摘要： A blade array for turbomachines comprises blades disposed between an inner wall and an outer wall. The inner wall and/or the outer wall is provided with a suction port near at least some blades. This port has a first end situated along the upper surface in a region of the blade extending from the point of maximum curvature to the neck of the passage between said blade and the adjacent blade. The port enabling the efficiency to be increased is oriented along an isobar line. Its length is such that the second end is spaced from the upper surface of the blade by a distance between one quarter and one half the width of the neck of the inter-blade passage.

摘要： The present invention relates to a valve including a valve member co-operating with a seat provided with a crenellated portion disposed around the portion of the seat on which the valve member rests, said crenellated portion being constituted by teeth separated by gaps, the inside walls of the teeth being portions of a vertical axis cylinder, the width l of the gaps being less than the width b of the inside walls of the teeth, wherein the end wall of the valve member facing the crenellated portion when the valve member is in its closed position is convex in shape, co-operating with the inside wall of each tooth to form a channel that flares from top to bottom of the tooth, the point of contact C between the valve member and the seat being at a distance d from the base B of the crenellated portion lying in the range 0.25 times to 0.5 times the width l of the gap. Vibrations are eliminated at partial load and pressure fluctuations downstream from the valve are reduced.
摘要翻译：本发明涉及一种阀，其包括与座椅配合的阀门构件，所述座椅设置有围绕所述阀构件所在的所述座椅部分周围设置的锯齿状部分，所述锯齿形部分由被间隙分开的齿构成，所述内壁所述齿是垂直轴圆柱体的一部分，所述间隙的宽度l小于所述齿的内壁的宽度b，其中当所述阀构件处于其中时所述阀构件的所述端壁面向所述锯齿状部分闭合位置是凸形的，与每个齿的内壁协作以形成从牙齿的顶部到底部的弹道的通道，阀构件和座椅之间的接触点C距离锯齿状部分的基底B位于间隙宽度l的0.25倍至0.5倍的范围内。在部分负载下消除振动，减小阀门下游的压力波动。

摘要： A turbine stage comprising a set of fixed vanes (1) fixed to the stator (3) of the turbine and supporting a diaphragm, followed by a set of moving vanes (8) mounted on a disk (9) which is fixed to the rotor (6) of the turbine, the periphery of the set of moving vanes (8) having seals (10) constituted by a plurality of chambers (11). The disk (9) includes suction orifices (16) opening out into the space between the diaphragm (4) and the disk (9) and disposed in the vicinty of the peripheral portion of the disk (9). The suction orifices (15) are connected by ducts (17) passing through at least some of the moving vanes (8) to outlet orifices (18) which open out in the tips of the vanes (8) downstream from the seals (10) within a chamber (11) thereof. The disturbed flow at the roots of the fixed vanes (2) and the leakage flow between the diaphragm (4) and the rotor (6) are sucked into the orifices (16), thereby improving efficiency.
