Kolbenverdichter für eine Kompressionskältemaschine.

<Desc/Clms Page number 2>
mässig, wie veranschaulicht, etwas kürzer gehalten, um den Ventilen die Möglichkeit zu geben, beim Auf-und Niedergehen etwas zu kippen, d. h. die verschiedene Länge der Federn bewirkt sozusagen ein Atmen der Ventilplatten, die Wirkung wird dadurch geräuschloser und die Ventile schleifen sich gut ein.
Dieselben Plattenventile werden auch am Kolben verwendet. Die Kolben 3 sind in üblicher Weise mit Liderungsringen versehen und am oberen Ende durchbohrt, um die Plattenventile anzubringen. Wie vorher beschrieben, sind die Durchgangsöffnungen von einer konzentrischen Nut 9 a umgeben, in welche die Lappen 11 a der Ventilplatten 3 a eingreifen. Die Ventilplatten werden durch Querstege, z. B. Blechstreifen oder auch runde, mit Zapfen versehene und zwecks Durchlass des Kältemittels durchbohrte Deckel 3 b, die an der Kolbendecke befestigt sind, mit geringem Spiel festgehalten, so dass die Ventile atmen können, ohne dass die Randvorsprünge 11 a mit der Nut ausser Eingriff kommen.
Die Abmessungen der Zapfen der Deckel 3 b können der Grösse der Löcher 8 entsprechen.
Beim Arbeiten des Verdichters werden die Plattenventile 10 abwechselnd angehoben, während immer die zugehörigen Kolbenventile geschlossen sind. Das durch die Kolben getretene Kältemittel wird unter Druck in den Sammelraum 7 gepresst.

moderately, as illustrated, kept a little shorter in order to give the valves the possibility of tilting something when moving up and down, i.e. H. The different length of the springs causes the valve plates to breathe, so to speak, the effect is less noisier and the valves grind in well.
The same plate valves are used on the piston. The pistons 3 are provided with eyelid rings in the usual way and are pierced at the upper end in order to attach the plate valves. As previously described, the through openings are surrounded by a concentric groove 9 a, in which the tabs 11 a of the valve plates 3 a engage. The valve plates are through cross webs, for. B. sheet metal strips or round, provided with pegs and pierced for the purpose of passage of the refrigerant cover 3 b, which are attached to the piston top, held with little play so that the valves can breathe without the edge projections 11 a disengaging from the groove come.
The dimensions of the pins of the cover 3 b can correspond to the size of the holes 8.
When the compressor is working, the plate valves 10 are lifted alternately while the associated piston valves are always closed. The refrigerant that has passed through the pistons is forced into the collecting space 7 under pressure.
