1. A seal for a gas turbine engine comprising:
- a first component having a face and a second component having a face abutting the face of the first component, the first and second components separating a region of high pressure from a region of low pressure, the faces of the first and second components each including a discontinuity configured such that when the faces are placed in a confronting relationship, the discontinuities form a cavity, anda seal member positioned in the cavity, the seal member cooperating with the cavity such that high pressure gas in the region of high pressure that traverses the interface between the confronted faces urges the seal member against a portion of the discontinuities to seal the interface between the seal member and those portions of the faces engaged by the seal member,wherein the discontinuity in the face of the first component and the discontinuity in the face of the second component form an angle with an apex of the angle positioned nearer the region of low pressure as compared the region of high pressure, the seal member positioned such that the high pressure that traverses the interface between the confronted faces urges the seal member into contact with the faces defining the angle to control the flow of gas from the region of high pressure to the region of low pressure.

Abstract
A gas turbine engine assembly includes a seal formed by the interface between first and second support components. The support components are each formed to include a notch. Adjacent notches cooperate to form a space when assembled. A seal member is located in the space.

10. A seal for a gas turbine engine comprising:
- a first component having a face and a second component having a face mirroring the face of the first component, the first and second components separating a region of high pressure from a region of low pressure, the faces placed in a confronting relationship, such that the faces define a space, and
a seal member positioned in the space such that high pressure gas in the region of high pressure urges the seal member against an interface between the faces, wherein the space has a tapered shape such that the high pressure gas urges the seal member into the taper to seal the region of high pressure from the region of pressure. - View Dependent Claims (11, 12, 13, 14)
