In den Figuren der Zeichnung sind gleiche oder ähnliche Teile mit denselben Bezugszeichen versehen. Es handelt sich hierbei lediglich um eine Ausführungsbeispiel, welches keinen auf die Erfindung beschränkenden Charakter hat.In the figures of the drawing, the same or similar parts are given the same reference numerals. This is merely an embodiment which has no character limiting the invention.

Aus den Figuren 1 und 2 ist eine insgesamt mit 1 bezeichnete Schraubenverdichteranlage nach der Erfindung zu ersehen, welche teilweise die funktionswesentlichen Teile einer solchen Schraubenverdichteranlage, allerdings ohne Vollständigkeit, zeigen. Aus den Figuren der Zeichnung ist aber das Bauprinzip der Erfindung in Modulbauweise zu erkennen. Die dort gezeigte Schraubenverdichteranlage 1 umfasst ein Basisgehäuse 2 als Basismodul, dessen Innenraum mit einem Deckel 3 verschließbar ist. In diesem Basisgehäuse 2 als Basismodul sind in zusammengefasster Anordnung ein Schraubenverdichterblock, ein Ölabscheidebehälter, ein Ölversorgungskanal für den Öltemperaturregler und der Luftansaugkanal integriert. Ein Ansaugventil 5 mit einem darauf montierten Ansaugfilter 6 ist schematisch in Figur 1 in auseinander gezogener Darstellung gezeigt. Das Ansaugventil 5 mit dem Ansaugfilter 6 werden entsprechend Figur 2 auf das Basisgehäuseteil 2 montiert. Ferner ist aus Figur 1 ein insgesamt mit 10 bezeichneter Multifunktionsblock zu ersehen. In diesem Multifunktionsblock 10 sind ein Feinabscheider, eine Ölrückführung, ein Mindestdruckhalteventil mit einem Reinluftaustritt, ein Öltemperaturregler, ein Ölfilter und ggfs. Anschlüsse für einen Kühler zusammengefasst. Dieser Multifunktionsblock 10 kann an die jeweils zu realisierenden Erfordernisse und Anforderungen hinsichtlich der Filtereinrichtung und dgl. angepasst werden. Mit dem Multifunktionsblock 10 ist eine schematisch angedeutete Steuereinheit 11 wirkverbunden.From the FIGS. 1 and 2 is a generally designated 1 screw compressor plant according to the invention, which partially show the functionally essential parts of such a screw compressor system, but without completeness. From the figures of the drawing but the construction principle of the invention can be seen in modular design. The screw compressor system 1 shown there comprises a base housing 2 as a base module, the interior of which is closable with a cover 3. In this basic housing 2 as the base module, a screw compressor block, an oil separation tank, an oil supply channel for the oil temperature regulator and the air intake duct are integrated in a combined arrangement. An intake valve 5 with a suction filter 6 mounted thereon is shown schematically in FIG FIG. 1 shown in an exploded view. The suction valve 5 with the suction filter 6 are accordingly FIG. 2 mounted on the base housing part 2. Furthermore, it is off FIG. 1 to see a total of 10 designated multifunction block. In this multi-function block 10 a fine separator, an oil return, a minimum pressure holding valve with a clean air outlet, an oil temperature regulator, an oil filter and, if necessary, connections for a cooler are summarized. This multifunctional block 10 can be adapted to the respective requirements and requirements to be realized with respect to the filter device and the like. With the multi-function block 10, a schematically indicated control unit 11 is operatively connected.

Aus der Zusammenbaudarstellung in der Figur 1 ist zu ersehen, dass diese Schraubenverdichteranlage 1 kompakt ausgelegt ist und sich hinsichtlich der Erfordernisse in flexibler Weise anpassen lässt.From the assembly diagram in the FIG. 1 It can be seen that this screw compressor unit 1 is compact and can be flexibly adapted to the requirements.

Aus den Figuren 3 und 4 sind ergänzend noch Einzelheiten hinsichtlich einer Antriebsseite 15 und einer Bedienungsseite 16 zu ersehen.From the Figures 3 and 4 are additional details with respect to a drive side 15 and a control page 16 can be seen.

So ist der Multifunktionsblock 10 auf der Bedienungsseite 16 der Schraubenverdichteranlage 1 angeordnet und daher für notwendige Wartungsarbeiten leicht zugänglich, ohne dass weitere Funktionsteile der Schraubenverdichteranlage 1 demontiert werden müssen. Die Antriebsseite 15 liegt etwa rechtwinklig zu der Bedienungsseite 16, an welcher der Multifunktionsblock 10 angeordnet und angebracht ist. Somit ist ein ungehinderter Zugang zur Antriebsseite 15 der Schraubenverdichteranlage 1 gegeben.Thus, the multifunction block 10 is arranged on the operating side 16 of the screw compressor system 1 and therefore easily accessible for necessary maintenance, without further functional parts of the screw compressor system 1 must be dismantled. The drive side 15 is approximately at right angles to the operating side 16, on which the multifunction block 10 is arranged and mounted. Thus, an unobstructed access to the drive side 15 of the screw compressor system 1 is given.

Selbstverständlich ist die Erfindung nicht auf die vorangehend beschriebenen Auslegungseinzelheiten beschränkt. Sie ist in den beigefügten Ansprüche definiert, so dass zahlreiche Abänderungen und Modifikationen möglich sind, ohne der Schutzumfang der Ansprüche zu verlassen.Of course, the invention is not limited to the details of the design described above.
