A fluid delivery device, in particular for delivering exhaust gas posttreatment media, such as a urea-water solution, for an internal combustion engine, includes a movable work wall, in particular a work diaphragm. A work chamber is provided for a fluid that is to be delivered via at least one fluid connection. The work chamber is capable of being increased and decreased in size by means of the movable work wall, the at least one fluid connection, and at least one mechanism for moving the work wall upon an intake stroke and a compression stroke. The at least one mechanism is embodied such that the force for moving the work wall both in the intake stroke and in the compression stroke includes a Lorentz force.
