Abstract

PURPOSE: To effectively lubricate a spherical bearing portion by forming an oil hole inside a rod of spheric axle into a tiered hole whose diameter becomes gradually larger from the large end portion of the rod to the spherical side in a full-enclose type ball joint compressor.
CONSTITUTION: An oil supply hole through which the inside of the large end portion 20a of the rod 20 is connected with the spherical bearing portion 20b is formed into the tiered hole 20d those diameter becomes gradually larger from the large end portion 20a toward the spherical side. Thus, the oil 8 intermittently supplied to the oil hole 20c near top dead center of piston is stayed on the tiered wall 20e during the forward stroke of piston but is advanced during the downward stroke of piston, so that the supply of oil to the spherical bearing portion 20b can be secured.
