CIRCUITO PNEUMATICO PARA INFLACAO E DEFLACAO DE PNEUMATICO A BORDO DE VEICULO

摘要

An air circuit for a central tire inflation system having a relief valve (158) in the air circuit to provide the necessary pressure drop for deflation and having make up air from a source (S) bleed into the air circuit via one of two normally closed solenoid actuated valves (164, 174). The make up air is connected via a small orifice (214) when a solenoid (192) associated with a deflate valve (164) or shut off valve (174) is energized.
