Abstract: The present invention refers to a linear compressor based on resonant oscillating mechanism, which comprises an oscillating arrangement essentially formed by at least one linear motor (2) defined by a movable portion (22) and a fixed portion (21), at least a resonance spring (3), at least one piston (4) and at least one balancing body (5), wherein the movable portion (22) of the linear motor (2) is cooperatively associated with the piston (4), defining a piston-motor assembly. The piston-motor assembly is operatively associated to the end (31) of the resonant spring (3) and at least one balancing body (5) is functionally associated with the end (32) of the resonant spring (3). This construction allows the attenuation of the vibration that the resonant oscillating mechanism applies to the compressor housing through the cancellation of the forces generated by the motor and the forces generated by the compression of gas in the cylinder.

Abstract: The invention refers to a resonator arrangement for the cabinet of a refrigeration appliance, said cabinet defining a housing and carrying, in the latter, a compressor presenting a hermetic casing and a defrost water evaporating tray comprising: a bottom wall, to be seated onto an upper portion of the casing of the compressor; and a peripheral wall superiorly projecting from the bottom wall, at least one of the peripheral wall and bottom wall of the evaporating tray carrying a noise absorbing means turned to a noise generation region in said housing and being dimensioned to define a certain reactive impedance and a certain dissipative impedance in the medium of the housing for a determined frequency band.
