ド。 In a cylinder rod that is driven up and down in the cylinder by controlling the rod's own weight and the differential pressure of the fluid acting on the top and bottom of the rod, the outer periphery of the tip of the rod is moved up and down by a circumferential groove that communicates with the low pressure side. divide,
A plurality of pockets are provided circumferentially or axially on the outer periphery of the divided low-pressure side rod tip, and orifice plates are installed in the pockets, and axial pockets are provided near the outer periphery of the divided high-pressure side rod tip. A water supply hole communicating from the high pressure side to the low pressure side is bored in the cylinder, and the high pressure fluid passing through the water supply hole is guided into the pocket through the orifice plate, and further flows out into the radial gap between the cylinder and the rod. A cylinder rod characterized by its structure.
