Abstract

resumo patente de invenção: "dispositivo de controle de admissão da máquina". trata-se de dispositivo de controle de admissão da máquina que inclui um orifício guia de válvula (20) em que um orifício de medição (18c) se abre, uma válvula de desvio (30) para abrir e fechar o orifício de medição (18c), uma peça deslizante (34) ligada à válvula de desvio (30), um eixo rosqueado (35) aparafusado em um orifício rosqueado (42) da peça deslizante (34) e um motor (27) aciona o eixo rosqueado (35), o orifício rosqueado (42) fornecido ao usinar diretamente a peça deslizante (34), a peça deslizante (34) fornecida com um orifício lateral (36) em que uma extremidade interna do orifício rosqueado (42) se abre, a peça deslizante (34) e uma mola espiral (38) dispostas na válvula de desvio (30), a mola espiral (38) impulsionando a peça deslizante (34) em uma direção e o orifício lateral (36) coberto por uma parte enrolada estreitamente (38a) formada na parte da mola espiral (38). isso pode possibilitar que um orifício rosqueado com alta precisão seja formado na peça deslizante e pode impedir que matéria estranha que entrou no interior da válvula de desvio entre no orifício rosqueado sem usar cobertura especial.patent summary of invention: "machine admission control device". it is a machine inlet control device that includes a valve guide hole (20) in which a metering port (18c) opens, a bypass valve (30) for opening and closing the metering port (18c) ), a slide (34) connected to the bypass valve (30), a threaded shaft (35) screwed into a threaded hole (42) of the slide part (34) and a motor (27) drives the threaded shaft (35) , the threaded hole (42) provided when directly machining the slip part (34), the slip part (34) provided with a side hole (36) in which an inner end of the threaded hole (42) opens, the slip part ( 34) and a spiral spring (38) disposed in the diverter valve (30), the spiral spring (38) pushing the sliding piece (34) in one direction and the side hole (36) covered by a tightly wound part (38a) formed in the part of the spiral spring (38). this can enable a high precision threaded hole to be formed in the sliding part and can prevent foreign matter that has entered the interior of the bypass valve from entering the threaded hole without using special covering.
