Abstract

The compressor has one or more cylinders (11, 12) and a crank shaft in a crank housing (15). The crankshaft is set vertical and underneath the cylinder a drive assembly (13), such as an electric motor, is coupled to the crankshaft. A ventilator (20) coupled to the drive assembly or crankshaft produces an air current which moves upwards along the drive assembly and along the cylinder. Compressed air flowing out of the or each cylinder is guided in pipes (34, 35) exposed to the cooling air current of the ventilator.

Description

Die Erfindung betrifft einen Kompressor mit einem oder mehreren Zylindern in liegender Anordnung und mit einer Kurbelwelle in einem Kurbelgehäuse.The invention relates to a compressor with one or several cylinders in a horizontal arrangement and with one Crankshaft in a crankcase.

Aus der US 1 791 672 ist ein Kompressor für die Erzeugung von Druckluft mit zwei Zylindern in Boxeranordnung bekannt. Eine in einem Kurbelgehäuse gelagerte gemeinsame Kurbelwelle wird von einem Elektromotor angetrieben. Elektromotor und Zylinder liegen in der selben horizontalen Ebene. Der Elektromotor ist an seiner Unterseite auf einem Fundament gelagert bzw. mit diesem verschraubt. Der Flächenbedarf der Anordnung ist relativ groß. From US 1 791 672 is a compressor for the generation of compressed air with two cylinders in a boxer arrangement known. A common one stored in a crankcase The crankshaft is driven by an electric motor. Electric motor and cylinder are in the same horizontal plane. The electric motor is on his Bottom stored on or with a foundation screwed. The area requirement of the arrangement is relative large.

Aufgabe der vorliegenden Erfindung ist es, einen Kompressor möglichst kompakter Bauweise zu schaffen.The object of the present invention is a To create a compressor as compact as possible.

Der erfindungsgemäße Kompressor ist dadurch gekennzeichnet, daß die Kurbelwelle vertikal gerichtet ist, dass unterhalb des mindestens einen Zylinders ein mit der Kurbelwelle gekoppeltes Antriebsaggregat angeordnet ist, dass ein mit dem Antriebsaggregat oder der Kurbelwelle gekoppelter Lüfter vorgesehen ist, und dass der Lüfter einen Luftstrom erzeugt, der aufwärts am Antriebsaggregat und an dem mindestens einen Zylinder entlangführt.The compressor according to the invention is thereby characterized in that the crankshaft is directed vertically is that below the at least one cylinder with a the crankshaft coupled drive unit arranged is that one with the power pack or the Crankshaft coupled fan is provided, and that the fan creates an airflow that goes up on Drive unit and at least one cylinder leads along.

Im Gegensatz zu dem oben beschriebenen Stand der Technik ist das Antriebsaggregat, vorzugsweise ein Elektromotor, unterhalb der Zylinder angeordnet. Auf diese Weise ergibt sich ein deutlich verringerter Flächenbedarf. Auch kann die Belüftung und Kühlung beider Aggregate durch einen gemeinsamen Luftstrom erfolgen.In contrast to the prior art described above is the drive unit, preferably an electric motor, arranged below the cylinder. This way a significantly reduced space requirement. Can too the ventilation and cooling of both units by one common air flow.

Die erfindungsgemäße vertikale Anordnung - Zylinder und Antriebsaggregat übereinander - weist vorzugsweise zwei Zylinder in Boxeranordnung auf. Möglich sind aber auch Ausführungen mit nur einem Zylinder oder mit mehreren Zylindern in anderer Anordnung, etwa in Stern- oder V-Anordnung. In allen Fällen sind die Zylinder quer zur vertikalen Kurbelwelle bzw. Antriebswelle vorgesehen.The vertical arrangement according to the invention - cylinders and Drive unit one above the other - preferably has two Cylinder in boxer arrangement. But are also possible Versions with only one cylinder or with several Cylinders in a different arrangement, such as a star or V arrangement. In all cases, the cylinders are transverse to vertical crankshaft or drive shaft provided.

