Description

 Multipurpose plunger, pneumatic or hydraulic pressure, transformable into transfer pump.

 The present invention relates to disgorging instruments, for blowing or injecting, in an alternating or unilateral, progressive and controlled manner, air 6u liquids in blocked pipes.

 Its shape and design allows it to transform into a transfer pump, it is versatile.

 In the currently known process, applied to disgorging of sanitary appliances, the individual most often uses chemicals.

 The professional dismantles the siphons or generally uses a flexible 1/2 spherical rubber suction cup surmounted by a solid wood operating handle.

 This suction cup is immersed in waste water that has not been drained and is placed at the bottom of the blocked device, either on the drain or in the toilet bowl.

 The operator by a compression movement, suction on the discharge orifice, tries to remove the obstructing plug, generally blocked in the siphon.

 The disadvantage of this system, as well as any other based on the principle of the piston, lies essentially in the fact that the obstructing plug is simply moved alternately. It is not gradually and systematically pushed towards the drop column.

 During compression, the suction cup only pushes back the volume of air contained in its 1/2 sphere, during suction the eolonne of water contained in the siphon returns to its original place and the obstructing plug returns to its starting point.

 There are the same drawbacks with plungers or the like.

 To arrive at the opening, the operator is forced to remove the suction cup from the water to renew the air contained in the 1/2 sphere.

 Its compressive force is limited to the air capacity occupying the 1/2 sphere.

 He works in pneumatics, the suction cup not being able to retain water when it comes out of the liquid, it is not possible for him to inject additional water and to work in hydraulics.

 The shape of all these plungers, either with suction cup or piston is not designed to adapt in a versatile and functional way to the various shapes of existing sanitary fixtures in the world.

 Almost all are studied to unblock the sanitary appliances, very little for the disgorgement of the W.C.

 even with adaptation additives, they are not effective, this being due to the diversity of forms.

 The drain according to the invention aims to remedy these drawbacks.

 It consists of an iconic rubber pocket, associated with an operating handle.

 Its shape of 2 inverted cones distinguishes it from 1/2 spherical spouts.

 Its air capacity, much higher, generates one. higher pressure directed at the injection.

 Its conical tip 6, allows it to enter all siphons of W.C.

 The more restricted cylinder 8 allows water retention and work in hydraulics.

 The contact lips 9 are designed to adapt specially to the overflows of sanitary appliances.

 The innovation is even more marked by the fact that with this single device The operator sees the range of his possibilities widening.

 The versatility of this device will solve all the problems posed by disgorgement, in very specific cases.

 In fact, this drainer, apart from its functional form adapted to various sanitary appliances, will be able to operate in a different way, depending on whether the operator will need, or, in the first version, IVF. 1. of a nozzle for working in alternating suction pressure, that is, in second version, fig. 2 and 3.in unilateral injection of compressed air.

or, by unilateral hydraulic injection.

 This device, easy to use, always ready to use, requires no maintenance.

 The present invention will be better understood with the aid of the descriptions which follow, with reference to the appended diagrams and diagrams, representing by way of nonlimiting example, a form of apparatus, used, either as an outlet or as an explosion-proof transfer pump .

 According to a first variant, plate 1/3, Figure 1.

shows a sectional view of the drain at rest in its simplest application.

 Structure 2. Grab handle.

 Function. Allows the operator to hold the device firmly, even with wet hands.

 Structure 3. Solid wood operating handle.

 Function. It is used by the operator to activate the unblocker, by an alternating movement of compression, suction.

 Structure 4. Pushing base, provided with a radial hole, associated with the operating handle.

 Function. This solid, semi-rigid base, under the crushing effect given by the operator, will gradually penetrate the cone 6. and compress the volume of air.

 Structure 5. Deformable bellows of movement, necessary for compression and aspiration.

 Function. They reduce the thrust resistance and allow penetration and guiding of the base 4.

in the cone 6.

 Structure 6. Conical body, slightly deformable by internal pressure.

 Function. The conical body, specially designed to penetrate the interior of the WC siphons is externally graduated by ribs, delimiting and indicating the m of penetration, suitable for each model of bowl.

 These ribs serve as anchors, they prevent the cone from dislodging during the high compression operation.

 Under pressure; the cone 6, swells slightly and its outer part is pressed into the interior of the siphon, it follows its shape and creates a seal.

 Structure 7. Ribs indicating 0 and anchoring.

 Their function is described in the previous paragraph.

 Structure 8. The cone 6 is extended by a cylindrical portion with bellows 8.

 Its 1st function is to orient and press the lips 9. at the bottom of the appliance to make the plunger waterproof when the shape of the sanitary appliance or the location of the drain does not allow the plunger to present itself perpendicularly.

 Its 2nd function. This cylinder is characterized by the fact that being of a B more restricted than the maximum width located at 5. The cylinder allows the retention of water sucked in when the drainer works under hydraulic pressure and that the lips 9 have lost contact with the bottom of the device.

 Structure 9. The sealing contact lips, characterized by the suction cup-shaped underside.

 Their first function is to adhere to the overflows of sanitary appliances to prevent the compressive force from escaping when air is injected into the siphon.

 In the case of increased resistance of the obstructing plug they act as an exhaust valve and let the air contained in the drainer go.

 At this precise moment, the unblocker works in suction.

