Fig. 3 shows conveying mechanism or pump in the form of diaphragm pump 110, and the diaphragm pump has magnetic actuator 111, by described
The straight reciprocating motion of magnetic actuator in this embodiment generates pumping action.For simplicity, especially electromagnetic wire is not shown
The electrical contacts of circle.Magnetic actuator 111 has armature 118, and the armature is in end side via thermoplastic injection encapsulation piece 119 and bullet
Property body diaphragm 117 connect.Armature is configured to sunk armature, is surrounded radially by electromagnetic coil 14.Magnetic actuator also has
There is compression spring 18, the compression spring is by elastomer diaphragm via armature (in the state that electromagnetic coil 14 is not powered on) at this
The valve seat of valve plate 24 is pressed onto in the region of the sealing protuberance 480 of armature in other words on seal receptacle 48.It is constituted in pump as a result, integrated
Closure valve 130 (48,480), relative to diaphragm pump in suction side under the unpowered state that the closure valve is shown in FIG. 3
Valve flow into other words valve 113 seal diaphragm pump operating room 120.It therefore ensures that, after the exhaust gas of application in a motor vehicle
It is not situated between in the case of in reason (it is used to provide the liquid adjuvant for making nitrogen oxides restore in the case where vehicle is parked)
Matter can reach the metering valve being arranged on exhaust piping from case (mighty torrent protects (Flutungsschutz)) so that conventional defeated
Sending during operation does not have delivered volume loss across the operating room of diaphragm pump, and makes the seal receptacle in the case where there is ice pressure
It can be opened with the power of renitency spring 18 and the system can be made to lighten the burden.In addition, Fig. 3 is also shown in the case where diaphragm pump
Under be arranged in a way known, in outflow valve 115 on the pressure side, passed through via the medium for flowing into valve and operating room is inhaled into
It is continued to be transported to consumption position, such as metering valve as described above by the outflow valve.
Under running conditions, armature is close on valve plate in the region of sunk armature geometry together with diaphragm
It is moved between envelope seat supports portion 48 and backstop 122.It is thereby achieved that two backstops, one of backstop are arranged in figure 3
In following seal receptacle support portion, since the buffering by realizing diaphragm construction by elastomer diaphragm hardly causes to make an uproar
Sound.In the ongoing illustrated embodiment, attract the upper backstop of armature 118 via sunk armature geometry in energizing magnets
122 based on metal stopper.Here, additional vibration reducing measure can optionally be arranged, for example, by be arranged rubber parts or
Installing the spacing washer made of damping material.
In the operation of diaphragm pump, armature 118 is in the cylindricality hollow chamber 128 for example at least partly surrounded by electromagnetic coil 14
Middle movement.There is armature spring housing 126, the spring housing to be unlimited in the side away from operating room.Spring 18 is stretched in the side
Into in spring housing, the spring supporting at it on the matrix or magnetic circuit tank 123 of diaphragm pump, stretch out from spring housing
On end.The ventilation orifice 121 for making spring housing or cylindricality hollow chamber 128 divulge information is provided in the tank of circuit.So-called magnetic
Circuit flange 124 (R ü ckschlusskragen) surrounds hollow chamber 128, nothing along the major part of the vertical extension of hollow chamber
By how radially bending on the side towards operating room of hollow chamber and there towards the direction of electromagnetic coil.It is returning
Between road flange and hollow chamber there are be for example configured to sleeve, it is with the magnetic back (R ü cken) for reducing magnetic resistance
Bearing 129 so that obtain the guiding of the lower resistance and long plane of armature 118.
The present invention may be implemented complete injection encapsulated and equipped with welding rib 127, so as to by advantageous interconnection technique
Such as laser welding is fixed in pump case 125.Operating room 120 of the diaphragm 117 to be surrounded by it is so that also can
Convey gaseous medium or the liquid with gas componant.
Fig. 4 shows the enlarged drawing of magnetic actuator 111 (electromagnetic coil is not shown) with cross-sectional side view.Armature is by magnetic conduction material
Material composition, the material be arranged on the end side of its operating room 120 towards diaphragm pump there are two concentric side pocket 133 or
135 so that the thermoplastic injection encapsulation piece 119 on end side of armature may be implemented to connect with being mechanically fixed for armature.Here,
Armature is provided with so-called free segment 137 (Freistich) so that can completely attract in the state that electromagnetic coil is powered
Avoid armature wide in its cylindrical extension and the diameter in the connection height of thermoplastic injection encapsulation piece 119 in the case of armature
It is blocked in region between the region of degree.The thermoplasticity of the middle layer or the middle layer side that be made of thermoplastic material is noted
Mould encapsulation piece 119 has side pocket 131 in side, to which the elastomer diaphragm 117 of application on the intermediate layer equally may be implemented
It is connect with being mechanically fixed for middle layer.Middle layer elevated portion with circular on end side, the elevated portion is located at again to be made
On the side towards operating room for the elastomer diaphragm of sealing protuberance 480, the sealing protuberance can be with the seal receptacle of valve plate 24
48 such as collective effect as shown in Figure 2.The sealing lip 139 of elastomer diaphragm is used in edge enduringly Fluid Sealing
Ground limit operating room, and the fringe region of the thickening of elastomer diaphragm is used for the elastomer diaphragm mechanical caging in diaphragm pump
In mechanistic organization structure, such as in the region of valve plate 24.
Armature-membrane combination is especially designed, so as to realize the improvement attachment of the elastomeric material of diaphragm.For this purpose,
The thermoplastic on spray to cast in the metal part of armature.In addition at least one mechanical side pocket, combined by suitable material
And by using attached dose of the properly increasing for elastomer, it is ensured that these materials are mechanically fixed connection, in no thermoplasticity
The connection is not present in the case of interbed.In the case that using suitably increasing attached dose, thermoplastic interlayer compares working masks again
Elastomeric material be preferably attached on metal armature.Additionally, the surface structuration of such as armature end side can be set, with
Just the closer of pairing material is supported to be interconnected.
Fig. 5 equally shows the armature-membrane combination substituted with cross-sectional side view.As according to the embodiment of figure 4
In same or similar component part be provided with identical reference numeral.Here, rubber or elastomer diaphragm 117 pass through transverse holes
It 500 and is mechanically held in plastics or thermoplastic injection encapsulation piece 119 by axial hole 600.
The structure can not only be used in the system of positive displacement work but also can be used in by pressure controlled system,
In the system for example in exhaust after-treatment region, but also can especially it exist in medical technology or in the case of coffee machine
Such pump is packed into different conveying devices, these conveying devices should be closed in the state of being not powered on.
