The compressor comprises a housing defining an inlet passage and a diffuser passage, and an impeller blade rotatably mounted in the housing between the inlet and diffuser thereof. The compressor further comprises an annular recess defined by the housing and in communication with the diffuser passage, and an annular diffuser valve supported by the housing for axial movement within the annular recess and the diffuser passage between minimum and maximum throttling positions. A stop member is located adjacent to the housing and includes an end section axially located forward of the annular recess to limit forward axial movement of the diffuser valve. A fastening member is radially located external of the annular recess and disengagably secures the stop member to the housing.
