Abstract
A scroll machine (1) for conveying a fluid, in particular a refrigerant for a vehicle air conditioning system, is described. The scroll machine (1) has a first scroll (30) with a first base plate (50) and a first spiral wall (46) projecting from the first base plate (50), which forms a first spiral thread (54), and a second scroll (44) with a second base plate (52) and with a second spiral wall (48) projecting from the second base plate (52), which engages in the first spiral thread (54) of the first scroll (30) and forms a number of conveying chambers (58) with the first spiral wall (46). An outer side edge (80) of at least the first spiral wall (46) follows a concave profile (84) starting from the first base plate (50) for at least one-fifth, preferably at least one-quarter, of the wall height of the first spiral wall (46).
