## Abstract

An ozone converter includes an outer housing having an inlet and an outlet and a core disposed within the outer housing, the core including a central passageway formed therein and passing thorough the core. The converter also includes an ozone control assembly that allows air to pass through the central passageway in an closed mode and prevents flow thorough the central passageway in an open mode, the assembly including cover flaps that cover a portion of the core in the closed mode and that do not cover the core in the open mode.

## Claims

### Claim 1

An ozone converter comprising:
an outer housing having an inlet and an outlet;
a core disposed within the outer housing, the core including a central passageway formed therein and passing through the core;
an ozone control assembly that allows air to pass through the central passageway in a closed mode and prevents flow thorough the central passageway in an open mode, the ozone control assembly including cover flaps that cover a portion of the core in the closed mode and that do not cover the core in the open mode; and
an actuator that causes the cover flaps to move when the ozone converter is changed from the closed mode to the open mode or from the open mode to the closed mode;
wherein the ozone control assembly includes:
a rod that is controlled by the actuator; and
a central passageway access cover connected to the rod;
wherein the cover flaps are connected to the rod.

### Claim 2 (depends on 1)

The ozone converter of claim 1, wherein the ozone converter is in an aircraft and is in the closed mode when the aircraft is on the ground.

### Claim 3 (depends on 1)

The ozone converter of claim 1, wherein the cover flaps are arranged perpendicular to the central passageway access cover.

### Claim 4 (depends on 1)

The ozone converter of claim 1, wherein the central passageway access cover prevents flow through the central passageway in the open mode and allows flow through the central passageway in the closed mode.

### Claim 5 (depends on 1)

The ozone converter of claim 1, wherein the actuator causes the rod to rotate to change the ozone converter from the closed mode to the open mode or from the open mode to the closed mode.
