    Abstract: A method can include additively manufacturing a first portion of a part in a first build direction on a first build plate, removing the first portion of the part from the first build plate and inserting the first portion of the part on a second build plate that is configured to receive at least a portion of the first portion of the part. The method can also include additively manufacturing, in a second build direction relative to the first build direction, a second portion on the first portion of the part that is on the second build plate. In certain embodiments, the method can include removing the part from the second build plate.

    Abstract: A dynamic seal assembly is disclosed for use in a valve having an upstream pressure side and a downstream pressure side, the dynamic seal assembly including an annular seal member having a generally C-shaped cross-section and including opposed upstream and downstream legs defining an internal cavity with an opening facing toward the upstream pressure side of the valve, wherein the upstream leg has a radial length that is greater than a radial length of the downstream leg and includes a retaining foot that extends angularly away from the upstream leg in an upstream direction at an angle of between about 0° and 90°, and a metallic spring is disposed within the internal cavity of the seal member for providing a constant sealing force to the seal member.

    Abstract: A valve assembly for a fuel injector that includes a sleeve member having an interior chamber, a piston member supported for movement within the interior chamber of the sleeve member and separating an upstream pressure side of the valve assembly from a downstream pressure side of the valve assembly, and a dynamic sealing device mounted to one of the sleeve member and the piston member for sealingly isolating the upstream pressure side of the valve assembly from the downstream pressure side of the valve assembly. The dynamic sealing assembly includes a PTFE seal member having a generally C-shaped cross-section defining an internal cavity having an opening about the outer periphery thereof the seal member, and a helical spring disposed within the internal cavity of the seal member for providing a constant sealing force to the seal member. The dynamic sealing device is positioned in the valve assembly so that the opening of the internal cavity of the seal member faces away from the upstream pressure side of the valve assembly and towards the downstream pressure side of the valve assembly.

    Abstract: A valve for regulating fluid flowing bidirectionally therethrough includes a first flow body defining a passage configured to direct fluid flow in a downstream direction defined from the inlet to the outlet. The inlet includes an enlargement configured to provide decreased resistance to fluid flow in the downstream direction relative to flow in an upstream direction opposite the downstream direction.
