As for example seeing that bar 61 has the annular lip 124 that extends radially outwardly from Fig. 6,10 and 11, 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 of axially outwards pointing to 126 of radially extending, and at first incorporate in the outside face of fingers on this shoulder surface 126, 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 in its lower end is incorporated interior shoulder surface 130 on the flange 124 into.
Outside from flange 124, bar 61 axially extends forward, and as Frusto-conical location division 136, this location division 136 outwards comes to a point gradually and merges with the export department 134 of substantial cylindrical, and this export department 134 carries discharge orifice 64 at its axial outer end place.
The chamber 102 of buckle member 100 is set to have and the unusual corresponding shape of the shape of the front portion 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 on the piston element 57 124.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 seeing best among Fig. 7, outlet 120 extends through sidewall 108, and 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 inner edge 138 places forward.
Fig. 8 is carried out reference, and Fig. 8 is schematically illustrated in piston element 57 with the buckle member 100 under two different situations that do not connect arranged in orientation.At first, piston element 57 is depicted as radially not connect the front of arranged in orientation at buckle member 100, radially connect orientation from this, piston component 57 can be along being moved to and connect the orientation and move radially radially to connect and be orientated from connecting orientation from radially connecting orientation by the direction radial level ground of arrow 143 expressions.Fig. 8 also shows axially not connect the piston element 57 of arranged in orientation, axially connects orientation from this, and piston element 57 can move to and connects orientation by axially connecting orientation along the moving axially of direction of arrow 145 from this.This has connected orientation for example shown in Fig. 5, each width of cloth of 9 and 12.
Figure 12 shows the top view of Fig. 5, and piston element 57 is in buckle member 100 and connects in the orientation.As what can see in the dotted line among Figure 12, see that two in the fingers 70 are positioned under the 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 among 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.Connected orientation from this, by piston element 57 with respect to radially the relatively moving of axis 66, can with piston element 57 from the engaging of buckle member 100 take off.In this moves radially, camming surface 73 on the 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 engage to make elasticity fingers 70 on the opposite side that is positioned at outlet 120 radially to intrinsic deflection, moves radially by exporting 120 with the jerk-finger 70 that allows this deflection.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.
Be in not at fingers 70 under the situation of intrinsic structure of biasing, connecting the process that orientation moves radially forward from shown in Figure 12, fingers 70 begins to deflect into the deflection structure that has different radially expanded ranges with intrinsic structure.From this deflection structure, each fingers 70 is owing to its intrinsic elasticity is biased, thereby turns back to intrinsic structure.From the coupling configuration shown in Figure 12, when beginning radially moves forward, the joint of the forefront of the frustoconical inner surface 110 of sidewall 108 will help radially inwardly to promote fingers 70 at least during piston element 57 begins to move radially.After beginning to move, engage the further deflection that will cause fingers 70 between camming surface 73 on the fingers 70 and the inner edge 138 of camming surface 136, and along with piston element 57 further outwards moves, the camming surface 73 of fingers 70 will lean against on the camming surface 136 and will lean against and be bonded in 120 o'clock on the outer rim 140 of camming surface 136 leaving inlet subsequently.
Outlet 120 is limited by the tank circuit 38, and this tank circuit 38 passes 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 gets at interval enough to be opened, thereby their allow the 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 on the inner end wall 112 is radially spaced enough big distance, thereby they allow bar 61 radially to move forward thus.From being orientated radially connecting shown in Fig. 8, piston element 57 can radially move backward to and connect orientation.In this radially moves inward, being positioned at the camming surface 136 of the sidewall 108 on outlet 120 the either side engages with camming surface 73 on the fingers 70, so that fingers 70 is radially to intrinsic deflection, thereby as seeing among Figure 13, relative fingers 70 radially inwardly arranges fully, makes them can move inward through camming surface 136 and enters in the chamber 102.When piston element 57 moved from the position coaxial of position in this chamber of Figure 13, fingers 70 was owing to its intrinsic elasticity presents the intrinsic structure that it is not setovered.Therefore, in some sense, never connect orientation at piston element 57 and move radially and connect when orientation, fingers 70 deflects into the deflection structure and recovers to present its intrinsic structure rapidly subsequently.
