1,194,215. Topping-up accumulators. ROBERT BOSCH G.m.b.H. 1 Sept., 1967 [6 Sept., 1966], No. 40061/67. Heading H1B. A storage battery comprises a housing having a cover, at least one tubular vent extending through the cover, and at least one fluid inlet aperture in the cover associated with each cell and communicating with a common fluid reservoir, the exit of each aperture within the housing being at a higher level than the lower end of the, or each, vent. In a particular embodiment, Fig. 1, a single cell of a 6-cell accumulator is enclosed by container 10 and cover 11, the cover being shaped into a filling trough 16 extending over all the cells and having an inlet 17 and a vent 18 to each cell, each vent being out 14 mm. wide to accommodate a device for measuring the S.G. of the electrolyte. The cell may be topped up with distilled water until the electrolyte level reaches the bottom of vent tube 18. The filling trough is itself filled via passage 20 and the trough and passage are covered by a second cover 21 of polypropylene. The cover is hinged at 26 so that in the position shown the projecting piece serves as an extension of the passage 20 but can also be turned over and inwards to close the entrance to passage 20. The cell inlets 17 may be slots of up to 3 mm. width or round holes of up to 5 mm. in diameter. |
