Abstract
The invention relates to a vibrating armature pump having a pump housing, which comprises a cylinder for receiving a substantially linearly displaceable pump piston unit (10). The pump piston unit (10) comprises at least one pump element (11) for pumping the pumping fluid and a drive element (12) for driving the pump element (11). Both elements are designed separately and arranged loosely one behind the other.
Claims9
A vibrating armature pump with a pump casing (2), which comprises a cylinder (13) for receiving a pump piston unit (10) adjustable essentially linearly, characterized in that the pump piston unit (10) has at least one separate pump element (11) for pumping the pump fluid and one separate drive element (12) for driving the pump element (11).
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least one first spring element (28) is provided for acting with force upon the pump piston unit (10) and/or the pump element (11).
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least one second spring element (31) is provided for acting with force upon the pump piston unit (10) and/or the drive element (12), the spring force of the second spring element (31) being directed opposite to the spring force of the first spring element (28).
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least the drive element (12) is composed essentially of a ferromagnetic material.
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least the drive element (12) is composed essentially of high-grade steel.
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least the pump element (11) is composed essentially of a plastic.
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that at least one coil (4) is provided for adjusting the drive element (12).
The vibrating armature pump as claimed in one of the abovementioned claims, characterized in that a pulsating or intermittent voltage is provided.
