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 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 at least one 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.

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.

11. 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 including at least two sections, 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. - View Dependent Claims (12, 13, 14, 15, 16)

17. A method of manufacturing a unitary trim cage, the method comprising the steps of:
-
providing at least one layer of material to define a body base with an inner opening surface and an outer surface; adding successive layers of material to the body base along a lay down direction and in such a manner to maintain the inner opening surface and define at least one tortuous flow channel extending between the inner opening surface and the outer surface, the tortuous flow channel including a plurality of sections; wherein each section of the flow channel is offset relative to an adjacent section and the surfaces defining the flow channel are accomplished without internal support, and at least a portion of each section extends at an acute angle relative to direction of additive lay down; and adding at least one layer of material to define a body cap in such a manner to maintain the inner opening surface and the outer surface. - View Dependent Claims (18, 19, 20)
