Abstract

"SERVOMOTOR DE AUXìLIO PNEUMáTICO à FREAGEM DE VEìCULO AUTOMOTOR, VEìCULO AUTOMOTOR E MéTODO DE FABRICAçãO DE UM SERVOMOTOR DE AUXìLIO PNEUMáTICO à FREAGEM". Sendo que a presente invenção relaciona-se principalmente a um servomotor pneumático de auxílio à freagem, minimizando o ruído na cabine do veículo e apresentando um espaço ocupado limitado no compartimento do motor. O servomotor (1) segundo a invenção, comporta uma tomada (25) de alimentação em ar, desembocando no compartimento do motor (35). Tal servomotor (1) comporta um casco definindo sua parede externa (25), uma zona (27) deste casco definindo um canal (29) de alimentação em ar, de preferência à pressão atmosférica, a entrada (57) do canal desembocando no compartimento do motor. Vantajosamente, a zona do casco externo delimitado no canal corresponde à zona traseira dirigida para o avental (33) assegurando uma separação entre o compartimento do motor e da cabine (37) . De preferência, a zona traseira corresponde à parede da câmara traseira (7) susceptível de ser preenchida com ar à pressão desejada.
