Definitions

the invention relates to a discharge head or a discharge device for flowable media, in particular liquids.
this discharge head can have a discharge opening or nozzle and a connecting member for connection to a counterpart, e.g. form a valve tappet, a pump piston or the like. of the discharge device, wherein it is preferably provided with an inserted inner body which extends approximately into the region of the discharge nozzle. This enables a simple structure and high strength to be achieved.
the invention is further based on the object of avoiding disadvantages of known solutions and, in particular, of creating a discharge head in which the operating forces which occur can be transmitted safely and directly.
the inner body can at least partially establish a direct connection to the counterpart, which it touches or on which it can be supported, so that essentially the entire actuating pressure is transmitted to the counterpart via the inner body and dead spaces can be reduced .
the connecting element is essentially formed by a component separate from the base body and firmly connected to the inner body, and is essentially freely located in the base body in such a way that it is not immediately closely encased by it, but at most at a radial distance.
the connecting member or the inner body can be supported directly on the base body with at least one end face or shoulder surface.
the other end of the inner body can also form a functional part of the discharge nozzle, namely in particular an inner nozzle core which is overlapped by a cap-shaped nozzle body and having the nozzle opening.
This nozzle body is expediently formed in one piece with the base body.
the design according to the invention is particularly suitable for such discharge devices in which the pump piston has an axially compressible piston sleeve to form an outlet valve, which surrounds a piston core forming a valve seat and is axially supported with its end remote from the piston relative to this piston core.
a one-piece pump piston with a shaft attachment on the connecting member or to form the pump piston in one piece with the connecting member or to provide no valve.
the one at that Connecting portion of the inner body can limit, for part or all of its length, an outlet channel located in it and / or an outlet channel located on its outer circumference as a connection between the pumping chamber or the outlet valve and the discharge nozzle.
the outlet channel also passes through the connecting member or the pump piston.
the inner body has longitudinal sections of different outer widths, which expediently decrease in the direction of the discharge nozzle.
a dead volume between the counterpart of the discharge device and the adjoining section of the outlet channel can also be avoided by the described configuration, the directly adjoining channel sections of the counterpart and the inner body expediently having approximately equal flow cross sections.
the inner body is advantageously accommodated in the base body with a radial press, the clamping force of which is greater than the radial pressure of a maximum operating pressure in the discharge channel. If the discharge channel lies completely within the inner body over a first part of its length and only on a subsequent, mechanically stiffer longitudinal section on the outer circumference, this configuration can be achieved relatively easily. This pressure prevents the discharge channel, although limited by two separate parts, from being elastically expanded or leaking under the operating pressure.
the discharge head 1 which is composed essentially of only two components, has a base body 2 which forms a cap 3 at one end and with its end wall a handle 4, over the other end surface of which a nozzle 5 projects.
This is essentially formed by an outer sleeve 6 directly adjoining the handle 4 and an inner sleeve 7 lying essentially without contact therein, which with its end remote from the cap 3 merges in one piece into the outer sleeve 6.
the connecting piece 5 forms a one-piece nozzle cap 8 with a nozzle bore 9 lying in the end wall, to which a swirl device 11 is directly assigned on the inside of the end wall. All components lie essentially in a central axis 10.
An essentially rod-shaped or shaft-shaped inner body 12 is inserted into the inner sleeve 7 of the base body 2 only by inserting its shaft 13, which has essentially smooth outer surfaces.
the shaft 13 forms an adjoining a connecting member 16, cylindrical shaft section 14, which merges via a frustoconical shoulder and contact-free with respect to the inner sleeve 7 into a cylindrical shaft section 15 of smaller diameter, which extends with its end face to the inner surface of the end wall of the nozzle cap 8 and can be provided with profiles to form the swirl device 11.
the connecting member 16 is completely free and immediately afterwards at the free end of the inner sleeve 7, by means of which it protrudes over the entire length and with respect to the outer sleeve 6 without contact into the cap 3, but is set back relative to the end of the cap.
