Weberation. In hydraulic cylinders, special shaping or contour-ing of the cushion spear or sleeve has been employed to provide programmed deceleration for the unit. Design of Cylinder Cushions – In cushioning of hydraulic cylinders, the spear or sleeve closes the main exhaust passage in the cylinder head or cap, confining the fluid WebThe cylinder incorporates a cushion seal in the end cap, which traps a small volume of air between the piston and the end position, providing a controlled deceleration of the piston at the end of the stroke. The braking effect is determined by a needle valve that exhausts trapped air near the end cap. Users can tune the valve with an adjusting ... dailymotion flipped
