  • Tires
    Patent number: 3967670
    Abstract: A tire has a succession of peripherally arranged compartments. The compartments are interconnected by separate passages via one-way check valves for inflating the compartments through one passage and deflating them through another. The passages are both connected to a main valve which enables the passages and thereby the compartments to intercommunicate at least during inflation or deflation but separates the passages and thereby the compartments otherwise.
