Embodiment Construction

[0030] Combine below Figure 1~Figure 6 This program will be further described with specific examples.

[0031] Such as Figure 1~Figure 6 As shown, this embodiment relates to a turbocharger bypass valve actuator, which includes a push rod chamber 1, an actuator push rod 2 that passes through the push rod chamber 1, and is located in the push rod chamber 1 and sleeved on the actuator. The spring 3 on one end of the push rod 2; the upper part of the push rod chamber 1 is provided with at least 2 sealed cavities, and each of the sealed cavities is connected through a connecting channel in turn, and an air inlet nozzle is provided on one of the sealed cavities 18.

[0032] Further, when the number of the sealed cavities is equal to 2, the number of the connecting channels is equal to 1, which is used as the first connecting channel 8; the two sealed cavities are respectively the first sealed cavity 5 and the second sealed cavity 16, the first sealed cavity 5 and the second sea...

Abstract

The invention discloses a bypass valve actuator for a turbocharger and belongs to the field of turbocharger operating mechanisms. The bypass valve actuator comprises a push rod cavity, an actuator push rod penetrating the push rod cavity and a spring located in the push rod cavity and connected to one end of the push rod cavity of the actuator in a sleeving manner. At least two sealing cavities are formed in the upper portion of the push rod cavity. Every two sealing cavities sequentially communicate with each other through a connecting channel. An air inlet nozzle is arranged on one of the sealing cavities. According to the bypass valve actuator for the turbocharger, at least two sealing cavities are formed in the upper portion of the push rod cavity, all the sealing cavities sequentiallycommunicate with one another through the connecting channels, the pressure from the air inlet nozzle is more stable through the multiple connected sealing cavities, following pressure value detectionis facilitated, the air pressure of the air inlet nozzle is from an outlet of a compressor of the turbocharger, the sealing cavities next to the push rod cavity not only have the pressure stabilizingand air pressure transmitting functions, but also can control the actions of an actuator pull rod.

Description

technical field [0001] The invention relates to a turbocharger bypass valve actuator, which belongs to the field of turbocharger operating mechanisms. Background technique [0002] The existing air intake pressure sensor is installed at the position of the air intake manifold, where the pressure fluctuation is relatively large, especially when the engine operating conditions change, such as rapid acceleration or sudden braking, the pressure fluctuation in the intake pipe will affect the signal collection. The voltage value has a great influence. [0003] The performance index of the engine set by the vehicle manufacturer is a comprehensive consideration of power, economy and environmental protection, and does not bring out the potential of the vehicle. However, for the safety of the vehicle, the power system has set a safe range for the value of each sensor. Therefore, in order to adapt to the safety range, the vehicle often has the problem of being unable to exert its max...
