Abstract

PURPOSE:To improve the performance of a differential pressure pump, eliminate the delay of oil feeding for a bearing immediately after starting to prevent seizing trouble of the bearing by extracting refrigerant gas staying in a distributor in the differential pressure pump. CONSTITUTION:Four sets of gas extracting holes 20, whose one end can be communicated with the opening of oil feeding hole 14 of a rotating scroll 6 and the other end thereof is communicated with a suction chamber 19, are provided in a fixed scroll 5 with equal spaces. At every one rotation of the rotating scroll 6, the oil supplying hole 14 is communicated with the suction chamber 19 through respective gas extracting holes 20. Accordingly, the refrigerant gas, introduced into the distributing part 15 together with lubricating oil, is introduced into the suction chamber 19 through the gas extracting holes 20. According to this method, the refrigerant gas will never stay in the distributing part 15 and the flow of the lubricating oil to the sliding surface 13 of both scrolls will never be precluded, therefore, the performance of the differential pressure pump may be improved and delay of oil feeding for the bearing immediately after starting may be eliminated thereby enabling to prevent the seizure trouble of the bearing.
