A regeneration method for a hydraulic system enables the fluid being forced from a first actuator to be used to power a second actuator. Often the force of the load acting on a hydraulic actuator is used to move the actuator into a given position which motion forces fluid from the actuator. Rather than simply draining that fluid to the system tank, the fluid is routed to a second actuator to be powered when the pressure of the fluid draining at the first actuator is greater than the pressure required to power the second actuator. At other times the draining fluid can be used to drive the pump which has been configured to operate as a motor thereby driving the prime mover connected to the pump. Alternatively the draining fluid can be routed to an accumulator where it is stored under pressure until needed to power an actuator of the system. A unique bidirectional pilot operated poppet valve.

An expanded graphite knitting yarn according to claim 1, wherein the reinforcing material is selected and used from among metallic line members such as stainless steel, Inconel, and monel metal; organic fibers such as a cotton fiber, a rayon fiber, a phenol fiber, an aramid fiber, a PBI fiber, a PBO fiber, a PPS fiber, and a PEEK fiber; or inorganic fibers such as a glass fiber, a carbon fiber, and a ceramic fiber. 3. An expanded graphite knitting yarn according to claim 1, wherein reinforcing fibers are embedded in the expanded graphite tape in a longitudinal direction of the tape. 4. An expanded graphite knitting yarn according to claim 3, wherein, as the reinforcing fibers, any one selected from organic fibers such as a cotton fiber, a rayon fiber, a phenol fiber, an aramid fiber, a PBI fiber, a PBO fiber, a PPS fiber, and a PEEK fiber; any one selected from inorganic fibers such as a glass fiber, a carbon fiber, and a ceramic fiber; or any one selected from metallic line members such as stainless steel, Inconel, and monel metal is used; or at least two materials selected from the organic fibers, the inorganic fibers, and the metallic line members are complex-used. 5. An expanded graphite knitting yarn according to claim 1, wherein expanded graphite particles on a surface of the expanded graphite tape are partially removed. 6. An expanded graphite knitting yarn formed by applying a twisting process to an expanded graphite tape, characterized in that a whole of an outer periphery of the expanded graphite tape including ends thereof, which has been subjected to the twisting process, is bound and covered with a reinforcing material which is knitted or made of a braided body, before the tape is subjected to a braiding process. 7.

An expanded graphite knitting yarn according to claim 6, wherein the reinforcing material binds and covers the expanded graphite, so that the expanded graphite which has been subjected to the twisting process may be deformed so as to reduce the diameter thereof. 9. An expanded graphite knitting yarn according to claim 6, wherein reinforcing fibers are embedded in the expanded graphite tape in a longitudinal direction of the tape. 10. An expanded graphite knitting yarn according to claim 6, wherein expanded graphite particles on a surface of the expanded graphite tape are partially removed. 11. An expanded graphite knitting yarn according to claim 9, wherein, as the reinforcing fibers, any one selected from organic fibers such as a cotton fiber, a rayon fiber, a phenol fiber, an aramid fiber, a PBI fiber, a PBO fiber, a PPS fiber, and a PEEK fiber; any one selected from inorganic fibers such as a glass fiber, a carbon fiber, and a ceramic fiber; or any one selected from metallic line members such as stainless steel, Inconel, and monel metal is used; or at least two materials selected from the organic fibers, the inorganic fibers, and the metallic line members are complex-used. 12. A gland packing made of expanded graphite knitting yarns, characterized in that the plural expanded graphite knitting yarns are put together and subjected to either braiding or twisting process, each expanded graphite knitting yarn being formed by applying a twisting process to an expanded graphite tape, and a whole of an outer periphery of the expanded graphite tape including ends thereof, which has been subjected to the twisting process, being covered with a reinforcing material which is knitted or made of a braided body. 13. A gland packing according to claim 12, whe rein reinforcing fibers are embedded in the expanded graphite tape which forms the expanded graphite knitting yarn, in a longitudinal direction of the tape. 14. A gland packing according to claim 12, wherein expanded graphite particles on a surface of the expanded graphite tape which forms the expanded graphite knitting yarn, are partially removed. 15. A gland packing made of expanded graphite knitting yarns, characterized in that the plural expanded graphite knitting yarns are put together and subjected to either braiding or twisting process, each expanded graphite knitting yarn being formed by applying a twisting process to an expanded graphite tape, and a whole of an outer periphery of the expanded graphite tape including ends thereof, which has been subjected to the twisting process, being bound and covered with a reinforcing material which is knitted or made of a braided body, before the tape is subjected to the braiding process. 16. A gland packing according to claim 15, wherein reinforcing fibers are embedded in the expanded graphite tape which forms the expanded graphite knitting yarn, in a longitudinal direction of the tape. 17. A gland packing according to claim 15, wherein expanded graphite particles on a surface of the expanded graphite tape which forms the expanded graphite knitting yarn, are partially e the turbine airfoils that do not have adequate tip clearance. The tips of those turbine airfoils that do not have adequate tip clearance are then machined to obtain adequate tip clearance. Once all the turbine airfoils have adequate tip clearance, environmental coatings and/or thermal barrier coatings are applied to the blade tips.