Connecting in the orientation, at first, because the shoulder 74 of fingers 70 engages with the inside face 114 of inner end wall 112, the shoulder of flange 124 surface 126 engages with the upper surface 36 of outer end wall 32 and refer to that 70 camming surface 73 engages with the inside face 110 of sidewall 108, so piston element 57 resistances are from connecting in axial direction mobile of orientation.Connecting in the orientation, resisting piston element 57 moving radially with respect to buckle member 100 by being in the fingers 70 that engages with inside face 110 sidewall 108 under the intrinsic structure.
With reference to figure 8, piston element 57 also can move to and connects orientation by moving to axial from the orientation that axially connects shown in Figure 8.When so moving axially, camming surface 73 on the fingers 70 forms with the side wall surface of inner end wall 112 144 and engages, so that fingers 70 deflects into the deflection structure that has different radially expanded ranges with intrinsic structure from its intrinsic structure of not setovering, 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 moved down by what the side wall surface 144 by inner end wall 112 defined and extend axially inlet.In case the camming surface 73 on the fingers 70 is axially outwards under the inside face 114 that axially outwards points to through inner end wall 112, the fingers that deflects into the deflection structure between the side wall surface 144 of inner end wall 112 when mobile will be replied rapidly to present its intrinsic structure.As seeing among Fig. 9, connecting in the orientation, chamber 102 forms and makes following inside face coaxial and in fact form the keyway portion that is arranged in first surface of revolution that limits around the rotation of axis 66 by corresponding first shape around this axis 66, and described inside face comprises the total inner surface 114 of inner end wall 112, the total inner surface 110 of sidewall 108 and a part of inside face 36 of outer end wall 32.Similarly, when piston component 57 when axis 66 is coaxial, can think that the key portion of outside face of piston element 57 is arranged in second surface of revolution that limits around the rotation of axis 66 by second shape, this second shape and first shape are of similar shape substantially.Provide the corresponding keyway portion of key portion of the outside face of shape and piston element 57 to be considered to help limiting the insertion of piston element in chamber 102 with the rotation shape that drops within the form range that limits by keyway portion for chamber 102.
In this respect, when around the rotation of this axis, can think that the rotation shape of key portion of outside face of piston element 57 is represented a kind of gyro-rotor.Chamber 102 has the inwall in this chamber 102 of abundant qualification, with only when the gyro-rotor of piston element be size, shape and the structure that will be contained in this chamber, promptly 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 the chamber 102.Under the situation in the gyro-rotor of piston element does not drop on the scope of gyro-rotor in this chamber, then refusal uses this piston element.The relative keyway shape in chamber 102 has determined which kind of the concrete rotation shape or the gyro-rotor of the key portion of piston element 57 can be contained in the 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 quality award from the ministry that the key portion of piston element 57 only needs to have permission piston element 57 is selected in the shape that is assembled in the chamber 102 in any rotating part of axis, 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 having fingers 70 (slit 82 separates described fingers) separately, can also replace described fingers with continuous annular element, still, this member will have the elasticity that allows radial deflection to construct to suitable deflection.
The part that is contained in the chamber 102 of waiting 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.Each all passes through under the situation that the plane of revolution around axis 66 rotations limits in the key portion of the keyway portion of buckle member 100 and piston element 57, and piston element 57 can be bonded in the chamber 102 at any relative position around axis 66 rotations.This is preferred, however not necessarily, but various arrangement structures can be provided, so that require piston element 57 suitably to be inserted in the chamber 102, promptly 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 is in and does not radially connect orientation, prepares only to be connected to shell 14 by radially moving backward.From the position shown in Fig. 1, liquid vessel 12 whole beginning levels slide backward the flange 24 that will cause shell 14 and are contained in the tank circuit 52 between the lowermost wall 17 of fluid chamber 16 and the shoulder that is directed upwards towards.Forming member 56 at piston element 57 with respect to piston chamber is positioned under the situation of suitable extended position, piston element 57 and buckle member 100 will be in and radially not connect orientation, radially do not connect orientation from this, 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 and connect orientation to present.
