摘要:
A valve includes a case comprising a pin bore, a pin configured to move axially in the pin bore, wherein the pin seals the pin bore, a first channel in communication with the pin bore, a second channel in communication with the pin bore, wherein the second channel comprises a restrictor at a location offset from the first channel, a third channel in communication with the pin bore, wherein the third channel comprises a check valve, and the second channel and third channel are in communication with each other. The valve can be a miniature valve that is used in the control of hydraulic fluid in prosthesis, such as a prosthetic ankle joint.
