Abstract
A resonant assembly for a reciprocating compressor driven by a linear motor. The compressor includes a piston (2), driven by an actuator (3), which reciprocates inside a cylinder (1a) provided with an end closed by a head. The assembly comprises a resonant element, defining by a single piece, a rod portion (11) and a spring portion (12). The spring portion is affixed to a non-resonant structure (1) of the compressor at a plurality of points which are symmetric in relation to the longitudinal axis of the cylinder and lie on a plane orthogonal to the longitudinal axis of the cylinder.
