COLLECTION STRUCTURE FOR LEAKED OIL IN COMPRESSOR

摘要

PROBLEM TO BE SOLVED: To drop leaked oil running on a drive shaft at a specified position of a space in a housing in simple structure without increasing the number of parts. SOLUTION: A damming member 35 is fixed on an opening side of a boss part 16 rather than a lip seal 17 on an inner peripheral surface of the boss part 16. An oil absorbent member 36 is stored and arranged in a storage part 37 of a front housing 11. An oilleading passage 38 is connected to an inside space of the oil absorbent member 36 and the boss part 16. The same oil leading passage 38 is opened between the damming member 35 and the lip seal 17. A ring groove 39 is peripherally provided at a position corresponding to a part between the lip seal 17 and the damming member 35 at a small diametrical portion 15r of a drive shaft 15. Additionally, a step difference on the side of the lip seal 17 constituting the same ring groove 39 makes a step difference part 40. It is possible to shake off leaked lubricating oil running on an outer peripheral surface of the drive shaft 15 at a specified position by the same step difference part 40.
