Main body fixation is interrupted on ring 230, the torque spring region wound round about being arranged after the fixed ring 230 of main body
Not by torsional deformation, therefore can be set including by the fixed more than two Rotary Districts distinguished centered on ring of the main body
The torque spring in domain can also be for opposite direction (reversed) so as to be directed to the torsional deformation of a direction (forward direction)
Torsional deformation plays buffer function.
It is different from the prior art observed in Fig. 1 and Fig. 2, in the case where being not provided with other gap, by torque spring
200 one end 210 and the other end 220 are secured entirely in the state of the guide rod 120, can also carry out rotating in the forward direction and instead
To rotation.The durability for being equipped with the valve of torque spring 200 can be improved as a result,.
In addition, the torque spring, which can use to spring that a direction is formed, executes rotating forward or reversion,
The fixed ring of the main body has to be constituted horizontal or inclined shape relative to the torque spring and protrude extended structure,
To be characterized in that, the operating effect of rotating forward or reversion above-mentioned can be solved by the improvement in simple structure.
Hereinafter, carrying out more specific explanation to the structure of fixed part 130 referring to Fig. 5.
The fixed part 130 that there is the inside of shell alternatively formed to be formed with distinguishing with the rotation gear 100 can be with
It is formed in the form to connect with the outer peripheral edge of the torque spring 200.It will be formed in the torque spring 200 of rotation gear
Main body fixation is attached to fixed part 130 with ring 230 and is fixed, one end 210 without being attached to fixed torque spring 200
Or the guide rod 120 of the other end 220, thus on the basis of the fixed ring of the main body of torque spring 200, due to winding side
To different structures, thus bidirectional rotation can be carried out.
In addition, according to circumstances, for the aperture to each rotating forward or the reversion that execute the EGR valve for rotating forward or inverting
Angle is controlled, and main body fixation of the invention may be configured as with ring from the whole height half for being equivalent to the torque spring
Height to both set a distances apart from top to bottom.It means that the height of ring 230 can be used as target according to main body fixation will be provided with
Rotating forward or reversion valve opening angle, set adjusting in the enterprising line position of the whole height of the torque spring.
Referring to Fig. 6, shows the main body fixation compared with Fig. 4 and use ring 230 in the height of whole torque spring to lower side
It, can be when adjusting the valve opening angle of desired target rotated and reverse according to setting to the apperance for carrying out position adjusting
It counts pattern and carries out free adjusting.
For example, if by means of by the main body it is fixed be formed in centered on ring 230 main body fix it is upper with ring
The rotating forward of the direction of rotation induction EGR valve of the rotation gear and rotary shaft of the coiling direction of the torque spring of side, then with main body
The compressed per unit length that the main body fixes the torque spring of upside with ring is formed in centered on fixed ring 230
Torque is less than by the fixed quilt for being formed in the main body centered on ring 230 and fixing the torque spring of downside with ring of main body
The torque of the per unit length of compression, therefore caused by forward direction corresponding with the torque of same size generated from motor
Valve opening amount is designed big compared with reversed caused valve opening amount.
In contrast, if by means of by the main body it is fixed be formed in the main body centered on ring 230 and fix use ring
Upside torque spring coiling direction rotation gear and rotary shaft direction of rotation induction EGR valve reversion, then instead
To can be designed big compared with caused valve opening amount valve opening amount caused by the forward direction.
It can also be carried out according to the main body is fixed with the change of the design height of ring 130 as described in the foregoing
Control.
