초록 ▼

A magnetotrictive peristaltic pump transfers a fluid from a supply chamber o a receiving chamber. The pump has a housing and a core section mounted within the housing. The core section is fabricated from a magnetostrictive material such as Terfenol-D, which can be made to expand directionally in the presence of a magnetic field. There is a fluid tight seal between the inner surface of the housing and the outer surface of the core section. Wrapped around the outer surface of the housing are a plurality of electrical coils. The positive terminal and the negative terminal of each coil are connected to a signal generator which generates direct current electrical signals to sequentially energize each coil. Energizing any one of the coils creates a magnetic field in the general area of the coil. In the presence of this magnetic field, the core section expands longitudinally resulting in lateral/radial shrinkage of the core section which creates a cavity in the general area of the magnetic field. The signal generator sequentially energizes the coils to move the cavity and the fluid contained therein from the supply chamber to the receiving chamber.

[ What is claimed is:] [1.] A magnetostrictive peristaltic pump for transferring a liquid from a supply chamber to a receiving chamber comprising:a housing coupled to said supply chamber and said receiving chamber, said housing having an inner surface and an outer surface;a core section mounted in said housing, said core section having an outer surface which is flush with the inner surface of said housing to form a seal between the outer surface of said core section and the inner surface of said housing;said core section comprising a magnetostrictive material which extends the length of said housing to communicate with said supply chamber and said receiving chamber;a plurality of equally spaced apart electrical coils wrapped around the outer surface of said housing from one end of said housing to the other end of said housing;signal generator means for producing a plurality of electrical signals and sequentially providing one of said electrical signals to each of said plurality of electrical coils, said plurality of electrical coils being sequentially energized by said electrical signals to form a moving cavity within said core section, said moving cavity being formed adjacent the inner wall of said housing; andsaid moving cavity, responsive to said electrical coils being sequentially energized by said electrical signals, traveling longitudinally from said supply chamber to said receiving chamber to extract said fluid from said supply chamber and supply said fluid to said receiving chamber.
