<p>PURPOSE: To automatically adjust lubricant supply quantity by providing an oil supply control device to control the supply of lubricant according to the quantity and delivery pressure of the lubricant delivered from a delivery port for keeping the air tightness between stationary and orbit scrolls. CONSTITUTION: The upper peripheral edge of the stationary scroll 26 of a scroll compressor is formed into a tapered shape so that the lubricant in a delivery chamber 5 can be collected, and a chamber 18 is formed near the peripheral edge of this stationary scroll 26 to reserve lubricant. In this chamber 18, a pressurizing valve 10 to control oil supply is provided so as to be energized upward by a spring 9 in a small diameter container section 18b. On the other hand, on the upper face of an orbit scroll 24, a container section 12 is formed to smoothly supply the lubricant reserved in the chamber 18 to each drive section of a compressor body, and a cut off valve 13, which is connected to the pressurizing valve 10 through a support bar 14 in this container section 12, is arranged slidably along the inclined face 12a of the upper face of the orbit scroll 24.</p> |
