Classification: CPC F  Y | IPC F

Claim 0:
1. An engine component for a turbine engine which generates a hot gas flow, and provides a cooling fluid flow, comprising:
a wall separating the hot gas flow from the cooling fluid flow and having a heated surface along which the hot gas flows and a cooled surface facing the cooling fluid flow; and
at least one cooling hole comprising:
a connecting passage having a centerline and extending between an inlet at the cooled surface and an outlet at the heated surface, with the inlet defining a first inlet dimension and with the outlet defining a first outlet dimension greater than the first inlet dimension,
a diffusing section terminating in the outlet and having an increasing cross-sectional area in a direction toward the heated surface, and
a recessed portion extending from the inlet toward the diffusing section and defining the first inlet dimension;

wherein the inlet defines a second inlet dimension and the outlet defines a second outlet dimension less than the second inlet dimension;
wherein the outlet defines a first bound area and the inlet defines a second bound area and, when viewed along the centerline of the connecting passage, at least a portion of the second bound area lies within the first bound area;
wherein the first bound area defines a first geometric center point and the second bound area defines a second geometric center point; and
wherein the first and second geometric center points are linearly unaligned with the centerline of the connecting passage and are offset from each other in a first direction and a second direction when viewed along the centerline of the connecting passage, and the first direction and the second direction are perpendicular to the centerline of the connecting passage.
