Patent number: 10495080Abstract: The present invention relates to the technological field of acoustic filters applied to hermetic compressors. Problem to be solved: In hermetic compressors applied in cooling system, the work fluid sucked by the compression mechanism is hotter than the work fluid coming from the evaporator, and it is known that greater the temperature of this fluid, smaller is the efficiency of the compressor. Resolution of the problem: It is revealed a suction acoustic filter and a suction line including this acoustic filter capable of guarantee that the compression mechanism works mainly with the work fluid coming from the evaporator, which is colder than the work fluid accumulated inside the environment defined by the hermetic housing of compressor.Type: GrantFiled: November 26, 2015Date of Patent: December 3, 2019Assignee: Embraco-Industria De Compressores E Solucoes EM Refrigeracao, LTDA.Inventors: Ricardo Dagnoluzzo Brancher, Dietmar Erich Bernhard Lilie, Andre Ricardo Popinhak, Fabian Fagotti

Patent number: 10174756Abstract: The present relation relates to the technological field of compressors. Problem to be solved: The current reciprocating compressors valves arrangements includes valves whose flexion area suffer from direct interference of the body disposed immediately over said valve. Such feature, besides damaging de valve movement, further causes wear phenomena on the flexion areas of the valve, which can result in critical fault of the valve and consequently of the compressor. Resolution of the problem: It is revealed a valve arrange whose end valve capable of moving includes a flexion area previously defined and intentionally misaligned with any contact area of the body immediately disposed over the valve.Type: GrantFiled: November 25, 2015Date of Patent: January 8, 2019Assignee: Whirlpool S.A.Inventors: Tadeu Tonheiro Rodrigues, Fabian Fagotti, Dietmar Erich Bernhard Lilie