Vorteilhafterweise ist das Antriebsaggregat im Sinne eines Direktantriebs mit der Kurbelwelle gekoppelt. Möglich ist aber auch ein indirekter Antrieb über ein Getriebe.The drive unit is advantageously in the sense of a Direct drive coupled to the crankshaft. Is possible but also an indirect drive via a gear.

Unterhalb der Zylinder, und insbesondere unterhalb des Antriebsaggregats ist ein Lüfter zur Erzeugung eines Luftstromes angeordnet. Der Lüfter ist vorzugsweise als Radiallüfter ausgeführt, wobei die axial in einem den Zylindern abgewandten Bereich des Lüfters einströmende Luft in Radialrichtung ausströmt und seitlich am Antriebsaggregat und/oder an den Zylindern emporstreicht. Es wird eine aufwärtsgerichtete Luftströmung für die Kühlluft und Ansaugluft erzeugt. Antriebsaggregat und Zylinder sind mit Kühlrippen versehen. Die aufwärtsströmende Luft streicht hieran vorbei und bewirkt eine effektive Kühlung. Aufgrund der kompakten Bauweise moderner Elektromotoren stehen die Zylinder seitlich über und liegen genau im Kühlluftstrom.Below the cylinder, and especially below the Drive unit is a fan for generating a Airflow arranged. The fan is preferably as Radial fan executed, the axially in one Area of the fan flowing away from the cylinders Air flows out in the radial direction and on the side Drive unit and / or up on the cylinders. There will be an upward flow of air for the Cooling air and intake air are generated. Drive unit and Cylinders are equipped with cooling fins. The upward flowing air sweeps past and causes effective cooling. Because of the compact design modern electric motors project the cylinders laterally and lie exactly in the cooling air flow.

Im Bereich des Eintritts der Luft in den Lüfter ist ein (erster) Ansaugfilter vorgesehen, vorzugsweise eine Filtermatte. Diese liegt nahe einer Eintrittsöffnung eines dem Lüfter vorgeordneten Eintrittsgehäuses.In the area where air enters the fan is a (First) suction filter provided, preferably one Filter mat. This is close to an inlet opening inlet housing upstream of the fan.

Den Zylindern ist ein (zweiter) Luftfilter zugeordnet, insbesondere ein Luftfilter für mehrere Zylinder gemeinsam. Der Luftfilter ist oberhalb der Zylinder vorgesehen, insbesondere mittig. Lufteinlaßöffnungen des Luftfilters liegen im Bereich der zuvor genannten aufwärtsströmenden Luft.A (second) air filter is assigned to the cylinders, in particular an air filter for several cylinders together. The air filter is above the cylinders provided, especially in the middle. Air intake openings of the Air filters are in the range of the aforementioned upward flowing air.

Der Luftfilter weist einen Ansaugregler auf, so daß kurzfristig die Förderleistung für alle angeschlossenen Zylinder unterbrochen und somit der Betrieb des Kompressors einem geringeren Druckluftbedarf angepaßt werden kann.The air filter has a suction regulator, so that short-term funding for all connected Cylinder interrupted and thus the operation of the Compressor adapted to a lower compressed air requirement can be.

Durch geeignete Ansaugluftführung (der zu verdichtenden Luft) kann die Zufuhr warmer Luft in den Luftfilter vermieden werden. Vorteilhafterweise besteht eine Ansaugluftführung von einer Ansaugöffnung unterhalb der Zylinder zu dem oberhalb der Zylinder angeordneten Luftfilter. Die Ansaugluftführung ist ein Rohr mit entsprechendem Querschnitt. Die Ansaugöffnung weist einen ausreichenden Abstand von wärmeabstrahlenden Flächen, insbesondere Kühlrippen auf. Der tatsächliche Abstand ist von den konkreten Temperatur- und Strömungsverhältnissen abhängig.With a suitable intake air duct (the one to be compressed Air) can supply warm air to the air filter be avoided. There is advantageously one Intake air routing from an intake opening below the Cylinder to the one arranged above the cylinders Air filter. The intake air duct is a pipe with corresponding cross section. The suction opening has one sufficient distance from heat-radiating surfaces, especially cooling fins. The actual distance is of the specific temperature and flow conditions dependent.

