HYDRAULIC CYLINDER CUSHION DEVICE IN COVER END

摘要

PURPOSE: A hydraulic cylinder cushion apparatus for a cover end is provided to improve performance of a cushion even in case of excessive pressure. CONSTITUTION: A hydraulic cylinder cushion apparatus for a cover end comprises a throttle fluid path(31). The throttle fluid path is formed on the cover end(30) of the hydraulic cylinder. One or more of U-shaped or V-shaped notches are formed in the throttle fluid path. The buffer pressure power which prevents that piston and cover end drastically collide is occurred. When a piston(40) is moved to the cover end, a plunger is inserted into one end of a rod(20) of a cover end side.
