Insertion hole, be formed at the position of the center of rotation of the separate switching gag lever post 51 of the first plate portion 51A switching part 511 and supply
The hole portion 513 of support shaft SS1 insertion, wherein switching part 511 is from the first plate portion 51A towards the direction Z1 cam part outstanding, hole
The first plate portion 51A is run through along Z-direction in portion 513, at the position of the center of rotation of the separate switching gag lever post 51 of the second plate portion 51B
It is formed with limiting section 512 and protrusion 514, wherein limiting section 512 is made of the outer peripheral surface of the second plate portion 51B, protrusion 514
It is prominent from the second plate portion 51B towards the direction Z1, and it is inserted in the limit groove portion formed on rotating output member 6, thus rotating
Output link 6 rotates switching gag lever post 51 with rotatable output component 6, also, 514 shape of limiting section 512 and protrusion
At at the different location of the second plate portion 51B, limiting section 512 when spool 8 is indexed to operating position with the plate-like of driving wheel 32
Portion 323 abuts to limit driving wheel 32 and reverse.
Also, force application part 52 is the compression helical spring being arranged between castle wheel 31 and driving wheel 32.
<The structure of rotatable output component and pull parts>
As shown in Figure 1, rotating output member 6 is including gear part 61 and with wheel portion 62, wherein gear part 61 for example passed through
It crosses gear TG and is engaged with pinion part 3411 possessed by the axle portion of pinion frame 34 341, the periphery with wheel portion 62 is formed
There is the accommodating groove stored for pull parts 7.
Pull parts 7 are wire rods, and one end of pull parts 7 is for example locking with rotating output member 6, pull parts 7 it is another
One end is connect with spool 8.
<The work of discharge valve controller>
In the state that spool 8 is located at initial position, the switching part 511 of switching gag lever post 51 makes driving wheel 32 overcome force
The active force of component 52 and engaged with castle wheel 31.
In the above-described state, when powering to motor 2, the driving force of motor 2 is for example transferred to connection via transition gear etc.
It moves the first part of part 41 and makes first part's high speed rotation, thereby, second part is followed because of electromagnetic action to be rotated, thus
Braked wheel 421 is driven to rotate, so that the braking parts 4212 of braked wheel 421 are contacted with control sheet 4221 (at this point, first part becomes
Idling conditions), prevent transition member 422 from rotating, so that the gear ring 35 of output clutch 3 be prevented to rotate.
On the other hand, the driving force of motor 2 is transferred to driving wheel 32 via castle wheel 31, is then transferred to and driving wheel 32
The planetary gear 33 that engages of sun gear portion 321, at this point, since the rotation of gear ring 35 of output clutch 3 is prevented from, because
The rotation of this pinion frame 34, so that the transition gear TG rotation engaged with the pinion part 3411 of pinion frame 34 is driven,
It drives the rotating output member 6 engaged with transition gear TG to rotate in turn, pulls on component 7 and be wound in rotating output member 6
Band wheel portion 62 makes the driving of spool 8 be indexed to operating position, valve is opened.
Spool 8 driving be indexed to operating position when, switching gag lever post 51 switching part 511 make driving wheel 32 from clutch
The position of 31 engagement of wheel is indexed to the position isolated with castle wheel 32, and thereby, the driving force of motor 2 is no longer transferred to spool 8.
On the other hand, when the driving of spool 8 is indexed to operating position, the locking piece 3232 of limiting section 512 and driving wheel 32
It abuts and limits the reverse of driving wheel 32, also, the driving force of motor 2 continues the first part for being transferred to linkage part 41, second
Part is acted on by magnetic induction force, so that the continuation of braking parts 4212 of braked wheel 421 is contacted with control sheet 4221, prevents transition part
Part 422 rotates, so that the gear ring 35 of output clutch 3 be prevented to rotate, thereby, can lock pinion frame 34, make spool
8, pull parts 7 and rotatable output component 6 are maintained at state when spool 8 is in operating position.
In addition, the reset force that spool 8 has by itself starts to do to initial position and resets when stopping powering to motor 2
Movement, at this point, the first part of linkage part 41 stops rotating, the magnetic induction force between first part and second part disappears,
Therefore, under the action of the elasticity recovery part of brake portion 42, braked wheel 421 releases constraint to transition member 422, export from
The gear ring 35 for closing mechanism 3 becomes rotatable state, and thereby, spool 8 returns to initial bit under the action of above-mentioned reset force
It sets, valve becomes closed state.
