Abstract

trata-se de um circuito de controle para controlar a pressão de uma roda de pneu, sendo que a roda de pneu compreende: um aro (r); um tubo interno (s), fixável ao aro (r), que encerra um primeiro volume (a); um pneu (t), fixado ao aro (r), que encerra o tubo interno (s) e um segundo volume (b) externo ao tubo interno (s). sendo que o circuito de controle compreende: uma linha de pressão controlada (c), conectável a um compressor; uma primeira linha (11), conectável à linha de pressão controlada (c) e conectada ao primeiro volume (a) para introduzir ar no interior do primeiro volume (a); uma segunda linha (12), conectável à linha de pressão controlada (c) e conectada ao segundo volume (b) para introdução de ar para o interior do segundo volume (b). o circuito de controle compreende ainda uma primeira válvula de carretel (v1), que é uma válvula de três direções e duas posições, tendo uma primeira posição, na qual a linha de pressão controlada (c) é conectada à primeira linha (11), e uma segunda posição, na qual a linha de pressão controlada (c) é conectada à segunda linha (12). a primeira válvula de carretel (v1) é normalmente mantida na primeira posição e ela é comutável para a segunda posição se a pressão no primeiro volume (a) ultrapassar uma pressão predeterminada.
