Abstract
Description
Anlage zur Patent- und Gebrauchsmusterhilfsanmeldung Kompressor Die Erfindung bezieht sich auf einen Kompressor mit einem zu seiner Antriebswelle exzentrisch gelagerten Rollkolben, der in einer im Querschnitt runden Eohrung eines Kompressorgehäuses zwischen zwei parallelen Seitenwänden umläuft und auf dessen Mantelfläche ein im Gehäuse in einem Schlitz gefhrter,zwischen einem Einlaßkanal und einem Auslaßkanal angeordneter Trennschieber gleitet.Annex to the patent and utility model auxiliary application Compressor Die The invention relates to a compressor with an eccentric to its drive shaft mounted rolling piston, which is in a round cross-section Eohrung of a compressor housing between two parallel side walls and on its outer surface an im Housing guided in a slot, between an inlet channel and an outlet channel arranged slide gate slides.
Ein derartiger Kompressor ist bekannt. Bei diesen bekannten Kompressoren entstehen starke Auflaufgeräusche, wenn der Rollkolben den Trennschieberschlitz iiberrollt. Dabei läuft der Rollkolben auf die Schlitzkante auf, die dem Finlankanal näher liegt, was zu starken Schlaggeräuschen und zu Verschleiß insbesondere der Schlitzkante des Trennschieberschlitzes führt. Je breiter der Trennschieberschlitz ist, desto größer sind die Schlaggeräusche.Such a compressor is known. In these known compressors There are strong noises when the rotary piston opens the slide gate valve slot rolled over. The rolling piston runs onto the edge of the slot, which is the finlank channel closer, which leads to strong impact noises and wear and tear in particular of the Slit edge of the separating slide slot leads. The wider the separator slit is, the greater the impact noises.
Der Erfindung liegt die Aufgabe zugrunde, diesen Nachteil zu vermeiden und einen Kompressor der eingangs genannten Art zu schaffen, der leise läuft und der keinen auffälligen Verschleiß an dem Trennschieberschlitz aufweist.The invention is based on the object of avoiding this disadvantage and to create a compressor of the type mentioned above that runs quietly and which shows no noticeable wear on the slide gate slot.
Diese Aufqabe wird gemäß der Erfindung dadurch qelöst, daß die Gehäusebohrung auf der Einlaßseite des Trennschiebers zwischen der Achse des Einlaßkanals und der dem Einlaßkanal nähergelegenen Kante des Trennschieber-Schlitzes in eine Planfläche iibergeht, die in diese Schlitzkante ausläuft.According to the invention, this task is solved in that the housing bore on the inlet side of the slide valve between the axis of the inlet channel and the the edge of the slide gate slot closer to the inlet channel into a flat surface ii passes, which runs out into this slot edge.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.
Ein Kompressor hat ein Gehäuse 1 mit einer Gehäusebohrung 2. In dem Gehäuse 1 ist eine Antriebswelle 3 gelagert, die auf nicht näher daryestellte Weise einen Rollkolben 4 antreibt. Der Rollkolben 4 wälzt sich mit seiner Mantelfläche 5 an der Wand der Gehäusehohrung 2 ab.A compressor has a housing 1 with a housing bore 2. In the Housing 1 is mounted on a drive shaft 3, which is not shown in detail a rolling piston 4 drives. The rolling piston 4 rolls with its lateral surface 5 on the wall of the housing hole 2.
Auf die Mantelfläche 5 ist ein Trennschieber 6 aufqesetzt, der in einem Gehäuseschlitz 7 geführt und zwischen einem Einlaßkanal 8 und einem Auslaßkanal 9 angeordnet ist. Der Schieber 6 trennt einen Sauaraum 10 von einem Druckraum 11. Die Drehrichtung des Rollkolbens 4 ist durch einen Pfeil f angegeben.A separating slide 6 is placed on the lateral surface 5, which is shown in FIG a housing slot 7 guided and between an inlet channel 8 and an outlet channel 9 is arranged. The slide 6 separates a sowing space 10 from a pressure space 11. The direction of rotation of the rolling piston 4 is indicated by an arrow f.
Auf der Einlaßseite des Trennschiebers 6 geht die sosnst im Querschnitt runde Gehäusebohrung 2 zwischen einer Achse 12 des Finlaßkanals 8 und der dem Einlaßkanal 8 näher gelesenen Kante 13 des Gehäuseschlitzes 7 in eine Planfläche 14 titer, die in diese Schlitzkante 13 ausläuft. F)ie Planfläche 14 erstreckt sich etwa auf 15° des Rollkolben-Umlaufwinkels von 360°.On the inlet side of the slide valve 6, the sosnst goes in cross section round housing bore 2 between an axis 12 of the Finlaßkanals 8 and the inlet channel 8 closer read edge 13 of the housing slot 7 in a flat surface 14 titer, the in this slot edge 13 runs out. F) he plane surface 14 extends approximately to 15 ° of the rotary piston rotation angle of 360 °.
Mit einer derartigen Gestaltung des Rereichs zwischen dem Gehäuseschlitz 7 und dem Einlaßkanal 8 ist erreicht, daß der Rollkolben 2 bei seinem Abwälzen nicht mehr auf die nun zurückgesetzte Schlitzkante 13 aufschlägt.With such a design of the area between the housing slot 7 and the inlet channel 8 is achieved that the rolling piston 2 does not roll during its rolling more hits the now set back slot edge 13.
Dies ist besonders wichtig bei Bauarten mit verhältnismäßig breiten Cehäuseschlitzen.This is particularly important for types with relatively wide Housing slots.
Der Rollkolben 4 läuft nun dort annähernd tanqential gegen die Gehausewand an, wodurch Schlaggeräusche vermieden werden und der Verschleiß vermindert ist.The rolling piston 4 now runs there approximately tanqential against the housing wall on, whereby impact noises are avoided and wear is reduced.