Fig. 4 is carried out reference, and Fig. 4 shows at piston element 57 and is under the situation of complete punctured position, when liquid vessel 12 slides backward the situation that occurs when inserting in the shell 14 by level.The flange 24 of this shell is contained in the tank circuit 52 between the shoulder that is directed upwards towards 53 of lowermost wall 17 and valve module 22.Yet, being at piston element 57 under the situation of punctured position, the fingers 70 of the engagement member 67 of piston element 57 vertically is arranged on the buckle member 100 that is carried by actuator plate 32 axially to connect orientation.From the position of Fig. 4, in first operation of distributing box, promptly by manual shifting bar 31, actuator plate 32 moves straight up from the position that it is positioned under the outer engagement member 67, shown in the arrow among Fig. 4.Buckle member 100 engages with the elasticity fingers 70 of engagement member 67, utilizes this joint, and elasticity fingers 70 allows piston element 57 to enter and be bonded in the buckle member 100, thereby presents coupling configuration radially to intrinsic deflection.
In the process that actuator plate 32 moves up shown in arrow among Fig. 4, buckle member 100 will as far as possible upwards promote piston element 57 when at first engaging with fingers 70, piston element 57 is placed the position of shrinking fully, in this position of shrinking fully, 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 the piston chamber formation member 56 incompatible prevention of joining.
Be under the situation that connects orientation that is connected to actuator plate 32 at piston element 57, in the operating cycle after manual release lever 31, spring 34 will make actuator plate 32 and piston element 57 turn back to extended position together.
Fig. 6 is carried out reference, and Fig. 6 shows elasticity fingers 70 best.In this preferred first embodiment, be provided with six fingers 70, each fingers is all represented the equal segments around the central axis 66 that passes piston element 57, and each fingers all is arranged to by slit 82 evenly spaced apart each other.
Shown in preferred embodiment in, for example, in Fig. 1, piston element 57 is an integral member by the plastic material injection mo(u)lding preferably.After the content of liquid vessel 12 had distributed, this liquid vessel 12 and pump assembly 22 integral body thereof preferably can be used as one unit and abandon.Because usually only wish 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 need have such elasticity, promptly this elasticity allows to connect once with actuator plate 32 or be no more than at least several.Thereby the plastic material of making jerk-finger 70 need not and can deflection repeatedly and still keep its elasticity arbitrarily.Thereby jerk-finger 70 can be formed by relatively inexpensive plastic material, although this material has certain intrinsic elasticity, need not to keep this elasticity in the deflection circulation that repeats.Comprise the piston element 57 of the engagement member 67 that carries jerk-finger 70 or at least its main portion can preferably form basic single-piece element by plastic material, for example form by injection mo(u)lding.
In the embodiment in figure 1, the piston element 57 that piston element 57 allows to move back and forth slides and is inserted in the buckle member 100 on the actuator plate 32, enter as shown in Figure 2 connect orientation or enter as shown in Figure 4 axially connect orientation, do not connect in the orientation at this, piston element can be independent of actuator plate 32 and move.
Connecting in the orientation, the gyroscopic movement of bar 31 moves axially to distribute a certain amount of fluid 18 actuator plate 32 and piston element 57 between the first static extended position and the second complete punctured position.If being at piston element 57, inserts axially not connecting under the situation about being orientated of Fig. 4 by liquid vessel 12, then first of bar 31 move actuator plate 32 is moved with respect to piston element 57, engage and present the orientation of connection of Fig. 2 up to piston element 57 with buckle member 100.By this way, no matter whether piston element 57 inserts in the shell 14 at first to be connected to or not to be connected to actuator plate 32, and distributing box 10 all can be operated in order to distributing fluids 18.
