Definitions

  • This invention relates to a plug with retaining and sealing packing for a water faucet cartridge.
  • a water faucet cartridge contains operating parts including means for the control of water flow and handling members and is intended to be inserted in a removable and leak-proof fashion in the cavity of a water faucet body connected to pipes.
  • a cartridge permits easy and rapid replacement of operating parts when they have broken or when they have become worn out.
  • the cartridge has a packing which, when the cartridge is inserted into the body of the faucet, establishes a sealing hold with respect to the bottom of the cavity of the faucet body.
  • the plug also establishes a sealing hold with respect to an internal member that is a part of the means which control the water flow such as, for example, a fixed plate made of hard material which cooperates with a mobile plate that is operated by the handling members.
  • One object of this invention is to provide a plug with retaining packings for a faucet cartridge which, in addition to permitting the application of different assembly compressions on the two sides of the plug, also ensures that the packings cannot be deformed or expelled from their seats even under maximum pressures or foreseeable pressure surges, and to substantially facilitate the mounting of the cartridge by automatic equipment.
  • the packing is made in one piece on both sides of the plug.
  • the portion of the packing that is on one side of the plug and the portion of the packing that is on the other side of the plug have a portion of their surfaces resting against the plug with respect to the axial direction of the plug and linked to each other by at least one connecting portion that extends primarily in the axial direction.
  • the packing is molded on the plug by injecting an elastomer in the liquid state and then cross-linking it.
  • both portions (upper and lower) of the packing are able to accept the necessary assembly compression from the plug against which a part of their surface rests.
  • the packing is positively anchored at the bottom of the cartridge and the link between the two portions of the packing that are on the two sides of the plug ensures that the portions themselves cannot be deformed or expelled from their seats even when subjected to high stresses which are within the breaking strength of the material of which the packings are made.
  • the packings can be made of an elastomer having high yield characteristics, which is an advantage to the faucet's proper performance.
  • packings by an injection procedure makes it possible to obtain the desired configurations, which in many cases could not be achieved in any other way and which would otherwise involve complex operations. It is possible to provide packings with certain configurations that could not have heretofore been achieved in a convenient fashion or that would have made the packings themselves excessively delicate. In particular, it is possible to provide the packing shapes that exhibit differences in extension in various directions, and shapes that are considerably different on the two sides of the plug. It is also possible to provide packings that are so resistant that they are not limited to operating only statically with operationally immobile parts, but can function properly with an operationally mobile part such as a stopper. This makes it possible to produce cartridges with a simpler and more economical structure.

  • Figs. 1 and 2 show a plug with prior art packings.
  • the reference numeral 1 indicates the bottom of a faucet body cavity containing passages for water. The remaining parts of the faucet body are not shown, because they are of no relevance to this invention.
  • the reference numeral 2 refers to the bottom of a cartridge and the reference numeral 3 refers to a fixed distribution plate made of hard material constituting a part of the flow control means in the cartridge. The other parts of the cartridge are omitted in Figs. 1 to 15 because they are of no_concern to this invention.
  • prior art packings 4 are inserted through openings in plug 2 to connect corresponding passages in the bottom 1 of the faucet cavity and in fixed plate 3 providing a seal between both of these parts. In this case it is not possible to apply different assembly compressions between packings 4 and bottom 1, and between packings 4 and fixed plate 3, as is often required.
  • FIG. 3 shows one embodiment of a plug with the packings anchored in accordance with the present invention.
  • a sealing packing that has an inferior portion 7 and a superior portion 8. Both portions are linked by a portion 9 that extends axially through the opening of plug 2.
  • the inferior portion 7 and the superior portion 8 have projections 10 and 11 that are disposed in corresponding cavities of plug 2.
  • Both the inferior portion 7 and the superior portion 8 of each packing have a large portion of their surface abutting against plug 2 of the cartridge. Because of this these portions receive adequate compression between plug 2 and bottom 1 of the faucet body cavity for portion 7 and between plug 2 and fixed plate 3 for portion 8. This is why the mounting compressions applied to portions 7 and 8 of the packing can be different.
  • neither portion 7 nor portion 8 of the packing is deformed to the outside nor ejected from its seat because it is positively retained in its seat by the link through portion 9 with the other portion 8 or 7.
  • projections 10 and 11 when inserted in corresponding cavities in the plug they also collaborate in this positive retaining action. Projections 10 and 11, when present, can be continuous, they can be ring-shaped, or they can exist only in sections.
  • the embodiment illustrated in Fig. 4 is extremely similar to the embodiment illustrated in Fig. 3 from which it differs only by the presence on the lower portion 7 and on the upper portion 8 of peripheral projections 12 and 13 which are inserted in corresponding cavities of plug 2.
  • These projections similar to projections 10 and 11 (which they can replace), cooperate in anchoring the packing to plug 2.
  • These projections can also be continuous, ring-shaped, or in sections.
