Abstract
A double-piston compressor of a compressed air supply device includes a first pressure stage and a second pressure stage, each having a cylinder with a piston guided therein in an axially movable manner. The piston of the cylinder of the first pressure stage and the cylinder of the second pressure stage are rigidly connected to one another via a piston rod and are in driving connection with the drive shaft via a slotted guide. The slotted guide comprises a recess which is formed in the piston rod, provided with a slotted guide track and oriented perpendicularly to an axis of rotation of the drive shaft with its cross-sectional plane. The slotted guide comprises a drive roller which is engaged with the recess and fastened to the drive shaft in an axially parallel, eccentric, and also rotatable manner with respect to the axis of rotation of the drive shaft.
