Title:
METHOD FOR USING ONE-WAY VALVES FOR BLOWOUT PREVENTION TIRE
Document Type and Number:
WIPO Patent Application WO/2018/099444
Kind Code:
A1
Abstract:
A method for using one-way valves for a blowout prevention tire. The blowout prevention tire comprises a wheel rim (1), an outer tire (2), inner tires (3), and one-way valves (37). The one-way valves (37) comprise a first one-way valve (6) and a second one-way valve (7). The first one-way valve (6) comprises a first valve body (38), a first spool (39), a first spring (40), and a first drive plate (41), and the second one-way valve (7) comprises a second valve body (42), a second spool (43), a second spring (44), and a second drive plate (45). In use, when the outer tire (2) is inflated, the first one-way valve (6) inflates the first inner tire (4). After the first inner tire (4) is inflated, the second one-way valve (7) inflates the second inner tire (5). When the outer tire (2) loses a pressure, the first one-way valve (6) is closed and the first inner tire (4) supports the outer tire (2) by means of a first outer supporting column (17) and a first inner supporting column (18). When the outer tire (2) and the first inner tire (4) lose pressures, the second one-way valve (7) is closed and the second inner tire (5) supports the outer tire (2) by means of the first outer supporting column (17), the first inner supporting column (18), a second outer supporting column (19) and the second inner supporting column (20), so as to reduce occurrence of flat tire accidents.
