ARRANGEMENT AND PROCESS FOR MOUNTING A RESONANT SPRING IN A LINEAR MOTOR COMPRESSOR AND A LINEAR MOTOR COMPRESSOR

摘要

A compressor comprising: a cylinder crankcase (10) defining a compression chamber (13) housing a reciprocating piston (22); an actuating means (40) coupled to the piston (22); and a resonant spring means (50) having a first and a second diametrical end segment (50a, 50b) respectively affixed to the actuating means (40) by a first securing means (MF1) and to the cylinder crankcase (10) by a second securing means (MF2), the latter comprising: a base vise jaw (60, 60′) affixed to the second diametrical end segment (50b); a top vise jaw (70, 70′) mounted between opposite portions of the cylinder crankcase (10) and seated, pressed and locked against the base vise jaw (60, 60′), in a condition in which the axes of the end diametrical segments (50a, 50b) intercept the axis of the compression chamber (13) and in which the piston (22) has a predetermined axial position in the compression chamber (13).

1. An arrangement for mounting a resonant spring in a linear motor compressor of the type comprising: a cylinder crankcase defining a cylindrical region inside which is formed a compression chamber a piston reciprocating in the compression chamber, an actuating means coupled to the piston; and a resonant spring means having a first diametrical end segment, affixed to the actuating means by a first securing means and a second diametrical end segment, affixed to the cylinder crankcase by a second securing means, characterized in that the second securing means comprises:
a base vise jaw rigidly affixed to the second diametrical end segment of the resonant spring means in a predetermined position; a top vise jaw mounted, by a first tightening means, between two opposite portions of the cylinder crankcase and seated and compressed, by at least one second tightening means and in an axially and radially adjustable manner, in relation to the shaft of the resonant spring means, against the base vise jaw, locking the latter to the top vise jaw, in a condition in which the axes of the end diametrical segments of the resonant spring means intercept the axis of the cylindrical region of the cylinder crankcase and in which the piston presents a predetermined axial position inside said cylindrical region.
