The improved variable geometry diffuser (VGD) mechanism for use with a centrifugal compressor is disclosed. The VGD mechanism extends substantially fully into the diffuser gap, VGD mechanism will be more fully to control the different working functions. VGD mechanism diffuser gap is to minimize, by preventing the reverse flow of the refrigerant gas through the diffuser gap during compressor stop process since substantially blocked, rotary compressor station during compressor stop process and the associated temporary load by the full extension of the diffuser ring It will be used. During start-up, may be the load and the impeller speed increases, the gas flow through the diffuser gap to remove a temporary surge and stall to be able to be effectively As the delay, and, thus are problems caused by the starting load is alleviated by a low speed under. VGD mechanism may be used for capacity control in order to achieve a more effective turn-down under low speed.
