First Claim
Patent Images
1. A valve component for controlling fluid flow, the valve component comprising:
- a body having a first surface and a second surface;
at least one tortuous flow channel extending between the first surface and the second surface, the flow channel configured to have a plurality of sections and a plurality of direction changes within the extent between the first surface and the second surface, each section of the flow channel at least partially defined by a floor portion and a ceiling portion;
the body being formed as one-piece by additive manufacturing to concurrently define the flow channel as a void space; and
wherein, for each section of the flow channel, each of the floor portion and ceiling portion being disposed at an acute angle relative to a plane containing a layer of material forming the body such that each section of the flow channel has a general chevron cross-sectional shape.

Abstract
A valve component for controlling fluid flow comprises a body having a first surface and a second surface. At least one tortuous flow channel extends between the first surface and the second surface. The flow channel is at least partially defined by a floor portion and a ceiling portion. The body is formed as one-piece by additive manufacturing to concurrently define the flow channel as a void space. At least one of the floor portion and ceiling portion is disposed at an acute angle relative to a plane containing a layer of material forming the body.

10. A trim cage for controlling fluid flow, the trim cage comprising:
-
a unitary body having a substantially tubular configuration with a longitudinal central axis, the body having an inner surface and an outer surface; at least one tortuous flow channel extending through the body from the inner surface to the outer surface for fluid flow therethrough, the tortuous flow channel configured to have a plurality of sections and a plurality of direction changes within the extent between the inner surface and the outer surface, each section of the flow channel is offset relative to an adjacent section, each section of the flow channel has an axial floor portion and axial ceiling portion; and wherein each of the axial floor portion and axial ceiling portion are disposed at an acute angle relative to a plane extending normal to the longitudinal central axis of the body such that each section of the flow channel has a general chevron cross-sectional shape. - View Dependent Claims (11, 12, 13, 14, 15)