  • peripheral projections 12 and 13 of the embodiment illustrated in Fig. 4 are replaced by portions 14 that extend through the cavities of plug 2, connecting portions 7 and 8 of the packing to each other. It is readily apparent that portions 14 cannot extend continually along the entire periphery of the packing and must be in sections that can be made in any number and any extent. Another embodiment of the portions in sections extending through the plug is shown in cross-section in Fig. 13. Portions 14 can also replace portion 9 instead of being an addition thereto. It is obvious that such an embodiment could not be produced except by the injection procedure of the instant invention.
  • the packing still has inferior portion 7 and superior portion 8 that have a part of their surfaces abutting against plug 2 and a connecting portion 9 that extends axially.
  • portions 7 and 8 are also peripherally anchored to plug 2 due to their toothed configuration, as illustrated in Fig. 7.
  • the peripheral teeth of these portions can also be configured in an undercut fashion.
  • a similar embodiment can be provided without the peripheral teeth.
  • a rigid bushing 15 can be inserted inside connecting portion 9 of the packing.
  • the bushing illustrated in Fig. 6 and labeled 15 instead of being a separate, rigid, inserted bushing, can be a part of plug 2 and in such case connecting portion 9 need not be continuous but can be made in sections and can extend through corresponding openings in plug 2, as described above in conjunction with the embodiment illustrated in Fig. 5 and as substantially illustrated in Fig. 13.
  • Figs. 8 and 9 illustrate how a plurality of packings of the type described in the preceding embodiment (which in this embodiment do not have any peripheral teeth) can be made during the injection procedure, providing for a single injection region 16 that communicates with portions 8 of all or part of the packings of plug 2. It is, however, possible to have several common injection points when expedient by the injection technique.
  • inferior portion 7 and superior portion 8 are connected to each other by connecting portions 20 which, in contrast to connecting portions 9 discussed earlier, are not continuous but are made up of sections and go through corresponding passage openings in plug 2 similarly to the peripheral connecting portions 14 illustrated in Fig. 5. Packings that have this configuration can also only be made by the injection procedure of this invention.
  • Fig. 14 illustrates a modification of the embodiment illustrated in Fig. 12.
  • superior portion 38 of the packing is shaped like a lip. Due to this configuration the packing assumes a "hydraulic effect" since its contact pressure with respect to fixed plate 3 is determined not only by the mounting compression but also by the pressure exerted on lip 28 by the water. In this way, the contact pressure increases as water pressure increases, automatically adapting to it so that the mounting compression, which represents the minimum contact pressure of lip 28, can be set at a lower value. It is, of course, to be understood that where considered advisable inferior portion 7 of the packing can also be made in the form of a lip similar to superior portion 28.
  • Fig. 15 illustrates another embodiment of the invention.
  • Certain conventional cartridges are provided with lower connections that extend into seats formed in the bottom of the faucet body cavity, providing a sealing hold by means of packings applied to the connections and receiving a water thrust that depends on the water pressure and, if applicable, on the pressure of a spring.
  • packings applied to the connections and receiving a water thrust that depends on the water pressure and, if applicable, on the pressure of a spring.
  • each of the packings of the plug is basically of the type shown in Fig. 5, but its inferior portion 7 extends peripherally to form a sleeve 27 and rests against the inferior portions 7 of the packings.
  • This embodiment illustrates how the invention can be used advantageously to facilitate the production of certain special cartridges for faucets and make them more economical .
  • the cartridge for a mixing faucet shown in these figures comprises a shell 30 with a perimeter wall 31 to which is connected a plug 32 with the interposition of a packing 29.
  • a supporting ring 33 In the upper part of shell 30 is rotatably mounted a supporting ring 33 on which is pivoted a lever 34 coupled to a slide 35.
  • This slide has a flat stopper 36 that can be made of, for example, inoxidizable steel.
  • the stopper 36 has passage openings that communicate with each other in the inside space of slide 35. Stopper 36 is intended to cooperate directly with packings formed on plug 32.
  • superior portion 8 of a packing for an outlet opening can be circular
  • superior portion 38 of the packings for the inlet openings have, for example, a "banana" shape or the like which permits flow control that is much more accurate than the one attainable with circular inlet openings.
  • Packings having this shape made in the traditional and conventional fashion would be readily broken by stopper 36 when it moves from a position of occlusion (Fig. 16) to a position of complete admission (Fig. 17) passing through intermediate positions (Fig. 18).
  • the effective anchorage of the plug of the packings of this invention enables packings having this shape to operate properly in contact with the mobile stopper without being dislocated or deformed.
  • inferior portions 37 of the packings for the inlet openings need not have a shape different from a circular shape, they can have a circular shape and can be connected to banana shaped superior portions 38 through connecting walls 39. All the packings and packing portions 7, 8, 37, 38, 39 and 29 of plug 2, or part of them, can be made collectively from a single injection point 16 (or from several common injection points) and through ducts 18, as discussed earlier in connection with Figs. 8-11. Finally, reinforcing bushings 15 can be introduced into packings 7-9 and 37-39.
  • a cartridge such as the one shown in Figs. 16-19 offers performance that substantially corresponds to those of a similar cartridge employing a pair of plates made of hard material, one fixed and one mobile, and is considerably less expensive and less bulky.
