The invention relates to a piston arrangement for a dual-stage piston
compressor, comprising a cranksbaft and several cylinders which house the
operating piston. Said arrangement allows two or more low-pressure stages
and at least one high-pressure stage to be formed. The invention is
characterized in that the two or more low-pressure cylinders are arranged
in relation to the high-pressure stage in such a way that said two or more
low-pressure cylinders are in phase or are offset by less than
.+-.15.degree. and compress in a position which is offset by
180.degree..+-.20, in relation to one or more high-pressure cylinders.
