Abstract
A puncture repair kit that reduces the difference between a pressure displayed on a manometer of a compressor device and an actual tire internal pressure. The compressor device (2) is connected with a bottle unit (3) directly. A cap 6 comprises a one-way valve (14) to prevent puncture-sealing agent from flowing back toward the compressor device. A cylinder (12) of the compressor device (2) comprises a branch chamber (21) receiving compressed air from a pump chamber (11). The branch chamber (21) is connected with an air feeding passage (39) extending toward a bottle unit (3), a manometer (22), a relief valve (23), and a surge chamber (70) to store the compressed air from the pump chamber (11) and to reduce the pressure fluctuation of the compressed air.
Claims18
A puncture repair kit comprising
- a compressor device comprising a compressed air discharge port to discharge compressed air, and
- a bottle unit comprising
- a bottle container containing a puncture-sealing agent and
- a cap provided on an opening of the bottle container, wherein
- said cap comprises
- an air intake port capable of connecting directly to said compressed air discharge port and of sending the compressed air from the compressed air discharge port into the bottle container through a first flow channel,
- a sealing agent/compressed air outlet port to bring out in succession the puncture-sealing agent and the compressed air from said bottle container through the second flow channel by this sending of this compressed air, and
- said first flow channel provided with a one-way valve to prevent from the puncture-sealing agent from flowing back toward the compressor device;
- and
- said compressor device comprises a cylinder comprising a pump chamber to compress the air with a reciprocatory motion of a piston, and a branch chamber receiving the compressed air from the pump chamber;
- said branch chamber is connected to
- the air feeding passage sending the compressed air from the branch chamber to said compressed air discharge port,
- a manometer to measure a pressure of the compressed air, and
- a relief valve;
- and
- said branch chamber is connected to a surge chamber to reduce a pressure fluctuation of the compressed air by storing the compressed air from said pump chamber.
