Title:
SCROLL COMPRESSOR
Document Type and Number:
Japanese Patent JP3635732
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To smoothly discharge refrigerant gas staying in an oil passage, and smooth oil supply to a slidingly movable part by arranging radial directional holes leading to a sealed positive air space after proceeding in the almost shaft center direction in the middle of oil holes bored in the almost axial direction in positions separate from its shaft center in a crankshaft.
SOLUTION: Two oil holes 15a and 15b penetrating toward an upper end hole part 3a close to the lower end on which an oil pump part is installed are bored in a crankshaft 7. These oil holes 15a and 15b are bored in a slightly slant posture in the shaft direction, and separate from the shaft center as they proceed to the hole part 3a. Radial directional holes 20a and 20b leading to the oil holes 15a and 15b are bored between a bearing part 6 of a central part of the crankshaft and a rotor 12a of an electric motor. These radial directional holes 20a and 20b are bored in positions dislocated in the vertical direction so as to be opened in a sealed space after proceeding in the one end shaft center direction from the oil holes.
