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.
Claims14
An inline aspirator for an inflatable assembly, comprising:
- a first portion including a first end, the first end defining a primary gas inlet;
- a second portion downstream of the first portion and including a second end, the 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;
- an external surface opposite the internal surface;
- an orifice located between the first end and the second end, wherein the orifice extends from the internal surface to the external surface, and wherein the orifice is configured to entrain ambient air with a primary gas flowing from the primary gas inlet to the primary gas outlet;
- a spring coupled between the first portion and the second portion;
- and
- a stopper attached to the first portion, wherein the stopper is located within a volume defined by the second portion, and wherein the stopper is configured to restrict translation of the second portion away from the first portion after a predetermined distance.
