Tapered configuration 127 and 120 junction of shell).When fluid is incompressible and under a steady flow condition, maximum cross-section is flowed through
The product of the flow velocity V1 and maximum secting area A1 of the fluid of product A1 can be equal to the fluid one stream for flowing through minimum sectional area A2
The product of fast V2 and minimum sectional area A2, that is, A1*V1=A2*V2.Since maximum secting area A1 is more than minimum sectional area A2,
Therefore it can learn that flow velocity V2 can be more than flow velocity V1.When the fluid that the first conduit 126 is delivered to by groove body 114 flow velocity V1 compared with
When slow, the flow velocity V2 for the fluid for flowing into accommodating chamber 122 may make to accelerate by the design of tapered configuration 127,129 so that stream
Body still can effectively drive rotating member 124 to rotate.
Rotating member 124 may be provided with the flabellum 130 of four protrusions, and the angle between adjacent four flabellums 130 is equal and will
Rotating member 124 divides for four sector regions.However, the quantity of flabellum 130 also can be 2,3 or 4 or more.Furthermore it rotates
Part 124 is in being formed with a trepanning 132 on one of four sector regions region so that light can be by rotating member 124
Side is across trepanning 132 and the other side for the rotating member 124 that arrives.However, also can be in one tool of setting in the trepanning 132 of rotating member 124
The transmittance section 134 for having light-transmitting materials, is passed through with sharp light.
Aforementioned light sensing unit 136 is set near ontology 118, and it includes one first optical transceiver modules 137 and one
Two optical transceiver modules 138, and the first, second optical transceiver module 137,138 is that this is set in a manner of being asymmetric with central shaft C
118 both sides of body, for example, the first optical transceiver module 137 in this embodiment is provided in rotating member 124 in 3A figures
The opposite side of lower-left sector region, and the bottom right sector region that the second optical transceiver module 138 is provided in rotating member 124 is opposite
Side.Wherein, the first optical transceiver module 137 includes one first optical transmitting set 137T and one first optical receiver 137R, and the second light is received
Send out module 138 include one second optical transmitting set 138T and one second optical receiver 138R, and the first, second optical receiver 137R,
138R receiving the transmittance section sent out from first, second optical transmitting set 137T, 138T and in the trepanning 132 respectively
134 the first, second light.
A to Fig. 4 D is please referred to Fig.4, Fig. 4 A to Fig. 4 D are that the rotating member 124 of one embodiment of the invention turns to different location
Schematic diagram.Assume initially that rotating member 124 velocity of rotation be constant speed and in time t=0 position the position shown in Fig. 4 A,
It is exactly the sector region that transmittance section 134 corresponds to lower right, the second optical receiver 138R of the second optical transceiver module 138 can at this time
Receive the second light being sent out from the second optical transmitting set 138T and across transmittance section 134.Then rotating member 124 is with inverse
Clockwise turns to the position of Fig. 4 B in time t=T so that and transmittance section 134 is located at the sector region in upper right side, and at this time
One optical receiver 137R and the second optical receiver 138R can not all be received from the first optical transmitting set 137T and the second light hair
The optical signal of emitter 138T.The position of Fig. 4 C can be turned in time t=2T followed by rotating member 124, and in time t=3T
When turn to the position of Fig. 4 D, at this time transmittance section 134 corresponds to the sector region of lower left, and the first optical transceiver module 137

The time point of above-mentioned signal is received to judge the rotation direction of rotating member 124.For example above-mentioned, when rotating member 124 is by
When the position of 4D figures turns to the position of Fig. 4 A, processing unit 106 can learn that the first optical transceiver module 137 is receiving first
After light, the second light is received by the second optical transceiver module 138 after time T.And then when rotating member 124 is again by scheming
When the position of 4A turns to the position of Fig. 4 D, processing unit 106 can learn that the second optical transceiver module 138 is receiving two light
After must be after time 3T, the first optical transceiver module 137 just will receive first light, therefore processing unit 106 can basis
Signal intensity during this learns that rotating member 124 is to rotate in a counter-clockwise direction.If on the contrary, the first optical transceiver module 137
After receiving the first light, the second optical transceiver module 138 just receives the second light after time 3T.Or second light receive and dispatch mould
After block 138 receives after the second light merely through time T, the first optical transceiver module 137 is received by the first light, then handles list
Member 106 can judge that rotating member 124 is to be rotated clockwise.
