SPEED RESPONSIVE DAMPER AND IMPACT ABSORBING DAMPER DEVICE

摘要

A speed responsive damper (10) comprises: a cylinder (11) in which a fluid is enclosed; a piston (13) that is slidably fitted into the cylinder and that has an orifice (19a) through which a fluid passes; a piston rod 14 whose one end is fixed to the piston and whose the other end is extended to the outside of the cylinder; and a slider 15 that is installed within the cylinder, and that moves in a predetermined range relative to the piston, and that adjusts an amount of the fluid passing through the piston, wherein the orifice is formed at a front end side of the piston. Therefore, explosive sound of air can be reduced, and swirl or slip of oil can be previously prevented, and a piston rod can be prevented from tilting.
