The turbo actuator is used to open and close the turbocharger vanes, therefore controlling the amount of exhaust gases that reach the turbine wheel and regulating the turbo boost output.
Turbo vacuum actuators are a mechanism that supplies a switching or actuation force to the turbo vanes through a nipple on the actuator. The more vacuum that is applied to the actuator the more the turbo vanes will open or close.
The vacuum actuators consists of small, sealed chamber which is equipped with a close-fitting piston or captive diaphragm. An actuator arm ( mechanical link ) is then connected to the turbo vane control pin.
There are also a few other types of actuators, we also stock the electronic actuator for the turbochargers compatible.
