Abstract
The invention discloses a sensitive driver for a bypass valve of a turbocharger. The sensitive driver comprises a housing, a diaphragm, a piston, a fan and a push bar. The diaphragm is mounted inside the housing and divides the housing into a pressure cavity and a piston cavity. The piston is disposed inside the piston cavity and tightly attached to the bottom of the diaphragm. A spring is arranged inside the piston and sleeves the push bar. The fan is disposed inside the pressure cavity. One end of the push bar penetrates the piston and is fixedly connected with the fan; the other end of the push bar penetrates the housing and is connected to an external device. An intake tube is fixed to the upper surface of the housing and is communicated with the pressure cavity. In this case, the sensitive driver allows the turbocharger to be driven more sensitively and is simple and reliable in structure.

Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of sensitive-type turbocharger bypass driver, comprise: actuator housing 1, diaphragm 2, piston 3, fan 4 and catch bar 10, described diaphragm 2 is arranged on described actuator housing 1 inside, and the inner chamber of actuator housing 1 is divided into pressure chamber 6 and piston cavity 7, described piston 3 is arranged in described piston cavity 7, and be close to described diaphragm 2 belows, described piston 3 inside are provided with spring 5, described spring 5 is sleeved on described catch bar 10, described fan 4 is arranged in described pressure chamber 6, one end of described catch bar 10 penetrates described piston 3 and is fixedly connected with described fan 4, the other end passes described actuator housing 1 and is connected in external device, described actuator housing 1 side, top is fixed with suction tude 11, described suction tude 11 and described pressure chamber 6 are communicated with.
Described suction tude 11 is fixedly connected with by the mode of stamping riveting with described actuator housing 1, can improve riveting intensity by the mode of stamping riveting, thereby improves working life.
In described actuator housing 1, between the bottom surface of piston cavity 7 and the spring 5 of described piston 3 inside, be provided with protecting cover 8.
The lower surface indent of described protecting cover 8, and form circular draw-in groove 12 with the bottom surface of described piston cavity 7, by being provided with after protecting cover 8, can effectively reduce the damage of spring 5 and actuator housing 1, further improve working life.
Described actuator housing 1 is provided with seal ring 9 with the joint of described catch bar 10.
The sealing lip that is provided with the shape that is convexly curved in the middle of described seal ring 9, described seal ring 9 is embedded in the circular draw-in groove 12 of described protecting cover 8 lower surfaces, is provided with after seal ring 9, makes catch bar 10 pass described actuator housing 1 place and possesses and have stronger sealability.
The present invention has disclosed a kind of sensitive-type turbocharger bypass driver, the mode that the present invention adopts the mode that adopts fan 4 and spring 5 to combine in the inner chamber of actuator housing 1 to carry out pilot pressure only relies on the elastic performance of spring to carry out the mode of pilot pressure in replacing prior art, simple and reliable for structure, only need set up again a fan 4, cost is lower, and the mode that can rotate by fan 4 can improve control accuracy, increase the sensitivity of turbosupercharger, specific works principle of the present invention is: as shown in Figure 2, ambient pressure enters the pressure chamber 6 of actuator housing 1 by suction tude 11, the fan 4 that drive is positioned at pressure chamber 6 rotates, now fan 4 rotations produce further air pressure, because the pressure chamber 6 of actuator housing 1 seals, cause the air pressure bounce-back that fan 4 produces to be pushed diaphragm 2, in conjunction with ambient pressure, diaphragm 2 is pushed together simultaneously, thereby diaphragm 2 is pressed down, and drive the piston 3 that is positioned at piston cavity 7 to press down, finally make catch bar 10 move down and open external device, as shown in Figure 3, in the time that 11 mouthfuls of suction tude pass into without air pressure, compressed spring 5 resiliences of piston 3, drive on catch bar 10 and move, close external device, now the piston 3 in piston cavity 7 pushes diaphragm 2, now in pressure chamber 6, pressure increases, make fan 4 start reversion, thereby the pressure in pressure chamber 6 is discharged sooner, the present invention is simple and reliable for structure, can effectively improve the sensitivity of turbosupercharger.
