초록 ▼

A resilient expandable pressure vessel configured to function like a spring. The resilient expandable pressure vessel includes a body portion, a cavity defined within the body portion, and at least one port in communication with the cavity defined in the body portion. The at least one port is configured to receive a fluid into the cavity and discharge the fluid from the cavity. The resilient expandable pressure vessel has a predetermined expansibility across a range of operating pressures of the fluid in the cavity. The range is at least 200 psi.

1. A resilient expandable pressure vessel, comprising: a body portion;a cavity defined within the body portion; andat least one port in communication with the cavity defined in the body portion, the at least one port configured to receive a fluid into the cavity and discharge the fluid from the cavity, wherein the resilient expandable pressure vessel has a predetermined expansibility across a range of operating pressures of the fluid in the cavity, the range being at least 200 psi,wherein the resilient expandable pressure vessel has a volumetric expansion greater than approximately 0.1% when an operating pressure of the fluid in the cavity is approximately 500 psi, andwherein the resilient expandable pressure vessel has an expansion less than approximately 200% when an operating pressure of the fluid in the cavity is greater than approximately 5000 psi. 2. The resilient expandable pressure vessel of claim 1, wherein the predetermined expansibility of the resilient expandable pressure vessel varies across the range of operating pressures of the fluid in the cavity. 3. An accumulator comprising the resilient expandable pressure vessel of claim 1. 4. A suspension system, comprising: a cylinder defining a chamber;at least one of a piston and a rod reciprocally movable within the chamber;a resilient expandable pressure vessel defining a cavity in communication with the chamber; anda fluid contained within the chamber and the cavity, wherein the resilient expandable pressure vessel has a predetermined expansibility across a range of operating pressures of the fluid in the suspension system, the range being at least 200 psi, andwherein the resilient expandable pressure vessel has a volumetric expansion greater than approximately 0.1% when an operating pressure of the fluid in the resilient expandable pressure vessel is approximately 500 psi. 5. The suspension system of claim 4, wherein the resilient expandable pressure vessel has an expansion less than approximately 200% when an operating pressure of the fluid in the resilient expandable pressure vessel is greater than approximately 5000 psi. 6. The suspension system of claim 4, wherein the fluid is a liquid. 7. The suspension system of claim 6, wherein the liquid is a compressible liquid. 8. The suspension system of claim 6, wherein the liquid is a non-compressible liquid. 9. The suspension system of claim 4, wherein the resilient expandable pressure vessel surrounds the cylinder. 10. The suspension system of claim 9, wherein the cylinder defines at least one orifice placing the chamber directly in communication with the cavity. 11. The suspension system of claim 9, further comprising a manifold and valve assembly coupled to the cylinder, wherein the manifold and valve assembly is selectively operable between an open position in which the chamber is in communication with the cavity and a closed position in which the chamber is isolated from the cavity. 12. The suspension system of claim 4, wherein the resilient expandable vessel is separated from the cylinder. 13. The suspension system of claim 4, further comprising a valve located between the chamber and the resilient expandable pressure vessel, wherein the valve is selectively operable between an open position in which the chamber is in communication with the cavity and a closed position in which the chamber is isolated from the cavity. 14. The suspension system of claim 4, further comprising a second resilient expandable pressure vessel defining a second cavity in communication with the chamber. 15. The suspension system of claim 14, further comprising a valve located between the chamber and the second resilient expandable pressure vessel, wherein the valve is selectively operable between an open position in which the chamber is in communication with the second cavity and a closed position in which the chamber is isolated from the second cavity. 16. The suspension system of claim 4, wherein the expansibility of the resilient expandable pressure vessel varies across the range of operating pressures of the fluid in the cavity. 17. The suspension system of claim 16, wherein the predetermined expansibility of the resilient expandable pressure vessel comprises a first region having a first rate of expansion and a second region having a second rate of expansion less than the first rate of expansion, and wherein a transition point between the first region and the second region occurs before the at least one of the piston and the rod reaches a fully compressed position in the cylinder such that the resilient expandable pressure vessel functions as a jounce bumper.
