Abstract: A tint measuring device configured for being connected in series in a fluid flow circuit, the tint measuring device including at least one light source configured for emitting polychromatic light towards the fluid in a measurement zone; a light sensor configured for receiving a light signal either reflected from or transmitted through the fluid, the reflected or the transmitted light signal corresponding to the optical reflection or the optical transmission, respectively, by the fluid, of the polychromatic light emitted towards the fluid by the at least one light source; and a computing unit configured for performing a spectral analysis of the light signal received by the light sensor and for determining a chromatic signature of the fluid.

Abstract: A modular block for an electric pump for a fluid product, including a main body defining a housing extending along a main axis, the main body having a general shape having a discrete rotational symmetry relative to a reversion axis, the main axis of the housing within the housing extending on a first side of a central plane outside the central plane, the reversion axis being included in the central plane, and a pumping device extending at least partially in the housing of the main body.

Abstract: The pumping installation (16) comprises a pneumatic pump (22) for pumping a fluid (12) and a system (24) for supplying the pneumatic pump (22) with compressed gas. The supply system (24) comprises a source (34) of compressed gas and a fluidic connection (36) that fluidly connects the source (34) to the pneumatic pump (22). The pumping installation (16) also comprises a system (38) for controlling the supply of the compressed gas to the pneumatic pump (22), wherein the control system (38) comprises a valve (40) mounted on the fluidic connection (36) and switchable between a blocking state, in which the valve (40) prevents the flow of compressed gas between the source (34) and the pneumatic pump (22), and a passing state, in which the valve (40) allows the circulation of compressed gas between the source (34) and the pneumatic pump (22).

Abstract: A pump for a liquid product including a body inwardly delimiting a compression chamber, in which a piston is mounted sliding, as well as an external motor coupled to the piston for movement thereof by a piston rod passing through a wall secured to the pump body, through a passage opening equipped with a sealing device including a stack of seals kept gripped axially against the pump body, the sealing device including an axial compression member inserted between a crown, included in the sealing device, and the wall secured to the pump body.

Abstract: A sealing device for a system for applying a liquid coating product comprises an inner conduit suitable for sealably surrounding an actuating rod of the application system, a frame and a sealing gasket made from a synthetic material comprising an O-ring mounted around a lip of the gasket suitable for being pressed against the actuating rod, the frame and the gasket forming a single-piece assembly suitable for being mounted in a housing of the application system.

Abstract: The present invention concerns an air motor comprising a piston and a housing, the piston being received in the housing and dividing the housing into two primary chambers of variable volume. Said motor comprises a first direct supply valve for supplying a first primary chamber of the two primary chambers and a second direct supply valve for supplying the other primary chamber, said two valves each being movable relative to at least one respective seat. The first valve and the second valve are mounted on a same stem movable relative to the housing in a direction parallel to the direction of movement of the piston, and the stem is configured to be moved between a first position and a second position by moving means activated by the piston.
