Abstract

DISPOSITIVO EXTRATOR Um dispositivo para extração da bucha de pino (4), do casquilho (5) e do calço (6) da região de formato cónico do pino de cilindro (2) de um cilindro (1), onde um anel de encosto de pressão (8) se acha disposto sobre um conjunto de pinos de cilindro (3) do cilindro (1), que se apóia na face frontal da bucha de pino (4), deve ser de tal modo melhorado, que ele seja construído de maneira muito curta, e onde o movimento do dispositivo extrator já seja alcançado com pequenas pressões de um agente de pressão. Para isso é sugerido, que uma folga (11) seja prevista entre o anel de encosto de pressão (8) e o lado frontal (7) do pino de cilindro (2), que o anel de encosto de pressão (8) seja acoplado na bucha de pino (4), e que pelo menos um agente de pressão seja previsto na folga (11) para extração da bucha de pino (4) e do calço (6).
