Title:
OIL SEPARATION DEVICE FOR CLOSED TYPE MOTOR DRIVEN COMPRESSOR
Document Type and Number:
Japanese Patent JP2556947
Kind Code:
B2
Abstract:
PURPOSE: To decrease bearing pressure applied from an inside face of a pin insertion hole to a side face of a pin for supporting an oil separation plate so as to prevent breakage of the pin and further restrain loosening of a caulking work part.
CONSTITUTION: Application of burring work 5a to a pin insertion hole 5 increases a contact area between a pin 3 and an inside face of the pin insertion hole 5 so that bearing force applied to a contact face for a unit area is decreased. By providing a groove 3a at a pin root part, a pin diameter at the time of caulking work is sufficiently expanded over a whole area of an inside face of the pin insertion hole 5 so that generation of loosening at a caulking work part can be restrained.
