Definitions

  • the present invention relates to liquid ⁇ atomizers comprising a piston pump mounted on a reservoir and wherein the piston moves on its suction stroke under the action of a -return spring.
  • the invention is more especially, but not exclusively concerned with atomizers of this kind wherein the pump, disposed in the plug of a container, carries above it a push-piece the driving in of which produces the liquid delivery stroke of the piston.
  • the chief object of the present invention is to provide an atomizer of this kind which is better adapted than those known up to this time to meet the requirements of practice.
  • the chief feature of the invention consists in closing the air intake of the reservoir, while stopping the passage through which the cylinder communicates with the delivery conduit leading to the atomizing nozzle by means of the piston of the pump when it is in its position of rest.
  • the portion of the inside of the cylinder which is located at the end thereof toward which the piston is urged by its return spring belongs to the air intake conduit of the reservoir and is of aring shape so that said air intake conduit is closed and the piston is not radially compressed when the piston is in its position of rest for which it is located in this porton of the cylinder.
  • a suction valve which opens only when there is produced, in the reservoir, a subatmospheric pressure due to the suction of the pump.
  • the piston rod extends axially through the cylinder and slides with a snug tit in a packing ring ⁇ disposed at the end of the cylinder and yforming a suction valve.
  • FIG. 1 is an axial sectional view of a portion of an atomizer made -according to a first embodiment ⁇ of the invention, the piston of the pump being at the end of its upward stroke;
  • FIG. 2 is a view similar to FIG. 1 but showing the piston at the end of its downward stroke
  • FIGS. 3 and 4 are views, similar to FIGS. 1 and 2 respectively, showing another embodiment of the invention.
  • the atomizer illustrated by the drawings is secured in a liuidtight manner on the neck 1 of a container.
  • the plug of the ⁇ atomizer contains an axial cylinder 2 in which is slidable a piston 3 connected through a rod 4 with a push-piece 5 located above the plug.
  • piston 3 In cylinder 2, piston 3 is urged upwardly by a return spring 6.
  • Piston 3 in its position of rest, closes, on the one hand, the air intake 7, 8 of container 1 and, on the other hand, passage 9 through which delivery conduit 10 communicates with cylinder 2.
  • the upper end of cylinder 2, toward which piston 3 is urged by return spring 6 belongs to the air intake conduit of container 1, whereby this conduit is closed when piston 3 is in its position of rest.
  • the inlet orifice 7 of the air intake of container 1 consists of an opening provided in the closure piece 21 of cylinder 2, through which opening extends the control rod 4 of piston 3.
  • the diameter of said rod 4 is smaller than that of said opening in closure piece 21, whereby intake orifice 7 is ⁇ of annular shape.
  • the diameter of said perennial 7 is smaller than the diameter of piston 3 so that when said piston is applied against closure piece 21 by spring 6 it closes orifice 7.
  • delivery conduit 10 is located in rod 4 and communicates with passage 9 through which the liquid delivered by the pump reaches atomizing nozzle 11.
  • piston 3 is made of a iiexible and resilient material, such as rubber, polyethylene of the like, and it comprises, below the portion that cooperates with the wall of cylinder 2, a skirt 3, covering passage 9 in rod 4.
  • Skirt 31 thus plays the part of a delivery valve, controlled by the displacements of piston 3 in cylinder 2.
  • the opening and the closing of said valve are thus made independent of the pressure existing in cylinder 2, which makes the operation of the pump safer and its actuation less diiiicult.
  • rod 4 carries, beyond piston 3, in the downward direction, a rod 12 which extends axially into cylinder 2 and the free end of which is engaged with some clearance in a conduit 13 coaxial with cylinder 2 and in line therewith, forming a connection with Idipping tube 14.
  • a rigid ring 15, surrounding rod 12 and applied by spring 6 against the lower end of cylinder 2 covers ⁇ an annular cavity 16 provided at the bottom of cylinder 2 and communicating with conduit 13.
  • a packing ring 17 mounted slidable on rod 12 is housed with some play in annular recess 16. This ring 17 acts as a suction valve which is applied against the inlet of conduit 13 by rod 12 when piston 3 moves downwardly in cylinder 2.
  • the atomizer of FIGS. 1 and 2 works in the following manner.
  • Push-piece 5 is -moved downwardly. Piston 3 clears air intake 7, 8.
  • piston 3 When push-piece 5 is released piston 3 is moved upwardly in cylinder 2 by return spring 6. At the beginning of this movement the skirt 31 of the piston, coming back upon conduit 9, stops delivery Iconduit 10, whereas rod 12 lifts ring 17 slightly away from the top of conduit 13. The liquid present in container 1 is thus sucked through tube 14, conduit 13 and recess 16, owing past ring 15 through a notch 151 provided in the periphery of said ring. The above described cycle of the pump may then be repeated by driving push-piece 5 downwardly.
  • the atomizer When the operation is finished, the atomizer is automatically closed in a fluidtight manner by piston 3 which on the one hand stops the air intake by being applied against the edges of openings 7 and 8 and, on the protect push-piece 5 is reother hand, has its skirt 31 applied against the oriiice of conduit 9 which leads to nozzle 11.
  • the piston 18 of the pump is slidable along control rod 4a, so that it can be moved between two abutments 19 and 20.
  • the air intake 8a of the container opens on the external wall of cylinder 2a through an opening 21 covered by a resilient sleeve 22, for instance of rubber, slipped on cylinder 2.
  • sleeve 22 is rigid with the packing joint 23 of the plug which may be fixed on the container (not shown) in any suitable known manner, for instance by screwing, setting or the like.
  • This embodiment has the vadvantage that air intake 8a and opening 21 may consist of mere grooves provided in cylinder 2 and covered by packing joint 23 and sleeve 22.
  • sleeve 22 opposes any .passage of air or liquid in the opposed direction.
  • the upper end of cylinder 2 or 2a is advantageously given a flaring shape such as shown at 24 and 24a, respectively, so as to free the piston, in its position of rest, from any radial pressure in order to protect it against any deformation which might reduce its liquidtight iit in the cylinder.

  • a piston of a exible and resilient material slidable in said cylinder to form therewith a pump chamber of variable volume
  • conduit means for connecting the inside of said container with said pump chamber
  • push-piece means rigid with said rod for driving said piston in a second direction toward its position in said cylinder where said pump chamber has its minimum volume
  • valve means for closing said conduit means in response to the movement of said piston in said second direction
  • said rod being provided with a longitudinal conduit leading at one end to said atomizing nozzle and the other end of which opens into the outer surface of said rod through an orifice,
  • a deformable skirt carried by said piston adapted to -control said orifice to close it when said piston is moving in said first direction land to clear it when said piston is moving in said second direction, and