the connecting member 16 serves as the only component for connecting the discharge head 1 to a discharge device which e.g. has a pump inserted into a container neck in a sealed manner for sucking medium from the container and for pushing this medium out through the nozzle 9 at each pump stroke.
the counterpart 17 has a shaft part 18 adapted to the connecting member 16 and corresponding to its inner length, the outer width of which approximately corresponds to that of the shaft 13.
the counterpart carries at its end remote from the shaft part 18 a pump piston 19 which is essentially formed by a piston sleeve 20 with a compressible neck and an enlarged piston lip and a piston core 21 which passes through the piston sleeve 20.
the piston core has a core shaft 22 directed against the connecting member 16, which has essentially the same outside width as the shaft part 18.
the piston core 21 could be formed in one piece with the shaft part 18 or form it and therefore be inserted directly into the connecting member 16, in which case the cuff neck would be axially supported at the end of the connecting member 16.
the shaft part 18 is formed by an intermediate piece 23, in the extended, in the outer width corresponding to the connecting member 16 socket part of the core shaft 22 is inserted by insertion so that the cuff neck is supported at the end of this socket part.
the inner circumference of the piston sleeve 20 forms with the outer circumference of the piston core 21 an outlet valve 24, which opens under a certain pressure in the pumping chamber of the pump 25 or by axially abutting the piston lip and compressing the collar of the neck into a channel section 27 which extends between the outer circumference of the core shaft 22 and the inner circumference of the piston sleeve 20 or the intermediate piece 23.
the channel section 27 adjoins a channel section 28 lying in the manner of a bore within the shaft part 18.
the channel sections 27, 28 belong to an outlet channel 29 which extends from the outlet valve 24 to the swirl device 11 or nozzle 9.
the shaft section 14 forms a channel section 30 which lies completely within its outer circumference and extends from the inside of the connecting member 16 and which, adjacent to the transition section between the shaft sections 14, 15, opens radially outward into a channel section 31 which is located between the outer circumference of the shaft section 15 and the inner circumference of the inner sleeve 7.
the channel section 31 formed, for example, by a longitudinal groove in the shaft section 15, which has substantially smaller passage cross sections than the channel section 30, extends as far as the swirl device 11.
the shaft sections 14, 15 engage in bore sections of a correspondingly graduated bore of the inner sleeve 7 which are adapted to them.
the essentially cup-shaped connecting member 16 has a jacket or a sleeve 32 which has approximately the same outer width as the inner sleeve 7 and connects to the latter within the outer sleeve 6 approximately without gaps.
the free end of the inner sleeve 7 is set back correspondingly with respect to the associated end of the outer sleeve 6 or the end wall of the cap 3.
the cuff 32 delimits an essentially cylindrical plug-in opening 33, from the flat bottom of which the channel section 30 extends and on the bottom of which the shaft part 18 lies in the inserted state, so that the channel section 28 directly adjoins the channel section 30.
the insertion opening 33 has an introducer 35 which is conically widened at an acute angle for the shaft part 18 which is correspondingly tapered at the free end. Between the ends of the cylindrical portion and slightly closer to the introducer 35 than the bottom 34, the insertion opening 33 has at least one slightly inwardly projecting, one-piece annular bead or the like. As a clamping ring and seal for the shaft part 18, so that it is easy to insert, then but is kept safe.
the bottom wall of the connecting member 16 forms an annular shoulder 37 for support on the end face of the inner sleeve 7.
the sleeve part of the intermediate piece 23 can have an annular shoulder for support on the end face of the connecting member 16.
this sleeve part, the collar 32 and the inner sleeve 7 form a common, continuously and essentially continuously continuous outer peripheral surface.
the connecting member 16 can thus move into the pump 25 or its associated cylinder cover until the cap end wall strikes with its inner surface.
the connecting member 16 is significantly shorter than the shaft 13 and several times longer than its outer width.
the shaft section 15 is longer than the shaft section 14.
the plug opening 33 lies completely outside the inner sleeve 7.
