摘要:
The gas release valve to be mounted in an access port of a battery cell comprises a housing (26) the upper side of which is closed by a lid (14) whereas the lower side has an opening (42) leading into the battery cell, said opening (42) being in communication, via degassing passageways closed by means of an elastic sealing element (38), with at least one vent (46) provided in the lid (14). The elastic sealing element (38) is a preloaded non-return element the inner surface of which is urged, into sealing contact with a seat (36) provided in said housing (26), by it s own elasticity and, in addition, by an increasing outer pressure acting through said vent (46) against the outer surface of said sealing element (38).
摘要:
Conductive element in a lead acid battery made up of a series of lead or lead alloy wires held in a support structure comprising a lower bar used to position lower ends of said wires, the upper ends of which are bunched together forming a bundle. Lead acid battery electrode made up of least one wire, wherein the wire has a core being covered by a coating of lead or lead alloy and embedded in a lead dioxide mass, the core being at least partially made of a highly conductive or semi-conductive non-lead material, the core being centered in a textile gaunlet. Conductive element in a lead acid battery made up of at least one lead or lead alloy tube containing a flowing cooling medium.

The system for opening and/or closing an inlet valve (10) and/or an outlet valve (30) of a liquid container (24), particularly for water toilets, water tanks or the like, comprises an inlet tube (16) with an inlet valve (10) in the upper portion of the container (24) and an outlet tube (20) with an outlet valve (30) in the bottom portion (25) of the container (24), both valves (10, 30) being provided with a valve body. It is characterized by the use of a bistabile inlet valve (10) having a lag-free opening and closing characteristic without any intermediate opening position of the valve body (14; 38,46), the closing stroke of the valve body being assisted by the flow of the liquid.