Der aufwärtsgerichtete Luftstrom wird vorteilhafterweise durch Luftleitorgane an den Zylindern und am Kurbelgehäuse und/oder am Antriebsaggregat entlanggeführt. Dadurch kann eine schnellere Wärmeableitung erzielt werden. The upward airflow is advantageously through air guiding elements on the cylinders and on the crankcase and / or guided along the drive unit. This can faster heat dissipation can be achieved.

Schwingungstechnisch sind die Luftleitorgane von den Zylindern abgekoppelt.In terms of vibration, the air guiding devices are of the Cylinders uncoupled.

Das Kompressoraggregat - Zylinder, Kurbelgehäuse und Antriebsaggregat - ist in einem Gehäuse gelagert. Die Luftleitorgane sind dem Gehäuse zugeordnet, während das Kompressoraggregat im Gehäuse schwingfähig gelagert ist.The compressor unit - cylinder, crankcase and Drive unit - is stored in a housing. The Air control elements are assigned to the housing, while the Compressor unit is mounted so that it can vibrate in the housing.

Die zu verdichtende Luft wird den Zylindern an deren Oberseiten zugeführt und an den Unterseiten als Druckluft entnommen. Entsprechende Druckluftleitungen verlaufen in einer Ebene unterhalb der Zylinder und liegen im aufwärtsgerichteten Luftstrom.The air to be compressed is transferred to the cylinders Upper sides fed and on the lower sides as compressed air taken. Corresponding compressed air lines run in one level below the cylinders and lie in the upward airflow.

Die Zylinder sind durch eine gemeinsame Druckluftleitung miteinander verbunden. Von einem der Zylinder aus setzt sich diese Druckluftleitung fort und wird in der selben horizontalen Ebene um das Kurbelgehäuse herumgeführt, insbesondere um 180° oder mehr. Dabei weist die umlaufende Druckluftleitung einen ausreichenden Abstand vom Kurbelgehäuse auf, so daß die anfallende Wärme der Leitungen durch möglichst kühle aufsteigende Luft abgeführt wird.The cylinders are through a common compressed air line connected with each other. Sits from one of the cylinders this compressed air line continues and is in the same horizontal plane around the crankcase, in particular by 180 ° or more. The circumferential shows Compressed air line a sufficient distance from Crankcase on, so that the heat of the Pipes through the coolest possible rising air is dissipated.

Der nahe den Zylindern angeordnete Luftfilter weist vorteilhafterweise wärmegedämmte Wandungen auf, insbesondere eine dämmende Bodenplatte. Eine Erwärmung der eintretenden Luft durch das Luftfiltergehäuse wird dadurch vermieden.The air filter located near the cylinders has advantageously insulated walls, especially an insulating floor slab. A warming of the air entering through the air filter housing is thereby avoided.

Antriebsaggregat und Zylinder bilden eine schwingungstechnische Einheit. Entsprechend niedrig ist die Resonanzfrequenz. Diese wird durch weitere Maßnahmen zusätzlich herabgesetzt. So ist die Einheit relativ niedrig gelagert. Hierzu sind Tragarme vorgesehen, deren freie Tragarmenden gehäuseseitig an Lagerpunkten in einer Höhe unterhalb eines Übergangs zwischen den Zylindern und dem Antriebsaggregat gelagert sind. Auf seiten der Einheit greifen die Tragarme etwa zwischen dem Kurbelgehäuse und dem Antriebsaggregat an. Die freien Tragarmenden ruhen auf Dämpfungselementen. Diese sind in Höhe des Schwerpunktes der schwingfähigen Einheit auf entsprechenden Tragbalken oder Streben am Gehäuse angeordnet.The drive unit and cylinder form one vibration engineering unit. Is correspondingly low the resonance frequency. This will be through further measures additionally reduced. So unity is relative stored low. Support arms are provided for this purpose free support arm ends on the housing side at bearing points in one Height below a transition between the cylinders and the drive unit are stored. On the part of unity grab the support arms between the crankcase and the drive unit. The free arm ends rest Damping elements. These are at the level of the focus the oscillatable unit on the corresponding support beam or struts arranged on the housing.

