<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 overcomes transition wheel portion 312
The active force of force application part 52 and engaged with castle wheel 311.
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.
The first part of motivation structure 41 and make first part's high speed rotation, thereby, second part is followed because of magnetic induction to be rotated, thus band
Dynamic brake component 421 rotates, so that the holding section 42131 of brake component 421 and the engaged part 42211 of transition member 422 connect
Touching (at this point, first part becomes idling conditions), prevents transition member 422 from rotating, to prevent the gear ring of output clutch 3
324 rotations.
On the other hand, the driving force of motor 2 is transferred to transition wheel portion 312 via castle wheel 311, is then transferred to and fixed star
The planetary gear 322 that gear part 321 engages, at this point, since the rotation of the gear ring 324 of output clutch 3 is prevented from, because of this journey
Gear rack 323 rotates, so that the transition gear TG rotation engaged with the pinion part 32311 of pinion frame 323 is driven, into

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 transition wheel portion 312 from
The position that castle wheel 311 engages is indexed to the position isolated with castle wheel 32, and thereby, the driving force of motor 2 is no longer transferred to valve
Core 8.
On the other hand, when the driving of spool 8 is indexed to operating position, the locking piece of limiting section 512 and transition wheel portion 312
31222 abut and limit the reverse of transition wheel portion 312, also, the driving force of motor 2 continues first that is transferred to linkage mechanism 41
Point, second part is acted on by magnetic induction force, so that the holding section 42131 of brake component 421 continues to connect with engaged part 42211
Touching prevents transition member 422 from rotating, so that the gear ring 324 of output clutch 3 is prevented to rotate, it thereby, can be by pinion frame
323 lockings, make spool 8, pull parts 7 and rotatable output component 6 be 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 mechanism 41 stops rotating, the magnetic induction force between first part and second part disappears,
Therefore, under the action of elasticity recovery part 423 of arrestment mechanism 42, brake component 421 releases the constraint to transition member 422,
The gear ring 324 for exporting clutch 3 becomes rotatable state, and thereby, spool 8 returns under the action of above-mentioned reset force
Initial position, valve become closed state.
