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.
Claims12
A flow control device, comprising a first channel, a second channel, and a diaphragm section;
- the diaphragm section at least partially encasing a diaphragm and comprising a first end, a second end, and at least one wall section;
- the diaphragm having a first side and a second side, the first side facing or exposed to the at least one wall section;
- the at least one wall section being continuous with the first channel and the second channel;
- the at least one wall section, the first end, and the second end forming a throughspace, the throughspace providing for fluid communication between the first channel, the diaphragm section, and the second channel;
- the first channel having a first central axis and a first cross section, the second channel having a second central axis and a second cross section, the first central axis being orthogonal to the first cross section, the second central axis being orthogonal to the second cross section, and the first central axis being substantially perpendicular to the second central axis;
- the diaphragm being disposed between the first end and the second end, configured to fill the throughspace when in a closed position and vacate the throughspace when in an open position, and comprising a central portion and a perimetral portion, the perimetral portion being fixed to the diaphragm section;
- and
- said perimetral portion of the diaphragm includes an outermost peripheral edge that 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 sloped with respect to both the first central axis and the second central axis.

A flow control device comprising:
- a first channel, said first channel extends in a first axial direction;
- a second channel, said second channel extends in a second axial direction that is perpendicular to the first axial direction;
- and
- a diaphragm positioned between the first channel and the second channel, wherein the diaphragm includes a first side that faces towards the first channel and a second side that faces an opposite direction as the first side, 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 sloped with respect to both the first axial direction and the second axial direction,
- 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, and
- 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.
