Abstract

quando uma válvula de alívio de pressão (7) é fechada totalmente à força para controle de aprendizado no momento da partida, a força de acionamento de um atuador elétrico (20) é inicialmente definida como um primeiro nível grande, e quando uma posição predeterminada (l1) imediatamente antes do assentamento é alcançada, a força de acionamento é reduzida para um segundo nível. como resultado, o corpo da válvula (7a) é assentado suavemente. após um tempo predeterminado (tm1) ter decorrido, a força de acionamento é aumentada para um terceiro nível. consequentemente, o atuador elétrico (20) pressiona o corpo da válvula (7a) sobre uma superfície de assentamento (34a), ao mesmo tempo deslocando um membro de mola (37). como resultado, obtém-se uma capacidade de vedação confiável.
