## Abstract

A support unit for a structure within a pressure vessel that includes an external load distribution plate, an internal load distribution plate, a standoff unit between the external load distribution plate and the internal load distribution plate that extends through an opening in a pressure vessel.

## Claims

### Claim 1

A support unit for a structure within a pressure vessel that includes:
an external load distribution plate;
an internal load distribution plate;
a standoff unit between the external load distribution plate and the internal load distribution plate that extends through an opening in a pressure vessel.

### Claim 2 (depends on 1)

The support unit of claim 1, wherein the standoff unit is a tube.

### Claim 3 (depends on 1)

The support unit of claim 1, wherein the standoff unit includes a biasing unit on the standoff unit that acts to press a washer on to the external load distribution plate to create a pressure tight seal.

### Claim 4 (depends on 1)

The support unit of claim 1, wherein the external and internal plates are made from steel.

### Claim 5 (depends on 1)

The support unit of claim 1, wherein the external and internal plates are made from aluminum.

### Claim 6 (depends on 1)

The support unit of claim 1, wherein the external and internal plates are made from different materials having the same coefficient of thermal expansion as the truss beams.

### Claim 7 (depends on 3)

The support unit of claim 3, wherein the biasing member is a spring.

### Claim 8 (depends on 3)

The support unit of claim 3, wherein the washer includes a sealing unit that creates a pressure tight seal between the washer and the standoff unit.

### Claim 9 (depends on 8)

The support unit of claim 8, wherein the sealing unit is an O-ring.

### Claim 10 (depends on 1)

The support unit of claim 1, wherein the external and internal plates are connected to the standoff unit by fasteners.

### Claim 11 (depends on 1)

The support unit of claim 1, wherein the opening in the pressure vessel is sized to accommodate expansion and contraction of the pressure vessel.
