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 V1, a cylinder volume (compression volume) when the piston reaches the top dead point is V2, the atmospheric pressure is P0, and the specified pressure is PP, the compression volume V2 in 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×{V1×P0/(PP?P0)}=<V2<1.

Abstract: In the present invention, a difference between a pressure displayed by a manometer of a compressor device and an actual internal pressure of a tire can be reduced. A compressor device (2) and a bottle unit (3) are directly connected. A cap (6) attached to the bottle unit (3) comprises a unidirectional valve (14) for preventing a reverse flow of a flat tire sealing agent to the side of the compressor device. A cylinder (12) of the compressor device (2) is provided with a pump chamber (11), and a surge chamber (18) which receives the compressed air from the pump chamber through an exhaust valve (16), wherein a volume (Q2) of the surge chamber (18) is 1.0 to 3.0 times of the stroke volume of a piston (10) in the pump chamber (11).

Abstract: A compressor apparatus notifies a user whether compressed-air reaches a specified pressure without requiring a pressure gauge or the costs associated therewith. The compressor apparatus includes a motor M, a rotational shaft 11, a compressor main body 10 comprising a cylinder chamber 15, and a detector 7 that notifies the user that the pressure of the compressed-air supplied from the above-mentioned cylinder chamber 15 exceeds a reference pressure P. The detector 7 includes a valve main body 30 having a valve flow channel 30A having an exhaust port 33 and a switch valve 34 releasing the valve flow channel 30A to exhaust the compressed-air supplied from the exhaust port 33 when the compressed-air pressure exceeds the reference pressure P; and a detective cap 31 pushed up by the exhaust air pressure from the exhaust port 33 from the normal position Y1 to the protruding position Y2.

Abstract: To carry out tire puncture repair and to inflate an air-inflation target object with solely compressed air, selectively by a changeover switch, so as to achieve greater versatility. A housing case 2 houses a compressor 3, a sealing agent container 6 in which a cap element 5 is attached to a mouth portion 4A of a container body 4 that stores a sealing agent, and a changeover switch 8 that is interposed between the compressor 3 and an air intake port portion 7 provided at the cap element 5. The changeover switch 8 has an in-flow port P0 into which compressed air from the compressor 3 flows, and first and second out-flow ports P1 and P2 that are selectively changed over to communicate with the in-flow port P0. The first out-flow port P1 and the air intake port portion 7 are connected to each other by a connection hose 75.
