Abstract: A pulse valve arrangement includes a valve housing on which is fixed a control valve The valve housing includes a circular cylindrical portion with a valve member movably arranged therein. The valve chamber has an inlet adapted to be connected to a pressure medium source for allowing pressure medium to flow into the valve chamber and an outlet through which pressure medium flows out of the valve chamber. The control valve may be closed in which the outlet of the valve chamber is moved to a closing position blocking the flow of pressure medium, or may be opened in which the outlet of the valve chamber is moved to an opening position allowing a pulse of pressure medium therethrough. The valve member within the valve housing is freely displaceable within the circular cylindrical portion of the valve housing based on the pressure within the valve chamber as controlled by the control valve.

Abstract: A stator component of a turbomachine is composed substantially of at least one axially extending outer ring (10) which serves as a frame of an inner ring composed of partial segments (20). The partial segments are arranged on one another such that, on the rotor side, they form a coherent circular circumferential surface in relation to the rotational movement of rotor blades (30). The individual partial segment (20) is composed of a material of uniform construction or, at least in a radial direction, of multiple partial bodies constructed from different materials, such as for example ceramic, wherein a partial segment thus formed exhibits predetermined stress and/or expansion behaviour as a function of the load ranges of the turbomachine.

Abstract: The invention relates to a can-combustor for a can-annular combustor arrangement in a gas turbine. The can combustor includes an essentially cylindrical casing with an axially upstream front panel and an axially downstream outlet end. The can combustor further includes a number of premixed burners, extending in an upstream direction from said front panel and having a burner exit, supported by this front panel, for supplying a fuel/air mixture into a combustion zone inside the casing. Up to four premixed burners are attached to the front panel in a substantially annular array. Each burner has a conical swirl generator and a mixing tube to induce a swirl flow of said fuel/air mixture.
