Fig. 1 is the structural representation of the first embodiment of electric flow distributor mechanism of the present invention, Fig. 2 is the schematic diagram of the guiding valve of electric flow distributor mechanism shown in Figure 1, Fig. 3 is the local enlarged diagram of the detent mechanism of electric flow distributor mechanism shown in Figure 1, Fig. 4 is a kind of schematic diagram of structure of the spacer of electric flow distributor mechanism shown in Figure 1, Fig. 4 a is the A-A view of spacer shown in Figure 4, and Fig. 4 b is the B-B view of spacer shown in Figure 4.As shown in the figure, this electric flow distributor mechanism comprises a shell 109 and a base member, base member comprise base 105, base plate 102 and be arranged on base 105 and base plate 102 between spacer 112, valve pocket 110 of shell 109 and the common formation of base member, the some of base 105 and base plate 102, spacer 112 are fixed in the described valve pocket; The shell 109 outer coil components 111 that are fixed with as the step motor stator part, also be provided with magnetic rotor component 107 as stepper motor mover part in the shell, under magnetic rotor component 107 drives, can come power transmission shaft 108, and the guiding valve 106 that rotates with magnetic rotor component and power transmission shaft of back rotation, guiding valve 106 is oppositely arranged and is fixed on along on the axial location of power transmission shaft with base plate 102, and power transmission shaft 108 is fixed-type together during by the magnetic rotor component injection mo(u)lding.
Like this, valve pocket is interior is fixed part with regard to having formed a part of fixing and can not rotate: comprise base member and shell, this partly can not rotate; A part of in addition is exactly the rotatable parts that can rotate under magnetic rotor component drives: comprise the axle sleeve that magnetic rotor component, power transmission shaft, guiding valve and power transmission shaft are fixing.In order to guarantee the even, stable of assignment of traffic between a plurality of outlets, magnetic rotor component can drive power transmission shaft carry out a direction continuous not constant speed rotation or carry out constant speed and rotate certain hour, pause certain hour, certainly this electric flow distributor mechanism also can come back rotation, but under a plurality of export situations, the rotation of carrying out a direction recently back rotation to assignment of traffic stable and uniform more.For this reason, this electric flow distributor mechanism in valve pocket fixed part and rotatable parts between be provided with a detent mechanism, this detent mechanism is arranged between the fixed parts such as the rotatable parts such as magnetic rotor component, power transmission shaft, guiding valve and base member, shell, particularly, that a keeper and location division are set respectively on fixed part and rotatable parts, when rotatable parts rotate to a direction, detent mechanism is inoperative, thereby rotatable parts can rotate the distribution of a plurality of outlets being carried out flow always continuously for this reason; And when rotating round about, then when keeper contacts with the location division and rotatable parts are stopped operating and realize the location, like this, in system owing to step-out in the cumulative errors that produce for a long time or the running, leapfrog, and system shake the position deviation that causes and all can solve by the location of detent mechanism, can or be arranged to particularly to carry out one-time positioning every certain time interval when system boot and guarantee the particularly accuracy of the position between the exit position of the rotatable parts such as magnetic rotor component, power transmission shaft, guiding valve and base member.
In the present embodiment, keeper 112a is arranged on the spacer 112, and keeper 112a comprises a guide part 112a1 and a stop part 112a2, and stop part 112a2 is a blocking surface, and guide part 112a1 is the smooth transition face of a tape guide effect.The below of keeper 112 also has a 112b of wall section in addition, and so relative bottom surface keeper 112a just has a good elasticity diametrically, and in rotation direction, then there is not elasticity in keeper.When guiding valve 106 rotated with magnetic rotor component, keeper 112a just was attached to the radially position of the periphery of guiding valve 106.The location division is a location division 106c who is arranged on the guiding valve 106, and similarly, location division 106c also comprises a guide part 106c1 and a stop part 106c2, and stop part 106c2 is a blocking surface, and guide part 106c1 is the guide surface of a smooth transition.At magnetic rotor component drive power transmission shaft 108, when guiding valve 106 clockwise directions rotate and namely rotate such as figure arrow A direction, owing to do not have conflict between the guide part 112a1 of keeper 112a and the guide part 106c1 of location division 106c, guiding valve 106 still can be rotated further under magnetic rotor component 107 drives for this reason, simultaneously because the wall section on the spacer 112, make the friction between keeper and the guiding valve periphery less, therefore the rotation of guiding valve do not affected; And when namely rotating such as figure arrow B direction in the counterclockwise direction, existence conflict and can't being rotated further again between the stop part 112a2 of keeper 112a and the stop part 106c2 of location division 106c, thereby the location between realization rotatable parts and the fixed part.
