Abstract

This apparatus comprises a filter cartridge 11 arranged on a filter head 1 and a liquid separator. The receptacle 5 of the separator is attached to the head 1 and is provided with a purge valve 7 the plug 8 of which is loaded by a closing spring 9. To simplify the construction of the apparatus and to reduce the number of components needed to keep the filter cartridge 11 in place, the closing spring 9, via its end extending away from the plug 8 of the purge valve 7, is applied directly or via an intermediary part such as a supporting plate 10 to the filter cartridge 11, thus holding this cartridge in place on the filter head 1. The plug 8, the spring 9 and the plate 10 are made of a single piece of plastic.

Description

L'invention concerne un appareil de filtrage et d'élimination de liquide pour maintenir un fluide de pression pneumatique en bon état d'utilisation, comprenant une cartouche filtrante disposée sur une tête de filtre et un séparateur de liquide, dont le récipient est fixé à la tête de filtre et est pourvu d'une soupape de purge de liquide avec un clapet chargé par un ressort de fermeture. The invention relates to a liquid filtering and elimination apparatus for maintaining a pneumatic pressure fluid in good working condition, comprising a filter cartridge disposed on a filter head and a liquid separator, the container of which is fixed to the filter head and is provided with a liquid purge valve with a valve loaded by a closing spring.

Sur un appareil connu de ce type, la tête de filtre présente des orifices latéraux de raccordement pour l'amenée et l'évacuation du fluide de pression et, sur son côté inférieur, une surface d'appui pour le récipient, lequel est vissé étanche sur la tête de filtre. On a known device of this type, the filter head has lateral connection orifices for supplying and evacuating the pressure fluid and, on its lower side, a bearing surface for the container, which is screwed tightly on the filter head.

Le récipient contient un dispositif de tourbillonnement qui confère une rotation au fluide de pression arrivant, une cartouche filtrante et une plaque de maintien, lesquelles sont serrées ensemble sur la tête de filtre par une vis de tension disposée sur l'axe du récipient.The container contains a swirling device which rotates the incoming pressure fluid, a filter cartridge and a holding plate, which are tightened together on the filter head by a tensioning screw arranged on the axis of the container.

La soupape de purge se trouve au fond du récipient et son clapet, traversant un orifice de purge, est pressé de façon étanche contre le bord de cet orifice par un ressort de fermeture. On connatt également des exécutions où la cartouche filtrante est vissée au moyen d'un filetage sur la tête de filtre, avec serrage simultané du dispositif de tourbillonnement. Les exécutions connues comprennent un certain nombre de pièces séparées dont la fabrication est coûteuse et qui demandent en outre un montage laborieux à l'assemblage de l'appareil et lors de son entretien.The purge valve is located at the bottom of the container and its valve, passing through a purge orifice, is pressed in leaktight manner against the edge of this orifice by a closing spring. We also know versions where the filter cartridge is screwed by means of a thread on the filter head, with simultaneous tightening of the swirl device. Known embodiments include a number of separate parts which are expensive to manufacture and which also require laborious assembly during assembly of the device and during its maintenance.

L'invention vise à simplifier les appareils connus du type indiqué au début, surtout en diminuant le nombre de pièces nécessaires. The invention aims to simplify the known devices of the type indicated at the start, especially by reducing the number of parts required.

L'appareil selon l'invention est caractérisé en ce que le ressort de fermeture, par son extrémité éloignée du clapet de la soupape de purge, est appuyé directement ou par une pièce intermédiaire, par exemple une plaque de maintien, sur la cartouche filtrante et maintient cette cartouche en place sur la tête de filtre. Cette exécution supprime le besoin d'un dispositif particulier pour la fixation de la cartouche filtrante à la tête de filtre. Cette fonction est maintenant assurée en même temps par le ressort de fermeture de la soupape de purge, ce qui supprime plusieurs pièces nécessaires à la fixation de la cartouche filtrante avec les exécutions connues. The apparatus according to the invention is characterized in that the closing spring, by its end remote from the valve of the purge valve, is supported directly or by an intermediate piece, for example a holding plate, on the filter cartridge and keeps this cartridge in place on the filter head. This execution eliminates the need for a particular device for fixing the filter cartridge to the filter head. This function is now performed at the same time by the closing spring of the purge valve, which eliminates several parts necessary for fixing the filter cartridge with known designs.

De ce fait, l'appareil selon l'invention se compose seulement d'un faible nombre de pièces, de sorte qu'il peut être assemblé simplement et rapidement, notamment aussi au moyen de machines automatiques, et que son entretien est également simple.Therefore, the device according to the invention consists only of a small number of parts, so that it can be assembled simply and quickly, especially also by means of automatic machines, and that its maintenance is also simple.

