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.

Rotary coating product sprayer and method for controlling a surface temperature of such a sprayer

A turbine for a fluid-spraying device including a turbine body, and a rotor rotating a bowl relative to the body about an axis, the rotor being surrounded by the turbine body in a plane perpendicular to the common axis, the turbine body guiding the rotation of the rotor, the rotor being rotated by a stream of gas, the turbine body receiving the stream of gas at the outlet of the rotor, and delimiting at least one outlet duct configured to guide a first portion of the received stream into a space delimited in a plane perpendicular to the common axis by the bowl and a skirt.

Turbine, fluid-spraying device, associated facility and manufacturing method

A sprayer support including a housing for a high-voltage unit or plug, a guiding member for at least one coating product hose, a retention member for air hoses, a first fastening member for fastening to a robot, and a second fastening member for fastening to a sprayer. The housing, the guiding member, the retention member, the first fastening member, and the second fastening member are formed from a single part.

A turbine for a fluid-ejecting device, including a body and a rotor rotating a bowl about an axis, the turbine also including a tube mounted coaxially with the body and intended to be mounted coaxially with a skirt, a first portion of the tube being surrounded by the turbine body and a second portion being surrounded by the skirt and offset in the downstream direction relative to the first portion, the tube being rotatable about the axis relative to the body, the body preventing the translational movement of the tube parallel to the axis, and the outer face of the aforementioned second portion having a first thread engaging with a second thread formed on the skirt in order to press the skirt against the turbine body.

Turbine for a fluid-ejecting device, fluid-ejecting device, and assembly comprising such a device and tool

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.

Valve and system for application of a covering product including such a valve

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.
