Abstract
An adjustable actuator for a waste gate exhaust valve of a turbocharger includes a housing having a first opening therein for communication with the pressure outlet of the turbocharger and a second opening therein remote from the first opening. The actuator also includes a rod interconnecting the housing and the waste gate exhaust valve through the second opening. The actuator further includes a pivotal mounting bracket connected to the housing adjacent the second opening. One or more flange portions extend radially outward from a central body portion which has an aperture therein for receiving the rod. The actuator also includes a fastener for selectively clamping the bracket to the housing such that the bracket can rotate and tilt with respect to housing when the fastener is loosened and is held in a fixed positioned once the fastener is tightened. The actuator utilizes a flat elastic diaphragm at a seam between two portions of the house to divide it into first and second chambers respectively and provide increased durability. One of the spring guides for mounting the rod assembly to the housing can be threaded into the housing so as to provide axial adjustment, which translates into a change to the preload on the spring and thereby the boost pressure setting of the turbocharger.
