空気供給装置
Document Type and Number:
Japanese Patent JP7163149
Kind Code:
B2
Abstract:
To provide an air supply device capable of suppressing degradation of performance of a combustor by unifying a distribution of flow rate in a circumferential direction of a discharge flow channel.SOLUTION: An air supply device 1 includes impellers 5A, 5B sending air A in a centrifugal direction D1, a diffuser flow channel 15 disposed at an outer part in the centrifugal direction D1, of the impeller 5B, a guide flow channel 16 disposed at an outer part of the diffuser flow channel 15 and communicated with the diffuser flow channel 15, and a discharge flow channel 17 formed between an inner body portion 7b and an outer body portion 7a, and communicated with the guide flow channel 16. The discharge flow channel 17 includes a rear-side area 17b at a normal rotation side in a rotating direction R of the impellers 5A, 5B, and a front-side area 17a at a reverse rotation side in the rotating direction R in a cross-section S1 view orthogonal to a center line L1 of the outer body portion 7a. At least a part of the discharge flow channel 17 is provided with a flow channel restriction area Ra in which a flow channel area of the front-side area 17a is narrower than a flow channel area of the rear-side area 17b.SELECTED DRAWING: Figure 4
