Patent number: 10307978Abstract: 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 device 2 of a puncture repair kit 1 has a pressure gauge 6. The pressure gauge 6 has a tubular body portion 18 provided in a front end portion with a communicating hole 21 communicating with a surge chamber 12B, a piston 19 movable within the tubular body portion 18 in the longitudinal direction by the compressed air from the communicating hole 21, and a spring 20 biasing the piston 19 toward the front end and changing its displacement according to the magnitude of the pressure of the compressed air. An exhaust port 25 is formed on the peripheral wall of the tubular body portion 18. The exhaust port 25 releases the compressed air when a seal ring 23 of the piston 19 exceeds the exhaust port 25.Type: GrantFiled: December 3, 2014Date of Patent: June 4, 2019Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., UNIK WORLD IND.

Patent number: 9956730Abstract: 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.Type: GrantFiled: October 18, 2013Date of Patent: May 1, 2018Assignees: SUMITOMO RUBBER INDUSTRIES, LTD., UNIK WORLD IND.

Patent number: 8997801Abstract: Disclosed is a puncture repair kit in which a bottle unit is positioned with greater stability. A puncture repair kit (1) comprises a compressor device (2), and a bottle unit (3) in which a cap (6) is attached to an opening (5) in a bottle container (4) which houses a puncture sealing agent. The compressor device (2) comprises a compressed air discharge port (8). The cap (6) comprises an air intake port (27) for feeding compressed air from the compressed air discharge port (8) into the bottle container (4), and a sealing agent/compressed air removal port (7) for removing puncture sealing agent and compressed air in succession from the bottle container (4) by feeding in compressed air. The compressed air discharge port (8) and the air intake port (27) can be directly connected.Type: GrantFiled: October 20, 2010Date of Patent: April 7, 2015Assignees: Sumitomo Rubber Industries, Ltd., Unik World Ind.

Patent number: 8684046Abstract: A puncture repair kit has a bottle unit positioned with greater stability. A puncture repair kit includes a compressor device, and a bottle unit in which a cap is attached to an opening in a bottle container which houses a puncture sealing agent. The compressor device includes a compressed air discharge port. The cap includes an air intake port for feeding compressed air from the compressed air discharge port into the bottle container, and a sealing agent/compressed air removal port for removing puncture sealing agent and compressed air in succession from the bottle container by feeding in compressed air. When the cap of the bottle unit is oriented downwards, the air intake port is directly connected with the compressed air discharge port. When this direct connection is made, the basal plane of the cap and the basal plane of the compressor device are flush with each other.Type: GrantFiled: October 20, 2010Date of Patent: April 1, 2014Assignees: Sumitomo Rubber Industries, Ltd., Unik World Ind.