Durch die Tragarme ist die Einheit im Gehäuse sternförmig gelagert. Dabei steht das Kurbelgehäuse im Zentrum der Lagerpunkte.The unit is star-shaped in the housing due to the support arms stored. The crankcase is at the center of the Bearing points.

Schließlich sind den Zylindern Zusatzgewichte zugeordnet. vorteilhafterweise - bezogen auf die Drehung der Kurbelwelle - radial außerhalb der Zylinder. Mit Hilfe der Zusatzgewichte kann das Massenträgheitsmoment um den Schwerpunkt der Einheit erhöht und damit insbesondere der Entstehung von Drehschwingungen entgegen gewirkt werden.Finally, additional weights are assigned to the cylinders. advantageously - based on the rotation of the Crankshaft - radially outside the cylinders. With the help of Additional weights can be around the mass moment of inertia Center of gravity of the unit increased and thus in particular the Generation of torsional vibrations can be counteracted.

Weitere Merkmale der Erfindung ergeben sich aus den Ansprüchen. Insgesamt sind alle offenbarten Merkmale einzeln für sich und in Kombination mit anderen erfindungswesentlich.Further features of the invention result from the Claims. Overall, all of the features disclosed individually and in combination with others essential to the invention.

Ein Kolbenkompressor 10 mit zwei Zylindern 11, 12 in Boxeranordnung ist zusammen mit einem elektrischen Antriebsmotor 13 in einem Gehäuse 14 gekapselt angeordnet, siehe Fig. 2 und 3. Der Motor 13 ist unterhalb eines Kurbelgehäuses 15 mit diesem verbunden. Die nicht gezeigte Antriebswelle und die ebenfalls nicht gezeigte Kurbelwelle des Kompressors sind direkt gekoppelt und somit vertikal gerichtet. Das Kurbelgehäuse 15 wird auch als Zylinderkonsole bezeichnet und beherbergt eine ölfrei arbeitende Kolbenanordnung mit zwei Kolben (ebenfalls nicht gezeigt).A piston compressor 10 with two cylinders 11, 12 in Boxer arrangement is together with an electric Drive motor 13 encapsulated in a housing 14, see FIGS. 2 and 3. The motor 13 is below one Crankcase 15 connected to this. The one not shown Drive shaft and the crankshaft, also not shown of the compressor are directly coupled and therefore vertical directed. The crankcase 15 is also called Cylinder console designates and houses an oil-free one Working piston arrangement with two pistons (also Not shown).

Der Antriebsmotor 13 ist hängend gelagert. Hierzu greifen im Bereich des Übergangs zwischen Motor 13 und Kurbelgehäuse 15 radial (sternförmig) gerichtete Tragarme 16 an. Freie Enden 17 der Tragarme ruhen auf Dämpfungselementen 18. Diese können eine Gummiauflage oder dergleichen aufweisen und sind mit Teilen des Gehäuses fest verbunden. Auf diese Weise ist die Einheit aus Zylindern 11, 12 und Motor 13 relativ zum Gehäuse 14 schwingungsfähig. Die freien Enden 17 liegen etwa auf halber Höhe des Antriebsmotors 13. Erzielt wird dadurch eine relativ niedrige Resonanzfrequenz.The drive motor 13 is suspended. Use this in the area of the transition between engine 13 and Crankcase 15 radially (star-shaped) support arms 16 on. Free ends 17 of the support arms rest Damping elements 18. These can be a rubber pad or have the same and are with parts of the housing firmly connected. In this way the unity is over Cylinders 11, 12 and engine 13 relative to housing 14 capable of vibrating. The free ends 17 lie approximately half the height of the drive motor 13. This is achieved a relatively low resonance frequency.

