摘要： A claw pump includes: a housing; two rotating shafts which are disposed parallel; a pair of rotors respectively fixed to the two rotating shafts; a rotary drive device driving the pair of rotors; and a suction port and discharge ports formed in a partition wall of the housing. The discharge ports are constituted by a first discharge port and a second discharge port. The first discharge port is formed at a position that communicates with an initial stage compression space formed at an initial stage of a compression stroke in a compression space that is formed by joining a first pocket and a second pocket. The claw pump includes an opening/closing mechanism which opens the first discharge port when a pressure of the initial stage compression space reaches a threshold and closes the first discharge port when the pressure does not reach the threshold.

摘要： A compressed gas supply unit has scroll compressors. Gas discharged from the scroll compressors travels through a main supply passage and is reserved in a reservoir tank, after which the gas is supplied to a gas recipient from a supply passage. The scroll compressors include inverter devices that allow for independent modulation of the speeds of respective drive motors. The controller includes a speed range setting unit that sets an upper speed limit and a lower speed limit of the scroll compressors, a speed sum calculating unit that calculates a sum of speeds of the scroll compressors based on a load of the compressed gas supply unit, and a speed setting unit that allocates the calculated sum of speeds among the scroll compressors to set speeds for scroll compressors respectively.
