摘要：
In a centrifugal machine for a refrigeration or air conditioning system and including a casing, an impeller, a variable width diffuser assembly leading from the impeller, and a plurality of vanes received through respective complementary-shaped openings in a movable wall member, there is provided a sealing means in the openings between the vanes and movable wall member for preventing leakage of fluid through the openings, thereby increasing the operating efficiency of the machine.
