Abstract
Official abstract text for this publication.
A valve assembly for an inflation system that includes a pressure relief valve and a vent valve. The pressure relief valve has a pressure relief housing and a pressure relief valve poppet. The pressure relief housing defines a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway and a second pressure relief cavity disposed between the first wall and a second wall. The pressure relief valve poppet is movably disposed within the first pressure relief cavity and the second pressure relief cavity. The vent valve has a vent housing and a vent valve poppet. The vent housing defines a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall. The vent valve poppet is movably disposed within the vent cavity.
First claim
Opening claim text (preview).
What is claimed is: 1. A valve assembly for an inflation system, comprising: a pressure relief valve that extends along a transverse axis, having: a pressure relief housing defining: a first pressure relief cavity that is disposed between a first end wall defining a first flow port and a first wall defining a passageway, wherein the first end wall and the first wall both extend parallel to a longitudinal axis and are spaced apart from each other along the transverse axis; and a second pressure relief cavity disposed between the first wall and a second wall, wherein the second wall extends parallel to the longitudinal axis, and the first wall and the second wall are spaced apart from each other along the transverse axis, so that the first wall is transversely between the first end wall and the second wall, and a pressure relief valve poppet movably disposed within the first pressure relief cavity and the second pressure relief cavity, wherein the pressure relief valve poppet is configured to move along the transverse axis, and a first vent port that is fluidly connected to the first pressure relief cavity, the first vent port defined in a transversely extending first perimeter wall of the first pressure relief cavity; and a first charge port that is fluidly connected to the second pressure relief cavity, the first charge port defined in a transversely extending second perimeter wall of the second pressure relief cavity, and a vent valve that extends along the transverse axis, having: a vent housing defining a vent cavity that is disposed between the second wall defining a vent flow port and a second end wall, wherein the second end wall extends parallel to the longitudinal axis, and the second wall and the second end wall are spaced apart from each other along the transverse axis, so that the second wall is transversely between the first wall and the second end wall, and a vent valve poppet movably disposed within the vent cavity, wherein the vent valve poppet is configured to move along the transverse axis. 2. The assembly of claim 1 , wherein the pressure relief housing defines a second charge port that is fluidly connected to the vent cavity, the second charge port defined in a transversely extending vent perimeter wall of the vent cavity. 3. The assembly of claim 2 , wherein the vent housing defines a second vent port arranged to vent at least portion of a first fluid flow after completion of inflation of an inflatable structure, the second vent port defined in the transversely extending vent perimeter wall, so that the second vent port is transversely between the second wall and the second charge port.
