Abstract
A diaphragmatic elbow damper joining two angularly oriented channels and configured to seal the channels in the absence of fluid flow overcoming gravity and atmospheric pressure.
Claims19
A flow control device comprising:
- a first channel;
- a second channel;
- and
- a diaphragm positioned between the first channel and the second channel, wherein the diaphragm includes a first side and a second side that faces an opposite direction as the first side,
- wherein the diaphragm is configured and arranged to alternatively operate in both:
- a closed condition in which flow from the first channel to the second channel is impeded, and an open condition in which flow from the first channel to the second channel occurs,
- wherein the diaphragm is configured and arranged to change from the closed condition to the open condition when a force of a positive fluid flow through the first channel towards the first side of the diaphragm exceeds a combination of a gravitational force and a force of atmospheric pressure upon the second side of the diaphragm, and
- further wherein:
- said diaphragm includes a concave contour, when considered from the second side, when said diaphragm is in the closed condition;
- and
- said diaphragm includes a convex contour, when considered from the second side, when said diaphragm is in the open condition.

A flow control device comprising:
- a first channel;
- a second channel;
- and
- a diaphragm positioned between the first channel and the second channel, wherein the diaphragm includes a first side and a second side that faces an opposite direction as the first side,
- wherein the diaphragm is configured and arranged to alternatively operate in both:
- a closed condition in which flow from the first channel to the second channel is impeded, and an open condition in which flow from the first channel to the second channel occurs,
- wherein the diaphragm is configured and arranged to change from the closed condition to the open condition when a force of a positive fluid flow through the first channel towards the first side of the diaphragm exceeds a combination of a gravitational force and a force of atmospheric pressure upon the second side of the diaphragm, and
- wherein:
- said first channel extends in a first axial direction;
- said second channel also extends in said first axial direction;
- and
- an outermost peripheral edge of the diaphragm defines a single plane, when the outermost peripheral edge is considered in its entirety, and the single plane of the outermost peripheral edge of the diaphragm is parallel with respect to the first axial direction.