Die Resonanzfrequenz wird außerdem herabgesetzt durch Zusatzgewichte 19. Je ein Gewicht ist einem Zylinder zugeordnet und sitzt vor dessen Stirnseite. Dadurch weisen die Zusatzgewichte 19 den größtmöglichen Abstand vom Schwerpunkt auf und erhöhen das Massenträgheitsmoment um den gemeinsamen Schwerpunkt. Die Verbindung zwischen den Zylindern 11, 12 und den Zusatzgewichten 19 kann beispielsweise durch verlängerte Zylinderstehbolzen oder parallel hierzu angeordnete Bolzen vorgesehen sein.The resonance frequency is also reduced by Additional weights 19. One weight is one cylinder assigned and sits in front of its face. Show by this the additional weights 19 the greatest possible distance from Focus on and increase the moment of inertia by the common focus. The connection between the Cylinders 11, 12 and the additional weights 19 can for example by elongated cylinder studs or bolts arranged parallel thereto may be provided.

Unten an den Antriebsmotor 13 schließt ein Radiallüfter 20 an, der mit der nicht gezeigten Antriebswelle dreht. Die Luftzufuhr für den Radiallüfter 20 erfolgt von unten axial über eine Düse 21. Diese ist dem Gehäuse 14 zugeordnet, während der Radiallüfter 20 mit dem Antriebsmotor 13 verbunden ist. Entsprechend sind Düse 21 und Radiallüfter 20 schwingungstechnisch voneinander getrennt. A radial fan 20 closes at the bottom of the drive motor 13 on, which rotates with the drive shaft, not shown. The Air supply for the radial fan 20 takes place axially from below via a nozzle 21. This is assigned to the housing 14, during the radial fan 20 with the drive motor 13 connected is. The nozzle 21 and radial fan are corresponding 20 separated from each other in terms of vibration.

Die aus dem Radiallüfter 20 radial austretende Luft wird durch eine im Gehäuse angeordnete Luftleitvorrichtung, insbesondere untere Luftleitbleche 22 aufwärtsgeführt und kühlt den Antriebsmotor 13, die Zylinder 11, 12, das Kurbelgehäuse 15 und weitere wärmebeaufschlagte Teile. Die erwärmte Luft tritt schließlich in einem oberen Bereich aus dem Gehäuse 14 aus, siehe Luftaustritt 23 in Fig. 2 und 3.The air emerging radially from the radial fan 20 becomes by an air guiding device arranged in the housing, in particular lower air baffles 22 and up cools the drive motor 13, the cylinders 11, 12, the Crankcase 15 and other parts subject to heat. The heated air eventually occurs in an upper area out of the housing 14, see air outlet 23 in FIG. 2 and 3.

Ein Teil der aufwärtsgeführten Luft wird als Ansaugluft einem Luftfilter 24 zugeführt. Dieser ist als flaches rechteckiges Gehäuse ausgebildet und oben auf dem Kurbelgehäuse 15 angeordnet. Fig. 1 zeigt eine auseinandergezogene Darstellung des Luftfilters 24. Erkennbar sind eine Bodenplatte 25, ein Rahmen 26 und eine obere Abdeckung 27.Part of the upward air is called intake air an air filter 24 supplied. This is as a flat one rectangular housing and on top of the Crankcase 15 arranged. Fig. 1 shows a exploded view of the air filter 24. A base plate 25, a frame 26 and a can be seen top cover 27.

Die Luft strömt in den Luftfilter über ein abwärts gerichtetes Ansaugrohr 28 an der Bodenplatte 25, siehe insbesondere Fig. 5. Das Ansaugrohr 28 erstreckt sich über mehr als 2/3 der Höhe des Kurbelgehäuses 15. Dadurch gelangt die am Kurbelgehäuse erwärmte Luft nicht in den Luftfilter 24.The air flows downward into the air filter directed intake pipe 28 on the base plate 25, see in particular Fig. 5. The intake pipe 28 extends over more than 2/3 of the height of the crankcase 15. As a result The air heated on the crankcase does not get into the Air filter 24.

