German term or phrase: Kreiskolbenverdichter
again: automotive air conditioning systems
"Verwendet werden vorzugsweise Hubkolbenverdichter mit Taumelscheibe, deren Kolben axial angeordnet sind, wodurch sich die Trgheitskrfte infolge der Kolbenanordnung aufheben und die Momentenungleichfrmigkeit sehr gering wird.
Inzwischen wurden aber auch verschiedene Rotationskolbenmodelle, wie z.B. Flgelzellen-, Spiral-, Rollkolben- und Kreiskolbenverdichter fr den Betrieb im Kfz entwickelt und eingesetzt."

According to Ernst, Rollkolbenverdichter is a "rotating piston compressor," and Kreiskolbenverdichter is a "rotary piston or rotary displacement compressor." Help! Are these just slight variations on the same development type, or is there a difference?
Many thanks in advance.

rotary displacement compressor
Explanation:
I'd stick with that one, here's why:
Kreiskolbenverdichter seems to refer directly to the part of the air conditioning that compresses the air for cooling while rotary piston refers more to the car engine's piston. All these are, as you concluded, variations on a theme, with the theme being the Wankel engine engineered by the ingenious Felix Wankel (the resource at the URL is fabulous).

Cheerio,
Dierk

Spanish Term: compresor alternativo
Definition compresor de desplazamiento positivo que consta de uno o varios cilindros en serie,según sea de una o varias etapas,en los que el gas es aspirado,comprimido y descargado mediante émbolos

Collection Pumps (=PUM83)

Waelzkolben/pumpe;
Roots/pumpe
English Term: rotary piston lobe type pump;
lobular pump
Spanish Term: bomba lobular

I would say it is rotary screw compressor.

See:

Operation
A rotary screw uses two rotors to push air through the compressor, which creates pressure. Compression is accomplished by the main and secondary rotors synchronously meshing in a one-piece, dual-bore housing. The main rotor has helical lobes and the secondary rotor has helical grooves (Fig. 2). The air inlet port is located on top of the housing near the drive shaft end. The discharge port is near the bottom at the opposite end of the housing. Figure 2 is inverted to show both ports.

Good luck.

rotary piston compressor, rotary compressor , rotary supercharger


Explanation:
Wyhlidal: Kreiskolbenkompressor: rotary piston compressor, rotary compressor (aufgeladener Motor - supercharged engine) rotary supercharger (Wyhlidal, Kraftfahrzeugtechnisches W. ISBN 3 923195 01 X).

THe second paragraph in your query text leaves little doubt that the terms you are pondering (Rollkolben - vs. Kreiskolben) are variants of the same basic rotary principle. An animated graph in the following URL suggest what the Rollkolben version might look like. A Kreiskolben probably differs in the form of, particularly, the rotating member.
