摘要：The invention relates to an oscillating electrodynamic compressor having anelectromagnetic drive which maintains a radial magnetic field in an annular gap in which acoil is arranged for axial contactless movement. The coil is mounted on a plunger guidedinside a bore of a cylinder member forming the compressor. The plunger and coil unit isheld in position by a pair of vibrating springs so as to provide a resilient support bearingon the one hand on the magnet drive and on the compressor on the other hand. Thesprings overlap the cylinder so that the planes in which the springs bear against theplunger and coil unit intersect the cylinder bore guide for the plunger even during thestroke of the plunger.
