Abstract

BOMBA VOLUMÉTRICA E ELEMENTO DE ALIMENTAÇÃO DE BORRACHA PARA BOMBA VOLUMÉTRICA. A bomba volumétrica (10) compreende um corpo de bomba (12) que delimita uma câmara (14) de colocação sobre pressão e borracha, e um elemento (16) de alimentação da câmara (14) com borracha. O elemento de alimentação (16) compreende um parafuso sem fim (42) móvel em rotação em torno do eixo principal (X) em relação ao corpo de bomba (12) e um corpo de absorção (50) da pressão da câmara (14) de colocação sob pressão solidário axialmente do parafuso (42). O corpo de absorção (50) é distinto do parafuso (42) e apresenta uma superfície (54) que delimita a câmara (14) de colaboração sob pressão e que é disposta axialmente prependicularmente ao parafuso (42).
