Dual-piston compressor unit for pneumatic spring system of vehicle, has motor with drive shaft whose axis is arranged eccentrically to central axis of two cylinders in opposing state

摘要

The dual-piston compressor unit has motor with a drive shaft (1) having an eccentric portion (2) that cooperates with a link guide (3) in the dual-piston (4), so that the dual-piston performs compression process alternately in the two cylinders (7,8). A compressor is formed by the piston portion (5) and the cylinder (7). The axis of the drive shaft is arranged eccentrically to the central axis of the two cylinders in opposing state.
