シリンダのクツシヨン装置。 A housing, a piston rod reciprocably housed within the housing, a piston attached to the piston rod, and a groove that fits into the outer periphery of the piston rod and whose depth gradually decreases in the axial direction. A cushion ring is formed on the outer periphery of the piston, and at the end of the stroke of the piston, the cushion ring enters a hole formed in the housing side and gradually narrows the variable throttle formed by the hole and the groove. In a hydraulic cylinder cushion device, a communication space is formed between the cushion ring and the piston rod, a ring member is provided in the communication space, and a ring member is provided in the communication space.
A hydraulic cylinder cushion device has an orifice formed in this ring member.
