Abstract

The present disclosure relates generally to a manifold including a plurality of manifold channels disposed therethrough, each manifold channel including a manifold channel opening, and a seal plate, including a plurality of seal plate apertures disposed thereon, operably coupled to the manifold, wherein the seal plate includes at least one seal plate channel extending between at least two of the plurality of seal plate apertures.

First claim

What is claimed is:

1. A manifold assembly comprising:
a first manifold including a plurality of exterior surfaces including a manifold top surface;
a first manifold channel and a second manifold channel, each extending between the manifold top surface and another of the plurality of exterior manifold surfaces;
the first manifold channel and the second manifold channel having a respective first channel opening and second channel opening in the manifold top surface;
a seal plate having a seal plate top surface and a seal plate bottom surface spaced from the seal plate top surface in a first direction, the first direction being an axial direction that defines a seal plate thickness;
the seal plate bottom surface disposed against the manifold top surface;
a first seal plate aperture and a second seal plate aperture extending through the seal plate in the axial direction;
the first seal plate aperture and the second seal plate aperture respectively aligned with the first channel opening and the second channel opening;
a seal plate channel extending in a second direction connecting the first seal plate aperture and the second seal plate aperture, wherein the second direction is perpendicular to the first direction;
the seal plate channel defining a fluid circuit between the first manifold channel and the second manifold channel; and
the seal plate channel narrowing in a third direction, whereby the seal plate channel is configured to control a flow characteristic of the fluid circuit, and wherein the third direction is perpendicular to the first direction and the second direction.

2. The seal plate of claim 1 , wherein the flow characteristic configured to be controlled by the seal plate channel is one or more of flow pressure drop, flow temperature and mass flow rate.

3. The assembly of claim 1 , comprising:
a first conduit and a second conduit comprising respective first and second conduit ends; and
the first and second conduit ends respectively connecting to the top surface of the seal plate and being aligned with the first seal plate aperture and the second seal plate aperture.

4. The assembly of claim 3 , wherein:
the first conduit and second conduit comprise respective third and fourth conduit ends that are configured for connecting to a second manifold.

5. A gas turbine engine comprising the assembly of claim 4 .

6. The assembly of claim 1 , wherein the seal plate channel comprises a venturi type channel.

7. The assembly of claim 1 , wherein:
the seal plate channel defines a restriction in the third direction;
the restriction is located in the middle, in the second direction, of the seal plate channel; and
the restriction widens in the third direction proximate the first seal plate aperture and the second seal plate aperture.

8. The assembly of claim 1 , wherein the seal plate channel defines a geometric step-wise restriction in the third direction.
