A compressor having a variable-geometry ported shroud includes a compressor housing defining an inlet duct, a shroud, and a bypass passage. A variable-geometry port extends through the shroud into the bypass passage, and includes an adjustable mechanism that is selectively configurable to adjust the meridional location of the port between at least first and second meridional locations. In one embodiment an opening extends through the shroud, and the adjustable mechanism includes a bypass control device that is disposed within the opening and is axially movable therein. The bypass control device has an axial length less than that of the opening such that there is always a portion of the opening that remains unblocked by the bypass control device and forms a port through the shroud. The bypass control device is axially movable between at least first and second positions to place the port at the first and second meridional locations.

What is claimed is: 1. A compressor having a variable-geometry ported shroud, comprising:a compressor housing defining an inlet duct, a shroud, and a bypass passage;a compressor wheel rotatably mounted in the compressor housing; anda variable-geometry port comprising an opening extending through the shroud into the bypass passage, the variable-geometry port comprising an adjustable mechanism that is selectively configurable to adjust a meridional location of the port between at least first and second meridional locations, wherein the mechanism comprises a bypass control device disposed within the opening and axially movable therein, the bypass control device having an axial length less than that of the opening such that in all possible axial positions of the bypass control device there is a portion of the opening that remains unblocked by the bypass control device and forms the port through the shroud, the bypass control device being axially movable within the opening between at least first and second positions that respectively place the port at the first and second meridional locations.
