ABSTRACT:
A reciprocating compressor with a linear motor having an actuating means operatively coupling a reciprocating piston to the motor; and a resonant spring means mounted under constant compression to the actuating means by the mutual seating of a pair of supporting surface portions, at least one of the latter being operatively associated with one of the spring means and the actuating means, against a respective pair of convex surface portions, each of the latter being operatively associated with the other of said parts, the convex surface portions being symmetrical and opposite in relation to the axis of cylinder, the supporting surface portions and the convex surface portions being mutually seated and operatively associated with the respective parts of the spring means and the actuating means, in order to transmit, by the mutually seated surface portions, the opposite axial forces with such intensity as to minimize the moments on the piston.
