Definitions

  • the present invention relates to a mixer of liquids, particularly for the distribution of detergents for washing motor vehicles or for the distribution of fertilizers, anticryptogamics, etc. for gardening purposes.
  • mixers In order to assist the operator, mixers have already been thought up which, inserted in a hydraulic circuit, are capable of ensuring the two deliveries, automatically performing the mixing operation, when requested.
  • the object of the present invention is to accomplish a mixer which, in addition to the normal delivery of water only and to the mixing of water and detergent, also allows the delivery of detergent only.
  • a further object is to provide this mixer with the possibility of varying the concentration of detergent from a maximum to a minimum, as well with a position in which the mixer itself behaves like a closed cock without having recourse to the main cock with its corresponding inconvenient access.
  • a mixer for liquids comprising a housing provided with an inlet opening and with an outlet opening for a main liquid, said housing having means for fastening a container of an auxiliary substance to be mixed with said main liquid, and a valve element arranged between said inlet opening and said outlet opening, characterized in that said valve element has a first drilled portion such as to allow the direct communication between said inlet opening and said outlet opening for a first angular position of said valve element and the closing of said communication for a second angular position of said valve element, and a second axially displaced portion comprising at least two diametrically opposed holes communicating on one side in a constant manner with respective coaxial channels arranged in said valve element and in their turn communicating with said container and on the other side with said inlet and outlet openings for a third angular position of said valve element wherein said first portion of the element itself accomplishes a reduced direct communication between said inlet opening and said outlet opening and a
  • the mixer is constituted by a housing 1 provided with an inlet opening 2 and with an outlet opening 3 for a main liquid, say, water.
  • a container 6 for an auxiliary substance, say, liquid detergent to be mixed with the main liquid.
  • auxiliary substance say, liquid detergent
  • valve element 7 which may be moved by rotation.
  • Said valve element 7 (Fig.s 14 and 15) comprises a first drilled portion 8 delimited by two walls having an annular sector 15 and a second axially displaced portion 16 comprising two holes 9 and 10, communicating with respective axial channels 11 and 12 and having a cross-section which decreases in the direction of the latter, which in turn communicate with said container 6.
  • the valve element 7 has an upper appendix 30 which protrudes from housing 1 and with which there is integral a shaped roller 17 for the operation of the valve element itself.
  • the inlet opening 2 and the outlet opening 3 also have respective threads 18, 19 for the connection to a hydraulic circuit.
  • the mixer may be connected to a water mains by means of threads 18 of inlet opening 2, while a union for a rubber hose may be applied to outlet opening 3.
  • the mixer is supplied with water which, according to the angular position of valve element 7, may follow different paths before arriving at the outlet opening 3.
  • valve element 7 (Fig.s 2-­4), which may be defined as for water only, the drilled portion 8 is aligned with inlet opening 2 and outlet opening 3 so as to allow direct communication between them, so that water flows through the mixer without affecting the substance contained in container 6.
  • valve element 7 (Fig.s 5-7), which may be defined as the closed position, the mixer behaves like a closed cock, since in this angular position the annular walls 15 are arranged transversally to inlet opening 2 and to outlet opening 3.
  • Fig.s 8-10 may be defined as the mixing position, wherein, supposing that the substance to be mixed is detergent for washing motor vehicles and a water-detergent mixture is required, water not only flows through the drilled portion 8 but also flows into hole 9 and from here to the corresponding axial channel 11 and thence to container 6, from which after mixing with the detergent is exits through axial channel 12 and the corresponding hole 10 to arrive at outlet opening 3.
  • notching 13 connected with hole 9 allows the variation of the quantity of water which may arrive at container 6.
  • the cross-section of hole 9 offering a passage to the water is more or less important, so as to define a corresponding more or less important quantity of water which is allowed to reach the container 6 and, as a consequence, a variation of the concentration of the water-detergent mixture at the outlet of the mixer.
  • hole 10 and notching 14 which alter the oulet cross-section of the detergent.
  • valve element 7 Fig.s 11-13
  • a fourth position of valve element 7 Fig.s 11-13
  • Fig.s 11-13 which may be defined as a "shampoo" position
  • the direct communication between inlet opening 2 and outlet opening 3 is prevented by the walls 15 as in the closed position, while water may enter hole 9 and from here flow to axial channel 11 exerting pressure on the detergent, which is forced to flow in axial channel 12 and from here into hole 10, from where it exits in the form of just detergent, diluted only to a very small extent.
  • This could prove useful, say, in the case of a requirement of an initial abundant soaping with a high detergent concentration.
  • any other substance may be used which may be mixed with water or other liquid, such as fertilizers and/or anticryptogamics for gardening purposes.
  • the mixer accomplished according to the present invention will be able to operate at any of its positions; in actual fact, by using water pressure to convey the substance to be mixed, it shall be indifferent whether the mixer is in a direct position as represented in the drawings or in an upside down position or otherwise at an angle.
