Abstract
A Re-Inflatable tire and inner tube system comprising of a primary flexible inflatable chamber and at least one secondary flexible inflatable chamber housed within the primary flexible inflatable chamber wherein all chambers share a single common inflation valve and wherein pressure is administered and controlled through the common valve to inflate one chamber at a time, independent and separate from all other chambers, while simultaneously releasing pressure from the chambers not being inflated.
Claims20
An inner tube assembly (9) comprising
- a primary outer flexible annular tube (10),
- at least one secondary internal inflatable chamber (11) housed and sealed within the primary outer flexible annular tube (10), and
- a single common inflation valve (8) having selective fluid communication with all associated flexible tubes and chambers;
- wherein the valve (8) selectively supplies and controls the administration of pressure to each selected tube or chamber independently and separately from the other tube or chamber not selected;
- and
- wherein pressure releases simultaneously to the atmosphere from the primary outer flexible annular tube (10) not selected, as pressure is supplied to the secondary internal inflatable chamber (11) which is selected.
An adjustable pressure distribution valve (8) comprising:
- a first primary external pressure administration port (15);
- a valve housing (16) which encompasses part of the first primary external pressure administration port (15),
- wherein the valve housing (16) has multiple secondary pressure administration ports (18)(19) and at least one pressure relief port (17),
- wherein the first primary external pressure administration port (15) is adjusted to selectively communicate with one or more of the secondary pressure administration ports (18)(19) within the valve housing (16),
- wherein the pressure relief port (17) is engaged by the selection of one of the secondary pressure administration ports (18)(19) within the valve housing (16),
- wherein at least one of the secondary pressure administration ports (18) not selected, is in fluid communication with the pressure relief port (17).
A method for administering pressure within a primary object (10) comprising:
- applying pressure through a common valve (8) to one or more secondary flexible inflatable objects (11) housed within the primary object (10) and independent of the primary object (10);
- wherein the inflation of the secondary flexible object (11) causes fluid displacement within the primary object (10) resulting in increased pressure between the outer surface of the secondary flexible object (11) and the inner surface of the primary object (10);
- wherein the increased pressure between the outer surface of the secondary flexible object (11) and the inner surface of the primary object (10) is simultaneously expelled through a relief port (17) located on the common valve assembly (8) as the secondary flexible object (11) inflates and expands displacing fluid within the primary object (10),
- wherein all of the pressure between the outer surface of the secondary flexible object (11) and the inner surface of the primary object (10) is expelled, eliminating all space between the outer surface of the secondary flexible object (11) and the inner surface of the primary object (10) resulting in pressure being applied to the inner surface of the primary object (10) by the outer surface of the secondary flexible inflatable object (11).
