RECIPROCATING PUMP ASSEMBLY FOR LIQUIDS
First Claim
1. A reciprocating pump assembly (1) for dispensing liquids,the pump assembly comprising:
- a pump housing (2) providing an interior compartment, the pump housing being provided with an inlet (3) through which a liquid to be dispensed is provided, and an outlet (4) for dispensing the liquid,a piston (5) being arranged to perform a linear movement within the interior compartment of the pump housing, the piston comprising ferromagnetic material,a magnetic actuator for generating a magnetic field acting on the piston,characterized in that;
the magnetic actuator comprises a permanent magnet (6) arranged to be moved linearly substantially parallel to the linear movement of the piston (5), whereby a linearly moving magnetic field is generated, such that the piston can be moved within the pump housing between a resting position and an actuated position under influence of the linearly moving magnetic field.

Abstract
A reciprocating pump assembly for dispensing liquids is provided. The pump assembly comprises a pump housing providing an interior compartment and being provided with an inlet for providing a liquid to be dispensed, and an outlet for dispensing the liquid. The assembly further comprises a piston being movably mounted within the interior compartment of the pump housing and comprising ferromagnetic material. The assembly comprises a magnetic actuator for generating a linearly moving magnetic field acting on the piston. The magnetic actuator comprises a permanent magnet arranged to be moved in linear directions, whereby the piston is moved in the pump housing between a resting position and an actuated position under influence of the linearly moving magnetic field.
