Abstract
Apparatus and methods for tire inflation using an apparatus. The apparatus contains a piston in a housing and a bladder attached at an end of the housing. The apparatus is configured to compress air between a cap, the housing, and piston from the bladder compressing. Air enters into the tire through a valve in the piston. When the bladder decompresses, the piston seals air in the tire, thereby enabling air to pass through the valve in the cap. The apparatus involves a method of maintaining air pressure in a tire. The method includes the apparatus for inflating the tire as the tire rotates over a surface.
Claims7
The tire inflation apparatus comprising:
- a housing configured to be embedded inside a tire, the housing comprising one or more apertures, wherein the housing comprises a first end and a second end;
- a piston disposed within the housing, the piston comprising one or more chambers, wherein the one or more chambers are configured to be in fluid communication with the one or more apertures;
- a spring disposed within a housing chamber in the housing, wherein a volume between a first end of the piston and the first end of the housing defines the housing chamber, and wherein the spring is configured to place the piston between at various positions along a length of the housing;
- and
- a bladder coupled to the second end of the housing, the second end opposing the first end, wherein a volume of the bladder is configured to be in fluid communication with the one or more chambers.
A method of maintaining air pressure in a tire, the method comprising:
- embedding a tire inflation apparatus inside of the tire, the tire inflation apparatus comprising:
- a housing comprising one or more apertures, wherein the housing comprises a first end and a second end,
- a piston disposed within the housing, the piston comprising one or more chambers, wherein the one or more chambers are configured to be in fluid communication with the one or more apertures,
- a spring disposed within a housing chamber in the housing, wherein a volume between a first end of the piston and the first end of the housing defines the housing chamber, and wherein the spring is configured to maintain the piston at various positions along a length of the housing, and
- a bladder coupled to the second end of the housing, wherein a volume of the bladder is configured to be in fluid communication with the one or more chambers;
- sealing air in the bladder when the bladder and the one or more chambers have the same air pressure, wherein the air in the bladder urges the piston to a position such that the one or more chambers of the piston are not in fluid communication with the one or more apertures of the housing;
- forcing air into the tire from the one or more chambers when the bladder is compressed, whereby the compressed bladder forces air into the chamber and urges the piston to a position such that the one or more chambers of the piston are in fluid communication with the tire via the one or more apertures of the housing;
- and
- forcing air into the housing chamber through an exposed end of the housing when the housing chamber has a lower air pressure than ambient air pressure, thereby enabling air to be forced into the tire via the piston when the bladder is subsequently compressed.