Be distributing fluids 18, actuator 30 is by the gyroscopic movement circulation of bar 31, the gyroscopic movement of bar 31 moves to punctured position with piston element 57 from the first static extended position shown in Fig. 2, discharge this bar 31 then, spring 34 makes actuator plate 32 turn back to the first static extended position to finish this circulation.
Advantageously, distributing box of the present invention 10 allows liquid vessels 12 to insert in the shell need not to guarantee that piston element 57 forms with respect to its piston chamber under the situation that member 56 or actuator plate 32 be in ad-hoc location.

Figure 21 is carried out 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 the buckle member 100 and each in the jerk-finger 57 all are inverted, thereby displaceable element 57 can the orientation that axially do not connect under buckle member 100 upwards move axially to the buckle member 100.Embodiment among Figure 21 still can with Fig. 9 in the similar mode of embodiment move radially between being orientated with not connecting connecting orientation.
Figure 22 is carried out reference, Figure 22 with to Fig. 9 in similar bench section show another embodiment according to buckle member 100 of the present invention and displaceable element 57.In Figure 22, in fact each fingers 70 promptly stretches out all forward, and only extends axially from the support lugn 124 that is arranged on the bar 61 basically.Each fingers 70 all has the camming surface 73 that radially outward points to, and this camming surface 73 can help to make displaceable element 57 to connect orientation from the axis of orientation that axially do not connect on the buckle member 100 to being moved down into.Do not connecting the moving radially of being orientated from connecting to be orientated, the axial outer end of fingers 70 will radially radially be passed through this outlet to intrinsic deflection to allow fingers 70 by the part around its outlet in 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, the outlet of radially opening of passing inner end wall 112 forward should equal the wide diameter between the surface 144 of inner end wall 112, yet outlet will have the diameter that radially reduces along sidewall 108, and the permission that radially moves inward of the far ultraviolet end of feasible finger 70 is radially shifted 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 far-end deflection in axial direction of this disk from bar 61.Disk 67 is depicted as has conical butt camming surface 73 axially outside and that inwardly point to.As seeing best in Figure 23 and Figure 25, the outlet 120 of passing sidewall 108 comprises the exit slot 220 that radially extends 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.Be at piston element 57 under the situation of coupled position as shown in Figure 24, when displaceable element 57 beginning radially when the direction of outlet 120 moves radially, camming surface 73 on the cushion disk(-sc) 67 will with the most preceding lower bond of the lower surface 286 of exit slot 220, cause 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 its outer far-end K/UP thus, thereby mate the curvature of exit slot 220 and thereby allow cushion disk(-sc) 67 radially outward to slip over this slit.Yet, be arranged at displaceable element 57 under the situation of 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 coaxially is fixed in the buckle member 100 to connect orientation.Although it is only shown in Figure 24, but a certain mechanism preferably is set prevents that displaceable element 57 from axially moving up when it engages with member 100, and for the target that realizes that this is preferred but unnecessary, a plurality of elasticity fingers 272 are set, when axially inserting, described a plurality of elasticity fingers 272 can block and have the radially inside buckle face 273 that points to engage with the inside face 114 of inner end wall 112 after process inner end wall 112.
Figure 25 shows the front elevation of the embodiment shown in Figure 23 and Figure 24, but be in part not in the coupling configuration, in this part not in the coupling configuration, displaceable element 57 has moved forwardly in the described outlet, making cushion disk(-sc) 67 be contained in the exit slot 220 also upward deflects at its far-end, thereby the curved configuration that presents the exit slot 220 that passes sidewall 108 is for example when 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 reference, Figure 26 shows and the buckle member 100 that is 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 from the fixed end 302 that is fixed to outer end wall 32 upwards and extend radially inwardly to far-end 304.In these members 370 each all be resilient and deflection radially outward with help 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 that is positioned on outlet 120 the either side is particularly suitable for directly remotely moving each other, and promptly along being moved by the direction shown in the arrow among Figure 26 372, this can help to increase the width that displaceable element 57 can move radially the outlet of passing through 120.But although preferably make any displaceable element 57 carry the member of elastic deflection, 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 fully move to allow displaceable element 57 never to connect orientation and move radially by described outlet.
