Stopper element 73 in handle 6 (internal surface of housing 6a) with can towards rotational axis x, namely can configure along the mode of the direction movement orthogonal with spin axis X.Stopper element 73 is arranged on the guiding such as the rib in handle 6, and is exerted a force towards spin axis X by spring 48 all the time, is connected to the stop position adjusting portion 722 (stopping abutment 724) of rotation coupling member 72 and is located by its forward end.Therefore, stopper element 73 utilizes the rotation of the rotation coupling member 72 caused by the rotary manipulation of bar component 71 (movement of stop position adjusting portion 722) and retreats along the direction orthogonal with spin axis X mobile.
Stopper element 73 has for supplying the bar abutting part 731 abutted by the jut 412 of the solar term bar 41 after rotating operation.Outstanding jut 412 side be formed in by solar term bar 41 of bar abutting part 731, it has highly different multiple (be two at this) bar bearing surface (the 1st bar bearing surface 731a, the 2nd bar bearing surface 731b) (with reference to Fig. 5).
Bar abutting part 731 is configured to, and when stopper element 73 moves from the retreating position shown in Fig. 5 towards spin axis X, this bar abutting part 731 is positioned on the motion track of the movement caused by the rotation of solar term bar 41 of the jut 412 of solar term bar 41.And if the 1st bar bearing surface 731a or the 2nd bar bearing surface 731b is positioned on the motion track of jut 412 of solar term bar 41, then when solar term bar 41 have rotated prearranging quatity, its jut 412 is connected to the 1st bar bearing surface 731a or the 2nd bar bearing surface 731b.Thus, solar term bar 41 is prevented from (restriction) further rotation.
Then, the effect of limting mechanism 70 is described with reference to Fig. 9 A ~ Fig. 9 D, Figure 10 A ~ Figure 10 D and Figure 11 A ~ Figure 11 D.
Fig. 9 A ~ Fig. 9 D indication rod component 71 is in state during described normal position.The F portion enlarged view of Fig. 9 A is the figure corresponding with Fig. 5, Fig. 9 B to be the figure corresponding with Fig. 7, Fig. 9 C be Fig. 9 A, Fig. 9 D is the G portion enlarged view of Fig. 9 A.
As described above, when bar component 71 is in described normal position (with reference to Fig. 9 A), rotate the locking recess 723b of the engaging portion 721 of coupling member 72 engaging in the engaging protuberance 47 (with reference to Fig. 9 C) be configured in handle 6.In addition, stopper element 73 is connected to the 1st stop bearing surface 724a (with reference to Fig. 9 D) of the stop position adjusting portion 722 of rotating coupling member 72.In this condition, stopper element 73 is in described retreating position, namely from rotational axis x position farthest, the bar abutting part 731 of stopper element 73 is not positioned on the described motion track of the jut 412 of solar term bar 41.
Therefore, even if solar term bar 41 is by rotating operation, the jut 412 of solar term bar 41 also can not be connected to the bar abutting part 731 of stopper element 73.That is, the slewing area of solar term bar 41 is not stopped component 73 and limits.Thus, closure THV by solar term bar 41 from described initial rotation position rotating operation to maximum rotated position (with reference to Fig. 9 A), can be set to standard-sized sheet, be set to maximum opening by the aperture of closure THV by operating personnel.
Figure 10 A ~ Figure 10 D indication rod component 71 is by the state from described normal position to arrow D direction rotating operation during prearranging quatity.The H portion enlarged view of Figure 10 A is the figure corresponding with Fig. 5, Figure 10 B to be the figure corresponding with Fig. 7, Figure 10 C be Figure 10 A, Figure 10 D is the I portion enlarged view of Figure 10 A.
Bar component 71 by from described normal position to arrow D direction rotating operation time, rotate the locking recess 723c of the engaging portion 721 of coupling member 72 engaging in the engaging protuberance 47 be configured in handle 6 (with reference to Figure 10 C).In addition, stopper element 73 utilizes the movement of the stop position adjusting portion 722 caused by the rotation of rotating coupling member 72 and moves towards rotational axis x, is connected to the 2nd stop bearing surface 724b (with reference to Figure 10 D) of the stop position adjusting portion 722 of the rotation coupling member 72 after rotation.Thus, the 1st bar bearing surface 731a of the bar abutting part 731 of stopper element 73 is positioned on the described motion track of the jut 412 of solar term bar 41.
