Abstract

PURPOSE:To improve cooling efficiency from allowing a friction heat generated between piston rod and sealing member to escape with a heat of vaporization of refrigerant by sealing the refrigerant in a hollow provided in the piston rod. CONSTITUTION:A hollow 7a is formed at the end of cross heat 6 side in a piston rod 7, and the hollow is filled with a refrigerant 19 consisting of a mixed solution of water, fron, alcohol, etc. nearly half of the hollow volume. When the piston rod 7 moves vertically, the refrigerant 19 becomes a mist 19a partly in the hollow 7a full. And when the mist 19a comes in contact with a piston rod high temperature zone 7b around a main seal 11, it works are heat of vaporization to take away the heat generated by friction between the piston rod 7 and the main seal 11. when the vaporized refrigerant gas comes in contact with a piston rod low temperature zone 7c, it discharges the heat to the low temperature zone 7c and condenses to revert to liquid. Thut the friction heat generated at the main seal 11 is cooled down efficiently by the refrigerant 19.
