Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die auf beiliegender Zeichnung dargestellte Vorrichtung hat den Zweck, das Austreten von Gasen an Stopfbuchsen der Kompressoren von Kälteerzeugungsmaschinen zu verhindern. Die Vorrichtung besteht aus einem Doppelkonus mit cylindrischer Bohrung und zwischenliegender Gaskammer. Der Konus α schliefst in dein Stopfbuchsenhals des vorderen Kompressordeckels, der Konus b in einem besonderen, dem Kreuzkopf zugekehrten Stopfbuchsenaufsatz c. Beide Theile α b sind mit Weifsmetall ausgefüttert und in der Längsrichtung geschlitzt, so dafs beim Anziehen der Schrauben dd ihre innere cylindrische Seite sich fest um die Kolbenstange schmiegt. Ein in der Gaskammer e angebrachtes Ventil f steht vermittelst eines Röhrchens mit der Saugeleitung des Kompressors in Verbindung und hat den Zweck, das mit der Kompressorkolbenstange verschleichende Gas in die Saugeleitung des Kompressors zurückzuführen. Der Druck in der Gaskammer e kann somit den Kompressorabsaugedruck niemals übersteigen.The device shown in the accompanying drawing has the purpose of preventing gases from escaping at the stuffing boxes of the compressors of refrigeration machines. The device consists of a double cone with a cylindrical bore and an intermediate gas chamber. The cone α closes in your stuffing box neck of the front compressor cover, the cone b in a special stuffing box attachment c facing the cross head. Both parts α b are lined with white metal and slotted in the longitudinal direction, so that when the screws dd are tightened their inner cylindrical side clings tightly to the piston rod. A valve f mounted in the gas chamber e is connected to the suction line of the compressor by means of a tube and has the purpose of returning the gas that creeps up with the compressor piston rod into the suction line of the compressor. The pressure in the gas chamber e can therefore never exceed the compressor suction pressure.
