Definitions

  • the invention has for its object to overcome these drawbacks and to this end, is directed to a device com-prising a reservoir provided with a well or sump in which is fitted the lower portion of a pump which is introduced through the opening of the reservoir and closes off the said reservoir, the said pump being constituted by a barrel containing an electro-m-agnetic coil which produces the displacement of a hollow piston inside a central bore of the barrel, the said central bore being open at one extremity thereof and coupled at the other extremity thereof to the delivery circuit, the said piston being provided with a regulating v-alve at the delivery end.
  • the well otters the double advantage of being able to localize any possible impurities in the bottom portion thereof and to hold the largest volume of liquid in the reservoir proper, so that the differences of level are not very substantial during use.
  • the filling of the reservoir is carried out simply by withdawing the pump whichcan at the same time either be cleaned or inspected.
  • the barrel thus simply plays the part of a plug for the reservoir.
  • the piston is preferably driven by the coil for the delivery stroke and returns downwards as a result of its own weight in the case of the suction stroke. There is thus produced a free and rapid delivery, whereas the suction can take place at a lower rate of speed and does not require as a result any special system of control.
  • the central bore has .a larger diameter at the open end and terminates in a seating provided with lateral openings, the said seating being for example toothed, and providing a housing for a suction valve.
  • the said seating When made to rest on thebottom of the reservoir, the said seating allows the liquid to pass through while retaining any impurities liable to be present.
  • the largest diameter of the bore permits a free movement of the piston, this latter only applying friction in that portion in which the said friction is useful for effecting the delivery.
  • the valve which closes when the piston returns to its position of rest ensures that the same quantity of liquid always passes out at the delivery end irrespective of the level in the reservoir.
  • the parts which constitute the pump and the reservoir are all made of plastic material or coated with plastic material. It will in fact be understood that it is extremely easy to embed the electro-magnetic coil, as well as the metallic portion of the piston which forms the magnetic armature,
  • FIG. 1 is a partial cross-section at right angles to the cross-section in accordance with FIG. 1.
  • FXGURE 3 is a top view of the windshield-washer device.
  • a reservoir 1 designed to supply the windshield-washer device of an automobile vehicle.
  • This reservoir can be made, for example, of a translucent plastic material.
  • Its main cylindrical chamber 2, which is preferably ribbed, is extended at the bottom portion thereof by a well 3 having a shouldered portion 4 so as to be more closely adapted to the shape of the pump which will be described below and so as to ensure sufiicient rigidity.
  • the reservoir is also provided at 5 with a top opening for the introduction of the liquid, the said opening being closed in the position of use by the pump proper which is designated by the general reference 6 and constituted by a barrel, the body 7 of which is provided with a bore 8 of small diameter and having at the bottom portion thereof an extended bore '9 of larger diameter which is provided at lit] with an internal shouldered portion.
  • an electro-magnetic coil 13 encased inside an outer body 14, the lower portion of which is adapted to fit over the bore 9 and the upper portion of which is adapted to fit over the bore 8.
  • the body 14 is further provided with suitable overthicknesses so as to encase also the conductors l5 and 16 for the supply of current.
  • a plug 17 which is designed to close the opening 5 while leaving a passage for air, this annular plug containing the two tubular delivery pipes 18 and 19 which are each coupled to one of the windshield-washers of the automobile vehicles, and which open into the bore 8.
  • the body 7 rests at the bottom of the well 3 on a toothed seating 20 which allows the liquid to flow towards the suction valve 21, the head of which moves between the shouldered portion 1'5 and the seating 22.
  • the piston 23 which is constituted by a metallic tube 24 coated with a suitable plastic material and provided with an internal passage 25, moves in the interior of the bore 8. It will be observed that there is a substantial clearance between the piston 23 and the wall of the bore 8.
  • the piston 23 is freely movable within the bore 8 so that it can be moved upwardly substantially instantaneously when the coil 13 is energized and it will quickly move downwardly under its own weight when the coil is de-energized.
  • This clearance also enable some of the fluid in the bore 8 to move downwardly into the bore 9 when the piston 23 is being moved upwardly so that an excessive pressure is not created in the bore 8.
  • the delivery valve 26 which has a conical seating and in the body of which are formed recesses 27 for the circulation of fluid.
  • a cap 28 which is open at its top extremity covers the piston 23 and ensures the guiding of the valve 26.
  • the piston returns downwards by virtue of its ownweight and the liquid which is contained inside the bore 9 as'a result ofthe closure of the valve 21 flows into the bore 8 through the passage 25 and the valve 26.
  • the inner. body 7fand the outer body 14 of the barrel can easily be made of plastic position when the operations are com- I material, the body 7 by moulding and the body 14 by q the said form of embodiment without thereby departing from the scope or the spirit of the present invention.
  • This' single pipe can be coupled,'for example, by means of a flexible pipe to the inlet pipe of asiphon which isencased within the body of the pump and extends over at least that portion which corresponds to the main chamber of the reservoir.
  • the outlet pipe of thesiphon is'thenvv coupled to the windshield-washer'of the vehicle.
  • said pump body having arcentral bore extending from one end to the other end thereof, theupper end of said bore communicating with'said second passageway means and the bottom end of said bore being in communication.
  • an elongated, tubular piston slidably disposed in said borev for movement between, a first position remote from said upper end of, said bore and a second position adjacent to said upper end of said bore, said piston being of an appreciably 'smaller size than said bore with a: substantial clearance existing therebetween so that said piston is freely movable along said bore;
  • a valve mounted on said piston at the upper end thereof for closing off the central opening in said piston when, said piston ismoving from said first to said second. position whereby fiuid'in said bore between saidpiston and saidsecond passageway means will be discharged through said second passageway means, said valve being open when said piston is moved from said second to said first'positionwherebyliquidcan travel from saidwellthrough said piston and into said'bore between saidpiston and said upper. end of said.bore,fsaid plug, said pump body and the parts therewithin being removable as a unit from said reservoir through'said outlet opening.
  • first way means comprises a passage" extendingthrough said pipe and'through'the bottom of the plugwhereby washing liquid pumped from said bore when said piston moves 1 from said first to'said second position will be'conducted passageway means therethrough forcon'du'cting'the .1
  • wires and second passageway means therethrough for, conducting washing liquid out from said reservoir; an'elong'ated cylindrical well extending downwardly from the said lower end wall of said reservoir and.
