- the assembly has, which expediently has at least one essentially closed pressure or.
- a holder which primarily serves to secure the position of the discharge device and, if necessary, can additionally perform a functional movement for a function of the discharge device.
- a pump piston of an air pump is attached to the housing of a liquid pump, but the air pump and its pump chamber then do not form a self-contained structural unit if a common base body is provided for both the air pump and the media pump.
- FR-A-2 397 341 shows a discharge device with two discharge units which function independently of one another and which are to be connected by plugging together via a holder located outside the pressure spaces of both discharge units.
- US-A-4,179,049 shows a discharge device with two discharge units which are not functional independently of one another, the holder common to both discharge units as a piston only adjoining the pressure space of the one discharge unit.
- DE-A-1 475 153 shows a discharge device, of the two discharge units of which only the air pump is functional in the separated state, the interlocking brackets of the two discharge units lying completely outside the pressure spaces or only adjoining them.
- the invention is also based on the object of avoiding disadvantages of known discharge devices and, in particular, of creating a discharge device which, with the simplest possible construction, ensures simple assembly, high conveying capacity, low space requirements and good adaptation to different further discharge units.
- the features of claim 1 are suitable for achieving this object.
- the holder for connection to the further discharge unit expediently lies at least partially within the pressure space, wherein it is used for holding engagement in a base body and / or in a component of the further discharge unit that can be moved relative to this, for example for the discharge, can be formed.
- the holder is expediently arranged rigidly with respect to the area of the pressure chamber adjoining it and / or with respect to a basic body delimiting it, so that it can form a one-piece component with this basic body, with respect to which another component can be moved manually for discharge actuation. If the discharge device has a plurality of pressure spaces or if it is provided for conveying from different storage spaces for media, two or more holders of the type described can also be provided.
- the holder described has at least part of its axial length in the same longitudinal region as the pressure chamber, as a result of which the construction length of the discharge device can be considerably shortened.
- the particularly annular pressure chamber extends essentially over the entire outer circumference of the holder, which has a radially inner one Form the boundary of this pressure space or can project approximately coaxially freely into the pressure space such that it is accessible from the outside or one end of the pressure space for mounting the further discharge units or the like even when the pressure space is closed and ready for operation.
- the holder does not protrude in the longitudinal or assembly direction or only insignificantly beyond the pressure space, so that it requires practically no additional axial length and can also serve as a piston-like displacement body for the pressure space, which is opposite a radially outer jacket boundary movable component of the discharge device does not need to be sealed, although it can also be guided in the region of the inner circumference of this jacket boundary and thereby secure this component against tilting movements.
- the holder expediently has a mounting opening for inserting the counter member serving to hold the further discharge unit, wherein instead of a threaded opening a pure plug-in opening can be provided, into which the counter-member engages transversely to the plug-in direction essentially free of play and in the plug-in direction with limited stops.
- the holder can also be designed to receive an intermediate piece, which in turn is designed such that the discharge device and / or the further discharge unit can be attached to a base body, e.g. can be attached to the neck of a storage vessel.
- the intermediate piece is expediently cap-shaped as a screw cap, crimp ring or the like, which is frictionally gripped by the holder on the outer circumference with a certain clamping and, with an annular shoulder, tightly clamps the further discharge unit against the end face of the storage neck.
- the insertion opening has a relatively large width when it is formed by the interior of the cap of a cap-shaped holder, the cap end wall can be penetrated by a plunger, which is used for the functional connection with the further discharge unit, but not for its actual position fixing relative to the discharge device.
- the further discharge unit engages in the pressure chamber, essentially as described with reference to the holder, so that in its longitudinal region or that of the holder there is a pressure or pump chamber, a pump piston located in the starting position, an inside the housing or this piston lying exhaust valve, a housing or its cylinder cover and / or an internal return spring can engage or lie completely.
- a support surface of the further discharge unit for support on the storage neck or a fastening cap for fastening the further discharge unit on the storage neck can also lie partially or completely within the pressure space or the holder, so that the further discharge unit engages in this way at least approximately with half of its housing length and the holder or the pressure chamber also receives or engages over the storage neck.
- the pump is at least partially expediently designed as a thrust pump, in particular as a piston and / or bellows pump, with the thrust movement advantageously essentially only the one transverse to the thrust movement adjacent to the holder lying part of the pressure chamber is delimited by a piston raceway or a pump bellows, while a part of the pressure chamber axially adjoining the inner end of the holder communicates with the first-mentioned part without sealing and at most in the area of the passage of a plunger or the like. is slidably sealed by the holder.
- the component which can be moved relative to the base body of the discharge device for discharge actuation can be mounted from the end of the base body which faces away from the mounting end of the holder and which, e.g. is formed by a simple, double-walled ring body, which can be closed at one end in the area of the pressure chamber with a ring-shaped end wall surrounding the holder and in the area of the other end with the cap end wall of the holder, so that at one end there is an annular groove and at the other End of the assembly opening results and both mutually lying jacket walls have approximately the same longitudinal extent.
