Abstract
Official abstract text for this publication.
A fluid supply apparatus that can eliminate the need for a power supply source, and store fluid efficiently. The apparatus may comprise a first balloon that is formed of an elastic body to be capable of storing the fluid, a second balloon that is formed of an elastic body to be capable of storing the fluid, and has a larger contraction force than a contraction force of the first balloon, a support member that supports both of the first balloon and the second balloon, and a casing that houses the first balloon and the second balloon, and defines inflation ranges of the first balloon and the second balloon, in which the support member has a flow path formed to permit fluid communication between an interior of the first balloon and an interior of the second balloon.
First claim
Opening claim text (preview).
What is claimed is: 1. A fluid supply apparatus for supplying stored fluid to outside, comprising: a first balloon that is formed of an elastic body to be capable of storing the fluid; a second balloon that is formed of an elastic body to be capable of storing the fluid, and has a larger contraction force than a contraction force of the first balloon; a support member that supports both of the first balloon and the second balloon; and a casing that houses the first balloon and the second balloon, and defines inflation ranges of the first balloon and the second balloon, wherein the support member has a flow path formed to permit fluid communication between an interior of the first balloon and an interior of the second balloon, and wherein the support member is a tubular member and extends through the first balloon and the second balloon. 2. The fluid supply apparatus according to claim 1 , wherein the support member includes a connection portion that connects an end of the first balloon and an end of the second balloon, the ends being adjacent to each other, and the flow path is formed in the connection portion. 3. The fluid supply apparatus according to claim 1 , wherein the support member extends from one end to the other end of the casing. 4. The fluid supply apparatus according to claim 1 , wherein the support member has a plate shape, and the first balloon is attached to one surface of the support member and the second balloon is attached to the other surface of the support member. 5. The fluid supply apparatus according to claim 1 , wherein the casing is provided with a sensor for detecting that at least one of the first balloon and the second balloon has contacted the casing. 6. The fluid supply apparatus according to claim 1 , wherein the first balloon and the second balloon are different from each other in thickness. 7. The fluid supply apparatus according to claim 1 , wherein the first balloon and the second balloon are different from each other in inner diameter. 8. The fluid supply apparatus according to claim 1 , wherein the first balloon and the second balloon are different from each other in length. 9. A fluid supply apparatus for supplying stored fluid to outside, comprising: a first unit that comprises a first balloon that is formed of an elastic body to be capable of storing the fluid, a first support member that supports the first balloon, and a first casing that houses the first balloon and defines an inflation range of the first balloon; and a second unit that comprises a second balloon that is formed of an elastic body to be capable of storing the fluid and has a larger contraction force than a contraction force of the first balloon, a second support member that supports the second balloon, and a second casing that houses the second balloon and defines an inflation range of the second balloon, wherein the first support member and the second support member have a flow path formed to permit fluid communication between an interior of the first balloon and an interior of the second balloon. 10. The fluid supply apparatus according to claim 9 , wherein the first casing is provided with a sensor for detecting that the first balloon has contacted the first casing. 11. The fluid supply apparatus according to claim 9 , wherein the second casing is provided with a sensor for detecting that the second balloon has contacted the second casing. 12. The fluid supply apparatus according to claim 9 , wherein the first balloon and the second balloon are different from each other in thickness. 13. The fluid supply apparatus according to claim 9 , wherein the first balloon and the second balloon are different from each other in inner diameter. 14. The fluid supply apparatus according to claim 9 , wherein the first balloon and the second balloon are different from each other in length.
