  "abstract": "Valve for a system for applying a covering product, including projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, these projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool. The projecting or hollow shapes of the valve include a first peripheral profile having at least one planar surface, and a second peripheral profile located behind the first profile relative to an outer end of the valve. The second profile has at least one first planar surface aligned with the planar surface of the first profile, and at least one second planar surface angularly offset relative to the planar surface of the first profile, such that the second planar surface of the second profile forms a shoulder relative to the first profile.",
  "claims": [
    "1. A valve for a system for application of a covering product, comprising projecting or recessed shapes on a peripheral part, configured to cooperate with projecting or recessed shapes of a dedicated mounting and dismounting tool, said projecting or recessed shapes of the valve being configured to transmit a rotational movement to the valve, and to be secured to the tool, wherein the projecting or recessed shapes of the valve comprise: a first peripheral profile having at least one planar surface; and a second peripheral profile located behind said first peripheral profile relative to an outer end of the valve, and wherein the second peripheral profile has at least one first planar surface aligned with the planar surface of said first peripheral profile, and at least one second planar surface that is angularly offset relative to the planar surface of said first peripheral profile, such that the second planar surface of the second peripheral profile forms a shoulder relative to said first peripheral profile.",
    "2. The valve according to claim 1, wherein said first peripheral profile comprises three planar surfaces, and wherein said second peripheral profile comprises: three planar surfaces that are aligned with said three planar surfaces of said first peripheral profile; and three planar surfaces that are angularly offset relative to said three planar surfaces of said first peripheral profile.",
    "3. An application system of a covering product comprising a valve according to claim 1.",
    "4. A dedicated tool for mounting and dismounting a valve according to claim 1, comprising projecting or recessed shapes provided on an inner peripheral surface of a bore of the tool, configured to cooperate with the projecting or recessed shapes provided on the peripheral part of the valve, the projecting or recessed shapes of the tool being configured to transmit a rotational movement to the valve, and to be secured to the valve, the projecting or recessed shapes of the tool comprising: one or several planar peripheral surfaces; and a radial withdrawn groove of said one or several planar peripheral surfaces of the tool, the groove being configured to receive part of the valve by securing the valve with the tool, wherein the groove comprises a resilient peripheral element exerting a resilient axial force against the part of the valve received in the groove."

  "description_excerpt": "The present invention relates to a valve and a system for application of a covering product comprising such a valve. The invention also relates to a dedicated mounting and dismounting tool for such a valve.\n\nSystems for application of covering products, such as paint sprayers, include at least one valve controlling a needle maneuverable to allow circulation of paint. The valve is generally controlled by injecting pressurized control air into a chamber. The pressurized air acts on a piston controlling the needle. Such a valve includes sealing devices preventing the paint from entering the valve toward the chamber on the one hand, and preventing the pressurized control air from escaping from the chamber and other fluids from entering the chamber on the other hand.\n\nSuch valves, as well as other types of valves, must be mounted or dismounted under access conditions that are sometimes complicated. Sometimes, several types of tools, or a tool that must be turned over, must be used, which involves increased manipulation times if, for example, a tool falls during the manipulations, or if one of the necessary tools is not available. During such manipulations, there is also a risk of dropping the valve during mounting or dismounting.\n\nThe invention aims to address these drawbacks by proposing a new valve for a system for the application of a covering product, which has shapes making it possible to facilitate its mounting and dismounting with a single tool, while reducing the fall risks.",
