Abstract
In a device for stroke end cushioning and speed regulating the movement of a piston (3) in a fluid pressure cylinder (1,2) a common adjusting means (9) is arranged for simultaneous setting of the throttle means (7,8) for regulating the stroke end cushioning as well as the piston speed, for the purpose of avoiding very time consuming adjustment. In connection with the setting of the adjusting means (9) the ratio between the flow areas of the respective throttle means is held within the range of 10-60%. In the most uncomplicated embodiment the common adjusting means (9) may be comprised by a screw being fixed to the valve bodies of the respective throttle means.
