  • Dosing pump with linear motor
    Patent number: 11592324
    Abstract: The invention concerns a dosing pump for moving a fluid, comprising a dosing head in which there is a dosing chamber and a displacement element reciprocatable between a first and a second position, wherein the displacement element delimits the dosing chamber, and the volume of the dosing chamber in the first position of the displacement element is greater than the volume of the dosing chamber in the second position of the displacement element, wherein the displacement element is coupled to a linear motor by way of a stroke element in such a way that in operation of the linear motor the stroke element performs a forward stroke and a return stroke in a housing in a direction of a movement axis with a stroke length h and the displacement element is reciprocated between the first position and the second position.
