Abstract
A monolithic pressure regulator may comprise a boding comprising a base wall, an end wall, and a side wall, a cavity within the body, an input port in fluid communication with the cavity, an output port in fluid communication with the cavity, a first vesicle configured to regulate a flow of fluid through the input port into the cavity at a source pressure to exit through the output port at a regulated pressure, wherein the first vesicle comprises a first vesicle wall contiguous with a bulkhead and at least one of the base wall or the end wall.
Claims8
A monolithic pressure regulator, comprising:
- a body comprising a base wall, an end wall, and a side wall;
- a cavity within the body;
- an input port in fluid communication with the cavity;
- an output port in fluid communication with the cavity;
- and
- a first vesicle configured to regulate a flow of fluid through the input port into the cavity at a source pressure to exit through the output port at a regulated pressure, wherein the first vesicle comprises a first vesicle wall contiguous with a bulkhead and at least one of the base wall or the end wall;
- and
- a second vesicle, wherein the first vesicle, the second vesicle, and the bulkhead are disposed within the cavity,
- wherein bulkhead fluidly isolates the first vesicle and the second vesicle,
- wherein the second vesicle is in fluid communication with a sense port through the base wall.
An evacuation system for use with an aircraft, comprising:
- an inflatable evacuation device configured to be inflated by a compressed fluid source;
- and
- a monolithic pressure regulator coupled to the compressed fluid source and the inflatable evacuation device, the monolithic pressure regulator comprising:
- a body comprising a base wall, an end wall, and a side wall;
- a cavity within the body;
- an input port in fluid communication with the cavity and the compressed fluid source;
- an output port in fluid communication with the cavity and the inflatable evacuation device;
- a first vesicle configured to regulate a flow of fluid through the input port into the cavity at a source pressure to exit through the output port at a regulated pressure,
- wherein the first vesicle comprises a first vesicle wall contiguous with a bulkhead and at least one of the base wall or the end wall;
- and
- a second vesicle, wherein the first vesicle, the second vesicle, and the bulkhead are disposed within the cavity,
- wherein bulkhead fluidly isolates the first vesicle and the second vesicle,
- wherein the second vesicle is in fluid communication with a sense port through the base wall.
An article of manufacture, including:
- a body comprising a base wall, an end wall, and a side wall;
- a cavity within the body;
- an input port in fluid communication with the cavity;
- an output port in fluid communication with the cavity;
- a first vesicle configured to regulate a flow of fluid through the input port into the cavity at a source pressure to exit through the output port at a regulated pressure,
- wherein the first vesicle comprises a first vesicle wall contiguous with a bulkhead and at least one of the base wall or the end wall;
- and
- a second vesicle, wherein the first vesicle, the second vesicle, and the bulkhead are disposed within the cavity,
- wherein bulkhead fluidly isolates the first vesicle and the second vesicle,
- wherein the second vesicle is in fluid communication with a sense port through the base wall.
