Description
Kompressor mit Leerlaufregelung Die Erfindung bezieht sich sauf einen Kom pressor mit Leerlaufregelungdurch ein vom Druck in einem dem Kompressor zugeordneten Druckluft behälter gesteuertes Ansaugsperrventil.
Bisher wurden !solche Arnsaugsperrventile stets in die vom Ansaugfilter zum Ansaugstutzen des Zylinderkopfes führende .Leitung als besondere Bau teile eingefügt. Der Raum, den sie dort einnehmen, steht dann für andere ,notwendige Aggregate, z. B.
Zwischenkühler oder Nachkühler, nicht mehr .zur Verfügung. Ausserdem behindern so angeordnete An saug sperrventile gegebenenfalls ,auch die Kühlluft- führung.
Erfindungsgemäss werden ,diese Nachteile durch eine raumsparende Anordung ödes Ansaugsperrven- tiles im Zylinderkopf des Kompressors vermieden. Dabei wählt man vorzugswiese eine Anordnung gleichachsig mit dem Zylinder, die besonders (dann vorteilhaft ist,
wenn es sich um einen Kompressor handelt, der mit einem mit dem Zylinder (gleich- achsigen kombinierten Saug- und Druckventil aus gestattet ist. In diesem Falle ist es zweckmässig, ,
das Gehäuse des kombinierten Saug- und Druck- ventiles zur Abstützung .des Sitzes und der Rück- holfeder für das A.nsaugsperrventil heranzuziehen. Die Führungsbüchse ödes Ventilkörpers des Anslawg- ;
sperrventiles befestigt man zweckmässigerweis@e an einem mit dem Zylinderkopf lösbar befestigten, @dek- kelartigen Teil; sie kann aber auch mit einem solchen Teil einstückig sein.
Gegen die von diesem Teil abgewandete freie Stirnfläche der Führungsbüchse kann man .den mit einer entsprechenden Schulter ,ausgestatteten Ventilkörper des Ansaugsperrventiles sich abstützen lassen.
In der Zeichnung ,ist ein Ausführungsbeispiel des Erfindungsgegenstandes im Längsschnitt @darge- stellt. Die Zeichnung zeigt das Kopfende eines Kom- pressorszylinders 1 mit dem Zylinderkopf 2 und ,einem zwischen diesen beiden Teilen angordneten kombinierten Saug- und Druckventil,
idessen zwei- teiliges Gehäuse mit 31 und 32 bezeichnet ist.
Das Ansaugabsperrventil ist in dem mit Odem Ansaugstutzen 21 des Zylinderkopfes in Verbindung stehenden zentralen Raum 22 untergebracht. Es be steht .aus einem Ventilsitz 41 im Zylinderkopf, einem Ventilkörper 42, der in einer Büchse 43 geführt ist und aus einer Ventilfeder 44, die sich einerseits gegen eine Schulter des Ventilkörpers und ander seits gegen Aden Druckhubfä.nger 31 des Kompres- sorventils abstützt,
wobei ihr eine idie beiden Ven- tilteile 31 und 32 zusammenhaltende Verschraubung 33 gleichzeitig als Zentrierung dient.
Die Führungs büchse 43 ist bei dem gezeichneten Beispiel rnit dem Deckel 45 .aus einem Stückgegossen, der eine im. Zylinderkopf vorgesehene Montageöffnung 23 ver schliesst und eine Bohrung 46 zum Anschluss der nicht gezeichneten Leitung für die das Ansiaugab- sperrventil steuernde Drcukluft enthält.
Gegen .die vom Deckel 45 abgewandte freie Stirnfläche der Büchse stützt sich der Ventilkörper in seiner (ge zeichneten Ruhestellung .ab.
Compressor with idle control The invention relates to a compressor with idle control by means of an intake shut-off valve controlled by the pressure in a compressed air tank associated with the compressor.
Up to now, such Arnsaugsperrventile have always been inserted into the line leading from the intake filter to the intake port of the cylinder head as special components. The space they occupy there then stands for other, necessary aggregates, e.g. B.
Intercooler or aftercooler, no longer available. In addition, suction shut-off valves arranged in this way may also hinder the flow of cooling air.
According to the invention, these disadvantages are avoided by a space-saving arrangement of desolate intake blocking valves in the cylinder head of the compressor. It is preferable to choose an arrangement coaxial with the cylinder, which is particularly advantageous
if it is a compressor that is equipped with a suction and pressure valve combined with the cylinder (on the same axis. In this case, it is useful,
Use the housing of the combined suction and pressure valve to support the seat and the return spring for the suction check valve. The guide bushing desolate valve body of the Anslawg-;
shut-off valve is expediently attached to a cover-like part which is releasably attached to the cylinder head; but it can also be in one piece with such a part.
Against the free end face of the guide bush facing away from this part, the valve body of the suction check valve, which is equipped with a corresponding shoulder, can be supported.
In the drawing, an embodiment of the subject of the invention is shown in longitudinal section @. The drawing shows the head end of a compressor cylinder 1 with the cylinder head 2 and a combined suction and pressure valve arranged between these two parts,
The two-part housing is designated by 31 and 32.
The intake shut-off valve is accommodated in the central space 22 communicating with the intake port 21 of the cylinder head. It consists of a valve seat 41 in the cylinder head, a valve body 42 which is guided in a bushing 43 and a valve spring 44 which is supported on the one hand against a shoulder of the valve body and on the other hand against the pressure stroke catcher 31 of the compressor valve ,
A screw connection 33 holding the two valve parts 31 and 32 together serves at the same time as a centering device.
In the example shown, the guide bushing 43 is cast in one piece with the cover 45, the one in the. The assembly opening 23 provided for the cylinder head closes and contains a bore 46 for connecting the line, not shown, for the pressure air which controls the intake shut-off valve.
Against the free end face of the sleeve facing away from the cover 45, the valve body is supported in its rest position.
