Abstract

Patente de Invenção: "DISPOSITIVO DE CONTROLE DE PRESSãO DE óLEO DE TRANSMISSãO CONTINUAMENTE VARIáVEL". Em uma transmissão continuamente variável do tipo correia, as aberturas 55a, 56a dos orifícios de dreno de uma válvula de controle de pressão de óleo empregada para o controle de dispositivos hidráulicos são dispostas fora da região circunferencial W~ B~ da faixa de movimento em que a correia pode ser movida na direção axial da polia quando a largura do sulco de polia é mudada durante a operação de mudança de engrenagem ou fora da região circunferencial W~ p~ da região em que a face do sulco V da polia pode ser disposta quando a largura do sulco de polia é mudada durante a operação da mudança de engrenagem.
