As for example seen from Fig. 6,10 and 11, bar 61 has the annular lip 124 extending radially outwardly, and this annular lip 124 carries fingers 70 in the end of radially outward pointing to of this flange 124.Flange 124 is provided with the shoulder surface 126 of axially outwards pointing to of radially extending, and first this shoulder surface 126 is incorporated in the outside face of fingers, and as curved face part 128, this curved face part 128 is incorporated in the camming surface 73 that roughly conical butt is arranged.Camming surface 73 is held within it and is ended at radially extension shoulder 74 places that axially inwardly point to.The inside face of fingers 70 is depicted as has roughly frusto-conical portion 129, and this frusto-conical portion 129 is incorporated in the interior shoulder surface 130 on flange 124 at its lower end.
Outside from flange 124, bar 61 axially extends forward, as 136，Gai location division, Frusto-conical location division 136, outwards comes to a point gradually and at its axial outer end place, carries discharge orifice 64 with the 134 merging ，Gai export departments 134 of export department of substantial cylindrical.
The chamber 102 of buckle member 100 is set to have the shape very corresponding with the anterior shape of waiting to be contained in piston element 57 wherein.In chamber 102, the interior upper surface 36 of outer end wall 32 is very corresponding to the size on the shoulder surface 126 of the flange 124 on piston element 57.The inside face 114 of inner end wall 112 is very consistent with the shape and size of the shoulder 74 of the fingers 70 of piston element.
As seen best in Fig. 7, export 120 and extend through sidewall 108, sidewall 108 ends at camming surface 136 places of the sideward directed with inner edge 138 and outer rim 140.Each frustoconical inner surface 110 of sidewall 108 all ends at forward inner edge 138 places.
Fig. 8 is carried out to reference, and Fig. 8 is schematically illustrated in piston element 57 with the buckle member 100 in two different situations that do not connect arranged in orientation.First, piston element 57 is depicted as radially do not connect arranged in orientation before buckle member 100, from this, radially do not connect orientation, piston component 57 can radially not connect orientation along the direction radial water level land being represented by arrow 143 from radially not connecting to be orientated to move to connect orientation and from connecting to be orientated to move radially.Fig. 8 also shows axially do not connect the piston element 57 of arranged in orientation, from this, does not axially connect orientation, and piston element 57 can be by the moving axially of direction along arrow 145 axially connect orientation from this and moves to and connect orientation.This has connected orientation for example shown in Fig. 5, each width of 9 and 12.
Figure 12 shows the top view of Fig. 5, piston element 57 with buckle member 100 in connecting in orientation.As what can see in the dotted line in Figure 12, see that two in fingers 70 are positioned under inner end wall 112, the shoulder 74 of fingers 70 and inside face 114 tight joint of upper end wall 112, as what see in the bench section in Fig. 9, camming surface 73 and frustoconical inner surface 110 tight joint of sidewall 108 and upper surface 36 tight joint of flange 124 and outer end wall 32.From this, connected orientation, by piston element 57 with respect to radially the relatively moving of axis 66, can be by piston element 57 from taking off with the engaging of buckle member 100.In this moves radially, camming surface 73 on jerk-finger 70 engages with camming surface 136, and obviously engage with the inner edge 138 of camming surface 136, when piston element 57 radially moves forward, this joint makes to be positioned at elasticity fingers 70 on the opposite side of outlet 120 radially to intrinsic deflection, to allow the jerk-finger 70 of this deflection to move radially by exporting 120.Figure 13 shows such situation, wherein piston element 57 radially moves forward from connecting orientation, and two relative fingers 70 of contiguous each claw 106 are fully radially to intrinsic deflection, thereby these fingers 70 can be radially forward by outlet 120.
In the situation that fingers 70 is in the intrinsic structure of biasing not, from connecting the process that orientation moves radially forward shown in Figure 12, fingers 70 starts to deflect into the deflection structure from intrinsic structure with different radially expanded ranges.From this deflection structure, each fingers 70 is because its intrinsic elasticity is biased, thereby turns back to intrinsic structure.From the coupling configuration shown in Figure 12, when starting radially to move forward, the joint of the forefront of the frustoconical inner surface 110 of sidewall 108 will at least contribute to radially inwardly to promote fingers 70 during piston element 57 starts to move radially.After starting movement, engaging and will cause the further deflection of fingers 70 between the camming surface 73 on fingers 70 and the inner edge 138 of camming surface 136, and along with piston element 57 is further outwards mobile, the camming surface 73 of fingers 70 will lean against and be bonded in the outer rim 140 of camming surface 136 leaning against on camming surface 136 and when leaving entrance 120 subsequently.
