Abstract

"MOLA DE PRESSãO COM COMPRIMENTO AJUSTáVEL". Uma mola de pressão possui uma caixa (1) onde é disposto de modo deslocável um êmbolo (12) fixado em uma biela do êmbolo (8). Na caixa (1) são previstos dois compartimentos parciais da caixa (15, 16) cheios de fluido de pressão, dos quais pelo menos um é delimitado pelo êmbolo (12). Uma primeira válvula acionável (20) interliga os compartimentos parciais da caixa (15, 16) em uma posição aberta e bloqueia a mola de pressão em uma posição de fechamento. Através de uma válvula automática (41) adicional entre os compartimentos parciais da caixa (15, 16) pode ser deslocada a mola de pressão sob aplicação de uma força que pode ser comparada com a força de empuxo para fora que age através da pressão do fluido de pressão em direção de empuxe para fora da biela do êmbolo (36a), também em estado bloqueado, em direção de empuxo para fora (36a). Isto aumenta a flexibilidade de utilização da mola de pressão.
