Mounting arrangement for a resonant spring in a linear motor compressor

摘要

The compressor of the invention comprises: a block with a cylinder; a movable assembly formed by a piston reciprocating in the cylinder and coupled to an actuating means by a rod; and a resonant spring having a first and a second diametrical end portion which are attached to the movable assembly by a first fixation means (MF1) and, to the block, by a second fixation means (MF2) which is adjustably attached to the block and to said second end portion so as to affix the latter to the block in a position defined along the displacement of the resonant spring in three directions orthogonal to one another and defined by the direction of the axis of the resonant spring, by the diametrical direction of the second end portion and by the diametrical direction orthogonal to said two first directions, and also along the angular displacement of said second end portion around said three directions orthogonal to each other.

1. A mounting arrangement for a resonant spring in a linear motor compressor of the type which comprises, in the interior of a shell: a block defining a cylinder; a movable assembly formed by a piston reciprocating in the cylinder, an actuating means and a rod coupling the piston to the actuating means; and a resonant spring having a first and a second end portion which are disposed according to a diametrical direction and attached, respectively, to the movable assembly, in a coaxial manner, by a first fixation means (MF1) and, to the block, by a second fixation means (MF2), characterized in that the second fixation means (MF2) is affixed to the block and to the second end portion of the resonant spring, in an adjustable relative position defined along the displacement of the resonant spring in relation to the block, in three directions orthogonal to one another and defined by the direction of the axis of the resonant spring (I), by the diametrical direction of said second end portion (II), and by the diametrical direction orthogonal to said two directions (III), and also along the angular displacement of the second end portion of the resonant spring around said three directions orthogonal to one another.
