Abstract
An inline for an inflatable assembly may comprise a first end defining a primary gas inlet and a second end defining a primary gas outlet. An internal surface may define a flow path extending from the primary gas inlet to the primary gas outlet. An orifice may be located between the first end and the second end. The orifice may be defined, at least partially, by a radial wall extending from the internal surface to the external surface. The orifice may be configured to entrain ambient air with a primary gas flowing from the primary gas inlet to the primary gas outlet.
Claims18
An inline aspirator for an inflatable assembly, comprising:
- a first end defining a primary gas inlet;
- a second end defining a primary gas outlet;
- an internal surface defining a flow path extending from the primary gas inlet to the primary gas outlet, wherein the internal surface is oriented toward a central axis extending from the primary gas inlet to the primary gas outlet;
- an external surface opposite the internal surface, wherein the external surface is oriented away from the central axis;
- and
- an orifice located between the first end and the second end and extending from the internal surface to the external surface, wherein the orifice is defined, at least partially, by a radial wall extending from the internal surface to the external surface, and wherein the radial wall is sloped such that a radially outward portion of the radial wall is located closer to the primary gas inlet as compared to a radially inward portion of the radial wall, and wherein an inlet of the orifice is defined by the external surface and an outlet of the orifice is defined by the internal surface.

A life raft assembly, comprising:
- an inflatable raft;
- a conduit fluidly coupled to the inflatable raft;
- a charge cylinder fluidly coupled to the conduit;
- and
- an inline aspirator located between a first portion of the conduit and a second portion of the conduit, the inline aspirator including:
- a first end fluidly coupled to the first portion of the conduit and defining a primary gas inlet;
- a second end fluidly coupled to the second portion of the conduit and defining a primary gas outlet;
- an internal surface defining a flow path extending from the primary gas inlet to the primary gas outlet, wherein the internal surface is oriented toward a central axis extending from the primary gas inlet to the primary gas outlet;
- an external surface opposite the internal surface, wherein the external surface is oriented away from the central axis;
- and
- an orifice located between the first end and the second end and extending from the internal surface to the external surface, wherein the orifice is defined, at least partially, by a radial wall extending from the internal surface to the external surface, and wherein the radial wall is sloped such that a radially outward portion of the radial wall is located closer to the primary gas inlet as compared to a radially inward portion of the radial wall, and wherein an inlet of the orifice is defined by the external surface and an outlet of the orifice is defined by the internal surface.

An inflatable assembly, comprising:
- an inflatable structure;
- a charge cylinder fluidly coupled to the inflatable structure;
- and
- an inline aspirator fluidly coupled between the inflatable structure and the charge cylinder, the inline aspirator including:
- a first end fluidly defining a primary gas inlet;
- a second end defining a primary gas outlet;
- an internal surface defining a flow path extending from the primary gas inlet to the primary gas outlet, wherein the internal surface is oriented toward a central axis extending from the primary gas inlet to the primary gas outlet;
- an external surface opposite the internal surface, wherein the external surface is oriented away from the central axis;
- and
- an orifice located between the first end and the second end and extending from the internal surface to the external surface, wherein the orifice is defined, at least partially, by a radial wall extending from the internal surface to the external surface, and wherein the radial wall is sloped such that a radially outward portion of the radial wall is located closer to the primary gas inlet as compared to a radially inward portion of the radial wall, and wherein an inlet of the orifice is defined by the external surface and an outlet of the orifice is defined by the internal surface.
