[32] according to of the present invention one favourable feature, be formed with distribution wall 123 inwalls 1232 with an eddy-current system 126, this eddy-current system can rotate eddy current eye centering on dispensing orifice with the form of eddy current by the drive fluid product.Therefore, a dispensing orifice passes distribution wall 123, and this distribution wall preferably forms a monomer spare with pushing wall 121 and guiding wall 124, and this distribution wall comprises an inner surface that forms with an eddy-current system.
[33] guiding wall 124 comprises a barrier strip 1241 on its outer surface, and described barrier strip is used for cooperating with the interior flanging 1141 of guide sleeve 114.In the annular space that guiding wall 124 forms between guide sleeve 114 and garlands portion 113.Barrier strip 1241 can make the button and the pump housing connect together, therefore described button can only axially move one section range, and this range is definite by the distance of the bottom of lower end of separating guiding wall 124 and the annular space that forms between sleeve 114 and garlands portion 113.
[34] among this embodiment, piston parts 130 comprise that a sealing is slided and are entrenched in the differential piston that the main piston 136 and in the main tube 117 is formed by two lip limits 132,133 that lip limit 132,133 seals slidably and contacts in the tube that the inner surface 1232 by distribution wall 123 forms.Piston parts 130 preferably form in monomer spare mode.132,133 1 on lip limit extends on another, and the spacing greater than the axial range of eddy-current system 126 of being separated by.In resting position shown in Figure 1, the inner surface 1232 on the upper lip 132 contact eddy-current systems 126, and lower lip 133 contacts inner surface 1232 at eddy-current system below 126.Therefore, eddy-current system except being formed at the space between two lip limits 132,133, can not with the button internal communication.This relates to a resting position, and on this resting position, piston parts 130 are actuated to rely on by spring 140 and pushed wall 121, and described spring 140 abuts on the shoulder 1131 on the one hand, and rests on the other hand below the platform 131 that piston parts 130 form.In addition, two lip limits 132,133 form on the neighboring of platform 131.The platform heart therein can backstop be to push stopping in the newel post 1213 that inner surface 1212 places of wall 121 form.Can think that differential piston is formed by the platform 131 that forms two lip limits 132 and 133.Piston parts 130 also form an axial centre bar 137 that extends away from pushing wall 121 from platform 131.These axial stem 137 parts are entrenched in the inlet socketed pipe 116 of the pump housing 110 formation.Bar 137 forms a valve type portion 138, and its corresponding type portion 1161 that is used for forming with sleeve 116 cooperates.In other words, will see that the bar 137 that cooperates with sleeve 116 forms an inlet valve of a pump chamber 1 usefulness as following.On the other hand, piston parts 130 form a piston ring 135, and main piston 136 forms in the lower end of this piston ring.Piston ring 135 with concentric mode extend in axial stem 137 around, pass the circular passage that platform 131 extends thereby between them, form one, fluid product is passed by eyelet 134 in this circular passage.
[35] pump housing 110, button 120 and piston parts 130 form a pump chamber 1 together, pump chamber 1 extends between main tube 117 and the socketed pipe 116 continuously, between piston ring 135 and the axial stem 137, in eyelet 134, and at platform 131 and push between the inner surface 1212 of wall 121.Therefore, the upper surface of platform 131 and inner surface 1212 form the wall elements of pump chamber 1.In resting position shown in Figure 1, spring 140 promotes piston parts 130, it is reclined push wall 121.Cooperate the inlet valve that forms to open between axial stem 137 and the socketed pipe 116.The socket joint that the inner surface 1232 of the action wall 123 shown in two lip limits 132,133 of differential piston and the dotted line of Fig. 3 a forms touches.
