Abstract
A finger spray pump for spraying a medium has a finger-actuated pump head movable between a spraying position and an initial position. The pump has an outlet nozzle and a pump chamber with an inlet valve and an outlet valve, a piston rod, a pump piston, a first spring acting between the piston rod and the pump piston, and a second spring acting between the piston rod and the pump housing. The pump piston is movable between a sealed position and an open position, to form the outlet valve, wherein the pump piston in the sealed position lies on a sealing extension of the piston rod and in the open position allows the passage of medium between the sealing extension and the pump piston. The pump piston is supported on two zones of an outer surface of the piston rod that are axially spaced apart.
