Lubricant supply system of a scroll fluid machine |
摘要 |
A scroll compressor has a scroll mechanism disposed in a closed container and driven by a motor through a crank shaft rotatably supported at two points by first and second bearings disposed adjacent the opposite ends of the motor. The bearing which is remote from the scroll mechanism comprises a sliding bearing. The first end of the crank shaft remote from the scroll mechanism has a peripheral surface disposed in sliding engagement with the sliding bearing and formed therein with a lubricant supply groove communicated with an axial lubricant supply hole formed in the crank shaft and having a closed end adjacent the first end of the crank shaft and opened in an end face of a crank pin section thereof. The sliding bearing is communicated with a lubricant reservoir formed by a lower part of the container. The lubricant in the reservoir is subjected to the pressure of a compressed fluid discharged from the scroll mechanism and is forcibly fed into the lubricant supply groove through the sliding bearing.
