This filter is characterised in that the snap-on means 7 are distributed on the inner surfaces of the two half-shells 1, 2, on either side of their junction plane.

Description

La présente invention concerne un filtre monobloc contenant un élément filtrant indémontable. The present invention relates to a monobloc filter containing a non-removable filter element.

On utilise couramment des filtres à liquide ou à gaz dans divers domaines industriels, notamment sur les véhicules automobiles, les engins agricoles, les véhicules industriels etc.. Ces filtres sont généralement utilisés pour filtrer l'air d'admission des moteurs, l'huile d'un circuit de lubrification, l'essence d'alimentation du moteur ou encore d'autres fluides. On connaît déjà des filtres monoblocs qui sont jetables dans leur intégralité, lorsque l'élément filtrant est plus ou moins colmaté et n'assure plus sa fonction de filtration. Liquid or gas filters are commonly used in various industrial fields, in particular on motor vehicles, agricultural machinery, industrial vehicles, etc. These filters are generally used to filter the intake air of engines, oil of a lubrication circuit, the petrol supplying the engine or other fluids. One-piece filters are already known which are disposable in their entirety when the filter element is more or less clogged and no longer performs its filtration function.

Certains filtres monoblocs connus comportent un corps de filtre qui est réalisé à partir de deux demi-coquilles en matière plastique soudées l'une à l'autre. Un tel filtre présente toutefois l'inconvénient que son coût de fabrication est relativement élevé. du fait de la nécessité de prévoir une opération de soudage des deux demi-coquilles l'une sur l'autre, le long de leurs bords adjacents. Certain known monoblock filters include a filter body which is produced from two plastic half-shells welded to each other. However, such a filter has the disadvantage that its manufacturing cost is relatively high. due to the need to provide a welding operation of the two half-shells one on the other, along their adjacent edges.

On connaît également d'autres filtres monoblocs dont le corps de filtre est constitué de deux demi-coquilles en matière plastique moulées, qui sont rendues solidaires # une de l'suture par des moyens d'encliquetage externes répartis à la périphérie des deux demi-coquilles. Toutefois les filtres de ce type présentent l'inconvénient qu'ils exigent des moyens de fixation additionnels sur le support du filtre, d'où un coût supplémentaire. Other monoblock filters are also known, the filter body of which consists of two molded plastic half-shells, which are made integral # one with the suture by external latching means distributed around the periphery of the two half shells. However, filters of this type have the drawback that they require additional fixing means on the filter support, hence an additional cost.

La présente invention vise à remédier à ces inconvénients en procurant un filtre monobloc de conception particulièrement simple et d'un bas prix de revient. The present invention aims to remedy these drawbacks by providing a one-piece filter with a particularly simple design and a low cost price.

A cet effet ce filtre monobloc composé de deux demicoquilles enserrait entre elles un élément filtrant et rendues solidaires l'une de l'autre par des moyens d'encliquetage prévus respectivement sur les deux demi-coquilles, est caractérisé en ce que les moyens d'encliquetage sont répartis sur les surfaces internes des deux demi-coquilles. de part et d'autre de leur plan de jonction.  To this end, this monobloc filter composed of two half-shells encloses a filter element between them and made integral with one another by latching means provided respectively on the two half-shells, is characterized in that the means of snap are distributed over the internal surfaces of the two half-shells. on either side of their junction plane.

Le filtre suivant l'invention offre l'avantage qu'il est absolument indémontable du fait que les moyens d'encliquetage sont situés à l'intérieur du corps de filtre. Par ailleurs sa fabrication est notablement simplifiée puisqu'il suffit d'approcher les deux demi-coquilles l'une de l'autre et de les plaquer l'une contre l'autre pour assurer le verrouillage mutuel des moyens d'encliquetage situés à l'intérieur. En outre son apparence externe est améliorée puisque les surfaces latérales externes des deux demi-coquilles ne présentent aucune saillie correspondant à des organes d'encliquetage. The filter according to the invention offers the advantage that it is absolutely impossible to dismantle because the latching means are located inside the filter body. Furthermore, its manufacture is considerably simplified since it suffices to approach the two half-shells one from the other and to press them against one another to ensure the mutual locking of the latching means located at the inside. In addition, its external appearance is improved since the external lateral surfaces of the two half-shells do not have any projection corresponding to latching members.

On décrira ci-apràs,à titre d'exemple non limitatif. We will describe below, by way of nonlimiting example.

une forme d'exécution de la présente invention, en référence au dessin annexé qui est une vue en coupe axiale d'un filtre monobloc suivant l'invention
Le filtre monobloc qui est représenté sur le dessin comprend un corps de filtre externe, qui est constitué de deux demi-coquilles 1 et 2, en matière plastique moulée, assemblées entre elles et qui maintiennent à 3'intérieur un élément filtrant constitué. dans la forme d'exécution particulière décrite à titre d'exemple, par une cartouche filtrante 3 en papier ou tout autre matériau filtrant approprié. Cette cartouche annulaire 3 est solidaire de bourrelets annulaires coaxiaux 4 et 5 prolongeant la surface latérale interne de la cartouche 3.Les bourrelets 4 et 5 sont respectivement en contact avec les fonds la et 2a des deux demi-coquilles 1,2 La cartouche 3 est logée dans son ensemble à l'extérieur de nervures annulaires internes lb.an embodiment of the present invention, with reference to the accompanying drawing which is an axial sectional view of a one-piece filter according to the invention
The monoblock filter which is shown in the drawing comprises an external filter body, which consists of two half-shells 1 and 2, of molded plastic, assembled together and which hold a filter element formed inside. in the particular embodiment described by way of example, with a filter cartridge 3 made of paper or any other suitable filter material. This annular cartridge 3 is integral with coaxial annular beads 4 and 5 extending the internal lateral surface of the cartridge 3. The beads 4 and 5 are respectively in contact with the bottoms 1a and 2a of the two half-shells 1,2 The cartridge 3 is housed as a whole outside of internal annular ribs lb.

