Abstract:
Fluid pressure cylinder of the kind including a cylinder tube (23) with a slot and being shielded and sealed by an outer (11) and an inner (10) sealing band and with a cylinder bore (23') and a piston (2,5) which is movably arranged inside the tube and a transfer means (3) for transferring the piston movement through the slot to means (4) at the outside of the cylinder tube which are adapted to co-operate with an outer linear guide (21), wherein the piston at each piston end comprises on the one hand a seat (7) for a piston sealing member (6), on the other hand upper (14) and lower (13,15) guiding means for co-operation with said outer and inner sealing bands,characterized in that the piston comprises a central body (2) and two piston end units (5) surrounding the respective end of the piston body and lying (17) against the cylinder bore and comprising the piston sealing member (6) seat (7), wherein each piston end unit (5) is fitted with play (s) onto the body (2) in order to allow a relative movement between these elements and thereby the possibility of absorbing possible oblique angle between on the one hand elements (3,4) being connected to the piston and thereby the piston body (2), and on the other hand the cylinder bore (23').