Outlet 120 is limited by the tank circuit 38, and this tank circuit 38, through outer end wall 32, enters central opening 104 from the leading edge 40 of actuator plate 32.The tank circuit 38 has sidewall 142, and described sidewall 142 intervals obtain enough opens, thereby they allow conical butt location division 136 and the cylindrical outlet portion 134 of piston element 57 radially to pass through thus.Similarly, as directed, the side wall surface 144 that is carried on the outlet 120 in inner end wall 112 is radially spaced enough large distance, thereby they allow bar 61 radially to move forward thus.From radially not connecting and being orientated shown in Fig. 8, piston element 57 can radially move backward to and connect orientation.In this radially moves inward, the camming surface 136 that is positioned at the sidewall 108 on the either side that exports 120 engages with the camming surface 73 on fingers 70, so that fingers 70 is radially to intrinsic deflection, thereby as seen in Figure 13, relative fingers 70 is radially inwardly arranged fully, is made them can move inward through camming surface 136 and enter in chamber 102.When piston element 57 moves towards the position coaxial in this chamber from the position of Figure 13, fingers 70 is because its intrinsic elasticity presents the intrinsic structure that it is not setovered.Therefore, in some sense, never connect orientation move radially and connect when orientation at piston element 57, fingers 70 deflects into deflection structure and recovers to present its intrinsic structure rapidly subsequently.
Connecting in orientation, first, due to the shoulder 74 of fingers 70 and the inside face 114 of inner end wall 112 engages, the shoulder of flange 124 surface 126 engages with the upper surface 36 of outer end wall 32 and refers to that 70 camming surface 73 engages with the inside face 110 of sidewall 108, so piston element 57 resistances are from connecting orientation movement in axial direction.Connecting in orientation, by the fingers 70 engaging with inside face 110 sidewall 108 under intrinsic structure, resisting piston element 57 moving radially with respect to buckle member 100.
With reference to figure 8, piston element 57 also can move to and connect orientation by moving to axial from the axially connection orientation shown in Fig. 8.When so moving axially, camming surface 73 on fingers 70 forms and engages with the side wall surface of inner end wall 112 144, so that the intrinsic structure that fingers 70 is not setovered from it deflects into the deflection structure from intrinsic structure with different radially expanded ranges, thereby allow fingers 70 axially through inner end wall 112, and in the coaxial central opening 104 that extends downwardly into outer wall 32 in the cylindrical outlet portion 134 of piston element and conical butt location division 136.In this axial insertion, can consider piston element 57 to move down the entrance that extends axially defining by the side wall surface 144 by inner end wall 112.Once under the inside face 114 of the axially outside sensing of the axial outwards process of camming surface 73 inner end wall 112 on fingers 70, the fingers that deflects into deflection structure between the side wall surface 144 of inner end wall 112 while moving will reply rapidly to present its intrinsic structure.As seen in Fig. 9, connecting in orientation, chamber 102 forms and makes following inside face coaxial and in fact form the keyway portion be arranged in the first surface of revolution limiting around the rotation of axis 66 by corresponding the first shape around this axis 66, and described inside face comprises a part of inside face 36 of the whole inside face 114 of inner end wall 112, the whole inside face 110 of sidewall 108 and outer end wall 32.Similarly, when piston component 57 is when axis 66 is coaxial, can think that the key portion of outside face of piston element 57 is arranged in the second surface of revolution limiting around the rotation of axis 66 by the second shape, this second shape and the first shape are of similar shape substantially.For providing the shape keyway portion corresponding with the key portion of the outside face of piston element 57, chamber 102 is considered to be conducive to piston element that restriction do not have a rotation shape dropping within the form range being limited by keyway portion to the insertion in chamber 102.
