Abstract

"VEDAçãO ENTRE DUAS PARTES MUTUAMENTE MóVEIS DE UMA MáQUINA HIDRáULICA". A presente invenção refere-se a uma junta disposta entre partes mutuamente móveis de uma máquina hidráulica, por exemplo, uma roda e um alojamento. A referida junta, que é quase vedada, é projetada muito simples. A invenção é caracterizada pelo fato de um elemento de vedação ser alojado em dois mancais hidrostáticos.
