Abstract

VáLVULA. A presente invenção refere-se a uma válvula que inclui um elemento de válvula (34), um assento de válvula (31 b), uma mola espiral (40) e uma porção de sustentação de mola (33). A mola espiral (40), provida entre o elemento de válvula (34) e a porção de sustentação de mola (33) pressiona o elemento de válvula (34) na direção do assento de válvula (31b). Uma extremidade de enrolamento superior efetiva P de T2 da mola espiral e uma extremidade de enrolamento inferior efetiva Q1 e T5 da mola espiral são deslocadas entre si em 180 graus em uma vista plana.
