A piston compressor (1) is disclosed, in particular for domestic refrigeration machines, having at least one cylinder (2), in which a piston (3) is arranged to move axially, which piston is connected by way of a bolt (7) to a connecting rod (5), the bolt (7) being secured in the piston (3) by means of a press fit (10). It is desirable for the efficiency in such a piston compressor to be improved. To that end, the press fit (10) comprises a pairing of seating surfaces which is under reduced normal stress circumferentially of the piston (3).
