Abstract
The pressure of compressed air supplied to an object to be filled with air is controlled at a specified pressure or less without using a relief valve. Given that a cylinder volume (stroke volume) during a piston moves from the lower dead point to the top dead point is V, a cylinder volume (compression volume) when the piston reaches the top dead point is V, the atmospheric pressure is P, and the specified pressure is P, the compression volume Vin the compressor system satisfies the following expression (1). The diameter D of the air intake hole of an air intake valve provided on the piston is 3 to 15 mm.0.8×{1×/()}=<2<1.0×{1×/()}  (1)