- a sleeve-shaped piston jacket can then be inserted into the annular groove, which is expediently formed in one piece with an actuating head of the discharge device, which forms an actuating handle and / or carries a discharge opening leading into the open.
- This head can be provided together for actuation or for media discharge both for the discharge device and for the further discharge unit.
- the discharge device is particularly suitable for training as an air pump according to WO 89/00085, to which reference is made for further details and effects.
- the suction for the pump can lie within the holder or its mounting opening, so that an air duct from the outside of the discharge device to an inlet valve is provided essentially exclusively ascending and dirt particles can hardly get into the inlet valve or the pressure chamber.
- the air flow can be between the inner circumference of the mounting shell and the inserted counterpart of the further discharge unit, for example in the form of at least one longitudinal groove.

- This is possible in a particularly simple manner if the two components of the discharge device which can be moved relative to one another are not supported directly against one another via a return spring, but if at least one return spring of the further discharge unit simultaneously serves as a return spring for the movable component of the discharge device.
- the discharge device 1 is used for the load-bearing connection with a further discharge unit 2, which, if e.g. only a pressure charging of the storage space with the discharge device 1 is provided, can be formed directly by a media store 3, to which a base body 4 of the discharge device 1 is also connected in a load-bearing manner.
- This connection can be rigid or e.g. be moveable in the sense that it does not hinder a discharge operation and by such a movement as a rotary movement, e.g. a counter is operated.
- the thin-walled, essentially one-piece base body 4 forms an assembly of the discharge device 1, with respect to which a further assembly 5 having a component 5 can be moved, in particular linearly displaceably, so that a pressure space 6 enclosed between the base body 4 and the component 5 is narrowed .

- the inner width of the outer circumference of this pressure chamber part 21 is approximately the same size or only slightly larger than the outer width of the inner circumference of the pressure chamber part 20, but the cross-sectional areas of both pressure chamber parts 20, 21 can be approximately the same size or that of the pressure chamber part 20 slightly larger than that of the pressure chamber part 21 can be.
- the inlet 27 sucks adjacent to the inside of the cap end wall 14 from the inside of the holder 10 via an inlet valve 28, the valve housing of which is formed in one piece with the holder 10 and expediently approximately axially parallel to the axis 9 so that it connects to the inner circumference of the sleeve jacket 13 in such a way that it connects via the outer and / or inner end face of the cap end wall 14 protrudes.
- the valve housing of the outlet valve 30 is fastened as a separate component by a snap connection to a socket on the inside of the end wall of the cap shell 18 from the open side of the piston 17 and is also approximately axially parallel to the axis 9.
- an intermediate piece 31 is fastened with sufficient friction and axially limited in relation to the cap end wall 14, which engages with an outer circumference of a casing 32 in the boundary of the assembly opening 15 and both one of the discharge device 1 and of the discharge unit 2 or the media storage 3 forms a separate or detachable component.
- the intermediate piece 31 is expediently an annular cap which forms an inner annular shoulder 33 at one end of the casing 32 for fastening or tensioning the discharge unit 2 on the storage container 3.
- the intermediate piece 31 has separate fastening surfaces for the discharge device 1, the discharge unit 2 and the storage container 3, for which the fastening surface is formed by a thread 34 on the inner circumference of the jacket 32.
- the intermediate piece 31 is used for attachment to the storage neck 35 of the storage container 3 so that the jacket 32 on the storage neck 35 Extends over the outer circumference and with the front shoulder 33 an annular flange of a base body or housing 36 of the discharge unit 2 is tensioned against the end face of the storage neck 35, optionally with the interposition of a seal; the housing 36 then protrudes into the storage container 3 without contact with respect to the inner circumference of the storage neck 35, and the casing 32 is firmly seated between the outer circumference of the storage neck 35 and the inner circumference of the sleeve casing 13.
- the parts engaging in the mounting opening 15 can also be axially and / or radially non-contact with respect to the holder, so that the holder forms only one receptacle.
- the discharge unit 2 forms a discharge unit which is fully functional in itself or also without connection to the discharge device 1, in particular a thrust piston pump, in the housing 36 of which lies approximately in the axis 9, a pressure space 37 which can be narrowed by a pump piston is provided.
- the open end of the housing 36 lying within the holder 10 is closed with an annular cap-shaped housing cover 38 which forms the ring flange for supporting the front shoulder 33 and how the intermediate piece 31 lies completely within the holder 10 or does not protrude beyond the open end thereof.
- a hollow actuating shaft 39 which lies approximately in the axis 9, projects through the housing cover 38 to the outside and is connected by an axial plug connection to the shaft 23 which overlaps it and in the starting position extends approximately up to the housing cover 38.
- the actuating shaft 39 serves to actuate the discharge or pump actuation of the discharge unit 2 and is therefore e.g. connected in one piece to the associated pump piston.
- the actuating shaft 39 forms the associated section of the outlet channel 26, which may be connected to the pressure chamber 37 with the interposition of an outlet valve, it being possible for a valve body of the outlet valve with a shaft to lie within the actuating shaft 39 and thus within the shaft 23.
- the through opening in the housing cover 38 for the passage of the actuating shaft 39 is so wide that the shaft 23 can penetrate into the housing cover 38 or the housing 36 as far as the end position.
