Abstract

SISTEMA PARA ATENUAçãO DE PULSAçãO NA DESCARGA DE GáS EM UM COMPRESSOR DE REFRIGERAçãO. O sistema de atenuação é aplicável a um compressor que compreende: um cilindro (2) tendo um extremo fechado por uma placa de válvulas (4) provida de um orifício de descarga (4a) e definindo, com o cilindro (2) , uma câmara de compressão (6), sendo uma tampa de cilindro (5) assentada contra a placa de válvulas (4) e definindo uma câmara de descarga (7) que se comunica com o exterior do compressor por uma tubulação de descarga (8) O sistema de atenuação compreende: pelo menos uma câmara intermediária (10) definida no interior da câmara de descarga (7) , para receber, do orifício de descarga (4a), todo o fluxo de descarga proveniente da câmara de compressão (6); e pelo menos um tubo de interligação (20) montado no interior da câmara de descarga (7) , tendo um primeiro extremo (21) aberto para o interior da câmara intermediária (10) e um segundo extremo (22) aberto para o interior da câmara de descarga (7)GAS DISCHARGE PULSE ATTENTION SYSTEM ON A COOLING COMPRESSOR. The attenuation system is applicable to a compressor comprising: a cylinder (2) having an end closed by a valve plate (4) provided with a discharge port (4a) and defining, with the cylinder (2), a chamber (6), a cylinder cap (5) being seated against the valve plate (4) and defining a discharge chamber (7) which communicates with the outside of the compressor by a discharge pipe (8). The attenuation chamber comprises: at least one intermediate chamber (10) defined within the discharge chamber (7) for receiving from the discharge orifice (4a) all the discharge flow from the compression chamber (6); and at least one interconnecting tube (20) mounted within the discharge chamber (7) having a first end (21) open into the intermediate chamber (10) and a second end (22) open into the interior. discharge chamber (7)