Selon un mode de réalisation préféré de l'invention, le ressort de fermeture, le clapet, la soupape de purge et éventuellement aussi la plaque de maintien, ou un élément d'appui de la cartouche filtrante, constituent une unité cohérente, de préférence sous forme d'une pièce d'un seul tenant en matière plastique. Dans ce mode de réalisation, une seule pièce peu coûteuse en plastique assure toutes les fonctions qui devaient être remplies par plusieurs pièces compliquées dans les exécutions connues. According to a preferred embodiment of the invention, the closing spring, the valve, the purge valve and possibly also the retaining plate, or a support element of the filter cartridge, constitute a coherent unit, preferably under shaped as a single piece of plastic. In this embodiment, a single inexpensive plastic part provides all the functions which had to be fulfilled by several complicated parts in known embodiments.

D'autres caractéristiques et avantages de l'invention ressortiront plus clairement de la description qui va suivre d'un exemple de réalisation nonlimitatif, ainsi que de la figure unique du dessin annexé, qui est une coupe axiale d'un appareil selon l'invention. Other characteristics and advantages of the invention will emerge more clearly from the description which follows of a nonlimiting exemplary embodiment, as well as from the single figure of the appended drawing, which is an axial section of an apparatus according to the invention. .

L'appareil représenté possède une tête de filtre 1 avec des orifices de raccordement 2 et 3 pour l'amenée et l'évacuation du fluide de pression pneumatique qu'il s'agit de maintenir en bon état d'utilisation. -La tête de filtre 1 présente en bas un prolongement cylindrique 4 qui est fileté intérieurement et dans lequel est vissé un récipient 5 pour le liquide séparé du fluide pneumatique. The device shown has a filter head 1 with connection orifices 2 and 3 for supplying and evacuating the pneumatic pressure fluid which it is necessary to maintain in good working condition. -The filter head 1 has at the bottom a cylindrical extension 4 which is internally threaded and into which is screwed a container 5 for the liquid separated from the pneumatic fluid.

Le récipient 5 est serré sur la tête de filtre 1 avec interposition d'une bague d'étanchéité 6. Le récipient 5 contient dans son fond une soupape 7 pour purger le liquide. Cette soupape comporte un clapet 8 qui traverse un orifice du récipient 5, un ressort de fermeture 9 qui se raccorde à ce clapet et une plaque de maintien 10 à l'extrémité supérieure du ressort. Par l'intermédiaire de la plaque de maintien 10, le ressort de fermeture 9 presse une cartouche filtrante 11, avec interposition d'une jupe de tourbillonnement 12, contre une surface d'appui annulaire 13 qui entoure l'entrée d'un espace de sortie 14 communiquant avec l'orifice 3 de la tête 1.The container 5 is clamped on the filter head 1 with the interposition of a sealing ring 6. The container 5 contains a valve 7 at its bottom for purging the liquid. This valve comprises a valve 8 which passes through an orifice in the container 5, a closing spring 9 which is connected to this valve and a retaining plate 10 at the upper end of the spring. By means of the retaining plate 10, the closing spring 9 presses a filter cartridge 11, with the interposition of a swirling skirt 12, against an annular bearing surface 13 which surrounds the entry of a space for outlet 14 communicating with the orifice 3 of the head 1.

On voit sur le dessin que le ressort de fermeture 9 maintient non seulement le clapet 8 de la soupape de purge 7 sur son siège, mais qu'il sert en même temps au maintien en place de la cartouche filtrante 11, de sorte que des mesures particulières ne sont pas nécessaires pour l'ancrage et la fixation de la cartouche sur la tête 1 et dans le récipient 5. On voit également sur le dessin que le ressort 9, le clapet 8 et la plaque de maintien 10 sont formés d'une seule pièce, de préférence en plastique. Ainsi, l'ensemble de l'appareil ne possède qu'un faible nombre de pièces qui peuvent être assemblées simplement, notamment par des machines automatiques, et qui permettent en plus un entretien rapide de l'appareil en service. It can be seen in the drawing that the closing spring 9 not only maintains the valve 8 of the purge valve 7 on its seat, but that it also serves to hold the filter cartridge 11 in place, so that measures particular are not necessary for anchoring and fixing the cartridge on the head 1 and in the container 5. It can also be seen in the drawing that the spring 9, the valve 8 and the retaining plate 10 are formed from a single piece, preferably plastic. Thus, the entire apparatus has only a small number of parts which can be assembled simply, in particular by automatic machines, and which also allow rapid maintenance of the apparatus in service.

En particulier, la cartouche filtrante 11 peut être mise en place et retirée en quelques coups de main. Le vidage du récipient 5 s'effectue par le simple soulèvement du clapet 8 - faisant saillie à l'extérieur de la soupape de purge, ce qui permet au liquide de s'écouler à l'extérieur.  In particular, the filter cartridge 11 can be put in place and removed with a few hand strokes. The container 5 is emptied by simply lifting the valve 8 - protruding outside the purge valve, which allows the liquid to flow outside.
