Description

Preßlnffniaschfne. Bei den bisher bekannten Preßluftarbeitsmaschinen mit umlaufendem Kolben wird die Auspuffluft ohne besondere Vorkehrungen, meist sogar einseitig, durch das Gehäuse ins Freie geführt.Press office. In the previously known compressed air machines with a rotating piston, the exhaust air is released without any special precautions, in most cases even on one side, led through the housing to the outside.

Bei diesen Ausführungen tritt ein lästiges Auspuffgeräusch auf.With these versions there is an annoying exhaust noise.

Gemäß der Erfindung wird dieser Nachteil behoben, indem durch Anordnung von Ringrippen und dadurch Schaffung von Kammern im Auspuffraum die Auspuffluft gezwungen ist, in mehreren Stufen zu expandieren, wodurch der Druckunterschied zwischen Auspuffluft irn, Gehäuse und Außenluft verringert und infolgedessen das Auspuffgeräusch gedämpft wird.According to the invention, this disadvantage is overcome by, through arrangement of annular ribs and thereby creating chambers in the exhaust chamber the exhaust air is forced to expand in several stages, reducing the pressure difference between Exhaust air in the inside, housing and outside air is reduced and consequently the exhaust noise is dampened.

Auf der Zeichnung ist der Erfindungsgegenstand beispielsweise und schematisch im Längsschnitt veranschaulicht.In the drawing, the subject matter of the invention is, for example, and illustrated schematically in longitudinal section.

In einem Gehäuse a ist die Welle b mit dem umlaufenden Kolben c vorgesehen, wobei d und e die Arbeitsräume darstellen. Innerhalb des Gehäuses a sind Ringrippen f angeordnet, so daß voneinander getrennte Räume g und lt entstehen und ein gemeinschaftlicher Raum i gebildet wird.The shaft b with the rotating piston c is provided in a housing a, with d and e representing the working spaces. Annular ribs f are arranged within the housing a, so that separate spaces g and lt are created and a common space i is formed.

Dieser Raum i steht durch eine Öffnung k mit einem .das Gehäuse umfassenden Ringkanal L in Verbindung. Der Öffnung k gegenüberliegend ist in dem Ringkanal d eine Auspufföffnung m vorgesehen.This space i stands through an opening k with a .das housing Ring channel L in connection. Opposite the opening k is in the annular channel d an exhaust port m is provided.

Während bisher die Auspuffluft aus den Arbeitsräumen d und e gemeinsam an einer Seite des Gehäuses a entwich, ist durch die Anordnung der Ringrippen f die Auspuffluft gezwungen, von den Arbeitsräumen d und e ihren Weg zuerst zu den getrennten .Räumen g und h zu nehmen, um dann nach Expansion in den gemeinsamen Raum i zu strömen, von wo sie durch die Öffnung k in den Ringkanal L gelangt, dort weiter expandiert und durch die Auspufföffnung m entweicht. Zweckmäßig sind im Ringkanal l die Öffnungen k und na versetzt zueinander angeordnet.While previously the exhaust air escaped from the working spaces d and e together on one side of the housing a, the arrangement of the annular ribs f forced the exhaust air to first make its way from the working spaces d and e to the separate .rooms g and h, in order to then flow after expansion into the common space i, from where it passes through the opening k into the annular channel L , where it expands further and escapes through the exhaust opening m. The openings k and na are expediently arranged offset from one another in the annular channel l.

Claims (1)

PATENTANSPRUCH: PreBluftarbeitsmaschine mit umlaufendem Kolben und als Auspuffraum benutztem Maschinengehäuse, dadurch gekennzeichnet, daB der Auspuffraum durch winklig zur Laufachse angeordnete Ringrippen zur Bildung von Kammern unterteilt und von einem RingauBenkanal umgeben ist, dessen Ein- und Austrittsöffnungen versetzt zueinander angeordnet sind, zu dem Zweck, sowohl das Auspuffgeräusch zu dämpfen als auch das Eindringen von Fremdkörpern in die Arbeitsräume wirksam zu verhindern. PATENT CLAIM: Pre-air working machine with rotating piston and machine housing used as an exhaust chamber, characterized in that the exhaust chamber is subdivided by annular ribs arranged at an angle to the barrel axis to form chambers and is surrounded by an outer annular duct, the inlet and outlet openings of which are offset from one another, for the purpose of both to dampen the exhaust noise and to effectively prevent the ingress of foreign bodies into the work rooms.
