Magnetic system for isolated chamber pumps

Abstract

Vibrating liquid pump with an electromagnetic system comprising a coil ( 1 ); a metallic frame consisting on a “U” shaped piece ( 2 ) and a lower plate closure ( 3 ) which are placed around the coil ( 1 ) and the bushings ( 7 ); the screw stud ( 4 ) is responsible for bonding and fixing the set trough the driver chamber ( 5 ), where the magnetic core ( 6 ) moves longitudinally and in alternate direction. The screw stud ( 4 ) of the magnetic system join the components ( 2, 3, 7, 5 ) in a single assembly operation and is arranged behind and axially aligned the magnetic core ( 6 ) to optimize the attractive force and reduce the amount of copper required in the coil ( 1 ).

1 . Vibrating pump for liquids applicable in the displacement of fluids, comprising a compression chamber ( 12 ) provided with an inlet ( 17 ) and an outlet ( 18 ) for the liquid; an electromagnetic system comprising a coil ( 1 ) a metallic frame consisting on a “U” shaped piece ( 2 ) and a lower plate closure ( 3 ) which are placed around the coil ( 1 ) which contain the bushings ( 7 ) and the a screw stud ( 4 ) responsible for bonding and fixing the assembly trough the driver chamber ( 5 ); a pumping means comprising a magnetic core ( 6 ) extending in a plunger ( 9 ) into the compression chamber ( 12 ) which moves longitudinally and in alternate direction inside the drive chamber ( 5 ) thanks to the alternative attraction force of the electromagnet and the compression spring ( 19 ); characterized in that: the screw stud ( 4 ) bonding and fixing the set is disposed behind the magnetic core ( 6 ) and axially aligned therewith to optimize the attractive force and to reduce the amount of copper required in the coil ( 1 ). 
     
     
         2 . Vibrating pump according to  claim 1 , characterised because the pumping means are constituted by a compression spring ( 19 ) and a magnetic core ( 8 ) extending in a plunger ( 9 ) fixedly but with freedom of axial deflection due to the patella ( 10 ) and the semi-housing ( 11 ) which house the said plunger inside the magnetic core ( 8 ). 
     
     
         3 . Vibrating pump according to  claim 1 , characterised because the compression chamber ( 12 ) is inserted into the driver chamber ( 5 ) and fixed by the fork ( 13 ) that holds the compression chamber ( 12 ) joined to the said drive chamber ( 5 ) and free to rotate 360° on its axis; a sealing means ( 14 ) and a washer ( 15 ) prevents the liquid to leak to the magnetic system and the seal ( 16 ) holds the assembly under tension to prevent leakage and noise.
