A pressure-limiting valve has a closure member (5) which, in its closed position, rests with initial stress against a valve seat (4) and has, on the side towards the valve seat (4), a shoulder (6) which can be formed by a circumferential flange (7) on the closure member (5). This induces enlargement of the opening stroke upon a slight opening of the closure member (5) as the flow strikes against the shoulder (6).

Pressure-limiting valve

A pole terminal is formed as an intermediate piece and has toward the bottom a clamping piece for fastening to a conventional battery pole and toward the top a pole body to which a conventional battery terminal can be fastened. In the pole terminal there are a Hall element and an evaluation electronics so that the current flow through the pole body can be measured.
