compresseur non volumétrique

OBS: compresseur non volumétrique : terme uniformisé par le Comité du projet de lexiques (Nouveau-Brunswick).

CONT: Compressors ... may be broadly classified as positive-displacement or nonpositive-displacement machines according to whether or not there is incorporated in the compressor a mechanism functioning in the manner of a check valve to separate the high-pressure discharge from the low-pressure suction. Nonpositive-displacement compressors contain no parts having this function.
OBS: non-positive displacement compressor: term officially approved by the Lexicon Project Committee (New Brunswick).
