Abstract
Um einen Kältemittelkompressor, umfassend ein Kompressorgehäuse, mindestens eine in dem Kompressorgehäuse angeordnete Zylinderkammer, einen in der Zylinderkammer oszillierend bewegbaren Kolben, einen der Zylinderkammer vorgeschalteten Saugraum, aus welchem Kältemittel in die Zylinderkammer eintritt, einen der Zylinderkammer nachgeschalteten Druckraum, in welchen in der Zylinderkammer komprimiertes Kältemittel eintritt, und einen dem Druckraum nachfolgend angeordneten Auslaßkanal, derart zu verbessern, daß eine möglichst effektive Dämpfung von Pulsationen möglich ist, wird vorgeschlagen, daß komprimiertes Kältemittel über einen Dämpferkanal von dem Druckraum in den Auslaßkanal strömt, daß eine Einlaßöffnung des Dämpferkanals mit einem Querschnittssprung in den Druckraum mündet und daß eine Auslaßöffnung des Dämpferkanals mit einem Querschnittssprung in den Auslaßkanal mündet. Around a refrigerant compressor, comprising a compressor housing, at least one cylinder chamber arranged in the compressor housing, a piston oscillatingly movable in the cylinder chamber, a suction chamber upstream of the cylinder chamber, from which refrigerant enters the cylinder chamber, and a pressure chamber downstream of the cylinder chamber, in which compressed chamber is compressed Refrigerant enters, and to improve an outlet duct arranged downstream of the pressure chamber in such a way that the most effective damping of pulsations is possible, it is proposed that compressed refrigerant flow from the pressure chamber into the outlet duct via a damper duct such that an inlet opening of the damper duct with a cross-sectional jump opens into the pressure chamber and that an outlet opening of the damper duct opens into the outlet duct with a cross-sectional jump.
