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.

Claim (Index 26):
A nozzle head for a spray pump, preferably finger-actuated spray pump, comprising a pump head, a receiving pin in the pump head, and a cap having a spray nozzle being catch-mounted in the pump head in association with the receiving pin, wherein the receiving pin has a longitudinal axis extending in the mounting direction of the cap, and a liquid path in the direction of the longitudinal axis is embodied in the receiving pin, which liquid path leads to a central chamber positioned upstream of the spray nozzle, wherein the central chamber further has inlet channels, which extend in a plane running perpendicular to the longitudinal axis and which are partly formed by an inner surface of the cap and partly by an outer surface of the receiving pin, wherein further the boundary surfaces of the inlet channels, with the exception of a bottom surface, are only embodied in the cap and wherein the receiving pin has a closed planar front face, which is simultaneously used to form the boundary surfaces of the inlet channels, wherein the front face is surrounded by a circumferential surface, which runs in a stepped manner with regard to said front face and which extends at least across the circumferential angle, in which the inlet channels are spaced apart, wherein the inlet channels radially outwards lead into an annular channel, which is created as a result of the circumferential surface, wherein a side wall of an inlet channel is built by a rib formed in the cap and wherein the running through rib in circumferential direction and seen with reference to a longitudinal axis builds the inner side wall as well as the outer side wall of each inlet channel and moreover a radial outer connection wall between the outer side wall and the inner side wall of each inlet channel.
