Preloaded one-way valve accumulator

摘要

A vibration isolator for connecting a first body and a second body. The vibration isolator includes a housing having a first chamber, a second chamber, and a port connecting the first chamber to the second chamber and permitting fluid to flow between the first chamber and the second chamber. The first and second chambers and the port defining a fluid reservoir. The isolator including a gas-to-fluid accumulator in fluid communication with the fluid reservoir through a first one-way valve and a second one-way valve. The first one-way valve allows fluid to pass only from the fluid reservoir to the accumulator and the second one-way valve allows fluid to pass only from the accumulator to the fluid reservoir. At least one of the first and second one-way valves being preloaded to a predetermined force to permit fluid flow through the at least one-way valve only when fluid pressure exceeds the predetermined force.
