とするエアシリンダ。It comprises a piston, a piston rod fixed to the piston at one end, and a cylinder in which the piston is slidably housed, and a seal ring housing groove is formed in the peripheral edge of the piston, and a seal ring housing groove is formed in the circumferential edge of the piston, and a seal ring housing groove is formed in the peripheral edge of the piston, and a piston rod is fixed to the piston at one end. In an oil-free air cylinder, a seal ring that maintains airtightness is stored in this storage groove together with lubricating oil, and the piston is caused to slide within the cylinder by introducing compressed air into the cylinder. An auxiliary plate is provided that is spaced apart from the piston and forms an oil reservoir in which lubricating oil is stored between the piston and the lubricating oil between the oil reservoir of the piston and the storage groove. A movable passage is formed in the peripheral portion of the piston, and the auxiliary plate deforms or moves in response to the difference in air pressure in the cylinder on both sides of the piston to drain the lubricating oil in the oil sump. An air cylinder characterized by supplying air to a seal ring storage groove.
