Abstract: PURPOSE: A scroll compressor and the driving method are provided to exhibit high efficiency and high reliability with easy and inexpensive structure. CONSTITUTION: In addition to the suction, compression and delivery of a fluid by making a rotating scroll(2) of a compression mechanism part(14) take a circular orbital motion to a fixed scroll(1). The liquid is supplied from a liquid drip pan(25) provided on the other end side of a shaft(8) through the shaft for driving the rotating scroll on one end side to the compression mechanism part followed by lubrication, and then supplied to the back part of the rotating scroll to make a back pressure for pressing the rotating scroll to the fixed scroll side act thereon. Intermittent communication in two positions in a liquid supplying route(100), or intermittent communication in one position in a liquid release route(103) and intermittent communication in one position in the liquid supplying route are performed according to the rotation of the shaft to adjust the supplying quantity or release quantity of the liquid to a back pressure working area(32). The drive is performed while keeping the back pressure in a prescribed range.
