Embodiment Construction

[0025] To facilitate navigation from one drawing to another, the Figures 2 to 8 The orthogonal coordinate system X-Y-Z is shown in .

[0026] figure 1 A device 1 for spraying a liquid product is shown, comprising a tank 2 of the liquid product, a pump 4 and a sprayer 6 . In practice, the device 1 may comprise several other nebulizers, but these are not shown for the sake of clarity of the drawing. Optionally, the device 1 also includes a pressure regulator 8 . Tank 2, pump 4, sprayer 6 and flow restrictor 8 (if applicable) are connected by a tubing assembly 5 adapted to transport liquid product between the various parts of the apparatus.

[0027] Liquid products are, for example, coating products such as paints or varnishes.

[0028] The nebulizer 6 may be of the pneumatic or "airless" type, and may or may not be electrostatic. it can be as figure 1 The manual spray gun shown can also be an automatic spray gun known per se.

[0029] The device 1 also comprises a filter...

Abstract

The invention relates to a filter for a liquid or viscous product and a spraying facility comprising such a filter. The filter for the liquid for viscous product includes a filtering element (14) anda bucket (12) defining a receiving volume (V12) accommodating the filtering element (14), the filter (10) including a liquid or viscous product intake tubing and a liquid or viscous product dischargetubing (18), the filter (10) including a valve (20) configured to assume a first position, where the valve (20) couples the intake tubing to the receiving volume (V12) and this receiving volume (V12)to the discharge tubing (18), and a second position, where the valve (20) couples the intake tubing to the discharge tubing (18) and isolates the receiving volume (v12) relative to the two tubes.

Description

technical field [0001] The invention relates to a filter for liquid or viscous products. The filter comprises a filter element and a barrel defining a containment volume for the filter element, as well as inlet and discharge pipes for liquid or viscous products. Background technique [0002] In the field of equipment comprising distribution circuits with filters for liquid or viscous products, bypass circuits can be placed to ensure the continuity of service of the equipment during the replacement of filter elements. Several methods of modifying filter elements are known. Each method has advantages and disadvantages. The main disadvantages are especially the high price (e.g. in the case of bypass circuits with two filter bodies and four valves), or the risk of contamination, e.g. in the case of bypass circuits with simple piping and no filter bodies In some cases, liquid or viscous products may deteriorate between uses. [0003] It is known from US-A-2012031821 to produc...
