Abstract
PURPOSE: To promote the accuracy of shaft seal by providing two distant pieces adjacently and applying a bellows on their circumferential areas for hermetically enclosing the gas leaking from the through hole of a piston rod.
CONSTITUTION: One end 51 of a bellows 50 is fast fixed on a side 3111 of the second distant piece 40 around a rod-penetrating hole 311 of a piston rod 21 drilled on a partition wall 31 which separates the first distant piece 40, and the other end 52 is fast fixed on a lid 60 attached to the rod 21 in the second distant piece 40. Consequently, a very small amount of gas leaking in the second distant piece 40 through the piston-rod-penetrating hole 311 on the partition wall 31 is hermetically enclosed in the bellows 50, while the gas in the bellows 50 is communicated from an exhaust pipe 161 to the atmospheric pressure via a small hole 18. In this construction, the gas in a cylinder 10 is prevented from leaking in the second distant piece 40.
