HYDRAULIC DAMPING DEVICE, HINGE ARRANGEMENT, AND MACHINE
A hydraulic damping device comprising a housing (2) having a cylinder space (3) defined by a cylindrical inner wall (4) of the housing, a piston (7) arranged movably in the cylinder space (3), a piston rod (8) arranged to the piston (7) and extending to the outside of the housing (2), means for moving the piston (7) from a first position, in which the piston rod (8) is in a retracted position, to the second position, in which the piston rod (8) is in an extended position, and a fluid tank (20) operationally connected via fluid channel (19) to the cylinder space (3). The damping device (1) is configured to damp a movement of the piston (7) and the piston rod (8) from the extended position of the piston rod (8) to the retracted position of the piston rod (8) achieved by an external force directed to the piston rod (8), wherein a fluid flow is achieved by pressing the fluid with the piston (7) from the cylinder space (3) to the fluid tank (20) via the fluid channel (19), and the device comprises means for returning the piston (7) to the extended position of the piston rod (8) when the external force is not directed to the piston rod. The invention relates also to a hinge arrangement and a machine.
