Definitions
- the invention relates to a device for the automatic filling of water in battery cells with a filler plug which can be inserted into the cell and which has a connecting piece for the water supply and a valve actuated by a float, the valve body of which is connected to the valve via a pivotably mounted lever Centrally arranged in the plug housing float is articulated.
- Such a device is the subject of DE-C 31 27 619.
- the movements of the float are transmitted via a reinforcement lever to a shaft with a prismatic cross-section, which actuates a valve body which is arranged essentially horizontally when it rotates and operates the valve body in the closed position when the filling level is reached.
- the water supplied runs through a central opening in the bottom of the plug housing into the battery cell and ensures sufficient lubrication of the float rod.
- the invention is based on the object of providing a further improved filling device for battery cells, which is composed of as few individual parts as possible and is therefore easy to assemble, at the same time ensuring by a simple measure that the with the Connections connected supply lines are usually always filled, thereby ensuring security against hydrogen explosions and the Prevent dreaded ignitions to several plugs connected in series.
- this object is achieved according to the invention in that a substantially vertical overflow wall is arranged between the valve with the hanging valve body and the connecting piece, the free upper edge of which is higher than the horizontal bore upper edge of the connecting piece, of which a U -shaped inlet channel leads to the overflow wall.
- the overflow wall which is very high compared to the previously known filling device, forms a partition, so that the water is always in the U-shaped inlet channel up to the upper edge of the bore of the connecting piece, which produces a siphon effect which effectively prevents the feared ignition of hydrogen explosions. Due to the hanging arrangement of the Ventil ⁇ body there is a lot of space upwards, so that the overflow wall can be pulled very far up.
- the vertical U-leg originating from the connecting piece is formed by a cylinder which is closed on its underside and from which a lateral connecting duct opens into a cylinder housing parallel to it, in the upper region of which the overflow wall is formed.
- the further water supply then takes place in such a way that an inlet channel leads laterally from the upper region of the cylinder housing into a valve cylinder parallel to the cylinder housing, in which the valve seat for the hanging valve body is formed.
- a further channel in the form of an upside-down U is connected to the U-shaped inlet channel.
- Inlet openings are worked into the bottom of the valve cylinder, which lead into the battery cell on the side next to the float. This has the advantage that the incoming water does not hit the float from above, but laterally into the bathtub. Series cell flows so that the float movements to close the valve are not affected.
- the downward-facing end of the valve body shaft is connected in an articulated manner to the central vibrating rod via a reinforcing lever which is pivotably mounted on a tilt support.
- the tilt support and the inlet openings are formed on an essentially circular base plate which is integrally connected to the cylinder housing via a hinge joint, which is designed as a one-piece injection molded inner housing with the valve cylinder and the cylinder receiving the inlet channel is.
- This injection molded housing can be easily manufactured and assembled in a single mold, the base plate being folded against the underside of the inner housing and thereby closing it at the bottom. Since the channels for the water supply are also injection molded with the inner housing, measures for subsequently closing the channels at openings from which mold cores have to be pulled out are unnecessary.
- the longer end of the reinforcement lever is connected in an articulated manner to an arm which projects horizontally from the float rod and from the free end of which a vertical rod protrudes upward, which carries an indicator disc which, when the valve is closed, passes through a window is visible in a cover in the plug housing.
- the float rod is hollow and engages with its upper end in a guide cylinder closed at the top, which is formed in the central cylinder housing and from the ceiling of which a guide pin protrudes downward, which engages in the upper end of the hollow float rod.
- the guide pin has a cross-shaped cross section such that vertical drain slots are formed on its long sides. The lower end of the float rod can be snapped into the float and has a side drain opening above it.
- the measures described ensure that the float rod is always guided smoothly and is largely protected from the effects of foreign particles on the one hand by the telescopic guide on the guide pin and on the other hand by the storage in the guide cylinder closed at the top. It is in fact never to be avoided that the rough operation of the battery cells at the respective place of use causes dirt and in particular oily particles to get into the cells, which in the case of previously known filling devices can lead to the float rod becoming stiff.
- a vertical connecting piece leading to the connecting piece engages in the cylinder receiving the inlet channel and is formed in one piece with the plug housing, from its horizontal top side, to which the cover is articulated, into the Battery cell insertable, radially resilient side walls protrude downwards.
- FIG. 1 shows a filling device according to the invention inserted into a battery cell during the filling process
- FIG. 2 shows a representation of the filling device corresponding to FIG. 1 with the valve closed
- FIG. 3 shows a side view of the filling device
- FIG. 4 shows a side view rotated by 90 ° with respect to FIG. 3,
- FIG. 5 shows a top view of the filling device with the lid open
- Figure 6 is an exploded view of the plug housing and Figure 7 is an exploded view of the injection molded inner housing with the elements mounted therein.
