Method and arrangement for fixing a piston (1), or a piston rod attachment, to a piston rod (5), one of the piston (1) and the piston rod (5) having a hole (2) running in its axial direction, and the other of these having a portion designed for being received by the hole (2) for connection of the piston (1) and the piston rod (5). The device includes an elongate locking means (10), at least one first opening (8a, 8b) in the piston and at least one second opening (9) in the piston rod (5), which openings (8a, 8b, 9) in the piston rod (5), which openings (8a, 8b, 9) extend in a different direction from the axial direction and are designed for receiving the locking means (10) for the purpose of bringing about the fixing. The elongate locking means (10) has a greater extent in its transverse direction, along at least a part of the means, than the extent of at least one of the openings (8a, 8b, 9) in its transverse direction, along at least a part thereof, for form locking between the locking means (10) and the opening. The invention also relates to a method for the fixing.
A releasable coupling arrangement configured for fixing a coupleable member to a piston rod, the arrangement comprising:
A method for fixing a piston or a piston rod attachment to a piston rod, at least one first opening being formed in the piston or the piston rod attachment and at least one second opening being formed in the piston rod in such a manner that their longitudinal directions differ from the axial direction of the piston or the piston rod attachment and, respectively, the piston rod, the openings being designed for receiving an elongate locking means for the purpose of bringing about the fixing, and the piston or the piston rod attachment being connected to the piston rod via a relative movement between these in their axial direction, the elongate locking means has a extent in its transverse direction, along at least a part of the means, than the extent of at least one of the openings in its transverse direction, along at least a part thereof, and in that the locking means is brought down into the openings for form locking between the locking means and the opening after the relative movement.
