Abstract
"DESENGATE DE FREIO DE MãO COM OPERAçãO POR MEIO DE BOTãO DE CALCAR EFETUADO EM AMBOS OS LADOS". é propiciado um aparelho que permite o desengate automático de um sistema de freio de mão de vagão ferroviário a partir de qualquer dos lados do vagão. O aparelho compreende uma fonte de pressão de fluido que pode ser engatada no vagão. Um cilindro de desengate, que é operado por pressão de fluido, está conectado a um mecanismo de freio de mão que pode ser engatado a um sistema de freio situado no vagão. Um meio de válvulas está conectado entre a fonte de pressão de fluido e o cilindro de desengate. Este meio de válvulas obriga o cilindro de desengate a desengatar o sistema de freio de mão. Um primeiro meio atuador de válvula está situado em um primeiro lado do vagão e está conectado entre o meio de válvulas e a fonte de pressão de fluido. Este primeiro meio atuador de válvula obriga o meio de válvulas a iniciar comunicação de pressão de fluído entre a fonte de pressão de fluido e o cilindro de desengate. Um segundo meio atuador de válvula está situado em um segundo lado oposto do vagão e está conectado entre o meio de válvulas e a fonte de pressão de fluido. Este segundo meio atuador de válvula também obriga o meio de válvulas a iniciar comunicação de pressão de fluido entre a fonte de pressão de fluido e o cilindro de desengate.
