Description

Die Erfindung betrifft einen Kompressor mit konzentrisch angeordnetem Saug- und Druckventil, bei welchem -der Druckkörper als Abschluß des Zylinders bzw. Zy linderkopfes dient und der in der Mitte einen Ansaugkanal hat, dessen Wandungen mit den Außenwandungen des Druckkörpers einen Ringraum bilden. Bei dieser durch ihre Einfachheit und Betriebssicherheit ausgezeichneten Konstruktion bestehen die Übelstände, daß zwar die Luft von oben in den Ringraum eintreten kann und daß auch ,die Kühlrippen an der Außenwand eine gewisse Kühlung bewirken, jedoch ist diese Kühlung naturgemäß nur sehr gering, und die Folge ist, .daß die Ansaugluft einer starken Erwärmung ausgesetzt ist und damit Fiillungsverluste nuftTeten desgleichen die bekannten Nachteile, die die heiße komprimierte Luft hat.The invention relates to a compressor with a concentrically arranged Suction and pressure valve, in which -the pressure body as a closure of the cylinder or Zy cylinder head is used and which has an intake duct in the middle, the walls of which form an annular space with the outer walls of the pressure hull. With this through their simplicity and operational reliability are excellent design Evils that although the air can enter the annulus from above and that too , the cooling fins on the outer wall cause a certain cooling, but this is Cooling naturally only very little, and the result is .that the intake air of a is exposed to strong warming and consequently filling losses incurred as well the known disadvantages that hot compressed air has.

Diese Übelstände werden in einfachster Weise erfindungsgemäß dadurch beseitigt, daß dieser Ringraum eine oder mehrere Ein- und Austrittsöffnungen hat, durch die Kühlluft vom Kühlgebläse gedrückt wird, und daß er durch einen lösbaren Deckel od. dgl. abgeschlossen ist.According to the invention, these inconveniences are thereby alleviated in the simplest manner eliminates the fact that this annulus has one or more inlet and outlet openings, is pressed by the cooling air from the cooling fan, and that it is released by a detachable Lid or the like is completed.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung im Schnitt dargestellt.In the drawing, an embodiment of the invention is in section shown.

Bei Kolbenpumpen,.bei welchen die Saug- und Druckventile konzentrisch zueinander angeordnet und miteinander im Ventilkörper i verbunden sind, wird dieser Ventilkörper normalerweise durch den Druckkörper 2 im Zylinderkopf 3 gehalten. Bei der Abwärtsbewegung des Kolbens 6 gelangt durch den Ansaugkanal q. die Luft durch das in der Mitte liegende Saugventil in den Zylinder 5. Beim Komprimieren drückt der Kolben 6 durch das im äußeren Teil des Ventilkörpers i liegende Druckventil die Luft über den Ringraum 14 in dneD.ruckleitung 7, wobei die Wandung des Druckkörpers 2 starkerwärmt wird.With piston pumps, where the suction and pressure valves are concentric are arranged to one another and connected to one another in the valve body i, this becomes The valve body is normally held in the cylinder head 3 by the pressure body 2. at the downward movement of the piston 6 passes through the intake port q. the air through the suction valve in the middle in the cylinder 5. Presses when compressing the piston 6 through the pressure valve located in the outer part of the valve body i the air via the annular space 14 in the pressure line 7, whereby the wall of the pressure hull 2 is very warm.

Nach der Erfindung sind in der. Wand des Druckkörpers 2 ein oder mehrere mit dem Kühlgebläse 13 in Verbindung stehende Öffnungen 9 vorgesehen und gleichzeitig der Druckkörper 2 durch den Deckel io abgeschlossen. Gegenüber den Öffnungen 9 sind im Druckkörper ein oder mehrere Ablaßöffnungen 12 vorgesehen. Der' vom Kühlgebläse 13 kommende Kühlluftstrom durchströmt mithin den Ringraum 8 und tritt bei 12, ins Freie. Um diesen Luftstrom von dem geraden Weg abzulenken, sind auf dem Ansaugkanal q: eine oder mehrere Rippen i i in entsprechender Länge angebracht, die zweckmäßig gleichzeitig als Kühlrippen ausgebildet sind, so daß sie auch für sich einen Kühleffekt haben. Diese Kühlrippen zwingen den Luftstrom, mehr an den Wänden des Druckkörpers 2 entlangzustreichen (s:. Figur), so daß nicht nur der Ansaugkanal; sondern auch der Druckleörper 2 und damit auch der Ventilkörper i wirksam gekühlt werden. Auf diese Weise wird sowohl die durch den, Ansaugkanal q. einströmende Luft als auch die heiße komprimierte Luft im Ringraum 1q. gekühlt, was bisher wirksam nur durch einen Wasserkühlmantel möglich war oder unvollkommen durch INthlrippe ,n 15 am äußeren Umfange des Zylinders 3.According to the invention are in the. Wall of the pressure body 2, one or more openings 9 connected to the cooling fan 13 are provided and, at the same time, the pressure body 2 is closed off by the cover. Opposite the openings 9 , one or more drainage openings 12 are provided in the pressure body. The cooling air flow coming from the cooling fan 13 consequently flows through the annular space 8 and enters the open air at 12. In order to divert this air flow from the straight path, one or more ribs ii of the appropriate length are attached to the intake duct q, which are expediently designed as cooling ribs at the same time, so that they also have a cooling effect on their own. These cooling fins force the air flow to stroke more along the walls of the pressure hull 2 (see figure), so that not only the intake duct; but also the pressure body 2 and thus also the valve body i are effectively cooled. In this way, both the intake port q. incoming air as well as the hot compressed air in the annulus 1q. cooled, which was previously only possible effectively by a water cooling jacket or imperfectly by INthlrippe, n 15 on the outer circumference of the cylinder 3.
