Abstract

a presente invenção se refere a um arranjo de vedação de eixo, compreendendo uma primeira vedação (1), uma segunda vedação (2) e uma terceira vedação (3) que são arranjadas em série entre um lado do produto (15) que deve ser vedado e um lado de atmosfera (16), em que a segunda vedação (2) é arranjada entre a primeira vedação (1) e a terceira vedação (3), em que uma primeira pressão (p1) prevalece em um espaço (6, 61) adjacente à segunda vedação (2) no sentido do lado do produto (15), e uma segunda pressão (p2) prevalece em um espaço (7, 71) adjacente à segunda vedação (2) no sentido do lado de atmosfera (16), em que o espaço (7; 71) adjacente ao lado de atmosfera (16) está conectado em uma linha de suprimento de pressão (25) por meio da qual um meio de pressão pode ser suprido para o espaço, e em que a primeira pressão (p1) é igual ou substancialmente igual à segunda pressão (p2), de modo que a segunda vedação (2) pode ser acionada com uma diferença de pressão, entre a primeira pressão (p1) e a segunda pressão (p2), de zero.
