Definitions

  • the present invention relates to pumps and accessories for spraying fluid.
  • vapor-piston pumps does not have a threshold pressure from which spraying begins. At the start and end of the operation, a thin stream of unsprayed liquid comes out.
  • the valve moves, for opening, in the opposite direction to the direction of expulsion, so that there is a uniform spraying throughout the operation. .
  • the doses of liquid sprayed are irregular due to the imposition sibility of the control of the differential movement of the pistons, which are always at least two in number, which movement is a function of the component resulting from the force, the pressing speed and the force of the spring; the way to reduce the differences in spray volumes is to strengthen the spring, but a too strong spring is contraindicated for ease of use.
  • pumps have a large number of parts, which causes difficulties in molding, assembly and affects the cost price.
  • pumps with several pistons increase the risks of leaks as well as the friction of the elements in contact.
  • the present invention provides an overcompression pump comprising a reduced number of parts and operating by accumulation of the pressurized liquid growing in an axially expandable chamber.
  • the invention also relates to a diffuser as claimed in claim 9.
  • the expandable chamber determines a small amplitude displacement of the shutter (such as a needle) allowing the expulsion under pressure of the liquid, which has the effect of greater equality between the doses, regardless of the manual support speed.
  • the spring ensures, at the same time, a positive support of the shutter on the valve seat with which the diffuser is provided, thereby sealing the chamber created between said diffuser and the face of the membrane.
  • the piston, the tube, the membrane and the fixing ring are made of a flexible material such as polyethylene.
  • the outer body 1 is made of a rigid material, such as polypropylene or polyethylene; it comprises the chimney 2 provided on the upper side with an internally oriented flange 3 and the groove 5 located at the base of the bore 4 forming compartment 65.
  • the chimney is integral with the projection 6 and the flange 7 whose lower faces are located in the same plane.
  • the lower edge of the projection 6 is integral with the cylindrical sector 8 (bore 8a) and provided with the lateral opening 18, said sector being connected, in turn, to the cylindrical sector 10, this by means of the frustoconical sector 9.
  • the sector 10 comprises the bore 11, at the base of which is the shoulder 12 provided in its center with the sealing lip 13 forming an inlet; the same sector 10 also includes the bore 14 forming the cavity 15 and the bore 16 in which the dip tube 17 is placed.
  • the bores 4, 8a, 11, 14 and 16 are coaxial and the sectors 2, 6, 7, 8 and 10 constitute a single part produced in a single molding, in the same material.
  • the piston holder 19 comprises, on the lower side, the single piston 20 provided at its center with the bore 21 resting on the shoulder 22 which communicates with the central channel 23 of the tube 26.
  • the tube 26 serves as an intermediate element for connect the piston 20 to the membrane 24 and to its fixing ring 25 and it is also provided, on its outer wall, with the vertical groove 27.
  • the diffuser 28 has at its base a collar with a markedly greater diameter 29 and the axial bore 58 in which the groove 30 is formed; the said bore is overhung by the coaxial bore 31, which communicates with the nozzle 35 via the channels 32 and 33, the channel 23 being provided at its base with the valve seat 34.
  • the central member 36 is made integral with the piston holder 19; its splined hub 39 being placed in the bore 21 and its rod 54 - provided with the vertical groove 38 and the needle 37 - in the bore 23 of the tube 26.
  • the pump also comprises the element 45 provided with the annular seal 44 which cooperates with the external face of the tube 26, this element being snapped into the groove 5 which is provided with the bore 4.
  • the chimney 2 and its flange 3 are made elastic by the slots 2a, 2b, 2c, 2d and 2f ( Figure 2).
  • the cavity 52 is formed, delimited between the shoulder 55 of the bore 58 and the upper face of the membrane 24, which cavity is sealed thanks to the needle 37 and the fixing ring. 25 in the diffuser 28.
  • the assembly is capped with the sleeve 47 provided with the internal thread 48.
  • the compartment 65 does not communicate with the chambers 52 and 56.
  • the rod 41 is provided on the inner side with at least one notch 62 of small axial height allowing the compressed air to escape into the container.
  • the needle 37 is supported on the valve seat 34 which is provided with the diffuser 28, also imparting a displacement until the flange 29 abuts on the flanges 3 which is provided with each sector of the chimney 2 at the same time, the cooperation between the needle 37 and the valve seat 34 seals the chamber 52.
  • the air in the chamber 56 is compressed and, when the notch 62 of the shutter 41 passes in front of the lip 13, this air is expelled down inside of the container.
  • the pressure on the diffuser 28 is stopped, fluid passes from the container into the chamber 56.
  • the chamber 52 is sealed by the needle 37 in a positive manner, under the double action of elasticity, on the one hand, of the membrane 24 and, on the other hand, of the spring 43.
  • the expulsion under pressure of the accumulated liquid takes place simultaneously with a relative movement between the piston 20 and the diffuser 28-while remaining integral, one with respect to the other-, this movement being of small amplitude and opposite to the direction of support 57.
  • the housing 15 serves as a reservoir for the movement of the rod 41 in the low position.
  • Figure 4 shows a section where we can see the movement of the membrane 24 and the needle 37 (arrow 61) and the decline of the same needle (amplitude 60).
  • FIG. 5 represents another embodiment of the membrane to increase its surface and, implicitly, its flexibility.
