EXHAUST-GAS TURBOCHARGER

摘要

An exhaust-gas turbocharger with a compressor with a charge pressure control device. An actuator is provided which moves a control rod arrangement. The control rod arrangement is in turn rotatably connected to a lever. The charge pressure control device is actuated by the lever. A pin is arranged on the lever. The control rod arrangement has a bushing which is pushed onto the pin. The connection between pin and bushing constitutes a rotatable connection for enabling the lever to be actuated by the control rod arrangement. This arrangement is very simple to produce and very simple to assemble because the bushing must merely be pushed onto the pin.
