting. The relief piston continues upwards and carries the special control piston d there, the inward-facing surface of which is under atmospheric pressure. In order to secure this, as the drawing shows, the spring sleeve is connected to the outside air through an opening. The control takes place in that compressed air is let through the channel f into the room g . The compressed air used for controlling then presses the entire surface of the piston d, which is so large that the valve is still opened with certainty and also kept open, even if the pressure prevailing in the engine cylinder is greater than the pressure of the air used for controlling . The closure of the valve is brought about by the spring h as soon as the compressed air is released from g .