Die Bodenplatte 25 und gegebenenfalls weitere Teile des Luftfilters 24 sind wärmedämmend ausgeführt, so daß auch über eine Wärmeleitung keine übermäßige Erwärmung der Ansaugluft stattfinden kann.The bottom plate 25 and possibly other parts of the Air filter 24 are heat insulating, so that too no excessive heating of the via a heat conduction Intake air can take place.

Der Luftfilter 24 ist mit einem für beide Zylinder 11, 12 gemeinsamen Regler 29 versehen, siehe Fig. 5. In Fig. 1 ist lediglich eine Aussparung im Rahmen 26 für den Regler 29 erkennbar. Mit dem Regler 29 ist eine äußerst kurzfristige Regelung der Druckluftabgabe möglich. Geregelt wird die mehr oder weniger starke Freigabe der Ansaugluft auf dem Weg zu den Zylindern 11, 12. Die Ansaugluft wird über entsprechende Ansaugleitungen 31, 32 vom Luftfilter 24 den beiden Zylindern 11, 12 zugeführt, siehe Fig. 2. Der Luftfilter 24 weist zu diesem Zweck entsprechende Anschlußstutzen 33 auf. The air filter 24 has one for both cylinders 11, 12 common controller 29, see Fig. 5. In Fig. 1st is only a recess in the frame 26 for the controller 29 recognizable. With the controller 29 is an extreme short-term regulation of compressed air delivery possible. The more or less strong release of the Intake air on the way to the cylinders 11, 12. Die Intake air is supplied via appropriate intake lines 31, 32 supplied from the air filter 24 to the two cylinders 11, 12, see Fig. 2. The air filter 24 has for this purpose corresponding connection piece 33.

Die erzeugte Druckluft wird in besonderer Weise im Gehäuse 14 geführt. Beide Zylinder sind durch eine unterhalb der selben in horizontaler Ebene verlaufende Druckluftleitung 34 miteinander verbunden, siehe Fig. 1. Die Druckluftleitung 34 beginnt am Zylinder 11 und setzt sich über den Zylinder 12 hinaus fort (genauer unterhalb desselben) und wird einmal um das Kurbelgehäuse herumgeführt, stets in der selben horizontalen Ebene. In Fig. 1 ist der vom Zylinder 12 aus weitergeführte Teil der Druckluftleitung verdeckt und erst mit dem parallel zur Druckluftleitung 34 verlaufenden Teil (Druckluftleitung 35) sichtbar. Dessen Endstück 36 liegt etwa unterhalb des Zylinders 12. Der Austritt der Druckluft aus dem Gehäuse ist nicht gezeigt. Jedenfalls wird die Druckluft nach dem Austritt aus dem Zylinder 12 um etwa 360° um das Kurbelgehäuse herumgeführt in einer horizontalen Ebene und damit im aufwärtsgerichteten Kühlluftstrom liegend. Rechnet man die die Zylinder 11, 12 verbindende Druckluftleitung 34 hinzu, ergeben sich sogar 540°. Aufgrund des Abstands der Druckluftleitungen 34, 35 zum Kurbelgehäuse und zum Motor 13 erfolgt durch letztere keine Erwärmung der Leitungen 34, 35.The compressed air generated is in a special way in the housing 14 out. Both cylinders are through one below the same compressed air line running in a horizontal plane 34 connected to each other, see Fig. 1. Die Compressed air line 34 begins at cylinder 11 and settles beyond cylinder 12 (more precisely below the same) and is once around the crankcase guided around, always in the same horizontal plane. In Fig. 1 is the part continued from the cylinder 12 of the Compressed air line covered and only parallel to the Compressed air line 34 extending part (compressed air line 35) visible. Whose end piece 36 is approximately below the Cylinder 12. The compressed air escapes from the housing is not shown. In any case, the compressed air after Exit from the cylinder 12 by about 360 ° Crankcase guided around in a horizontal plane and thus lying in the upward flow of cooling air. If one calculates the connecting the cylinders 11, 12 Compressed air line 34 added, there are even 540 °. Due to the distance of the compressed air lines 34, 35 to Crankcase and the engine 13 is done by the latter no heating of the lines 34, 35.