In this respect, when around the rotation of this axis, can think a kind of gyro-rotor of rotation shape representation of key portion of outside face of piston element 57.Chamber 102 has the inwall in this chamber 102 of abundant restriction, only to work as the gyro-rotor of piston element, be size, shape and the structure that will be contained in this chamber, drop on when chamber 102 can be thought during around the rotation of its axis in the gyro-rotor in chamber 102, just allow piston element 57 to be contained in chamber 102.In the situation that the gyro-rotor of piston element does not drop in the scope of gyro-rotor in this chamber, refusal is used this piston element.Chamber 102 relative to keyway shape, determined which kind of of key portion of piston element 57 specifically rotated shape or gyro-rotor can be contained in chamber 102.Preferred embodiment shows the rotation shape of the key portion of piston element 57, the rotation shape in this rotation shape and chamber 102 is basic identical, yet, this not necessarily, the key portion of piston element 57 only needs to have and allows the key quality award from the ministry of piston element 57 to be selected in any rotating part of axis to be assembled to the shape in chamber 102, to be preferably rotation shape or gyro-rotor.
Shown preferred embodiment shows elastic joint flange 67, and this elastic joint flange 67 comprises a plurality of discontinuous circumferentially spaced fingers.This not necessarily.For example, except thering is fingers 70(slit 82 separately, separate described fingers), can also replace with continuous annular element described fingers, still, this member will have the elasticity that allows radial deflection to construct to suitable deflection.
Part in the chamber to be contained in 102 of chamber 102 and piston element 57 has formed three-dimensional keyway and complementary key effectively, enters or leave the deflection of keyway elasticity of demand part.Should be appreciated that and thisly enter or leave deflection that keyway also can be by key, the deflection by keyway or realize by the two the deflection of keyway and key.In the situation that each plane of revolution that passes through to rotate around axis 66 of the keyway portion of buckle member 100 and the key portion of piston element 57 limits, piston element 57 can be in the Arbitrary Relative engagement position around axis 66 rotations in chamber 102.This is preferred, however not necessarily, but various arrangement structures can be provided, to require piston element 57 to be suitably inserted in chamber 102, piston element 57 rotates to the position of rotation of one or more expections around axis 66.
Fig. 1 is intended to illustrate the liquid vessel assembly that comprises liquid vessel 16 and valve module 22, and this liquid vessel assembly, in radially not connecting orientation, is prepared only by radially moving backward, to be connected to shell 14.From the position shown in Fig. 1, the whole beginning level of liquid vessel 12 slides backward the flange 24 that causes shell 14 is contained in the tank circuit 52 between the lowermost wall 17 of fluid chamber 16 and the shoulder that is directed upwards towards.In the situation that forming member 56 with respect to piston chamber, piston element 57 is positioned at suitable extended position, piston element 57 and buckle member 100 will be in radially not connecting orientation, from this, radially do not connect orientation, follow-up further level by liquid vessel 12 and valve module 22 slides backward, and piston element 57 can make it refer to 70 deflections and enter chamber 102 to connect orientation to present.
Fig. 4 is carried out to reference, and Fig. 4 shows at piston element 57 in complete punctured position in the situation that, when liquid vessel 12 slides backward the situation occurring while inserting in shell 14 by level.The flange 24 of this shell is contained in the tank circuit 52 between lowermost wall 17 and the shoulder being directed upwards towards 53 of valve module 22.Yet in punctured position in the situation that, the fingers 70 of the engagement member 67 of piston element 57 is not vertically arranged on the buckle member 100 being carried by actuator plate 32 axially not connect orientation at piston element 57.From the position of Fig. 4, in the first operation of distributing box,, by hand-driven moving lever 31, move straight up the position that actuator plate 32 is positioned under outer engagement member 67 from it, as shown in the arrow in Fig. 4.Buckle member 100 engages with the elasticity fingers 70 of engagement member 67, utilizes this joint, and elasticity fingers 70, radially to intrinsic deflection, allows piston element 57 to enter and be bonded in buckle member 100, thereby presents coupling configuration.
In the process moving up as shown by the arrows in Figure 4 in actuator plate 32, buckle member 100 will as far as possible upwards promote piston element 57 when first engaging with fingers 70, piston element 57 has been placed in to holosystolic position, in this complete holosystolic position, piston element 57 forms moving up of member 56 with respect to piston chamber and is prevented from, for example the inner of the chamber 58 in the inner by piston element 57 and piston chamber formation member 56 incompatible prevention of joining.