2b, venant de moulage, qui s'étendent l'une en direction de l'autre, respectivement à partir des fonds la et 2a.2b, coming from molding, which extend one towards the other, respectively from the bottoms la and 2a.

Les fonds la et 2a délimitent ainsi une chambre dans laquelle est logée la cartouche 3 et ils sont prolongés par des parties semi-tubulaires lc,2c formant un conduit d'entrée du fluide à filtrer lorsque les deux demi-coquilles 1,2 sont assemblées entre elles. Par ailleurs le fond 2a de la demi-coquille inférieure 2 présente, dans sa partie centrale, une ouverture 6 à travers laquelle sort le fluide filtré.  The bottoms 1a and 2a thus delimit a chamber in which the cartridge 3 is housed and they are extended by semi-tubular parts lc, 2c forming an inlet conduit for the fluid to be filtered when the two half-shells 1, 2 are assembled between them. Furthermore, the bottom 2a of the lower half-shell 2 has, in its central part, an opening 6 through which the filtered fluid exits.

Suivant l'invention les deux demi-coquilles 1.2 sont assemblées par des moyens d'encliquetage internes 7. According to the invention, the two half-shells 1.2 are assembled by internal latching means 7.

Ces moyens d'encliquetage internes sont répartis sur les surfaces internes des deux demi-coquilles, y compris sur les parties semi-tubulaires lc,2c.These internal latching means are distributed over the internal surfaces of the two half-shells, including on the semi-tubular parts lc, 2c.

Les moyens d'encliquetage internes 7 peuvent être réalisés de différentes façons. Dans la forme d'exécution représentée à titre d'exemple non limitatif, ces moyens comportent, sur la surface interne de la demi-coquille supérieure 1, une nervure verticale 8 qui se prolonge au-delà du bord inférieur ld de la demi-coquille supérieure 1, par une patte 9 percée d'un trou 10. Avec cette patte 9 coopère un erqot 11 prévu dans la partie supérieure de la surface interne de la demi-coquille inférieure 2. Cet ergot 11 qui vient de moulage avec le reste de la demi-coquille 2, est situé dans une position telle qu'il puisse s'engager, lorsque les deux demi-coquilles 1,2 sont appliquées l'une sur l'autre, dans un trou 10 d'une patte 9 de la demi-coquille supérieure 1.Les trous 10 et les ergots 11 peuvent avoir toute forme appropriée. notamment rectangulaire comme il est représenté sur le dessin. The internal latching means 7 can be produced in different ways. In the embodiment shown by way of nonlimiting example, these means comprise, on the internal surface of the upper half-shell 1, a vertical rib 8 which extends beyond the lower edge ld of the half-shell upper 1, by a lug 9 pierced with a hole 10. With this lug 9 cooperates an erqot 11 provided in the upper part of the internal surface of the lower half-shell 2. This lug 11 which comes from molding with the rest of the half-shell 2, is located in a position such that it can engage, when the two half-shells 1,2 are applied one on the other, in a hole 10 of a tab 9 of the upper half-shell 1. The holes 10 and the pins 11 may have any suitable shape. especially rectangular as shown in the drawing.

Pour la fabrication du filtre monobloc suivant l'invention, il suffit par conséquent, après avoir mis en place la cartouche filtrante 3 sur la demi-coquille inférieure 2, dans la position appropriée tout autour de la nervure annulaire interne 2b. de coiffer l'ensemble avec la demi-coquille supérieure 1 et de serrer l'une contre l'autre les deux demi-coquilles de manière à faire glisser les pattes 9 sur les ergots 11 jusqu'à ce que ceux-ci s'engagent et se verrouillent définitivement dans les trous 10 des pattes 9. A partir ce moment il est impossible de séparer l'une de l'autre les deux demi-coquilles 1,2. For the manufacture of the one-piece filter according to the invention, it is therefore sufficient, after having installed the filter cartridge 3 on the lower half-shell 2, in the appropriate position all around the internal annular rib 2b. to cover the assembly with the upper half-shell 1 and to tighten one against the other the two half-shells so as to slide the tabs 9 on the lugs 11 until they engage and lock themselves definitively in the holes 10 of the legs 9. From this moment it is impossible to separate one from the other the two half-shells 1,2.

Suivant une variante les moyens d'encliquetage 7 pourraient comprendre, sur l'une des demi-coquilles 1,2, une patte formant crochet, cette patte venant s'agripper derrière une butée approprie prévus sur l'autre demi-coquille.  According to a variant, the latching means 7 could comprise, on one of the half-shells 1,2, a tab forming a hook, this tab coming to grip behind an appropriate stop provided on the other half-shell.
