Abstract

A valve for pressurized fluid, with or without incorporated pressure-reducing valve, comprising a body accommodating a fluid circuit having an upstream end designed to be placed in communication with a reserve of pressurized fluid and a downstream end designed to be placed in communication with a using device, the circuit comprising an isolation valve element in order to selectively close off the circuit, the valve element being controlled by a lever mounted so as to pivot on the body between a rest position in which the isolation valve element is held in a position of closing the circuit and an active position in which the lever moves the isolation valve element into a position of opening the circuit , wherein the lever comprises at least one opening, wherein the valve comprises a functional abutment mounted on the body and wherein only in the rest position the opening accommodates within it a portion of the functional abutment mounted on the body.

First claim

What is claimed is:

1. A valve for pressurized fluid, with or without incorporated pressure-reducing valve, comprising a body comprising a fluid circuit having an upstream end designed to be placed in communication with a reserve of pressurized fluid and a downstream end designed to be placed in communication with a pressurized fluid using device, the circuit comprising an isolation valve element configured to selectively close off the circuit, the isolation valve element being configured to be controlled by a lever, wherein the lever is mounted so as to be capable of pivoting on the body between a rest position in which the isolation valve element is configured to close the fluid circuit and an active position in which the isolation valve element is configured to open the fluid circuit, wherein the lever comprises at least one opening, wherein the valve comprises a functional abutment mounted on the body and wherein only in the rest position the opening accommodates within the opening a portion of the functional abutment mounted on the body, wherein the upstream end of the fluid circuit, the downstream end of the fluid circuit, and the functional abutment are different, wherein the opening matches the shape of the functional abutment and wherein there is no mechanical collision between the opening and the functional abutment as the lever pivots between the rest position and the active position.

2. The valve of claim 1 , wherein the functional abutment is adapted to limit the movement of the lever.

3. The valve of claim 1 , wherein the functional abutment is adapted to limit deformation of the lever in the event of an impact.

4. The valve of claim 1 , wherein one end of the lever is articulated on the body and wherein at least one bearing portion of the lever is situated close to the axis of articulation of the lever.

5. The valve of claim 1 , wherein at least one bearing portion of the lever is situated close to a second end of the lever that is opposite to where one end of the lever is articulated on the body.

6. A tank of pressurized fluid comprising the valve of claim 1 .
