Variable length shaft and method for making the same

A variable length shaft is provided including a housing defining an internal space. A shaft is connected to a plunger device disposed in said internal space. The internal space is filled with magneto-rheological fluid which is selectively provided with a magnetic field for solidifying the fluid to p...

Beschreibung
Zusammenfassung:	A variable length shaft is provided including a housing defining an internal space. A shaft is connected to a plunger device disposed in said internal space. The internal space is filled with magneto-rheological fluid which is selectively provided with a magnetic field for solidifying the fluid to prevent movement of the plunger within the internal space. When the magnetic field is removed, the plunger device moves freely for allowing variation in the length of the variable length shaft system.
