Definitions
- the invention relates to a funnel with level indicator for the safe filling of liquids in containers, consisting of a cross-passing through the funnel neck bearing for a along the funnel axis measuring rod, which carries a movable in the funnel neck, piston-like float as a buoyancy element below the bearing, in the wall of the funnel nozzle there are several passage slots for the liquid to be filled and the movement of the measuring rod is limited in both directions.
- the bearing passing through the funnel neck consists of a disc having a central bore, which is located relatively in the lower region of the funnel neck.
- the measuring rod guided therein has the float underneath the disc, the buoyancy of which can be recognized by the liquid which is filled in by the movement of the measuring rod.
- This carries in the upper area a plate-like display device which, when reaching a certain height against the wall of the funnel cup, signals that the container is sufficiently filled.
- the invention is based on this prior art according to DE-GM 75 29 052 and sets itself the task of improving the level indicator device in such a way that it is not only dependent on the observation of the measuring rod, but also further indications for the level of the Obtains opaque container and that the filling of opaque containers in particular, especially with fuel, is facilitated in general.
- the final filling level of the liquid in the container can be seen on the one hand from the height position of the measuring rod, and attention is also drawn to this by the accumulation of the liquid in the funnel cup.
- the pent-up liquid can then easily get into the container if the funnel is lifted slightly because the float does not participate in this lifting movement.
- the funnel according to the invention can be used wherever liquid is filled into primarily opaque containers.
- the subject of the invention is the subject of the invention in the filling of fuels in motor-driven equipment, especially in lawn mowers, with the
- ERSATZBLAH (REGEL26) Internal combustion engines are driven. There is the additional problem that the overflowing of the fuels to be filled must be prevented especially in order to avoid the ignition of the liquid on the hot work equipment.
- sub-claim 2 it is achieved that due to the dome-shaped design of the float and the sieve plate, the centering and sealing of the float in its upper position is improved, whereby the closing of the openings in the sieve plate takes place suddenly and instantaneously under the buoyancy of the float the liquid builds up above the sieve plate. There can therefore be no doubt in the observation that the container is properly filled.
- sub-claim 3 gives an additional indication for the detection of the approaching end of the filling process.
- a circumferential gap provided between the float and the funnel connection has the effect of a throttle in connection with the position of the passage slots. If the float approaches the upper end position due to the buoyancy of the liquid, the flow rate of the liquid through the sieve plate will decrease. This can be seen from the slower drop in the liquid level in the funnel cup. The operator is therefore warned that the filling process will soon be finished and will accordingly
- REPLACEMENT BLA ⁇ (RULE 26) be reluctant to refill the funnel goblet.
- subclaim 5 fulfill the condition that the float in its lower end position hits a stop which is arranged such that the measuring rod (7) still protrudes a certain area beyond the sieve plate.
- the easier assembly of the float, the measuring rod and the sieve plate is achieved. It has proven to be expedient to first pass the measuring rod of the float through the fitting bore of the sieve plate outside the funnel before the sieve plate together with the float arrangement is brought into its working position.
- the features of the invention ensure that the filling of the liquid into the container or the consumption of the liquid in the container does not pose any problems of overpressure or underpressure.
- ERS ⁇ ZBL ⁇ (RULE 26) 1 a vertical section through a funnel
- FIGS. 6 a vertical section through a funnel as an alternative to FIGS. 1 and
- Fig. 7 a vertical section through a
- the funnel (1) consists of the funnel cup (14) and the funnel neck (4) which adjoins at the bottom.
- a sieve plate (2) passes through the funnel neck (4), through the holes (3) of which the liquid filled into the funnel cup (14) can flow downwards.
- a measuring rod (7) of a float (6) projects upwards.
- the position of the float (6) shown in FIG. 1 is the upper end position which arises when an opaque container into which liquid is to be filled by means of the funnel (1) is filled. The buoyancy of the liquid pushes the float (6) up until it reaches the underside of the sieve plate (2).
- the sieve plate (2) is dome-shaped and arched upwards.
- the upper face of the float (6) is designed accordingly.
- the float (6) is also designed as a hollow body which is open on its underside. The buoyancy of the filled liquid in connection with this dome-shaped design of the sieve plate (2) and float (6) leads to a better centered contact of the float (6) on the underside of the sieve plate (2) when the filling process has progressed so far is that the float (6) rests on the sieve plate (2). With this arrangement, a better sealing of the sieve plate with respect to the float (6) is achieved, so that the liquid still poured into the funnel cup accumulates above the sieve plate (2).
