Fluid discharge head

摘要

Fluid discharge head having a discharge nozzle which can be placed on a discharge device and which holds a medium guide and a medium outlet at the end of a medium guide, in the region of the medium outlet a movable closure element that can be moved into an open position is provided and, for the purpose of actuating discharge, the discharge nozzle and the discharge device can be moved axially towards each other, for which purpose the discharge nozzle has a skirt to form a sliding guide with a section on the discharge device, the skirt (9) of the discharge nozzle (5) being assigned a second, additional skirt (12) in order to form an annular bush (13) which can be mounted such that it can be displaced longitudinally on a section (11) of the discharge device (2) that is formed as an annular shaft.

主权项

1. 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; andan 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; andwherein 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.
