Abstract:
PURPOSE: To prevent the quick movement of a sliding door.
CONSTITUTION: A piston 12 having a check valve 14 in the through-hole 13 of a head section 12a and a rack 15 in a side section 12b is fitted slidably to a cylinder 1. The piston is energized toward a compression chamber 16a by springs 17, 18 attached on the spring chamber 16b side in a contracted warmer, the shaft 22 of a pinion 21 engaged with the rack 15 is borne rotatably to a cylinder wall, and the compression chamber and the spring chamber are communicated by oil paths 19, 20 in the cylinder wall. The door closure is provided droopingly while the compression chamber side is directed to an upper section, and the other end of an opening-closing arm, in which one end is fixed onto a pinion shaft 22, is fitted slidably to sliding fittings fastened along the edge of a sliding door. One end P2 of the oil path 20 is opened to a section just above the surface of a working fluid in the compression chamber at a working maximum temperature, and an air chamber 3 is mounted while being communicated with the compression chamber 16a in the upper section of the opening. An air relief valve 10 receiving the buoyancy of the working fluid and being closed is installed so as to partition the air chamber 3 and the compression chamber 16a.
