Abstract
The invention concerns a device to convey and/or spray free-flowing media, in particular fluids, which works in accordance with the energy storage principle and is designed as an electromagnetically-powered reciprocating pump with at least one armature device as a drive element, whereby the armature device includes at least two armature elements and the armature elements are assigned magnetically corresponding yoke elements.
Claims66
A device to deliver a free-flowing medium, comprising:
- a drive housing defining a delivery direction of the free-flowing medium;
- a magnet coil disposed within the drive housing, the magnetic coil being constructed to generate a magnetic flux in an energized state;
- an axially movable armature device disposed within the magnet coil, the axially movable armature device comprising at least first and second armature elements, the armature elements being disposed a predetermined distance from one another in the delivery direction, the armature elements defining first and second faces;
- and
- an armature cylinder disposed within the magnet coil adjacent to the armature elements, the armature cylinder comprising at least first and second elements constructed to interrupt the magnetic flux,
- wherein the first and second flux-interrupting elements are disposed adjacent to first and second lands, and
- wherein the first and second lands are disposed first and second predetermined distances from the first and second faces of the armature elements to establish first and second gaps that interrupt magnetic flux, thereby establishing the magnetic flux at least within the armature cylinder, the armature elements, and the drive housing.
