Abstract

PURPOSE:To pump up oil from an oil sump as well as to make stable oiling performable, by installing suction oil passage to be interconnected to the oil sump, in a shaft part of a turning scroll, and having a pump built in space between a turning scroll shaft end and a driving shaft eccentric part. CONSTITUTION:An oil passage 2d to be interconnected to a bottom part 7a of a hermetically sealed vessel 7, is installed in a shaft 2c of a turning scroll 2, and a pump 9 is built in space between a shaft end of the turning scroll 2 and an eccentric hole part 5a of a driving shaft. And, oil is pumped up from a suction pipeline 19 dipped in an oil sump at the lower part of the vessel by the pump 9 through oil passages 3e, 6f, 5d and 2d, whereby the oil is fed to bearings 6a, 6d and 5d, and furthermore the discharged oil is fed to a bearing 6c by the pump 9 by way of an oil filler port 5c. Accordingly, stable oiling is performable under the low pressure ambience inside the vessel, thus reliability in the bearing is improved and, what is more, sufficient oiling for a wide range of operations can be done.

(Prior art) The conventional lubricating method is to form a discharge chamber enclosing a fixed scroll and a suction chamber enclosing an electric motor in an airtight container, as described in Utility Model Application Publication No. 59-882901. A discharge chamber is used to supply oil using the differential pressure between the discharge pressure and the suction pressure.However, with this structure, the oil is at a high temperature, so the viscosity decreases, making it difficult to form an oil film. No consideration was given to the fact that under operating conditions where the amount of heat generated from the pump is small and the differential pressure between the suction pressure and the discharge pressure is small, the amount of oil supplied cannot be ensured.
