Device for stroke end cushioning and speed regulating the movement of a piston in a fluid pressure cylinder

Device for stroke end cushioning and speed regulating the movement of a piston (3) in a fluid pressure cylinder (1,2), comprising at least one pair of adjustable throttle means (7,8;23.24;33,34) for throttling of the flow of fluid out from the cylinder, a first throttle means (7;23;33) in said pair for regulating the piston speed being arranged to throttle the outflow of flow through an outlet channel (12;37), a second throttle means (8;24;34) in said pair for stroke end cushioning being arranged to throttle the outflow of fluid through a separate stroke end cushioning channel (11;22;32), and means (5,6a;21;31;64,65) for sealing the flow directly to the first throttle means from a cushioning chamber, being formed in a certain mutual position between the cylinder end wall and the piston, forcing the outflow from said cushioning chamber to pass through the stroke end cushioning channel, characterized in that both of the throttle means in said pair are jointly adjustable by one adjusting means (9;25,26;35) in such a way that the ratio between the flow areas of the second and the first throttle means is held within the range of 10-60%.
