Abstract
A suction gas conduit (1) for a refrigeration compressor has a curved section (4) of the gas path (2), which connects an inlet section (3) of the gas path to an outlet section (5). A widening (11) in the form of a step (12) is located on the inner side of the curve of the gas path. The curved section (4) especially abuts, at the outlet end, a valve plate (7) of the compressor, which valve plate (7) has a suction gas opening (6). The outer side of the curve of the gas path (2) is unimpeded. The step height (H) is from 0.3 to 1.0 times, and the step length (L) from 0.2 to 1.0 times, the hydraulic diameter (d) of the outlet section (5). As a result thereof, the unavoidable recirculation flow is located in a position where its undesirable effect is limited.