Therefore, when operating personnel's rotating operation solar term bar 41, the jut 412 of solar term bar 41 is connected to the 1st bar bearing surface 731a of stopper element 73 (with reference to Figure 10 D), and solar term bar 41 has been prevented from further rotation.Thus, operating personnel is merely able to solar term bar 41 rotating operation to be connected to the position of stopper element 73 (the 1st bar bearing surface 731a), the 1st middle turning position (with reference to Figure 10 A) namely between described initial rotation position and described maximum rotated position to the jut 412 of solar term bar 41.That is, the aperture of closure THV is limited in below the aperture corresponding to described 1st middle turning position.In other words, solar term bar 41 by full-helm operate time the aperture of closure THV become the aperture corresponding to described 1st middle turning position.
Figure 11 A ~ Figure 11 D indication rod component 71 by from the state shown in Figure 10 A ~ Figure 10 D further to state during arrow D direction rotating operation.The J portion enlarged view of Figure 11 A is the figure corresponding with Fig. 5, Figure 11 B to be the figure corresponding with Fig. 7, Figure 11 C be Figure 11 A, Figure 11 D is the K portion enlarged view of Figure 11 A.
Bar component 71 by from the state shown in Figure 10 A ~ Figure 10 D further to arrow D direction rotating operation time, rotate the locking recess 723d of the engaging portion 721 of coupling member 72 engaging in the engaging protuberance 47 be configured in handle 6 (with reference to Figure 11 C).In addition, stopper element 73 utilizes the movement of the stop position adjusting portion 722 caused by the rotation of rotating coupling member 72 and towards rotational axis x movement further, is connected to the outer circumferential face (with reference to Figure 11 D) of the standard shaft portion 72a of the rotation coupling member 72 after rotation.Thus, the 2nd bar bearing surface 731b of the bar abutting part 731 of stopper element 73 is positioned on the described motion track of the jut 412 of solar term bar 41.
Therefore, when operating personnel's rotating operation solar term bar 41, the jut 412 of solar term bar 41 is connected to the 2nd bar bearing surface 731b of stopper element 73 (with reference to Figure 11 D), and solar term bar 41 has been prevented from further rotation.Thus, operating personnel is merely able to solar term bar 41 rotating operation to be connected to the 2nd middle turning position (with reference to Figure 11 A) between position, the i.e. described initial rotation position of stopper element 73 and described 1st middle turning position to the jut 412 of solar term bar 41.That is, the aperture of closure THV is limited in below the aperture corresponding to described 2nd middle turning position (being less than the aperture corresponding with described 1st middle turning position).In other words, solar term bar 41 by full-helm operate time the aperture of closure THV become the aperture corresponding to described 2nd middle turning position.
In addition, by the bar component 71 after from described normal position to arrow D direction rotating operation by when returning described entopic direction rotating operation, stopper element 73 is pushed by the stop position adjusting portion 722 of rotating coupling member 72 and moves to the direction away from rotational axis x.Thus, limting mechanism 70 is back to the state shown in the state shown in Figure 10 A ~ Figure 10 D or Fig. 9 A ~ Fig. 9 D from the state shown in Figure 11 A ~ Figure 11 D or is back to the state shown in Fig. 9 A ~ Fig. 9 D from the state shown in Figure 10 A ~ Figure 10 D.
Thus, operating personnel limits the slewing area of solar term bar 41 by the bar component 71 of rotating operation limting mechanism 70, thereby, it is possible to full-helm operate solar term bar 41 time the aperture of closure THV is set to middle aperture between described minimum aperture and described maximum opening.Therefore, even if operating personnel when the aperture of closure THV being remained middle aperture be also full-helm operate solar term bar 42, easily the aperture of closure THV is remained middle aperture.In addition, because the relation between the rotating operation amount of solar term bar 41 and the aperture of closure THV is because whether bar component 71 is by rotating operation, the slewing area namely whether limiting solar term bar 41 and changing, therefore, even if under the state of slewing area limiting solar term bar 41, also easily utilize the rotating operation of solar term bar 41 to adjust the aperture of closure THV.
