ABSTRACT:
In an electromagnetic fluid operating apparatus such as an air compressor in which a piston with an armature axially reciprocates along a path substantially at a right angle to the magnetic flux generated by a stator core due to alternate operation by electromagnetic attraction and mechanical repulsion, exact collimations are automatically established between the armature and the stator core and between the piston and a cylinder for the piston when they are assembled together, thereby minimizing biased frictional abrasion of coacting sliding surfaces. Provision of an internal air reservoir at the air outlet terminal effectively reduces pulsation of air supplied by the apparatus.
