Abstract

PURPOSE: In a shaft sealing device used for a hydraulic circuit or the like for the purpose of protecting valve housing and spool frictional sections, to protect the frictional surface of a piston section by mounting a porous elastic member impregnated with lublicant on the piston outer end.
CONSTITUTION: A ring-like porous elastic member 14 having a cental hole 19 is fitted on an outer end portion of a piston 15 fitted in a hole 17 of a cylinder body 18, and its outer end is covered with a seat member 12 fitted on and secured to the piston 15. The piston 15 is urged toward the inside of the cylinder body 18 by a compression spring 11 engaging with the seat plate 12, and the other end of the elastic member 11 is thus elastically engaged with the end 18 of the cylinder body 18. Since the stroke of the piston 18 is small, the end surface 16 of the cylinder body 18 and the outer periphery of the portion of the piston 15 extending from the hole 17 can be completely sealed by the porous elastic material 14 if the extent of compression of the porous elastic material 14 is greater than the stroke.
