Detailed description of the invention
Below in conjunction with the accompanying drawings presently preferred embodiments of the present invention is described in detail, so that advantages and features of the invention can be easier to be readily appreciated by one skilled in the art, thus protection scope of the present invention is made apparent clear and definite defining.
Referring to Fig. 1, the embodiment of the present invention includes:
A kind of sensitive-type turbocharger bypass driver, including: actuator housing 1, diaphragm 2, piston 3, fan 4 and catch bar 10, it is internal that described diaphragm 2 is arranged on described actuator housing 1, and the inner chamber of actuator housing 1 is divided into pressure chamber 6 and plunger shaft 7, described piston 3 is arranged in described plunger shaft 7, and it is close to below described diaphragm 2, described piston 3 is internal is 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 that described piston 3 is fixing with described fan 4 to be connected, the other end passes described actuator housing 1 and is connected to external device, above described actuator housing 1, side is fixed with air inlet pipe 11, described air inlet pipe 11 connects with described pressure chamber 6.
Described air inlet pipe 11 and described actuator housing 1 are fixing by the way of stamping riveting to be connected, and can improve riveting intensity, thus improve service life by the way of stamping riveting.
Described actuator housing 1 is provided with protective jacket 8 between the bottom surface of plunger shaft 7 and the spring 5 within described piston 3.
The lower surface indent of described protective jacket 8, and constitute circular draw-in groove 12 with the bottom surface of described plunger shaft 7, after being provided with protective jacket 8, it is possible to efficiently reduce spring 5 and the damage of actuator housing 1, improve service life further.
Described actuator housing 1 is provided with sealing ring 9 with the junction of described catch bar 10.
