    Abstract: A fluid pump has a pump body and a displacer, the displacer and the pump body being implemented such that a pump chamber is defined therebetween, the pump chamber having an inlet opening and an outlet opening, neither the inlet opening nor the outlet opening being provided with a check valve. A drive means is provided which positions the displacer periodically at a first and at a second end position. The displacer closes the outlet opening when it occupies its first end position and leaves the outlet opening free when it occupies its second end position and leaves the inlet opening free at both end positions thereof. The displacer, when moving from the first to the second end position, defines a flow-through gap which opens between the displacer and the pump body in the area of the outlet opening in dependence upon the movement, the flow-through gap being defined such that the flow through the outlet opening depends on the pressure in the pump chamber as well as on the respective opening degree of the flow-through gap.

    Abstract: A microdosing device comprises a pressure chamber which is at least partly delimited by a displacer, an actuating device for actuating the displacer, the volume of the pressure chamber being adapted to be changed by actuating the displacer, a media reservoir which is in fluid comunication with the pressure chamber via a first fluid line, and an outlet opening which is in fluid communication with the pressure chamber via a second fluid line. The microdosing device additionally comprises a means for detecting the respective position of the displacer and a control means which is connected to the actuating device and to the means for detecting the position of the displacer, said control means controlling the actuating device on the basis of the detected position of the displacer or on the basis of displacer positions detected during at least one preceding dosing cycle so as to cause the discharge of a defined volume of fluid from the outlet opening. The control means comprises means for controlling the actuating device with a signal of low edge steepness so as to cause the displacer to move from a first position to a predetermined second position, the second position of the displacer defining a larger volume of the pressure chamber than the first position. In addition, the control means comprises means for controlling the actuating device with a signal of high edge steepness so as to cause the displacer to move from the second position to the first position for discharging in this way a defined volume of fluid from the outlet opening.
