Abstract

"COMPRESSOR DO TIPO HERMéTICO". A presente invenção refere-se a uma câmara de ressonância (128) que é isolada do interior do recipiente hermético devido a uma parte de vedação tendo um flange (118) disposto no silencioso de sucção (110) e ranhura (129) formada no cabeçote de cilindro (123), e a pulsação da pressão de sucção dificilmente vaza para o interior do recipiente hermético, desse modo habilitando a redução de ruído."HERMETIC TYPE COMPRESSOR". The present invention relates to a resonance chamber (128) which is isolated from the interior of the airtight container due to a sealing portion having a flange (118) disposed in the suction muffler (110) and groove (129) formed in the headstock. (123), and the suction pressure pulsation hardly leaks into the airtight container, thereby enabling noise reduction.
