Protrusion 67 is formed as the periphery wall 65 by annular space towards internal perisporium 64.

Protrusion 68 is formed as connecting the internal perisporium 64 and periphery wall 65 of annular space.

The first purpose for forming protrusion 66 etc. is to form flow path in cooling space B, which makes cooling Jie Matter is flowed in cooling space B by piston flow, to prevent short circuit and improve hot transmitting.

Here, by protrusion 66,67,68 circumferentially around the flow path of cooling space B formation one week.When from When nozzle 75 supplies cooling medium to cooling space B, can flow protrusion 66 by being alternately arranged and protrusion 67 it Between and from nozzle 76 be discharged.

As described above, when formed flow path and improve heat transmitting the case where when, it is preferable that protrusion 66 etc. all with fixation Side cover members 63 are in close contact, the short circuit moved to prevent fluid stopping.

That is, as shown in Z-Z arrow direction, it is preferable that the height h of protrusion 66 etc. is set as maximum value.

Another purpose that protrusion 66 etc. is set be make its these with fin effect to improve hot transmitting.When simple When ground forms the case where flow path is purpose, protrusion 66 etc. is arranged and also obtains identical effect in fixed side cover members 63 Fruit.

But it in order to obtain fin effect, needs the equal setting of protrusion 66 in affixed side holding member 61 so that fixed The area that side holding member 61 is contacted with cooling medium becomes larger.Moreover, in the case where further preferred fin effect, Ke Yiwu Protrusion 66 need to be waited and be in close contact with fixed side cover members 63 and be set as flowing at random.

Another purpose for forming protrusion 66 etc. is to provide the inner bolt being arranged for fixing affixed side vane member 62 Position.

Since cooling space B is arranged to cool down affixed side vane member 62, it is advantageous to be configured to and affixed side Vane member 62 is overlapped.Therefore, when affixed side vane member 62 being mounted on affixed side holding member 61 by bolt, preferably exist Bolt is also configured in the space of cooling space B.

In this case, it is needed on a side at least among the affixed side holding member 61 or affixed side vane member 62 Through bolt hole.But cooling medium when since through hole being arranged on the affixed side holding member 61 for be formed with cooling space B It is leaked from cooling space B to 62 side of affixed side vane member, therefore preferably not such setting.

Therefore, through hole is set on affixed side vane member 62, and thickeies the thickness of the plate of affixed side holding member 61 Degree, makes to form the inner bolt not penetrated.

It is preferred, however, the movement of the heat in transmitting affixed side holding member 61, and the plate thickness t shown in Z-Z arrow It is thin.It is preferable therefore that the height h for forming thin plate thickness t, and improving protrusion 66 etc..

That is, (being seen from Z-Z arrow (from Y-Y arrow) and shown in Z-Z arrow as shown in Y-Y arrow Examine), protrusion 66 at this time etc., which has, is capable of forming the screw hole 96 not penetrated and required width w and thickness (height h+ plate Thickness t).

In this way, passing through the screw hole 96, Neng Gouke for forming bolt on the protrusion 66 of affixed side holding member 61 is equal By ground affixed side vane member 62 is installed on affixed side holding member 61, and is reliably prevented from cooling medium and leaks to 62 side of affixed side vane member, the cooling medium flow the cooling space B in affixed side holding member 61.

Can mode identical with cooling space B consider cooling space A, still, by 50 institute of high speed rotation rotating vane It is important that being set as not generating eccentrically loaded structure in rotary side holding member 51, it is preferable that the inflow entrance of cooling medium And outflux is set as multiple and equivalent arrangements.

More than, it is based on attached drawing, embodiments of the present invention are described in detail, still, are specifically constructed unlimited In present embodiment, the design alteration for not departing from present subject matter is also contained in the present invention.

For example, having been illustrated with rotating vane 50 shown in Fig. 1 etc. and fixed blade 60 all in its center partially with recessed The case where falling into blade surface, still, the blade surface of a side can be formed as flat table as documented by patent document 3 Face, or the central part of the blade surface of a side as documented by patent document 4 can form protrusion.
