Abstract

The present invention relates to a resonant mechanism for compressors which comprises a tubular body (1) containing at least two slot sets (12) that delimit an intermediate surface (13) which central portion has substantially ellipsoidal conformation (14) on which it is located a hole (15) through which the resonant spring will be affixed (2); a resounding spring (2) housed within the tubular body (1); at least two fastening sets (3) for fastening the resonant spring (2) to the tubular body (1), and leaf flat springs (4) alternately and successively mounted with spacers (not shown) along with the circular side faces (11) of the tubular body (1). The slot sets (12) have a specific configuration to allow rigidity and flexibility suitable for the mechanism operation in situations where the resulting axial force differs from zero.

Claims (11)

1. Resonant mechanism for linear compressors CHARACTERIZED in that it comprises:

a tubular body ( 1 );

a resonant spring ( 2 ) housed within the tubular body ( 1 ); and

the tubular body ( 1 ) comprising at least two slot sets ( 12 ), each of said two slot sets ( 12 ) delimiting a respective axially flexible surface ( 13 ), wherein at each axially flexible surface ( 13 ) is provided a respective fastening point for the resonant spring ( 2 );

wherein said fastening points are opposite to each other.

2. Mechanism according to claim 1 , CHARACTERIZED in that it comprises at least one fastening set ( 3 ) for fastening the resonant spring ( 2 ) to the tubular body ( 1 ).

3. Mechanism according to claim 2 , CHARACTERIZED in that the fastening set ( 3 ) comprises an inner male fastening element ( 31 ) that is provided in an fastening hole ( 21 ) of the resonant spring ( 2 ), and an outer female fastening element ( 35 ) that passes through a fastening hole ( 11 ) of the surface ( 13 ) of the tubular body ( 1 ).

4. Mechanism according to claim 3 , CHARACTERIZED in that the slots ( 12 ) comprise adjacent slots separating from each other around the hole ( 11 ), to form the surface ( 13 ).

5. Mechanism according to claim 3 , CHARACTERIZED in that the slots ( 12 ) comprise mirrored slots forming the surface ( 13 ) and a spring portion ( 14 ).

6. Mechanism according to claim 1 , CHARACTERIZED in that the surface ( 13 ) has a substantially ellipsoidal conformation.

7. Mechanism according to claim 1 , CHARACTERIZED in that it further includes at least one leaf flat spring ( 4 ) provided at each end of the tubular body ( 1 ).