Das Gehäuse 14 mit Deckplatte 37, großen Seitenwänden 38, 39 und schmalen Seitenwänden 40, 41 kapselt den Kompressor 10 gegen Schallemissionen und Staub. Eine offene Unterseite ist durch eine große Filtermatte 42 abgedeckt und dient so als Lufteinlaß, Die Filtermatte 42 ist in seitlichen Führungsschienen gehalten. Auf diese Weise wird ein Staubanfall im Gehäuseinneren vermieden. Anstelle der Filtermatte 42 können auch andere Luftfilter zum Einsatz kommen.The housing 14 with cover plate 37, large side walls 38, 39 and narrow side walls 40, 41 encapsulates the compressor 10 against noise emissions and dust. An open one The bottom is covered by a large filter mat 42 and thus serves as an air inlet, the filter mat 42 is in lateral guide rails held. That way a dust accumulation inside the housing avoided. Instead of Filter mat 42 can also use other air filters come.

Der Austritt der Kühlluft erfolgt im Bereich der schmalen Seitenwand 40. Hierzu weist diese nahe der Deckplatte 37 eine Öffnung 43 auf, die sich über die gesamte Breite der Seitenwand 40 erstreckt. Im Gehäuse 14 ist als untere Begrenzung der Öffnung 43 bzw. des Luftaustritts 23 eine horizontale Wandung 44 angeordnet, die sich ausgehend von der Seitenwand 40 über etwa ¾ der Breite der Seitenwand 39 erstreckt und so einen Abluftkanal 45 bildet, der nahe der Seitenwand 41 einen abwärtsgerichteten Durchtritt 46 aufweist.The cooling air exits in the narrow area Side wall 40. For this purpose, this has near the cover plate 37 an opening 43 which extends over the entire width of the Side wall 40 extends. In the housing 14 is the lower Limitation of the opening 43 and the air outlet 23 a horizontal wall 44 arranged, starting from the side wall 40 over about ¾ the width of the side wall 39 extends and thus forms an exhaust air duct 45 which is close to the Sidewall 41 has a downward passage 46 having.

An den großen Seitenwänden 38, 99 sind Luftleitorgane 47, 48, insbesondere Luftleitbleche angeordnet. Diese erstrecken sich über die Breite der großen Seitenwände 38, 39 und sind schrägaufwärts gerichtet, nahe den Zylindern 11, 12 und oberhalb der Druckluftleitungen 34, 35. Dadurch wird die aufwärtsströmende Kühlluft eng an das Kurbelgehäuse 15 geleitet und die Strömungsgeschwindigkeit in diesem Bereich erhöht. Dies bewirkt eine effiziente Kühlung. Das Ansaugrohr 28 erstreckt sich gerade in dem engsten Bereich zwischen Luftleitorgan 47 und Kurbelgehäuse 15.On the large side walls 38, 99 there are air guiding elements 47, 48, in particular air baffles arranged. This extend across the width of the large side walls 38, 39 and are directed obliquely upwards, near the cylinders 11, 12 and above the compressed air lines 34, 35. As a result the upward flowing cooling air becomes close to the Crankcase 15 passed and the flow rate increased in this area. This causes an efficient one Cooling. The intake pipe 28 extends straight into the narrowest area between air guide 47 and Crankcase 15.

Die Düse 21 ist in einen Zwischenboden 49 eingesetzt. Dieser liegt parallel zur Unterseite und bildet so eine Ansaugkammer 50 für die Düse 21. Vorzugsweise ist auf dem Zwischenboden Dämmaterial aufgebracht. Dieses ist in Fig. 2 schraffiert gezeichnet und im übrigen nicht näher dargestellt.The nozzle 21 is inserted into an intermediate floor 49. This is parallel to the bottom and thus forms one Suction chamber 50 for the nozzle 21. Preferably is on the Intermediate floor insulation material applied. This is shown in Fig. 2 hatched and otherwise not closer shown.

