Abstract

"VáLVULA AMORTECIDA DE FREIO DE EMERGêNCIA DE VEìCULO". Uma válvula (10) para controlar um sistema de freio de emergência em uma aeronave. A válvula tem cabeçotes separados (38, 58) para controlar o fluxo de fluido de uma linha de suprimento (16) para os cilindros de freio e dos cilindros de freio para uma linha de retorno de tanque (20). Os cabeçotes atuam entre si. Um orifício de amortecimento (48) restringe fluxo de fluido ao redor de um dos cabeçotes limitando assim a taxa na qual aquele cabeçote abre e fecha. Um atuador (86) aplica uma força de controle gerada externamente aos cabeçotes para ativar e desativar o sistema de freio de emergência.
