Abstract (en)
A scroll compressor is equipped with: a scroll compression mechanism that is housed in a housing and compresses a low-pressure gas; a motor that is linked to the scroll compression mechanism by a rotary shaft and that drives the scroll compression mechanism; an upper bearing and a lower bearing that support the rotary shaft in a rotatable manner; and an oil supply pump that draws in lubricating oil due to the rotation of the rotary shaft and supplies the lubricating oil to sliding parts. The oil supply pump is a positive-displacement pump which is capable of operating in an operating region wherein the rotational frequency of the motor is 150 rps or higher, and for which an inclination indicating the rate of increase in the amount of oil supplied per unit time with respect to the rotational frequency decreases as the rotational frequency increases.