[36] by pushing the power that applies on the outer surface 1211 of pushing of wall 121, button moves axially with respect to the pump housing 110.Because the piston parts are blocked in and push on the wall, so the piston parts are promoted by button.At first, the effect that button moves is to close inlet valve: axial stem 137 more in depth is fitted in the socketed pipe 116, up to produce the slipper seal contact between socketed pipe or bar.Therefore, pump chamber 1 is isolated with holder 5.From this constantly, the product in the pump chamber 1 can be under pressure.Because fluid product is incompressible, total dischargeable capacity of pump chamber must keep constant.But because main piston 136 is deep in the tube 117, therefore reduced the volume of pump chamber bottom, therefore should produce new volume.Because differential piston moves away from pushing wall 121 ground, thereby to produce new volume be possible.Such effect is to be slided in distribution wall 123 in lip limit 132 and 133.Therefore move on the lip limit, arrives eddy-current system 126 places up to upper lip 132.This point is shown in Fig. 2.At this moment, the band hydraulic fluid product in the pump chamber obtains one and passes the passage of eddy-current system and dispensing orifice outflow.The position of upper lip 132 dots among Fig. 3 b.Therefore, as long as the pressure in the pump chamber can overcome the power of spring 140, it is open that passage just keeps.In case the pressure in the pump chamber is reduced to below certain threshold value, spring 140 is pushed differential piston to shown in Fig. 3 a resting position again.Then eddy-current system and dispensing orifice are isolated with pump chamber again.
Can notice that [37] upper lip 132 directly contacts with fluid product, and lower lip does not contact directly with fluid product.Therefore, upper lip is slided in the top of pushing the tube that forms between wall and the eddy-current system.Yet the surface quality on this top of tube is better than the surface quality of the bottom of extending below eddy-current system, takes out core rod (broche de moulage) and may damage this bottom.
[38] Fig. 3 a and 3b are illustrated in a non-limiting specific embodiments of the eddy-current system that forms in the distribution wall of distributor gear of the present invention.This eddy-current system comprises at least one tangential swirl channel 1262.The tangential passage that has three equal angles to distribute among the figure.On the other hand, eddy-current system also comprise one with the minor air cell, center 1261 of dispensing orifice 125 accurate centerings.Alternatively, eddy-current system can comprise that one allows to supply with the circumference supply ring 1263 of all swirl channel 1262.If necessary, eddy-current system can be reduced to a unique swirl channel that is connected with the minor air cell, center.
[39] of the present invention one favourable being characterised in that, piston parts 130 are pushed to pushes wall 121, and moves away from described under the effect that the pump chamber internal pressure increases with pushing wall.That passes the platform 131 that forms differential piston by means of fluid product passes through eyelet 134, and this is especially possible.Therefore also we can say and push the wall elements that wall forms pump chamber.
[40] owing to upper lip 132 is slided on the top of sliding cylinder in the mode of sealing, therefore differential piston away from push wall described move and distribution wall in the eddy-current system that forms to combine demoulding aspect be favourable, described top wherein can not be subjected to being destroyed because of taking out core rod, and described core rod is formed for the minus chamber (empreinte n é gative) of molded eddy-current system.
What [41] can also note is, arrival resting position below the flanging 1141 time in barrier strip 1241 that guiding wall 124 forms abuts in.
[42] on the other hand, the axial lead of button guaranteed by the axial lead of the guiding wall 124 between sleeve 114 and the garlands portion 113 on the one hand, and is entrenched in respectively in the main tube 117 and the socketed pipe 116 that enters the mouth by piston ring 135 and axial stem 137 on the other hand and is guaranteed.
[43] implement modification for two of Fig. 4 a and 4b presentation graphs 1,2 embodiment.
[44] in the modification of Fig. 4 a, the precommpression back-moving spring to be making with the form of 210 one-tenth one of the pump housing, and represents with reference number 2171.Spring extends in the extended line of main tube 217, and abuts in platform 231 times, and platform 231 and its two lip limits 232,233 form differential piston.Spring 2171 therefore with concentric manner extend in the ring 230 that forms main piston 236 around.Except that back-moving spring, the distributor gear 200 of Fig. 4 a can be identical with Fig. 1,2 distributor gear.
[45] in the embodiment of Fig. 4 b, distributor gear 300 comprises that one forms the back-moving spring 3311 of a single element with piston parts 330.Or rather, spring 3311 begins to extend from the lower surface of platform 331.It abuts on the shoulder 3331 of the pump housing 310 formation in its lower end.Except the special shape of spring, distributor gear 300 can be identical with Fig. 1,2 distributor gear.
[46] implement in modification at these of Fig. 4 a and 4b, distributor gear includes only three element, i.e. a pump housing, a button and piston parts, and precommpression back-moving spring or be integrated in the pump housing perhaps is integrated in the piston parts.