- FIGS. 1 and 2 show two battery cells 10 lying next to one another, in the upper opening 12 of which a filling device 14 designed according to the invention is inserted.
- Each filling device 14 consists of an outer, cylindrical plastic plug housing 16 (FIG. 6) and an inner housing 18 (FIG. 7) inserted therein, which is essentially produced in one piece as an injection molded part.
- FIG. 6 shows, a T-shaped connecting piece 24 is inserted into a side seat 20 of the plug housing 16 with the interposition of an O-ring 22.
- connection piece 26 and a connecting piece 28 projecting downwardly from the middle of the piece.
- FIG. 5 shows that the two connecting pieces 26 form an obtuse angle with one another, which facilitates the connection of hose lines.
- Radially resilient side walls 38 protrude from the top 30 of the plug housing 16 and are inserted with the interposition of an O-ring 40 with a snap fit into the opening 12 of the respective battery cell 10.
- the injection-molded inner housing 18 is inserted between the radially resilient side walls 38 of the stopper housing 16 with snap engagement.
- This has a cylinder housing 42 arranged vertically in the middle, on the left side wall in FIG. 7 of which a valve cylinder 44 parallel to it is integrally formed.
- a cylinder 46 which is also axially parallel, is formed on the cylinder housing 42, the underside of which is closed and the top of which is open, so that in the assembled state of the filling device 14 the downward-facing connecting piece 28 of the connecting piece 24 engages in this cylinder 46.
- a lateral connecting duct 48 leads from the connecting piece 28 and thus the cylinder 46 into the central cylinder housing 42, which is connected in its upper region to the valve cylinder 44 via a lateral overflow duct 50.
- a guide cylinder 52 is formed centrally in the cylinder housing 42 and is integrally formed on the connecting wall 56 between the cylinder housing 42 and the valve cylinder 44 via a web 54.
- the guide cylinder 52 is closed on its upper side by a ceiling 58, from which a vertical overflow wall 60 protrudes.
- the free edge of the overflow wall 60 is a distance higher than the horizontal upper edge of the bore of the two connecting pieces 26. According to FIG. 1, this forms a U-shaped inlet channel 94, which acts like a siphon and ensures that the connecting pieces 26 are always filled with water are filled.
- Figure 1 further shows that behind the overflow wall 60, the water flows through the overflow channel 50 under the valve body 62 of the open valve, which is lifted up from its valve seat 64 in the valve cylinder 44 due to the downward movement of the float 96 when the battery cell 10 is insufficiently filled.
- the supplied water flows down through inlet openings 66 to the side next to the float 96 into the battery cell 10.
- the inlet openings 66 are machined into an essentially circular base plate 68 which, according to FIG. 7, is formed in one piece with the cylinder housing 42 via a hinge joint 70.
- the base plate 68 is pivoted upwards from the position shown in FIG. 7 around the hinge joint 70 until it rests on the underside of the inner housing 18 and closes it off at the bottom.
- a tipping support 72 protrudes, on which a two-armed lever 74 is pivotally mounted.
- the shorter end of the lever 74 hinges in a recess in the shaft 76 of the hanging valve body 62, while the free end of the longer arm of the lever 74 hinges in a recess 78 of an arm 80 which projects horizontally from the float rod 82.
- the Length ratio of the two arms of the lever 74 is 1: 2.4 in the exemplary embodiment, so that the float force is converted into a correspondingly greater closing force of the valve body 62.
- a vertical rod 84 extends upward, which carries an indicator disc 86, which is visible through the window 36 in the cover 34 of the plug housing 16 when the valve is closed. This state can be seen in Figure 2.
- a guide pin 88 protrudes downward from the inside of the ceiling 58 of the guide cylinder 52 and engages in the upper end of the hollow float rod 82.
- the guide pin 88 has a cross-shaped cross section, so that four vertical drain slots 90 are formed on its longitudinal sides.
- the lower end of the float rod 82 is snap-fitted into the float 96 and has openings 92 above this side drain.
- the explained, hollow design of the float rod 82 and its telescopic guidance on the guide pin 88 has the advantage that there is always sufficient water lubrication and self-cleaning of often inevitable floating particles and dirt particles.
- the constantly fluctuating water level causes the float 96 to move continuously, so that a pumping movement takes place between the guide pin 88 and the hollow float rod 82, which is always filled with distillate due to the capillary action, which on the one hand brings about lubrication and on the other hand ensures that that particles which have penetrated into the hollow float rod 82 are pressed down and are repelled via the outlet openings 92.