 It moves by suction the same volume of water residing in the siphon, until the pocket is filled with it.

 Without moving the drain, the operator pushes this volume of water back into the siphon, the drain becomes hydraulic.

 This operation, suction, delivery continues until the obstructing plug is removed.

 If the operator wants to work only in pneumatics after each air compression, he removes the drain from the water to prevent it from filling up.

 A second application variant shown on board 2/3. Figure 2 and 3 is characterized in that the drain is equipped with a hollow handle associated with an air inlet check valve.

The unblocker then works under renewed unilateral pressure, pneumatic if the air intake 1 is in the open air.
HYDRAULIC if the air intake 1 is replaced by a rubber holder fitting 14 connected to a flexible hose immersed in a liquid.

 Description, structure, function, plate 2/3.

 FIG. 2 is a cross-sectional view of the drainer, when the device after loosening on the handle has finished its air suction phase, by the strainer 1. the valve 2. the hollow handle 3.

 Structure 1. Removable strainer.

 Function. It lets air into the body of the drain.

 It protects the mechanism of valve 2.

 It prevents the operator by maneuvering the device from obstructing the air intake orifice.

 Structure 2. Non-return check valve.

 Function. It opens and lets the necessary air penetrate into the drainer during the suction phase, when after compression the bellows 5 resume their initial shapes.

 It closes automatically when the suction phase is finished.

 Structure 3. Hollow operating handle.

 Function. Associated with valve 2 and base 4.

it allows the free passage of air to renew the volume of the drain.

 He participates in the operation of the device.

 Structure h. Thrust base, pierced.

 Function. It is characterized by the fact that it is pierced, contrary to what is described in FIG. 1.

 The structures and functions of 5 - 6 - 7 - 8 - 9 are the same as those described for Plate 1/3. fig. 1.

Figure 3 is a sectional view of the drain, when the device is in the compression, eXpiration, injection phase
Under the vertical compression effect that the operator gives on the operating handle 3 the valve 2 closes. The base 4 enters the body of the cone 6.

the bellows 5 are deformed and tightened.

 The trapped air compressed in the body of the cone 6.

can no longer be evacuated only towards the siphon or the blocked pipe.

 He pushes the obstructing plug there, unilaterally.

 This operation is repetitive without moving the drain.

 Transfer pump. 1st variant.

 This device is not only limited to disgorging the pipes, but can be used as a transfer pump.

 It suffices to screw in place of the strainer 1 on the check valve 2. a. rubber holder fitting 14 extended by a flexible hose immersed in a container containing the liquid to be transferred.

 On the other hand the plunger will be placed in another container with a flat and smooth bottom, the lips 9 in contact with the bottom, act as a valve.

 Under the vertical pressure of the handle 3. the liquid is forced back into the container, it passes under the lips 9.

When the pressure is released on the handle 3, the lips 9 press against the bottom of the container and prevent the air intake
The bellows 5, taking their place, renew the volume of the body 6, which is sucked in by the handle 3 the valve 2, opens. The flexible hose draws the liquid into the container to be transferred.

 This repeated pumping operation allows the transfer of liquids.

 2nd variant. Plate 3/3. Figure 4 and 5.

 When the operator needs to transfer liquids to different levels and the transfer pump must operate in the open air.

 A complementary part, FIG. 5, will be fitted inside the cylinder 8, by simple interlocking.

 Structure Fig. 5. Adapter for transfer pump to the open air.

 Function 10. Contact plate to receive the lips 9.

End piece 11, with sealing rib, with anchoring in the inner cylinder 8. Nipple 12, threaded for screwing the check valve 13. End piece 14, rubber holder receiving a flexible delivery pipe.

 Regarding the suction, the device remains equipped with the same parts set out in the previous chapter, i.e., 114 - 2 - 3.

 The invention will be clearly understood using the board 3/3 in FIG. 4, which shows by way of example, a transfer pump transferring a 200 L petrol drum into a 20 L jerry can.

or directly in a car tank.

 The handling of this lightweight device is easy to use.

 After having introduced the suction tube into the barrel to be drawn off, the delivery pipe into the tank to be filled, the operator will carry out the pumping movement by taking with both hands, the valve 2 upstream, to on the other hand the valve 13 downstream.

 By compressing and releasing successively the transfer pump as in Figure 3, the liquid will be transferred from one container to another.

 To perform the opposite operation, it is enough to alternate the pipes.

 The undisputed advantages of this invention are that, this entirely mechanical pump, devoid of an electric motor, is explosion-proof, for the transfer of hydrocarbons.

 For example, it can transfer, either, air (inflation pump) fresh or salt water, fuel oil, petrol and derivatives, all kinds of uncharged fluids, gaseous or liquid , without these materials being in contact with the atmosphere during their transfer.

 So no Persian matter, no risk of poisoning or risk of explosion.

 If the device is definitively assigned to this use, this assembly will be preserved.

 In the case where the user wants to reuse this pump as a drain cleaner, it suffices to remove the part shown in FIG. 5, without having to dismantle the additive parts 13 - 14.

 The device is ready to work as a drain cleaner.

 It is obvious that according to the fluid to be transferred, the material of the pump body 6 will be made of suitable material.

 This versatile device, instantly transformable, can be used either as a drain cleaner or as a transfer pump.

 It finds its application in many fields such as building, housing, industry, automobile> marine, etc ...
