To control compressed air to a prescribed pressure without using a relief valve and a chamber and to suppress deviation of the pressure. A compressor deviceof a puncture repair kithas a pressure gauge. The pressure gaugehas a tubular body portionprovided in a front end portion with a communicating holecommunicating with a surge chamberB, a pistonmovable within the tubular body portionin the longitudinal direction by the compressed air from the communicating hole, and a springbiasing the pistontoward the front end and changing its displacement according to the magnitude of the pressure of the compressed air. An exhaust portis formed on the peripheral wall of the tubular body portion. The exhaust portreleases the compressed air when a seal ringof the pistonexceeds the exhaust port

Tire puncture repair kit

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&#xd7;{1&#xd7;/()}=&#x3c;2&#x3c;1.0&#xd7;{1&#xd7;/()}&#x2003;&#x2003;(1)

Compressor system, and puncture repair kit using same

A compact simplified compressor apparatus is provided with a rotating shaft rotationally driven by a motor, a compact compressor activated by the rotating shaft, an air feeding means for feeding a high-pressure air from the compact compressor to a tire, and a power source plug supplying an electricity to the motor. The compact compressor is provided with a rod attached to the rotating shaft via a crank, a piston having a peripheral groove in an outer peripheral surface and integrally formed with the rod, a cylinder having a cylinder chamber receiving the piston so as to freely reciprocate, and a ring seal sealing between the piston and an inner peripheral surface of the cylinder chamber. The ring seal is provided with a base portion having a base surface seating on a groove wall surface in the rod side of the peripheral groove, and inner and outer lip portions, each extending from the base portion toward radially inside and outside so as to be opened toward the opposite rod side.
