Definitions

  • the present invention refers to a filter for taps, whose obvious purpose is to prevent the passage of certain foreign objects immersed in the flow of fluid that accesses a faucet, and prevent with it possible anomalies in the operation of the tap itself.
  • the object of the invention in addition to filtering foreign bodies that access a tap, is to reduce the speed of the incoming fluid, thereby reducing the volume of water per unit of time and thereby achieving optimum and efficient operation of the tap .
  • the filter of the invention although it can be applied to conventional taps and valves, is preferably intended for concrete application to toilet tank filling taps.
  • the filter of the invention is characterized by having a general configuration cylindrical determined by a rectangular body of small thickness, in which two flat and contiguous sections, slightly out of phase, are established, presenting the first section, considered as anterior, and on both sides, a plurality of fins perpendicular to the face but with oblique arrangement with respect to the longitudinal axis.
  • Fins that have the shape of a right triangle with the side corresponding to its curved hypotenuse, the greater leg being attached to the plane of the rectangular body, while the smaller leg is perpendicular to that plane and in proximity to one of the edges of the commented Rectangular body, the fins being arranged alternately opposite each side and offset between them of one face with respect to the other, to jointly determine a labyrinth passage that allows reducing the speed of the fluid in that first section of the filter.
  • the other section established after the aforementioned, has semicircular fins on both sides, perpendicular to them and facing each other, to determine partitions in the form of transverse discs, these being on its periphery equipped with battlements that determine small steps for the filtering of the circulating fluid and coming from the first labyrinthine section.
  • the filter thus constituted is mounted axially inside the access duct to the tap in question, being correctly positioned based on projections provided on the sides of the flat body, in combination with projections established on the fins of the first section.
  • the flat body of the filter has the free end corresponding to the first section, an axial and central extension determining a grip element to allow the extraction of the filter and carry out the corresponding or cleaning.
  • Figure 2. Shows another general perspective of the same filter seen, in this case, from the opposite side.
  • FIG. 3 Shows a side elevation of the filter shown in the previous figures.
  • Figure 4.- Shows a plan view of the same filter of the previous figures.
  • Figure 5. Shows a front view, by the end of the axial grip extension, of the filter of the invention.
  • the filter of the invention has a general cylindrical configuration for its axial and concentric arrangement in the fluid inlet conduit to the corresponding tap in which it is applied.
  • a plurality of fins 3 perpendicular to such faces are provided, offset from each other on one side with respect to the other, and in oblique arrangement, the fins 3 presenting the shape of a right triangle, one of whose sides or legs 4, which is the longest, is attached to the plane or face of section 1, while the other side or leg 5 is perpendicular to the face and distanced from the edge corresponding to the flat and rectangular section 1 itself.
  • These fins 3 of each face are alternately positioned opposite, the side 6 corresponding to the hypotenuse of each fin 3 of curved profile, with a protrusion 7 at its highest point.
  • the fins 3, determine a labyrinthine section that causes the flow of circulating fluid to lose speed. That is, said section 1, as a section before the direction of fluid circulation, acts as a speed reducing means.
  • section 2 has a plurality of semicircular fins 8, perpendicular and in opposition to those of one face with respect to those of the other, determining discoid and transverse partitions, said partitions being affected by battlements 9 of different amplitude or depth to determine together that said section 2 acts as a means of filtering the flow, following the speed reducing section 1.
  • the filter thus constituted is correctly positioned axially and centered on the corresponding fluid inlet conduit to the respective tap in which it is applied, by counting the lateral edges of section 1 with projections 10 that contact the internal surface of said conduit , in combination with the projections 7 of the fins 3.
  • the free end corresponding to the section 1 has a central and axial extension 11 determining a gripping means for the extraction of the filter with respect to the conduit in which it is positioned, thereby allowing the corresponding cleaning to be carried out.

Abstract

L'invention concerne un filtre destiné à être monté dans le conduit d'accès à un robinet et appliqué, de préférence, dans des réservoirs pour éviter le passage de corps étrangers et pour réguler le débit de fluide entrant, réduisant le volume fluidique par unité de temps. Le robinet est constitué d'un corps rectangulaire de faible grosseur, avec deux parties différenciées: une première partie (1) pourvue sur ses deux faces d'une pluralité d'ailettes obliques (3), celles d'une partie étant décalées par rapport à celles de la partie opposée, et celles de chaque face étant disposées en alternance de façon contraire, déterminant ensemble un passage en forme de labyrinthe qui permet de réduire la vitesse du fluide circulant dans ladite première partie (1) du circuit. L'autre partie (2), consécutive à la précédente, est pourvue dans ses deux faces d'ailettes semi-circulaires (8), celles d'une face étant opposées à celles de la face opposée et disposées de manière perpendiculaires au plan et à l'axe longitudinal du corps rectangulaire. Lesdites ailettes semi-circulaires (8) présentent au niveau de leur bord des dentelures (9) définissant des petits passages pour le fluide circulant et provenant de la première partie (1). Lesdites dentelures (9) constituent un moyen de filtrage pour éviter le passage de corps étrangers de petite taille.