(the 2nd mode of execution)
Then, the 2nd mode of execution of described throttle operation device is described.
Figure 12 is the figure of the structure of the 2nd mode of execution for illustration of described throttle operation device, represents the internal structure of handle 6.In addition, use identical reference character to the key element general with the 1st mode of execution, the description thereof is omitted as appropriate.

Same with the regulating mechanism 60 of the 1st mode of execution, regulating mechanism 80 makes the solar term bar side end 421a of outer tube 421 move along the length direction of inner bracing wire 422, thus, adjusts the tractive degree of inner bracing wire 422.Regulating mechanism 80 also has: adjustment screw member 81, and it is by operating personnel's rotary manipulation; And pipe retaining member 82, it is for the solar term bar side end 421a of fixing maintenance outer tube 421.
Adjustment screw member 81 with its axis along the length direction of inner bracing wire 422 mode, be namely configured in abreast in handle 6 with the length direction of inner bracing wire 422.Form porose or groove at the head of adjustment screw member 81, this hole or groove can insert for the fore-end of the instrument (hexagon wrench, a word screwdriver etc.) for making adjustment screw member 81 rotate.Handle 6 is formed for run through for described instrument, the penetration hole 52 that extends abreast with the length direction of inner bracing wire 422.In the present embodiment, the cardinal extremity part be connected with ajutage 5 of handle 6 is positioned at the outside of ajutage 5, divides be formed with penetration hole 52 at the base end part of this handle 6.
Pipe retaining member 82 is can be disposed in handle 6 along the mode of the length direction movement of inner bracing wire 422.Pipe retaining member 82 has the internal thread part 821 be screwed with adjustment screw member 81.At this, the nut utilizing press-in etc. to be arranged on pipe retaining member 82 forms internal thread part 821.And, be configured to when adjusting screw member 81 and rotating pipe retaining member 82 and move along the length direction of inner bracing wire 422.
In this mobile mechanism 80, when adjusting screw member 81 and rotating to the 1st direction, pipe retaining member 82 moves along the length direction of inner bracing wire 422 to the direction close to solar term bar 41.Thus, the solar term bar side end 421a of outer tube 421 is to the position after moving close to the direction of solar term bar 41, the direction of namely loosening the tractive of inner bracing wire 422 and remain on.
On the other hand, when adjusting screw member 81 and rotating to the 2nd direction contrary with described 1st direction, pipe retaining member 82 moves along the length direction of inner bracing wire 422 to the direction away from solar term bar 41.Thus, the solar term bar side end 421a of outer tube 421 is to the position after moving away from the direction of solar term bar 41, the direction that namely strengthens the tractive of inner bracing wire 422 and remain on.
Thus, operating personnel, by the adjustment screw member 81 of rotary manipulation regulating mechanism 80 as required, can make the solar term bar side end 421a of outer tube 421 move along the length direction of inner bracing wire 422 and adjust the tractive degree of inner bracing wire 422.Specifically, operating personnel, by making described instrument through the penetration hole 52 be formed on handle 6, namely suitably making adjustment screw member 81 rotate close to adjusting screw member 81 abreast with the length direction of inner bracing wire 422, can adjust the tractive degree of inner bracing wire 422.
In addition, for regulating mechanism 80, Figure 12 represents that the solar term bar side end 421a of outer tube 421 is in the state from the nearest position of solar term bar 41, and Figure 13 represents that the solar term bar side end 421a of outer tube 421 is in the state from solar term bar 41 position farthest.
Then, the structure of limting mechanism 90 is described with reference to Figure 14 ~ Figure 17.
The L-L amplification view of Figure 14 to be the major component figure of Figure 12, Figure 15 be Figure 14, Figure 16 be represent from the unilateral observation contrary with Figure 14 to the figure of outward appearance of handle 6, Figure 17 is the M-M amplification view of Figure 14.
As shown in Figure 14 ~ Figure 17, limting mechanism 90 comprises: bar component 91, and it is by operating personnel's rotating operation; Rotate coupling member 92, itself and bar component 91 link; And stopper element 93, it links with rotation coupling member 92 and moves.And limting mechanism 90 is configured to, when solar term bar 41 have rotated prearranging quatity, be connected to stopper element 93 by the jut 412 be formed on solar term bar 41 and stop solar term bar 41 to rotate further.
