Abstract: A valve including a body having an inner central orifice and a chamber, a piston formed by a rod and by a head mounted in the chamber, the rod extending outside the body and moving in a bore of an application system. The valve includes a first sealing device around the rod on one side of the valve where the rod extends outside the body, part of the chamber being filled with a pressurized control fluid to obtain movement of the piston against the force of a spring housed in the body. The valve includes a second sealing device around the rod, between the first sealing device and the chamber. The valve includes a vent duct in the rod that communicates with the inner central orifice between the first and second sealing devices and emerges in the open air or in part of the chamber communicating with the open air.

Abstract: A piston-diaphragm assembly for a valve with a piston comprising a stem and a needle. The stem comprises a piston groove with a groove proximal rim. The needle is attached to a stem distal end. The assembly comprises a diaphragm with a peripheral annular ring, an internal annular ring received in the piston groove for attaching the diaphragm thereto, and an annular membrane connecting the annular rings. The needle comprises a crown, which surrounds the stem and externally covers the internal annular ring and which comprises a crown rim, which ends the crown at the groove proximal rim. The diaphragm is radially interposed between the groove proximal rim and the crown rim, being in contact with the crown rim.

Abstract: The present invention relates to a valve comprising a body having a central conduit accommodating a sliding piston and a diaphragm connecting the body to the piston surrounding the piston. The diaphragm comprises an annular membrane for separating the central conduit from a pressurized fluid chamber. The body comprises an annular cradle, which extends radially between the central conduit and a peripheral annular ring of the diaphragm. The diaphragm takes an initial shape, where the annular membrane is distant from the annular cradle, when the piston is in a distal position and no overpressure occurs. The diaphragm is elastically deformed into stretched shapes, where the annular membrane comes in contact and mates with the annular cradle, under the effect of an overpressure occurring in the pressurized fluid chamber.

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.

Abstract: The present invention relates to a rotary atomizer for coating products comprising a main body and a bowl rotated by a rotating member about a axis of rotation defined by the main body. The bowl is equipped with first means of magnetic coupling apt to cooperate with matching second means of magnetic coupling fastened to a non-rotating part of the atomizer. The first and second means of coupling are apt to exert a force at least partially axial with respect to the axis of rotation of the bowl, the force inducing the coupling in rotation of the bowl with the rotating member. The second means of magnetic coupling are supported by an air supply skirt directly mounted on the main body.

Abstract: A rotary coating sprayer including a spray bowl rotating about an axis of rotation and an air turbine for driving the bowl. The turbine includes a rotor and a body forming a support for the rotor and defining at least one air feedline for a rotation chamber wherein the rotor blades are arranged. The feedline includes an intermediate chamber defined, radially to the rotation axis, between the body and a ring mounted around the body. In this way, lowering of temperature of an element of the sprayer housing due to flow of exhaust air from the turbine, is limited.
