Patent number: 10711777Abstract: The present invention relates to the technological field of compressors and components and/or devices for compressors. Problem to be solved: The current state of the art includes cooling system of dual evaporation and/or dual suction. On the solutions already existing, the selection of one among the two evaporation/suction lines is done by high complexity constructive mechanisms. Problem resolution: The invention in question aims to simplify the construction of a selection mean of one among two evaporation/suction lines. For so, is revealed a suction acoustic filter for reciprocating compressor which integrates an automatic valve coupled to the inlet way of the suction acoustic filter and a valve of a way is coupled to the inlet way of the suction acoustic filter, being said automatic valve and said valve of a way acting selectively reciprocating, where the valve opening of a way ends up opening the automatic valve.Type: GrantFiled: March 18, 2016Date of Patent: July 14, 2020Assignee: Embraco Industria De Compressores E Solucoes EM Refrigeracao LTDAInventors: Paulo Rogerio Carrara Couto, Flavio Jorge Haddad Kalluf, Dietmar Erich Bernhard Lilie, Evandro Luiz Lange Pereira