Das Gehäuse 14 ist als Rahmenkonstruktion aufgebaut, wie in Fig. 4 ersichtlich. Äußere aufrechte Streben 51 stehen auf Querstreben 52 eines Unterrahmens 53. Oberhalb des Unterrahmens 53 und mit Abstand zu diesem ist der Zwischenboden 49 eingezogen. An einer schmalen Seitenwand 41 ist ein Schaltschrank 54 oberhalb des Zwischenbodens 59 angeordnet.The housing 14 is constructed as a frame structure, such as 4 can be seen. Outer upright struts 51 stand on cross struts 52 of a subframe 53. Above the Subframe 53 and at a distance from this is the Intermediate floor 49 retracted. On a narrow side wall 41 is a control cabinet 54 above the intermediate floor 59 arranged.

Etwa auf halber Höhe der Streben 51 ist ein Mittelrahmen 55 mit entsprechenden Querstreben 56 mit den aufrechten Streben 51 verbunden. Auf den Querstreben 56 sind die Dämpfungselemente 18 gehalten. Demnach ist das Kompressoraggregat am Mittelrahmen 55 schwingfähig gelagert.About halfway up the struts 51 is a middle frame 55 with corresponding cross struts 56 with the upright Struts 51 connected. On the cross struts 56 are the Damping elements 18 held. So that's it Compressor unit on the middle frame 55 oscillates stored.

In Fig. 4 nicht gezeigt sind die Deckplatte 37 und die hierzu parallele Wandung 44. In Fig. 4, the cover plate 37 and the wall 44 parallel thereto.

Der beschriebene Kompressor 10 kann in vielfältiger Weise variiert werden. So können andere Zylinderanordnungen vorgesehen sein, etwa 2x2 Zylinder, je in Boxeranordnung, mit einem Versatz von 90° zueinander, oder eine mehrstufige Anordnung, bei der die aus dem einen Zylinder austretende Druckluft von dem nächsten Zylinder angesaugt und weiter komprimiert wird. Auch können ölgeschmierte Kolben-Zylinder-Anordnungen eingebaut werden. Das Kurbelgehäuse 15 kann dann voll gekapselt sein. In der vorliegenden Ausführungsform weist das Kurbelgehäuse jeweils an den freien Seiten (am oberen Rand) zwischen den Zylindern V-förmige Durchlässe 57 auf, in Fig. 1 ist der hintere Durchlaß verdeckt. Dadurch gelangt Kühlluft in das Kurbelgehäuse hinein. Unterstützt wird dies durch die Gestaltung und Anordnung der Luftleitorgane 47.The compressor 10 described can be used in many different ways can be varied. So other cylinder arrangements be provided, about 2x2 cylinders, each in a boxer arrangement, with an offset of 90 ° to each other, or one multi-stage arrangement in which the one cylinder escaping compressed air is sucked in by the next cylinder and is further compressed. Can also be oil-lubricated Piston-cylinder arrangements can be installed. The Crankcase 15 can then be fully encapsulated. In the present embodiment has the crankcase each on the free sides (at the top) between the Cylinders V-shaped passages 57, in Fig. 1 is the concealed rear passage. This will get cooling air into the Crankcase into it. This is supported by the Design and arrangement of the air guiding elements 47.

Schließlich wird noch auf die Führung der Luft innerhalb des Gehäuses 14 hingewiesen. Zur Darstellung der Luftströmungen sind in den Fig. 2, 3 und 5 Pfeile ohne Ziffern eingezeichnet. Das Gehäuse bzw. die Gehäusewandungen bilden eine äußere Führung für den Kühlluftstrom. Finally, the air is guided inside of the housing 14 pointed out. To represent the Air flows are without arrows in FIGS. 2, 3 and 5 Numbers drawn in. The housing or the Housing walls form an external guide for the Cooling air flow.
