Abstract

A fluid drive means for a linear reciprocating motion is provided with at least one flexible and collapsible member (15) arranged between elements (11, 12, 14) which move in relation to each other during operation. The member (15) surrounds between said elements (11, 12, 14) a central rod (13), which extends through one of the elements (11, 12). Together with the rod the member (15) completely delimits a fluid chamber for the pressure fluid which is required for the operation of the drive means. The member (15), which is made for instance of an elastomer, consists of a roll-membrane and establishes a sealing (19) around the rod (13).
