1. Field of the Invention
The present invention relates to a pump and in particular to a minimized high pressure pump.
2. Description of the Related Art
Conventional minimized pumps thus are often unable to provide high energy, high thrust, and high pressure at the same time.
SUMMARY OF THE INVENTIONAn object of the present invention is to provide a pump that solves the above mentioned problems.
The pump of the present invention comprises a housing, a conductor, a first coil and a second coil. The housing has an intake and an output. The conductor is movably disposed in the housing. The first coil generates a magnetic force to attract the conductor toward the output when electrified, such that fluid between the conductor and the output flows out of the housing. The second coil generates a magnetic force to attract the conductor toward the intake when electrified, such that fluid between the intake and the conductor flows between the conductor and the output.
Fluid is taken into the housing and store between the intake and the conductor when the first coil is electrified.
The pump further comprises a first base and a second base, both disposed in the housing. The first coil is wound around the first base and the second coil is wound around the second base. The first and second bases may be electrically insulated.
The pump further comprises entrance and exit valves. The entrance valve is disposed between the intake and conductor, and the exit valve between the conductor and the output. The entrance valve opens and the exit valve closes when the first coil is electrified, and the entrance valve closes and the exit valve opens when the second coil is electrified.
The entrance valve and the exit valve are one-way valves.
The one-way valve mentioned comprises an elastic member, with a ball and barricade connected to the elastic member and the ball disposed therebetween.
An end of the elastic member connects to the conductor, and another end is disposed between the first and second bases.
The elastic member comprises a corrugated portion near the first base's connection to the second base.
The elastic member connects to the second base.
The elastic member may be of rubber, the ball of a steel, and the barricade an aluminum plate with openings.
The housing may be of permeable material, and the pump may further comprise a conducting plate disposed in the housing. The conducting plate may be disposed between the first and second bases.
DESCRIPTION OF THE DRAWINGSThe present invention can be more fully understood by reading the subsequent detailed description in conjunction with the examples and references made to the accompanying drawings, wherein:
The housing 21 has a first base 25 and a second base 26. The first coil 23 is wound around the first base 25. The second coil 24 is wound around the second base 26. The first base 25 and the second base 26 are electrically insulated, constructed of insulating material.
The housing 21 has an exit valve 27 and an entrance valve 28. The exit valve 27 is disposed between the output 211 and the conductor 22. The entrance valve 28 is disposed between the intake 212 and the conductor 22.
The exit valve 27 and the entrance valve 28 are both one-way valves. As shown in
Entrance valve 28 is also a one-way valve. As shown in
Elastic members 271 and 281 are of rubber, balls 272 and 282 are of steel, and barricades 273 and 283 are aluminum plates with openings.
Furthermore, the housing 21 is of permeable material, and a conducting plate 29 is disposed in the housing 21. In particular, the conducting plate 29 is disposed between the first base 25 and the second base 26, acting as a circuit therebetween.
As mentioned above, the pump of the present invention can be treated as two sets of concentric solenoids series connected to form the pump. The housing 21, the first coil 23 and the first base 25 form the first solenoid, and the housing 21, the second coil 24 and the second base 26 form the second solenoid. The conducting plate 29 provides a circuit between the two solenoids. The conductor 22 is the conducting cylindrical piston driven by the two solenoids, both of which repeatedly attract the conductor 22 to provide significant force in both directions. Control of the activity of the two solenoids controls the pump action.
Referring to
Referring to
The procedure disclosed is repeated, that is, the first coil 23 and the second coil 24 are electrified in turn to move the conductor 22 repeatedly in the housing 21, continuing fluid transfer.
Note that one end of elastic member 271 of the exit valve 27 seals the gap between the first base 25 and the second base 26, while the other end is connected to the conductor 22. Thereby, fluid in the housing 22 does not leak through the gap. In other words, fluid flowing both into the housing 22 and out of the housing 22 is controlled along the directions of arrow A or arrow B, passing through entrance valve 28 or exit valve 27 thereby.
Elastic member 271 of the exit valve 27 has a corrugated portion which can expand and contact to conform to conductor 22 during motion.
Accordingly, the advantage of the present invention is the solenoid allowing minimization of the pump, while providing maximum compression energy at the same time. The present invention may utilize at dissipating system in a notebook or a server, variety of minimized compressor and medical equipment.
Finally, while the invention has been described by way of example and in terms of the preferred embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover various modifications and similar arrangements as would be apparent to those skilled in the art. Therefore, the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements.