In the situation that piston element 57 connects orientation in what be connected to actuator plate 32, in the operating cycle after manual release lever 31, spring 34 will make actuator plate 32 turn back to extended position together with piston element 57.
Fig. 6 is carried out to reference, and Fig. 6 shows elasticity fingers 70 best.In this preferred first embodiment, be provided with six fingers 70, each fingers all represents around the equal segments through the central axis 66 of piston element 57, and each fingers to be all arranged through slit 82 evenly spaced apart each other.
Shown in preferred embodiment in, for example, in Fig. 1, piston element 57 is preferably integral member by plastic material injection mo(u)lding.After the content of liquid vessel 12 has distributed, this liquid vessel 12 and pump assembly 22 integral body thereof preferably can be used as a unit and abandon.Owing to conventionally only wishing that single liquid vessel 22 and the pump assembly 22 that abandons thereof are connected to shell once, therefore, the jerk-finger 70 of piston element 57 only needs to have such elasticity, and this elasticity allows to connect once with actuator plate 32 or be at least no more than several.Thereby, manufacture the plastic material of jerk-finger 70 without can deflection repeatedly and still keeping arbitrarily its elasticity.Thereby jerk-finger 70 can be formed by relatively inexpensive plastic material, although this material has certain intrinsic elasticity, without keeping this elasticity in the deflection circulation repeating.Comprise the piston element 57 of the engagement member 67 that carries jerk-finger 70 or at least its main portion can preferably by plastic material, be formed the element of basic integral body, for example by injection mo(u)lding, form.
In the embodiment in figure 1, piston element 57 allows piston element 57 slips of reciprocally moving to be inserted in the buckle member 100 in actuator plate 32, or enter to have connected as shown in Figure 2 orientation or entered as shown in Figure 4 and axially do not connect orientation, at this, do not connect in orientation, piston element can be independent of actuator plate 32 and move.
Connecting in orientation, the gyroscopic movement of bar 31 makes actuator plate 32 and piston element 57 move axially to distribute a certain amount of fluid 18 between the first static extended position and the second complete punctured position.If liquid vessel 12 in the situation that piston element 57 in the orientation that axially do not connect of Fig. 4, insert, first of bar 31 move actuator plate 32 is moved with respect to piston element 57, until piston element 57 engages and present the orientation of connection of Fig. 2 with buckle member 100.By this way, no matter whether piston element 57 inserts in shell 14 at first to be connected to or not to be connected to actuator plate 32, and distributing box 10 all can operate in order to distributing fluids 18.
For distributing fluids 18, actuator 30 circulates by the gyroscopic movement of bar 31, the gyroscopic movement of bar 31 moves to punctured position by piston element 57 from the first static extended position shown in Fig. 2, then discharge this bar 31, spring 34 makes actuator plate 32 turn back to the first static extended position to complete this circulation.
Advantageously, distributing box of the present invention 10 allows liquid vessels 12 inserting in shell without guarantee that piston element 57 forms member 56 or actuator plate 32 in ad-hoc location with respect to its piston chamber in the situation that.

Figure 21 is carried out to reference, Figure 21 shows the sectional elevation with essentially identical buckle member 100 and displaceable element 57 shown in Fig. 9, yet in Figure 21, chamber 102 in buckle member 100 and each in jerk-finger 57 are all inverted, thereby displaceable element 57 can the orientation that axially do not connect under buckle member 100 upwards move axially to buckle member 100.Embodiment in Figure 21 still can be with the embodiment with Fig. 9 similar mode move radially with not connecting between being orientated connecting orientation.
