Patent ID: 8770445

Claim:
A fluid discharge device, comprising: a fluid discharge head, comprising: a discharge nozzle; a discharge opening in one end of the discharge nozzle; a skirt at an opposite end of the discharge nozzle; a cam extending outward from an end of the skirt; an upper valve seat adjacent the discharge opening; an inner sleeve seated in the discharge nozzle and having a pot-shaped end adjacent the upper valve seat; a medium guide through the inner sleeve; a valve body seated in the pot-shaped end of the inner sleeve, comprising: a cylindrical piston; a passage duct through the cylindrical piston in communication with the medium guide; and an intermediate valve plate engaged with the inner sleeve; a pressure chamber defined by the valve body and inner sleeve; a compression spring seated in the pot-shaped end of the inner sleeve and in contact with the valve body, wherein the compression spring holds the valve body against the upper valve seat; a discharge device coupled to the discharge head, comprising: a medium pump attached to the discharge device; a mating piece assembled with the medium pump; a discharge section through the mating piece; a section extending towards the fluid discharge head; a mating cam extending inwardly from an end of the section; and wherein the mating piece is fitted to the fluid discharge head and the discharge section is in communication with the medium guide through the inner sleeve; a push on part attached to the discharge nozzle and having a second skirt extending downward from the discharge nozzle towards the discharge device; and wherein the skirt and the second skirt define an annular bush and the section is positioned in the annular bush between the skirt and the second skirt; and wherein the discharge section, medium guide and passage duct provide a substantially linear pathway through the fluid discharge device.