- An exchange of the sieve plate (2) with the float (6) and the measuring rod (7) is possible at any time, for example to clean the system or to use another sieve plate (2) with differently designed holes (3).
- the individual passage slot (5) has a circular extension (15) approximately in the central area. As shown in FIG. 3, this should be located approximately above the float (6) when it is in its lower position. The impinging liquid then exerts a reduced flow pressure on the float (6) because, owing to the enlargement of the slot, it can flow off more quickly.
- This extension (15) can also be used to hang the funnel (1) on a hook, bolt or the like. The position of the extension (15) must therefore be chosen so that the float (6) cannot cover the extension (15).
- an upright comparison rod (16) is located on the sieve plate (2) and extends parallel to the funnel axis. Your upper end (17) is slightly lower than the upper end (18) of the measuring rod (7) when the float (7) is in its uppermost position. This provides an additional indication for the determination that the filling process has been completed.
- FIG. 3 also shows the arrangement of upright ribs (27) on the outer surface of the funnel cup (14), which are designed to form ventilation gaps between them through which the air which may be compressed when the liquid is filled into the container can escape.
- These ribs (27) sit on the edge of the container filling opening and therefore allow the compressed air to escape from the container.
- the connection of the funnel nozzle (4) to a screw sleeve (19) is shown, which serves to screw the funnel nozzle (4) onto a tank nozzle (23).
- the screw sleeve (19) accordingly has an internal thread (24) adapted to the tank neck (23).
- the funnel (1) or the funnel nozzle (4) can be firmly anchored to the container (25) and, accordingly, both hands used to hold the refill container.
- the screw sleeve (19) can be injected with the funnel nozzle (4) as a one-piece plastic member. However, it is also possible to design the screw sleeve (19) in the manner of a union nut and to allow it to act against a collar-like attachment (not shown) of the funnel neck.
- the screw sleeve (19) or the funnel connector (4) has a socket (20) for pushing on a transparent cap (21).
- the transparent cap (21) is secured in the mount (20) by a bayonet lock (26), but a thread lock can also be provided in its place.
- the funnel (1) can be present in the embodiment of FIG. 4, but this is by no means necessary.
- the funnel cup (14) can be used as an exchange element against the clear cap (21). If you want to fill the container (25), remove the clear cap (21) and insert the funnel cup (14) into the holder (20). After the filling process has been completed, the funnel cup (14) can be removed again and replaced by the transparent cap (21).
- the chamfer (20) is designed as an external thread, onto which both the funnel cup (14) or the transparent cap can be screwed.
- the ventilation of the container (25) should be ensured when filling or when consuming the liquid.
- the wall of the screw sleeve (19) has a vent hole (28) through which the air compressed during the filling process can escape from the container (25).
- FIGS. 6 and 7 show how alternatives to the examples in FIGS. 1 to 5 can be developed.
- the funnel (1) has an external thread (34) on its connecting piece (35), so that the funnel (1) can be screwed into an internal thread (39) of the funnel piece (4) instead of the clear cap (21).
- the sieve plate (2) is supported on a step (36) of the funnel part (22) and can therefore be removed upwards.
- the transparent cap (21) according to FIG. 7 is dimensioned relatively short. It also has an external thread (34) for screwing into the screw sleeve (19).
- the transparent cap (21) clamps an additional sieve disc (30) in which the measuring rod (7) is guided, even when the funnel (1) is unscrewed from the funnel nozzle (4).
- This also has the advantage that an indication of the empty position of the container (25) can be obtained by dimensioning the lengths of the funnel nozzle (4) and the measuring rod (7). If the funnel nozzle (4) abuts the bottom of the container (25) or a raised bottom surface of the container (25) and the float (6) has reached its lowest position when the container (25) is emptied, the upper edge of the measuring rod results a measure of the empty position of the container (25). In the present case of FIG. 7, the measuring rod (7) protrudes only slightly beyond the additional perforated plate (30) and signals the emptying of the container (25). FIG. 7 also shows that the float (6) has a smaller outside diameter than the bore of the funnel nozzle (4).
- a sealing washer (37) with at least one ventilation hole (38) can also be provided. This means that air can get into the tank from the outside through the threads of the internal thread (24) if a negative pressure occurs in the tank due to fuel consumption.
- the transparent cap (21) of FIG. 7 is considerably shorter than that of FIG. 4, it does not interfere with the position of the measuring rod (7) when the container is full.
- the measuring rod (7) rather abuts the upper end of the cap and is pressed into the container.
