Patent number: 9599221Abstract: The present invention refers to a connecting rod/piston arrangement for alternative compressor, comprising using at least an intermediate element capable of associating said connecting rod with the piston, wherein both do not radially contact with one another. A process for assembling said connecting rod/piston arrangement for alternative compressor is also disclosed. The connecting rod/piston arrangement for alternative compressor comprises at least a piston (1), at least an intermediate element (2) and at least a connecting rod (3), wherein said piston (1) comprises at least a non-through axial channel (11); said intermediate element (2) comprises at least a through axial channel (21); and said connecting rod (3) comprises at least a connection end (31). In this regard, the intermediate element (2) is securely housed inside the non-through axial channel (11) of piston (1); and said connection end (31) of connecting rod (3) is securely housed inside the through axial channel (21) of intermediate element (2).Type: GrantFiled: June 21, 2012Date of Patent: March 21, 2017Assignee: Whirlpool S.A.Inventors: Alisson Luiz Roman, Celso Kenzo Takemori, Paulo Rogerio Carrara Couto, Wilfred Roettger

Patent number: 9388694Abstract: 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.Type: GrantFiled: December 8, 2011Date of Patent: July 12, 2016Assignee: Whirlpool S.A.Inventors: Celso Kenzo Takemori, Alisson Luiz Roman, Paulo Rogerio Carrara Couto

Publication number: 20140234137Abstract: 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.Type: ApplicationFiled: July 19, 2012Publication date: August 21, 2014Applicant: WHIRLPOOL S.A.Inventors: Alisson Luiz Roman, Otávio Santini Junior
