- Figures 1 and 2 represent two embodiments of the device according to the invention, the same references designate the same elements or means there, whatever the figure on which they appear and whatever the shape of representation of these means.
- the device an embodiment of which is illustrated in FIG. 1, makes it possible to empty a container of viscous fluid like oil contained in the engine block of a motor vehicle or the like, in a environment in which there is a pressurized atmosphere and a gravitational force, as in the ambient air reigning on Earth.
- This device comprises a container 1 with a wall 1 defining a main volume 2 able to contain viscous fluid, this container being shaped to be able to be placed in the ambient medium so that the main volume has a high part 3 and a low part 4.
- a partition wall 5 located in the main volume 2 delimits, in this main volume, two first and second secondary volumes 6, 7, the first secondary volume 6 including at least a portion 9 of the upper part 3 of the main volume 2.
- An orifice 8 is made in the partition wall 5 to put the two first and second secondary volumes 6, 7 into communication, this orifice opening into the second secondary volume 7 in the portion 9 defined above of the upper part 3 of the volume main.
- the device further comprises a pump 10 comprising a suction inlet 11 and a discharge outlet 12.
- the pump is mounted in cooperation with the container 1, and more particularly with its wall 19 as will be described below, so that its suction inlet 11 is located in the first secondary volume 6 and that its discharge outlet 12 opens to the outside 13 of the container 1.
- the device also comprises a tube 14 comprising an inlet mouth 15 and an outlet mouth 16, and means 17 for mounting this tube 14 in association with the container 1 so that its outlet mouth 16 is located in the second volume secondary 7 and that its inlet mouth 15 is located outside 13 of the container 1, the end 18 of the tube 14 comprising the inlet mouth 15 being shaped to be able to immerse in the container to be drained.
- the end 1 8 of the tubing 1 4 comprising the inlet mouth 15 is flexible so as to be able to easily plunge into the bottom of the greatest possible number of containers of any shape whatsoever, and the means 17 defined above are advantageously constituted by a sealed passage 24 produced in the wall 19 of container 1.
- This sealed passage is advantageously coupled with a removable plug to allow the container 1 to be emptied when it is relatively full and thus be able to reuse the device for another emptying.
- the device is arranged so that the secondary volume 7 defined above is divided into two first and second auxiliary volumes 21, 22, these two auxiliary volumes communicating with each other by a constriction 23 preferably formed between the wall 19 of the container and the separation wall 5, this constriction constituting a significant pressure drop for the viscous fluid.
- the first auxiliary volume 21 is located in the upper part 3 of the main volume 2 and the orifice 8 opens into this first auxiliary volume 21.
- the device comprises a pump 10.
- this pump 10 comprises a cylindrical body 30, one first end 33 of which is tightly secured to the wall 19 of the container 1 and the other of which end 34 opens into the first secondary volume 6; a piston 35 slidably mounted in the cylindrical body 30; a rod 36 for controlling the translation of the piston; and a valve 38 mounted in cooperation with the piston 35, this valve being “on” when the control rod 36 enters in translation in the cylindrical body 30 in the direction indicated by the arrow 61 in the figure, and “closed” when the control rod exits the cylindrical body by the translation indicated by the arrow 62 in this same figure.
- the control rod 36 is further produced so that it passes without sealing through an opening 31 made in the wall 19 of the container and that one of its ends 37 is constantly located outside 13 of the container 1.
- the partition wall 5 is advantageously constituted by a cylindrical sleeve 40 of a length greater than that of the cylindrical body 30, this sleeve being mounted integral, at one of its ends 41, 42, with the wall 19 of the container 1 so that it is substantially concentric with the cylindrical body 30 by delimiting, between its internal face 45 and the external face 46 of the cylindrical body, a first annular space 43, and by a plug 44 for sealingly closing the other end 42 of this sleeve 40.
- the first auxiliary volume 21 forms around the sleeve 40 a second annular cylindrical space 50 of the same thickness as the constriction defined above, this second annular space 50 being in fact, as visible in the figure, d 'a length less than the length of the sleeve 40.
- the device For safety and to obtain correct operation whatever the volume of the fluid to be drained, the device comprises a valve 55 mounted in cooperation with the orifice 8 so that this valve is "passing" in the direction of the second secondary volume 7 towards the first secondary volume 6.
- the valve 55 is constituted by an elastic ring 56 mounted in the first annular space 43 and by a sealing stud 57 mounted in cooperation with the ring 56 so that it is capable of closing the orifice 8 under the elastic force exerted by this ring, and to move away from this orifice when the ambient atmosphere is sucked in by the pump 10 to pass, as will be explained below, from the second secondary volume 7 to the first secondary volume 6.
