Abstract

MEMBRO TELESCóPICO. A invenção provê um membro telescópico incluindo um cilindro (1) no qual uma haste (2) levando um pistão (3) está montada para deslizar telescopicamente, o membro telescópico incluindo meio de contato interno que é ultrapassável através de uma força predeterminada quando a haste entra em contato dentro do cilindro na direção de encurtamento, o membro sendo caracterizado pelo fato de que o meio de contato interno inclui uma peça de contato (50) se estendendo em um furo aberto dentro da haste (2) e se projetando dela, a peça de contato sendo presa à haste por um pino (51).
