## Abstract

There is provided a breathing assembly for an aircraft that includes a breathing mask to be connected to a source of breathing gas. The assembly also includes a stowage box forming a receptacle for receiving the breathing mask in a stowage position, and a valve assembly comprising a valve having an open position in which the valve allows the feed of breathing gas to the breathing mask and a closed position in which the valve prevents the feed of breathing gas to the breathing mask, the valve assembly being supported by the breathing mask. There may also be provided a retaining element connected to the stowage box and cooperating with the valve assembly to maintain the valve in the closed position when the breathing mask is in the stowage position.

## Claims

### Claim 1

A breathing assembly for aircraft comprising:
a breathing mask to be connected to a source of breathing gas,
a stowage box forming a receptacle for receiving the breathing mask in a stowage position, said stowage box having an opening for extracting the breathing mask from the stowage box, and
a valve assembly comprising a valve having an open position in which the valve allows the feed of breathing gas to the breathing mask and a closed position in which the valve prevents the feed of breathing gas to the breathing mask, the valve being automatically positioned in the open position when the breathing mask is extracted from the stowage box,
wherein the valve assembly is supported by the breathing mask and the breathing assembly further comprises a retaining element which is connected to the stowage box and cooperates with the valve assembly to maintain the valve in the closed position when the breathing mask is in the stowage position, wherein
the valve assembly comprises a casing in which the valve slides along a sliding direction between the open position and the closed position,
the casing has at least one slot, and
in the stowage position, the retaining element is inserted in the slot and the valve abuts an abutment surface of the retaining element extending perpendicularly to the sliding direction.

### Claim 2 (depends on 1)

Breathing assembly according to claim 1 wherein the retaining element has an end portion having a fork form.

### Claim 3 (depends on 2)

Breathing assembly according to claim 2 wherein:
the casing has a first slot and a second slot opposed to the first slot,
the end portion of the retaining element comprises a first branch and a second branch,
in the stowage position, the first branch of the retaining element is inserted in the first slot, the second branch of the retaining element is inserted in the second slot and the valve abuts both first and second branches of the retaining element.

### Claim 4 (depends on 2)

Breathing assembly according to claim 2 wherein:
the casing comprises an inner passage,
the valve comprises:
a stem portion comprising an inner duct which is sealingly connected to the inner passage of the casing and an external shoulder abutting the abutment surface of the retaining element when the breathing mask is in the stowage position, and
a head portion mounted on the stem portion, the head portion closing the inner passage of the casing when the valve is in the closing position.

### Claim 5 (depends on 4)

Breathing assembly according to claim 4 wherein the head portion is elastically mounted on the stem portion.

### Claim 6 (depends on 5)

Breathing assembly according to claim 5 wherein the valve assembly further comprises a spring connecting the head portion and the stem portion of the valve.
