Abstract
Methods and systems are provided for a slidable sleeve valve actuation system for a turbocharger compressor. In one example, an actuator assembly for a slidable sleeve of a turbocharger compressor may comprise: a fork arm coupled to the slidable sleeve; a rotatable lever arm coupled to the fork arm via a rigid connecting shaft; a connector rod coupled between the lever arm and a rotatable element; and an actuator unit coupled to the rotatable element and attached to an attachment case, the attachment case coupled to the turbocharger compressor. The actuator assembly may be actuated to move the slidable sleeve from one position along a casing treatment to another position along the casing treatment, thereby adjusting the alignment of sleeve slots on the slidable sleeve relative to choke or surge slots on the casing treatment.
