ABSTRACT:
A shuttle piston cylinder includes a piston reciprocating in axial direction within the cylinder and carrying a transmission element which transmits the movement of the piston to a consumer and extends through a longitudinal slot of the cylinder barrel. A sealing band extends within the slot with one side stationary arranged against one wall of the slot and including two spaced flexible sealing lips which seal the slot towards the inside and the exterior by lying against the other wall of the slot. The transmission element is provided with slantingly extending shanks which during passage of this element lift the sealing lips from the sealing surfaces. Through inherent prestress, the sealing lips again are arranged on the sealing surfaces after passage of the transmission element.