Bar component 91 is disposed on the outer surface of handle 6 (housing 6a), its by operating personnel from normal position (state shown in Figure 16) to arrow D direction and arrow E direction rotating operation.Rotate coupling member 92 to be configured in handle 6 than the side (with reference to Figure 15) of solar term bar 41 close to the inner bottom surface of handle 6 (housing 6a).Bar component 91 and rotation coupling member 92 link integratedly, be configured to by rotating operation bar component 91 and rotation coupling member 92 is also rotated.
As shown in figure 15, bar component 91 is inserted into the corresponding recess 92b on the standard shaft portion 92a being formed in rotation coupling member 92 with rotation coupling member 92 by the protuberance 91a being formed in polygon-shaped (such as hexagon shape) on bar component 91 and is prevented from mutual relative rotation.And the bolt 94 of through bar component 91 and the band spring washer that rotates coupling member 92 inserts from bar component 91 side, and be embedded in rotate coupling member 92 standard shaft portion 92a in internal thread part 92c be screwed.Thus, bar component 91 is arranged on handle 6 under the state linked in the mode of rotating integratedly around the rotational axis x identical with solar term bar 41 with rotation coupling member 92.In addition, be provided with cylindrical part 92d in the side contrary with bar component 91 side of rotating coupling member 92, this cylindrical part 92d contains the outer circumferential face being inserted with the Cylindorical rod portion 41a in described axle portion in inside of solar term bar 41 in the mode that solar term bar 41 can rotate.

Stopper element 93 is formed as the arc-shaped centered by rotational axis x, its at handle 6 can arrange with the mode of rotational axis x movement abreast.Specifically, the two end part of stopper element 93 utilize erect be arranged on guide portion 53a, 53b in handle 6 can be kept with the mode of rotational axis x movement abreast, be in other words can be kept (with reference to Figure 14, Figure 15) to the direction of the inner bottom surface away from handle 6 (housing 6a) with close to the mode of the direction movement of the inner bottom surface of this handle 6 (housing 6a).
In addition, as shown in figure 17, stopper element 93 is formed with the bullport 931 run through for the leading axle portion 923 rotating coupling member 92.Bullport 931 has: elongated hole portion 931a, and it extends along the sense of rotation of rotating coupling member 92; And slope hole portion 931b, its from elongated hole portion 931a relative to rotate coupling member 92 inner bottom surface from sense of rotation to handle 6 (housing 6a) roll tiltedly extend.Therefore, when causing the leading axle portion 923 rotating coupling member 92 to move by the rotation of rotating coupling member 92, stopper element 93 utilizes the slope hole portion 931b of bullport 931 and moves abreast with rotational axis x.
In addition, stopper element 93 has for supplying the bar abutting part 932 abutted by the jut 412 of the solar term bar 41 after rotating operation.Bar abutting part 932 is outstanding to be formed on the face of rotational axis x side of stopper element 93, and it has for that abutted by the jut 412 of the solar term bar 41 after rotating operation, highly different multiple (be two at this) bar bearing surface (the 1st bar bearing surface 932a, the 2nd bar bearing surface 932b).
Bar abutting part 932 is configured to, when stopper element 93 moves with spin axis X abreast from the retreating position shown in Figure 15, Figure 17, specifically when stopper element 93 moves to the direction of the inner bottom surface away from handle 6, this bar abutting part 932 is positioned on the motion track of the movement caused by the rotation of solar term bar 41 of the jut 412 of solar term bar 41.And, if the 1st bar bearing surface 932a of bar abutting part 932 or the 2nd bar bearing surface 932b is positioned on the described motion track of the jut 412 of solar term bar 41, then when solar term bar 41 have rotated prearranging quatity, the jut 412 of solar term bar 41 is connected to the 1st bar bearing surface 932a or the 2nd bar bearing surface 932b.Thus, solar term bar 41 is prevented from (restriction) further rotation.
Then, the effect of limting mechanism 90 is described with reference to Figure 18 A ~ Figure 18 E, Figure 19 A ~ Figure 19 E and Figure 20 A ~ Figure 20 E.
