Abstract

VáLVULA SEM MOLA PARA COMPRESSOR. A presente invenção refere-se a um sistema de fechamento de válvula particularmente adequado para compressores recíprocos que não emprega molas e preferivelmente impulsiona a válvula na direção fechada pela força gerada de magnetos posicionados para repelir um ao outro e dessa maneira distribui a força para manter a válvula do compressor fechada. Outras aplicações são idealizadas e diferentes técnicas para substituir o componente de mola em tais montagens de válvula são também contempladas.
