## Abstract

An inflatable article repair and inflation kit comprises a canister of sealing fluid; an inlet connectable to a pressure source and connected to the canister; a selector valve interposed fluidically between the inlet and the canister; a conduit connected to the selector valve, in parallel with the canister; and a flow resistance of die selector valve and the canister to reduce the pressure in the canister with respect to the pressure in the conduit. The inflatable article repair and inflation kit ensures the best pressure into the sealing fluid canister.

## Claims

### Claim 1

An inflatable article repair and inflation kit comprising a canister (3) of sealing fluid; an inlet (4) connectable to a pressure source and connected to said canister (3); a selector valve (12) interposed fluidically between said inlet (4) and said canister (3); a conduit (13) connected to said selector valve (12), in parallel with said canister (3); and a flow resistance (23) located between a movable shutter (23) of said selector valve (12) and said canister (3) to reduce the pressure in said canister (3) with respect to the pressure in said conduit (13).

### Claim 2 (depends on 1)

A kit as claimed in claim 1, characterized in that said flow resistance (23) is fitted to a hollow body (24) housing said movable shutter (25).

### Claim 3 (depends on 2)

A kit as claimed in claim 2, characterized in that said flow resistance (23) forms one piece with said hollow body (24).

### Claim 4 (depends on 1)

A kit as claimed in claim 1, characterized by comprising an acoustic indicator (23) which emits an acoustic signal when the compressed airflow pressure and/or flow rate exceed a given threshold.

### Claim 5 (depends on 4)

A kit as claimed in claim 4, characterized in that said acoustic indicator is powered by compressed airflow generated by said pressure source.

### Claim 6 (depends on 5)

A kit as claimed in claim 5, characterized in that said acoustic indicator is defined by said flow resistance (23).

### Claim 7 (depends on 1)

A kit as claimed in claim 1, characterized in that said selector valve (12) comprises a first and second fluid seal (29, 30) arranged in series with respect to a further inlet (21) defined by said selector valve (12).

### Claim 8 (depends on 7)

A kit as claimed in claim 7, characterized in that said selector valve (12) comprises a cap (26) for closing said movable shutter (25) inside said hollow body (24); and in that said first and second fluid seal (29, 30) are interposed between said further inlet (21) and said cap (26).

### Claim 9 (depends on 1)

A kit as claimed in claim 1, characterized by comprising a casing (2) housing at least said selector valve (12); and in that said canister (3) is connected, and fixed with respect, to said casing (2).
