Abstract

"DISPOSITIVO PNEUMáTICO DE FREAGEM E DE AMORTECIMENTO, ESPECIALMENTE PARA PARTES DE MóVEIS QUE PODEM SER MOVIDAS". A presente invenção refere-se a um dispositivo pneumático de freagem e de amortecimento para partes de móveis que possam ser movidas com um cilindro (1), dentro do qual está disposto um êmbolo (2) que pode ser deslocado de maneira linear. Dentro do êmbolo (2), está disposta uma válvula de sobrepressão, através da qual pode escapar ar comprimido da câmara de pressão (12), do cilindro (1). A válvula de sobrepressão é formada por um segundo êmbolo (5), o qual está disposto de maneira deslocável linearmente dentro de um espaço oco (10), aberto no lado frontal, do primeiro êmbolo (2)."PNEUMATIC BRAKE AND DAMPING DEVICE, ESPECIALLY FOR MOBILE PARTS OF MOBILE". The present invention relates to a pneumatic braking and damping device for moving parts that can be moved with a cylinder (1), within which a linearly displaceable piston (2) is arranged. Inside the piston (2) is an overpressure valve through which compressed air can escape from the pressure chamber (12) of the cylinder (1). The overpressure valve is formed by a second piston (5) which is linearly displaceable disposed within a hollow space (10) open on the front side of the first piston (2).
