Abstract

"DISPOSITIVO DE BOMBEAMENTO DE ALTA PRESSãO E UNIDADE PARA SUPRIMENTO DE COMBUSTìVEL". Tendo um corpo (28) provido com um nicho cilínddco (29) e um pistão (30) montado de uma maneira axialmente deslizante no nicho (29) de maneira a formar uma câmara vadável de volume de bombeamento (31); a câmara (31) sendo comunicante com um duto intemo (52), vía qual é suprida com um fluído, e com um duto de distribuição (44) ao longo do qual é disposto uma válvula de uma via sem retorno (32) de maneira a permitir que o fluído flua da câmara de bombeamento (31) ao longo deste duto de distribuição (44); o dispositivo de bombeamento (11) favoravelmente compreendo uma eletrovalvula (51) cuja abertura e fechamento é controlada, disposta ao longo do duto de entrada (52) de maneira a habilitar o fluído a fluir de uma câmara de bombeamento (31), e uma unidade de controle (36) adaptado a controlar a abertura da eletrovalvula (51) de maneira a causar uma quantidade controlado de fluído a fluir retomando da câmara (31) ao duto de entrada (52), habilitando a regulagem da quantidade de fluído bombeado, a alta pressão, ao longo do duto de distribuição (44).