- the device has a structure like that described above, it is advantageous that at least the container 1, the partition wall 5, the tube 14 and the cylindrical body 30 are made of plastic, in particular by molding, which can only help to considerably reduce the manufacturing price of this device according to the invention.
- this device is used in an environment where there is a pressurized atmosphere and a gravitational force, for example on Earth, that the container 1 is initially completely empty of any liquid and that one proposes to use it to drain the oil contained in the not shown engine block of a motor vehicle or the like.
- the end 18 of the pipe 14 is introduced into the engine block so that its inlet mouth 15 plunges into the oil, preferably to the bottom of the engine block.
- control rod 36 is then moved back and forth according to the arrows 61 and 62 so that the piston 35 traverses the interior 32 of the cylindrical body 30.
- the valve 38 is on and the piston 35 sinks without appreciable displacement of the atmosphere which is in the cylindrical body.
- the valve 38 closes and creates a vacuum between the piston 35 and the suction inlet 11.
- the atmosphere which is in the cylindrical body 30 above the piston is evacuated by the discharge outlet 12 constituted, in the illustrated embodiment, by the opening 31.
- the atmosphere which is in the second volume secondary 7 is sucked to enter the first secondary volume 6 by opening the valve 55.
- the depression which occurs in the second secondary volume 7 makes it possible to suck up the oil contained in the engine block due to the pressure difference which product between the atmosphere outside the container 1 and which acts on the oil to be drained and that which reigns in the second secondary volume 7.
- the discharge outlet 12 of the pump is coincident with the opening 31. Also, so that the atmosphere which is extracted from the container when the control rod 36 is pulled along the arrow 62, can exit outside the container 13, the section of the opening 31 is made so that it is greater than the cross section of the control rod 36 so that there is sufficient space between this rod control and the edge of the opening, as shown in the figure.
- FIG. 2 represents a second embodiment of a device according to the invention, the main characteristics of which are defined above, in particular with regard to the figure 1.
- the device comprises, as in the first embodiment, a pump 10 mounted in cooperation with the container 1 of which only a part has been shown, so that its suction inlet 11 is located in the first secondary volume 6 and that its delivery outlet 12 opens to the outside 13 of the container.
- the pump 10 comprises a pump body constituted by the partition wall 5 defined above in the description of the first embodiment, a piston 70 mounted to slide in the pump body 5 to delimit, in the first secondary volume 6, two first 71 and second 72 chambers, the orifice 8 opening into the first chamber 71 via the valve 55, as in the first embodiment according to FIG. 1.
- the piston 70 is shaped as a second valve so that the latter valve is “on” when the piston 70 moves in the pump body when the volume of the first chamber 71 decreases and that of the second chamber 72 increases. , and “closing" when this piston moves so that the volume of the first chamber increases and that of the first chamber decreases.
- the pump 10 also comprises a control rod 73 for the translation of the piston 70 in the pump body 5, one end 74 of this control rod being located outside 13 of the container 1, passing through a sliding sealed passage 75 la wall 76 of the container 1 separating the first chamber 71 and the exterior 13, means 77 for communicating the second chamber 72 with the exterior 13 of the container 1, and valve means 78 having a "passing" direction only in the direction of the second chamber 72 towards the outside 13 of the container.
- the sliding sealed passage 75 is represented diagrammatically by a breakthrough surrounded by a sealing bellows connecting the edge of this breakthrough and the piston 70, but it is quite obvious that this sealed passage can be constituted by other means, for example by an O-ring seal or the like.
- the means 77 for putting the second chamber 72 into communication with the outside 1 3 of the container are constituted by a pipe 79 passing through the piston 70 and at least partially the control rod 73 so that its two ends 80, 81 constantly open respectively into the second chamber 72 and outside 13 of the container.
- the valve means 78 are mounted in cooperation with this pipe 79, for example at its end 81.
- Valve means 78 like those defined above are well known in themselves and will not be described specifically here, for the sole purpose of simplifying the present description.
- the piston 70 shaped as a second valve comprises for example a piston body 82 of an outer section smaller than the section of the first secondary volume 6, a circular groove 83 produced in this piston body , an annular seal 84 disposed in the circular groove, the outer annular section of the seal 84 being equal to the inner section of the first secondary volume 6 and its inner annular section being equal to the bottom section 85 of the groove 83, the width of the groove being greater than the thickness of the annular seal, and means 86 for bringing the circular groove 83 into communication with the second chamber 72.
- the piston 70 which reduces the volume of the second chamber 72.
- the piston 70 being shaped as a "shutter" valve when it moves in the direction of reducing the volume of the second chamber, it makes it possible to compress the air located in this chamber 72 and to expel it, via the pipe 79 and the valve 78, towards the outside 13 of the container 1 .
