Definitions
- the present invention relates to a device for dispensing a substantially constant pressure fluid, more particularly a gas.
- Document FR 2 709 825 is also known which proposes a device for injecting a fluid intermittently.
- This device comprises a lower plate, an upper plate and a bellows hermetically arranged between these two plates.
- This assembly forms a flexible container whose outlet orifice is arranged in the upper plate.
- This container is pressurized by means of a spring which presses the upper plate towards the lower plate.
- this device is designed so that the pressure decreases regularly and substantially with the lengthening of the spring as the container empties.
- Document FR 2 895 885 which teaches a fluid dispensing apparatus, is also known.
- This device includes:
- the present invention thus relates to a device for automatically dispensing a fluid, which device has significantly improved performance as to the constancy of the pressure, while having a great mechanical simplicity.
- a device for dispensing a fluid comprises:
- this device comprises a return means which tends to press these two plates against each other.
- the hinge means comprises a loop which connects a first and a second opening respectively formed in the first and in the second plate.
- the return means is directly articulated on the two plates.
- the device comprises:
- a second connecting element secured at its first end to the second end of the first connecting element and secured at its second end to the second plate.
- This structure is intended to further reduce the pressure variations between the full container state and the empty container state.
- the return means is arranged between an anchor point on the second connecting element and an attachment point on the second plate.
- the biasing means is arranged between an anchor point on the second connecting element and an attachment point on the first connecting element.
- the device comprises several anchor points.
- the device has several attachment points.
- one of the connecting elements is a connecting rod.
- the flexible container is a pocket.
- the pocket has an orifice on which fits a micro-leak.
- the invention finds an advantageous application in the stimulation of plants.
- FIG. 1 a flexible container, more particularly
- FIG. 2 a first embodiment of the device according to the invention, more particularly
- FIG. 2a this empty container
- FIG. 3 a second embodiment of the device according to the invention, more particularly
- FIG. 3a this empty container
- FIG. 4 a third embodiment of the device according to the invention, more particularly
- a hollow container incorporated in the device of the invention takes the form of a flexible bag S provided with an outlet orifice S1 itself provided with a micro-leak S2.
- a flexible bag S provided with an outlet orifice S1 itself provided with a micro-leak S2.
- It is made by welding two sheets on their respective peripheries. This is for example a medical bag, an industrial bag or a food pocket. This pocket is shown empty in Figure 1a and full in Figure 1b.
- FIG. 2 a first embodiment of the device, the most rudimentary, is shown.
- This device comprises a first plate P1 or lower plate, a second plate P2 or upper plate, the pocket S described above, and a return means R, a spring in this case.
- This return means R tends to press these two plates P1, P2 against each other.
- the pocket S is disposed between the two plates P1, P2 which each comprise a passage for the outlet orifice S.
- Each plate P1, P2 has on one edge (the left edge in the figure) a first opening 01 into which is introduced a first loop B1, this to achieve a joint between the two plates P1, P2.
- the loop B1 is in wire, string or cable.
- the first opening 01 is located to the left of the outlet port S1.
- each plate also has a second opening 02 into which a second loop B2 is introduced.
- the upper plate P2 is extended by an appendage E (left in the figure), appendix on which is fixed an arm L inclined upwards.
- the lower plate P1 has on its rear edge a fixing point F.
- the return means R is arranged between the free end of the arm L and the fixing point F. It presses the second plate P2 in the direction of the first plate P1.
- the device always includes the first plate P1, the second plate P2, the pocket S and the return means R.
- the means of articulation of the two plates is also identical, although it can be replaced by a hinge or a pivot type mechanism.
- a first connecting element L1 sees its first end hinged to a first attachment point H1 on the first plate P1 on the opposite side to that of the openings 01, 02.
- a second connecting element L2 sees its first end hinged to the second end of the first connecting element L1.
- the second end of the second connecting element L2 is articulated to a second attachment point
- This second connecting element L2 is here as a triangle whose first vertex is articulated to the first connecting element L1 and whose second vertex is articulated on the second attachment point H2.
- the side of this triangle between its second and third vertex is crenellated to define three anchor points A, A2, A3.
- the first connecting element is here as a rod which is rigid. It could also be flexible, for example executed from a string, a cable or a string.
- the return means is arranged between an attachment point T on the second plate P2 and one of the anchoring points, the second one A2, in this case again, this biasing means tends to press the two pans P1, P2 one against the other.
- anchor points should not be considered as a limitation of the invention but rather as a means of adjusting the pressure applied to the pocket S. It could similarly provide several points of fixing on the second plate P2. Indeed, the distance between the fixing point and the anchoring point in conjunction with the sizing of the return means determines its performance of the device as to the variations of the pressure applied.
- the basic structure is taken, namely the first plate P1, the second plate P2, the pocket S, the return means R, and the means of articulation of the two plates P1, P2.
- the first connecting element M1 always sees its first end articulated to a first attachment point X1 on the first plate P1 on the opposite side to that of the loops B1, B2.
- the second connecting element M2 still sees its first end hinged to the second end of the first connecting element M1.
- the second end of the second connecting element M2 is again articulated to a second attachment point X2 which appears on the second plate P2 near its edge which is opposite to the one on which the loops 81, B2 appear.
- Each connecting element M1, M2 is in the form of an arch.
- the return means R is now arranged between an anchor point Y on the second connecting element M2 and an attachment point Z on the first connecting element M1.
- the anchoring points Y and fixing Z are each arranged at the top of the corresponding arches.