Figure 22 is carried out to reference, and Figure 22 shows according to another embodiment of buckle member 100 of the present invention and displaceable element 57 with the bench section to similar in Fig. 9.In Figure 22, in fact each fingers 70 all forward, stretches out, and substantially only from the support lugn 124 being arranged on bar 61, extends axially.Each fingers 70 all has the camming surface 73 radially outward pointing to, and this camming surface 73 can contribute to make displaceable element 57 to being moved down into, to connect orientation from the axis of orientation that axially do not connect on buckle member 100.From connecting to be orientated, do not connecting moving radially of being orientated, the axial outer end of fingers 70 is radially radially passed through this outlet to intrinsic deflection with permission fingers 70 by the part around its outlet by this chamber.Each fingers 70 includes the annular groove 280 around it, the annular radial that this annular groove 280 is suitable for the holding inner end wall 112 within it portion that extends internally.In the embodiment of Figure 22, run through whole outlet, through the outlet of radially opening of inner end wall 112, should equal the wide diameter between the surface 144 of inner end wall 112 forward, yet outlet will have the diameter radially reducing along sidewall 108, make to refer to that 70 radially moving inward of far ultraviolet end allows radially to shift out by this outlet.
Figure 23 shows according to embodiments of the invention, and in this embodiment, engagement member 67 comprises disk, and this disk radially extends and be suitable for making the in axial direction deflection of far-end of this disk from bar 61.Disk 67 is depicted as has axially conical butt camming surface 73 outside and that inwardly point to.As seen best in Figure 23 and Figure 25, the outlet 120 of passing sidewall 108 comprises the exit slot 220 radially extending with lower surface 286 and upper surface 284.Be close to the central part of this outlet 120, the lower surface 286 of slit 220 is in the height identical with the upper surface 36 of outer end plate 32.Yet the lower surface 286 of slit 220 is along with it extends radially outwardly and upwards raise gradually from the tank circuit 38.In the situation that piston element 57 is in coupled position as shown in Figure 24, when displaceable element 57 starts radially to move radially along the direction that exports 120, camming surface 73 on cushion disk(-sc) 67, by the most front lower bond of the lower surface with exit slot 220 286, causes cushion disk(-sc) 67 axially to upward deflect at its front end place.Along with further radially moving forward of piston element 57, cushion disk(-sc) 67 will limpen, and make thus its outer far-end K/UP, thereby mate the curvature of exit slot 220 and thereby allow cushion disk(-sc) 67 radially outward to slip over this slit.Yet, in the situation that displaceable element 57 is arranged in coupled position, the intrinsic elasticity of cushion disk(-sc) 67 will make disk 67 present the not intrinsic structure of biasing shown in Figure 24, thereby displaceable element 57 is coaxially fixed in buckle member 100 to connect orientation.Although only shown in Figure 24, but a certain mechanism is preferably set and prevents that displaceable element 57 from axially moving up when it engages with member 100, and in order to realize this preferred but unnecessary target, a plurality of elasticity fingers 272 are set, when axially inserting, described a plurality of elasticity fingers 272 can engage with the inside face 114 with inner end wall 112 through blocking after inner end wall 112 and having the buckle face 273 radially inwardly pointing to.
Figure 25 shows the front elevation of the embodiment shown in Figure 23 and Figure 24, but in part not in coupling configuration, in this part not in coupling configuration, displaceable element 57 has moved forwardly in described outlet, make cushion disk(-sc) 67 be contained in exit slot 220 and at its far-end, upward deflect, thereby present the curved configuration through the exit slot 220 of sidewall 108, for example, when the crooked slit 220 in the front portion of sidewall 108 is just passing through in the maximum gauge portion of cushion disk(-sc) 67.
Figure 26 is carried out to reference, Figure 26 shows and the buckle member 100 being equal to shown in Figure 19, yet in Figure 26, sidewall 108 and inner end wall 112 are depicted as elasticity fingers 370, and described elasticity fingers 370 makes progress and extends radially inwardly to far-end 304 from being fixed to the fixed end 302 of outer end wall 32.Each in these members 370 be all resilient and radially outward deflection with contribute to make displaceable element can utilize relative axially or move radially and never connect orientation and move to and connect orientation.The elastic component 370 being positioned on the either side that exports 120 is particularly suitable for directly remotely moving each other, along the direction shown in the arrow 372 in Figure 26, moves, and this can contribute to increase the width that displaceable element 57 can move radially the outlet 120 of passing through.Although preferably make any displaceable element 57 carry can elastic deflection member, for example refer to 70, but be to be understood that, below also in those skilled in the art's skill: adopt buckle member 100 as shown in Figure 26, thereby the flexible member of this buckle component load-bearing, this elastic component is fully mobile to be moved radially by described outlet to allow displaceable element 57 never to connect orientation.
