A device for supplying at least one sprayer with a liquid coating product comprises a plurality of valves for controlling the flow of the coating product to the sprayer, these valves being aligned along a principal axis of the supply device. Each valve comprises a moving needle, a valve body, pneumatic driver for moving the needle in translation, the driver comprising a piston constrained to move in translation with the needle and slidably mounted in a guide body. The principal axis and the separation/approach axis of a valve coincide at a unique point and together define a principal plane of the valve. The separation/approach axis of each valve is contained within a cone centered on an axis perpendicular to the principal axis and belonging to the principal plane of the valve, the apex of the cone being coincident with the unique point.

Device for supplying a sprayer with a liquid coating product

A device for supplying a sprayer with a liquid coating comprises a one valve having a moving needle, a valve body defining a circulation volume for the coating and a seat for supporting the needle. A pneumatic drive for translating the needle along an axis away from or towards the seat comprises a piston constrained to move with the needle and sliding within a guide body. A head and the guide body define a variable volume chamber. The head is constrained to rotate with the volume via slots on the head and corresponding protruding elements on the guide body. The guide body is screwed onto the valve body along the axis. The head includes driving reliefs for rotation of the head around the axis for screwing onto the valve body. A tool for mounting/dismounting the device comprises a maneuvering handle and an end-piece having reliefs complementary to the driving reliefs.

Device for supplying a sprayer with a liquid coating product and tool for mounting/dismounting such a device

A device for supplying at least one sprayer with a liquid coating product comprises at least one valve for controlling the flow of the coating product to the sprayer. The valve comprises a moveable needle, a valve body which defines a circulation volume of the coating product and a seat for supporting the needle in the closed configuration of the valve. A pneumatic driver drives the pointer in translation along an axis away from or towards the seat. The pneumatic driver comprises a piston constrained to move in translation with the needle and mounted slidably in a guide body. The pneumatic driver also comprises an end-piece penetrating into a transfer chamber. The communication line links the end-piece or the transfer chamber with a variable-volume chamber defined by the guide body and a first face of the piston.

This valve () comprises: a body (); a first channel () for channelling the flow of a fluid; a second channel () for channelling the flow of a fluid; a first valving element () which is movable translationally in a first direction (X), between an open position and closed position of the or each first channel (), the body () forming a first seat () for the first valving element (); and a second valving element () which is movable translationally in a second direction (X), between an open position and a closed position of the or each second channel (); the first direction (X) and the second direction (X) being parallel or coinciding with each other. The first valving element () defines a housing () for the second valving element (). The first valving element () forms a second seat () for the second valving element ().

Valve for spraying coating material, and an atomizer including such a valve

The invention relates to an electronic board that comprises: a planar projection plate () provided between an intake opening () and a discharge opening (); and a plurality of rectilinear nozzles (-) extending through said plate along a projection direction, the projection direction of each nozzle defining an angle relative to a direction perpendicular to a sole () of the electronic component () to be cooled, the angle &#x3b1; being comprised in a range of &#x2212;30 and +30&#xb0;.
