摘要： An oil-flooded screw compressor drives a pair of rotors at a rotational speed which is low enough not to increase torque for a short amount of time after start-up and accelerates the pair of rotors up to a normal-operation rotational speed after oil discharge. Alternatively, the oil-flooded screw compressor rotates the pair of rotors for a short amount of time after the remaining compressed gas is discharged after a halt, thereby allowing the oil accumulated inside the working chambers to be discharged and ensuring smooth start-up after the halt.

摘要： An ink jet printer which uses a common air pump to configure an air path system to supply purge air generated by the air pump to an ink tank and then supply the purge air discharged from the ink tank to a print head or an air path system to supply purge air generated by the air pump directly to the pint head. This solves the following problem inherent to a conventional ink jet printer which recovers ink not used for printing: since an air pump for supplying air to air-purge the print head and an air pump for supplying air to air-purge the ink tank are required, the cost and weight of the printer tends to increase.

摘要： A high reliability water injected scroll air compressor is provided with an orbiting scroll, a fixed scroll corresponding to the orbiting scroll, a motor that generates driving force for making the orbiting scroll orbit the fixed scroll, a compressing path from a suction port to a discharge port, and a portion for injecting water into the compressing path. The operation is controlled by a switching operation in which water is injected into the compressing path and then no water is injected. Corrosion, failure of activation, and concerns about wrap contact when water is injected into an air end are avoided by switching the operation with water injection and the operation without water injection so as to prevent water from remaining in the air end.