Figure 28 is carried out to reference to Figure 37, Figure 28 shows the outermost view of piston element 57 to Figure 37, this piston element 57 is constructed with following arrangement structure: on bar 61, form resilient radial and extend disk 67, this disk 67 can be suitable for axially and/or radial deflection.Piston element 57 is only depicted as has cushion disk(-sc) 67, and bar 61 extends downwardly into discharge orifice 64 through this cushion disk(-sc) 67.Yet as shown in the dotted line of Figure 28 shown in meaning property, the bar 61 of piston element 57 is not only from disk 67 to downward-extension, and extends upward.
In Fig. 6, slit 82 extends axially through engagement member 67.By contrast, as shown in Figure 28, slit 84 extends axially axial closing end or closed end 514 from axial open end 512 from the lower surface 507 axially outwards pointing to of engagement member 67, and slit 84 is limited between two circumferential isolated sidewalls 516 and 518.Closed end 514 also forms the lower surface at top 505.Also can see, the radial opening end 530 of slit 84 from the evagination wheel face 508 radially outward pointing to radially extends to radial closure end or the closed end 522 between two circumferential isolated sidewalls 526 and 528.
As seen in Figure 29, each refers to that 70 annular grooves that also extend by axial and circumferential or slit 308 radially separate with some part of engagement member 67.As seen best in Figure 33, slit 308 extends axially axial closing end or closed end 312 from axial open end 310 from the lower surface 507 axially outwards pointing to of engagement member 67, and slit 308 is limited between two sidewalls that are radially spaced 320 and 322.As shown in Figure 31, because the radial distance between sidewall 320 and 322 is little at pars intermedia 326 places at circumferential end 324 places' ratios, so the radial width of each slit 308 is different.
Being arranged on axially extended slit 84 and 308 in circular engagement member 67 contributes to realize the intrinsic structure that elastic component 67 never setovers and deflects into deflection structure, the intrinsic structure of for example never setovering at elastic component deflects in the process of deflection structure, and isolated sidewall 526 and 528 is relative to each other shifted and/or isolated sidewall 320 and 322 is relative to each other shifted.Slit 84 and 308 provides shown in Figure 33 and has reduced bridge portion 309 for the thickness in the size reduction bridge portion of bridge portion 85 and Figure 38, at described bridge portion place, the distortion of engagement member and bending may more easily occur, thereby contribute to engagement member deflection as expected.Compare with the other parts of engagement member, the axial dimension of described bridge portion reduces, and provides part this or that other width reduces to adopt as a kind of method, is used to faying flange that desirable flexibility is provided.
Figure 34 shows in the situation that the piston element 57 of disk 67 in identical inflection point to Figure 37, if disk 67 is carried out radial compression and/or also along arrow 516 and 518 directions as shown in figure 37, disk 67 is carried out to axial compression between two arrows 512 as shown in Figure 34 and Figure 37 and 514, described compression acts on respectively on the surface 508 of two radially relative fingers 70, and disk 67 will present this inflection point.Because cushion disk(-sc) 67 is by elastomeric material, preferably by elastic body, plastics or rubber, made, so disk 67 will present Figure 34 to the inflection point shown in Figure 37, refer in 70 two axially inwardly and on limit radially to intrinsic deflection.Figure 34 has schematically shown the solid line that shows the border between Different Plane on upper surface 506, and upper surface 506 can present the state shown in Figure 34 when deflection.These planes 520 are shown to contribute to make the variation of upper surface 506 when the deflection visible.
Figure 36 and Figure 37 show best axially upwards and on limit radially to the finger 70 of intrinsic deflection.
Each refers to that 70 are only attached to piston element 57 effectively by top 505, this top 505 by slit 84 bridge joints between adjacent fingers 70, as shown in Figure 32, and this top 505 by slit 308 bridge joints from fingers 70 radially inner roughly circumferentially extend between downward-extension rib 510, as shown in Figure 33.Can select relative flexibility, size and the thickness of top 505 and fingers 70 to strengthen to illustrate the expection deflection capacity that refers to 70.
