## 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.

## Claims

### Claim 1

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.

### Claim 2 (depends on 1)

The monolithic pressure regulator of claim 1, wherein the first vesicle comprises one of a sinusoidal vesicle wall, a triangular vesicle wall, a trapezoidal vesicle wall, a sine-dwell vesicle wall, a rectangular vesicle wall, or an elliptical vesicle wall.

### Claim 3 (depends on 1)

The monolithic pressure regulator of claim 1, wherein the bulkhead comprises a leg extending from a perimeter of the bulkhead, wherein a distal end of the leg comprises a foot having a sealing face oriented toward the input port.

### Claim 4

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.

### Claim 5 (depends on 4)

The evacuation system of claim 4, wherein the first vesicle comprises one of a sinusoidal vesicle wall, a triangular vesicle wall, a trapezoidal vesicle wall, a sine-dwell vesicle wall, a rectangular vesicle wall, or an elliptical vesicle wall.

### Claim 6 (depends on 4)

The evacuation system of claim 4, wherein the bulkhead comprises a leg extending from the perimeter of the bulkhead,
wherein a distal end of the leg comprises a foot having a sealing face oriented toward the input port.

### Claim 7

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.

### Claim 8 (depends on 7)

The article of manufacture of claim 7, wherein the bulkhead comprises a leg extending from the perimeter of the bulkhead,
wherein a distal end of the leg comprises a foot having a sealing face oriented toward the input port.