- the housing 36 there is also a return spring 40, which is located approximately in the axis 9, for the return of the discharge unit 2, which is expediently located within the pressure chamber 37, the pump piston and / or the actuating shaft and can also be supported as a valve spring on the valve body of the exhaust valve.
- This return spring 40 also serves to return the discharge device 1 to the starting position.
- the housing 36 has an inlet 41 for medium, which is connected to the pressure chamber 37 via an inlet valve 42 and through the inserted medium from the lower region of the storage container 3 via a riser pipe 43 or the like is sucked into the pressure chamber 37 during the return stroke.
- the axial length of the housing 36 is measured without the riser pipe 43, it lies within the holder 10 with more than half of its length and becomes the total length of the discharge unit 2 including the actuating shaft 39 also measured without a riser pipe 43, more than half of its length lies within the discharge device 1.
- the associated end of the housing 36 formed by the housing cover 38 and projecting beyond the outside of the end wall of the intermediate piece 31, is expediently located at a short distance from the inner end face of the cap end wall 14, for which purpose rib-like projections 44 project evenly over the inside, on which on the one hand the housing 36 with the associated end face of the housing cover 38 and on the other hand the intermediate piece 31 with its end face can rest.
- the inlet 27 In the annular space between the outer circumference of the housing cover 38, the inner circumference of the sleeve casing 13, the intermediate piece 31 and the cap end wall 14 there is the inlet 27, which can suck in air from the outside via the axial grooves along the outer circumference of the intermediate piece 31.
- a cap-shaped or similar cover housing 45 is expediently provided, which at least partially closes this open side and fits tightly against the outer circumference of the base body 4 or the outer casing 11 so that it still protrudes beyond the end associated with the end wall 12 and therefore forms a relatively uniform transition from the discharge device 1 to the bottle belly of the storage container 3.
- the cover housing 45 has, in an end wall adjacent to the open end of the outer casing 11, a through opening which is relatively closely matched to the cap casing 18 and through which the piston casing 18 forming the piston skirt of the piston 17 projects outwards.
- the piston 17 expediently does not strike the end wall 12, but this end position is also determined for the discharge device 1 by the pump piston of the discharge unit 2 at the end of the associated cylinder barrel.
- the holder 10 Since the holder 10 is closely adapted to the inner circumference of the cap jacket 18 except for the narrow, approximately annular transition opening between the two pressure chamber parts 20, 21, the holder 2 acts in the pressure chamber part 21 as a displacement body, which, however, does not act like a sealed piston 17 his career of the cylinder formed by the cap jacket 18 is guided.
- the discharge device 1a is shown by itself, that is, without a discharge unit, storage container, intermediate piece and nozzle insert.
- the movable component 5a can be on the inner shoulder of the annular
- the end wall of the deck housing 45a can be fixed by a stop, which is to be attached from the handle 7a before fastening the nozzle insert and belongs to the base body 4a.
- the free end of the shaft 23a lies completely within the through opening 24a and approximately in the plane of the bottom of the holder 10a.
- the outer jacket of the pressure chamber part 20a is formed by a bellows 11a folded in multiple rings, one end of which is in the form of an annular flange on the inside of the end wall 12a and the other end in the form of an annular flange is fastened on the inside of an annular disc collar 17a which is attached to the associated end of the cap jacket 18a protrudes outwards and serves to stop against the cover housing 45a.
- the bellows 11a can be designed resiliently in the manner of a return spring, so that its force is sufficient, at least in the state according to FIG. 2, to return the discharge device 1a to its initial position and to hold it there.
- the outward-facing end flanges of the bellows 11a are attached to the base body 4a or to the component 5a appropriately by adhesion, for example welding or ultrasonic welding, so intimately that there is practically a one-piece design with the base body 4a or the component 5a because the materials overlap in the area of the connecting surfaces.
- the bellows 11a which is only directly adjacent to the inner circumference of the casing of the cover housing 45a at a gap distance, ensures a very good seal of the pressure chamber, because no or only a single sliding seal 25a is required for its sealing.
- an essential pressure chamber part 20a is located on the outer circumference of the cap-shaped holder 10a and because the ring width of the other pressure chamber part 21a is many times greater than the wall thicknesses of the base body 4a or the component 5a mentioned, there is a high delivery volume with a very short overall length.
- the guide webs 22a are extended beyond the inner end face of the ring flange 17a so that they can form a support for the inner circumference of the bellows 11a, on which the individual folding rings are guided with increasing folding with their inner circumferential edges and are thereby secured so that the bellows 11a cannot buckle radially inwards.
- the design according to the invention is also particularly suitable for such discharge devices with which a liquid medium with the addition and mixing with air is developed into a foam and is to be discharged as stable foam as possible.
- the mixing or foaming device is advantageously located within the nozzle insert.
- All described configurations, components, units and rooms can only be provided once or in a plurality of two or more, e.g. in order to be able to effect successive and / or simultaneous multiple fluid discharge from possibly multiple separate fluid or pressure sources from one and / or several outlet openings.
