    摘要： The patent application discloses a method of compressing air. The method for designing a more efficient reciprocating piston compressor comprising the steps of: providing an air compressor having a first compression stage adapted for compressing gas from a low pressure to an intermediate pressure and including a first piston connected to reciprocate in a first cylinder, a second compression stage adapted for compressing gas from the intermediate pressure to a higher pressure and including a second piston connected to reciprocate in a second cylinder, and a motor connected to reciprocate said first piston in said first cylinder over a stroke and said second piston in said second cylinder over a stroke; and establishing a sufficiently fewer number of strokes over which the gas to be pressured starting from the atmosphere pressure.

    摘要： An air suspension device includes an exterior compressed air source (9) that is mounted on a pressure accumulation tank (50) to supply compressed air, and a control unit (ECU) that controls a compressor device (CMP) to boost air pressure within the pressure accumulation tank (50) to fill an air spring device (A1, A2, A3, A4) with the compressed air, the control unit (ECU) controlling first and second inlet and outlet on-off valves (71, 72), first and second tank on-off valves (81, 82), and control valve (61, 62, 63, 64) to supply at least compressed air within the air spring device (A1, A2, A3, A4) to the pressure accumulation tank (50) when a pressure level of air within the air spring device (A1, A2, A3, A4) comes to be greater than a predetermined pressure level, or when a vehicle height value comes to be greater than a predetermined value.
