Abstract

See full text

A semi-spherical shoe 1 includes a semi-spherical surface 1A and a flat end face 1B. The semi-spherical surface 1A comprises a sliding contact region 1a which is disposed in sliding contact with a semi-spherical recess 2B formed in a piston 2, and a lead-in 1b which is located above the sliding contact region 1a or disposed toward a top (recess 1C) of the semi-spherical shoe. The lead-in 1b has a diameter D2 which is greater than the diameter D1 of the sliding contact region 1a, thereby allowing a clearance 8 to be produced between lead-in 1b and an opposing portion of the semi-spherical recess 2B in the piston 2. A reservoir of lubricant oil in a space 4 formed between the semi-spherical recess 2B and the recess 1C of the semi-spherical shoe 1 is introduced into the sliding contact region 1a through the clearance 8. A sliding system having an excellent sliding response over the prior art is provided.
