1. A piston compressor, comprising at least one piston compressor element (3) that is provided with a housing (8) with a compression chamber (13) in which a piston (10) is arranged to move back and forth in an axial direction (X-X′) between an upper dead point and a lower dead point, the piston being driven by a drive shaft (5) driven by a rotary motor (6),
wherein between the drive shaft (5) and the piston (10), a kinematic transmission (20) is provided as a primary drive of the piston (10),
wherein the piston (10) is provided with a complementary drive (25) in the form of an electromagnetic linear drive,
wherein the kinematic transmission (20) comprises a crank and rod mechanism (21-22), and
wherein the piston compressor (1) is provided with a control (27) for determining a momentary position of a crank (21) of the crank and rod mechanism (21-22) and for activating the electromagnetic linear drive (25) at least during a part of a compression stroke of the piston (10) from the lower dead point to the upper dead point of the piston (10) based on the momentary position of the crank (21).
