DETAILED DESCRIPTION OF THE PREFERRED EMBQDIMENTS
Please refer to Fig. l . The pump unit for magnet~ally driving sn article of the present invention includes a main body 11, an article 12 and a coil 13.
The main body 11 can be a tubular body having a certain length and an internal chamber The article 12 has a certain length and a configuration corresponding to the shape of the chamber. The article 12 is reciprocally movably positioned in the chamber. The article 12 can be a magnet or a superconductor subject to the action of magnetic force.
The mil 13 is wound around the main body 11 and connected with a circuit.
The circuit provides a current such as an alternate current or a periodically alternate current for the coil 13 so as to drive the article 12 to move or reciprocally move for pushing a fluid on one side or two sides of the article 12.
In addition, at least an outer circumference of the main body is dispo~d with or formed of a magnetically conductive material such as silicon steel, iron, amorphous material (such as amorphous Si), permanent magnet and superconductor. The main body 11 can be formed of a sheet body spirally continuously wound into a circular tubular body. Alternatively, the main body i1 can be composed of multiple circular sleeves having different diameters and fitted with each other.
Referring to Fig. 2, another structure of the main body 11 includes a circular tubular body 111 having a chamber and a magnetic conductor 112 enclosing the circular tubular body 111. The magnetic conductor 112 can be made of silicon steel, iron, amorphous material, permanent magnet or superconductor. The magnetic conductor 112 can be formed of a sheet body spirally continuously wound around the circular tubular body 111. Alternatively, the magnetic conductor 112 can be composed of multiple circular sleeves with different diameters. The sleeves are fitted around the circular tubular body 111 and fitted with each other.
The above structure serves as a power source for a reciprocating pump. The coil 13 is wound around the magnetically conductive material or the magnetic conductor 112 to achieve better magnetic faux for acting on the article 12.
Such design is also for lowering the temperature of the coil 13.
Again referring to Fig. 2, the present invention further includes a magnetic path section 14 enclosing the coil 13. The main body 11 has two open ends. The magnetic path section 14 can be made of metal material for eifeckively conducting the magnetic field generated by the coil 13 to drive the article 12. Two ends of the magnetic path section 14 are bent and extend through two ends of the main body into the main body by a certain depth. Alternatively, the two ends of the magnetic path section 14 are bridged with another magnetic path section extending to two ends of the main body 11. Accordingly, the magnetic field can be more effectively conducted and another magnetic field can be generated to act on the article 12. In the case that the main body 11 includes a magnetically conductive material, the extending portion of the magnetic path section 14 or the bridged portion of the magnetic path section 14 will not contact with the magnetically conductive material of the main body 11 so as to avoid unexpected magnetic path. This is for achieving better electromagnetic effect.
Referring to Figs. 1 and 2, the present invention further includes at least one restricting section 15 disposed in the chamber on one side of the article 12.
The restricting section 15 serves to restrict the travel of one end of the article 12, whereby a greater electromagnetic farce is applied to the article 12 in a predetermined position. This is because in a certain position, a greater composite magnetic force is achievable.
Referring to Figs. t and 2, the chamber communicates with two open ends of the main body 11. The present invention further includes a first pair of one-way valve sections 16 and a second pair of one-way valve sections 18. The first and second pairs of one-way valve sections 16 are respectively disposed at two ends ~of the main body 11, whereby the fluid can only flow from a first position to a second position. Ac~rdingly, the present invention can transfer the fluid by means of reciprocating the article 12.
Referring to Figs. 3, 4 and 5, the first and second positions are outside the pump unit. One of the first pair of one-way valve sections 16 on one side of the article 12 and one of the second pair of one-way vahre sections 16 on the other side of the article 12 communicate with the first position. The remaining two one-way valve sections 16 communicate with the second position. The present invention further includes an enclosing member 17 enclosing the coil 13 and the four one-way valve sections 16. A first flow way 171 is formed in the first position for communicating with the one-way valve sections 18 in the first position. A
second flow way 172 is formed in the second position for communicating with the one-way valve sections 16 in the second position. Two rends of the enclosing member 17 respectively serve as an inlet and an outlet of the fluid. In other words, the fluid can sequentially flow through the first flow way 171, the chamber and the second flow way 172.
In the pump unit of the present invention, each one-way valve section 16 has a third flow way fit and a valve 84. The third flow way 62 has a middle section and two ends. The middle section has a cross-sectional area. larger than a cross-sectional area of the two ends of the third flow way B2. A stopper section 66 is further disposed in the middle section of the third flow way 62.
The valve fi~ is movably disposed in the middle section of the third flow way 62 and positioned between the stopper section 66 and one end of the third fbw way 62. The valve 64 has ~t cross-sectional area smaller than that of the middle section of the third flow way 62, while being larger than that of the ends of the third:flow way fit. When the valve 64 moves to the stopper section 66, the valve 84 will not hinder the ftuid from flowing through the third flaw way 62. Reversely, when the valve 62 moves away Pram the stapper section 66, the valve fi4 will block the third flow way 62 to prevent the fluid fram flowing through the third flow way B2.
The pump unit of the present inventian can further include another coil extending in a direction in which the article 12 moves. The other coil is adjacent to the coil 13 and wound around the main body 11. The two coils can be respectively independently connected to two circuits. Alternatively, the coils can be interconnected and then connected fio a circuit. The two coils can provide magnetic lines in diffier~ent directions to more effecctively act on and drive the article 12.
According to the above arrangement, the pump unit of the present invention has the following advantages:
1. The power section, transmission section and pumping section of the conventional pump are integrated to min'rfy the volume of the pump.

78. The pump unit as claimed in claim 70, further comprising another coil extending in a direction in which the article moves, the other colt being adjacent to the coil and wound around the main body, the two coils serving to provide magnetic lines in different directions.
79. The pump unit as claimed in claim 71, further comprising another coil extending in a direction in which the article moves, the other coil being adjacent to the coil and wound around the main body, the two coils serving to provide magnetic lines in different directions.
80. The pump unit as claimed in claim 72, further comprising another tail extending in a direction in which the article moves, the other coil being adjacent to the coil and wound around the main body, the two coils serving to provide magnetic lines in different directions.
81. The pump unit as claimed in claim 73, further comprising another coil extending in a direction in which the article moves, the other coil being adjacent to the coil and wound around the main body, the two coils serving to provide magnetic tines in different directions.
82. The pump unit as claimed in claim 74, further comprising another coil extending in a direction in which the artiste moves, the other coil being adjacent to the colt and wound around the main body, the two soils serving to provide magnetic lines in different directions.
83. The pump unit as claimed in claim 75, further comprising another coil extending in a direction in which the article moves, the other coil being adjacent to the coif and wound around the main body, the two coils serving to provide magnetic lines in different directions.
84. The pump unit as claimed in claim 76, further comprising another coil extending in a direction in which the article moves, the other coil being adjacent to the coil and wound around the main body, the two coils serving to provide magnetic lines in different directions.