Figure 28 is carried out 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: form resilient radial and extend disk 67 on bar 61, this disk 67 can be suitable for axially and/or radial deflection.Piston element 57 only is depicted as has cushion disk(-sc) 67, and bar 61 passes this cushion disk(-sc) 67 and extends downwardly into discharge orifice 64.Yet, as shown in the dotted line of Figure 28 shown in the meaning property, the bar 61 of piston element 57 not only extends downwards from disk 67, and extends upward.
In Fig. 6, slit 82 extends axially and passes engagement member 67.By contrast, as shown in Figure 28, slit 84 extends axially axial closing end or closed end 514 from the lower surface 507 that axially outwards points to of engagement member 67 from axial open end 512, and slit 84 is limited between two circumferential isolated sidewalls 516 and 518.Closed end 514 also constitutes the lower surface at top 505.Can see that also slit 84 radially extends to radial closure end or closed end 522 between two circumferential isolated sidewalls 526 and 528 from the radial opening end 530 on the evagination wheel face 508 that radially outward points to.
As seeing in Figure 29, each refers to that 70 annular groove or the slits 308 that also extend by axial and circumferential radially separate with some part of engagement member 67.As in Figure 33, seeing best, slit 308 extends axially axial closing end or closed end 312 from the lower surface 507 that axially outwards points to of engagement member 67 from axial open end 310, 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 the sidewall 320 and 322 is little at pars intermedia 326 places at circumferential end 324 places ratio, so the radial width difference of each slit 308.
The axially extended slit 84 and 308 that is arranged in the circular engagement member 67 helps to realize that the intrinsic structure that elastic component 67 is never setovered deflects into the deflection structure, for example deflect in the process of deflection structure at the intrinsic structure that elastic component is never setovered, isolated sidewall 526 and 528 relative to each other is shifted and/or isolated sidewall 320 and 322 relative to each other is shifted. Slit 84 and 308 provides the thickness that reduces among bridge portion and Figure 38 for the size of bridge portion 85 shown in Figure 33 to reduce bridge portion 309, at described bridge portion place, the distortion of engagement member and bending may easier generations, thereby help engagement member deflection as expected.Compare with the other parts of engagement member, the axial dimension of described bridge portion reduces, and provides this or part that other width reduces can adopt as a kind of method, is used to faying flange that desirable flexibility is provided.
Figure 34 shows at disk 67 to Figure 37 and is in piston element 57 under the situation of identical inflection point, if between as Figure 34 and two arrows 512 shown in Figure 37 and 514, disk 67 is carried out radial compression and/or also along as shown in figure 37 arrow 516 and 518 directions disk 67 is carried out axial compression, described compression acts on respectively on the surface 508 of two radially relative fingers 70, and then disk 67 will present this inflection point.Because cushion disk(-sc) 67 is by elastomeric material, preferably make by elastic body, plastics or rubber, so disk 67 will present Figure 34 to the inflection point shown in Figure 37, refer in 70 two axially inwardly and on the limit radially to intrinsic deflection.Figure 34 has schematically shown the solid line that shows the border between the Different Plane on the upper surface 506, and upper surface 506 can present the state shown in Figure 34 when deflection.These planes 520 are shown to help to make the variation of upper surface 506 when the deflection as seen.
Figure 36 and Figure 37 show best axially upwards and on the limit radially to the finger 70 of intrinsic deflection.
Each refers to that 70 only are attached to piston element 57 effectively by top 505, this top 505 with slit 84 bridge joints between adjacent fingers 70, as shown in Figure 32, and this top 505 with slit 308 bridge joints from fingers 70 between the radially inner downward extension ribs 510 that roughly circumferentially extend, as shown in Figure 33.Can select relative flexibility, size and the thickness of top 505 and fingers 70 to refer to 70 expection deflection capacity to illustrate to strengthen.
