Abstract:
A thrust piston pump for an active substance dispenser has two equiaxial, position-rigid, interconnected pistons running in the same direction, namely a pump piston passing in and out of an otherwise closed pump chamber and a larger presuction pistion located downstream thereof, in whose associated pressure chamber is located the pump chamber end opened by the passing out of the pump piston. This leads to a very accurate dosing of the discharged active substance quantity, accompanied by a simple construction and high operational reliability.
