Abstract
A water refilling plug for automatically filling battery cells has a cylindrical plug housing that includes a connector fitting for water delivery into a housing, as well as a valve, actuated by a float, having an annular valve body and a conical valve seat. The valve is arranged between an inflow channel and an outflow channel leading into the battery cell. In accordance with the invention, swirl-generating deflection channels are arranged between the annular inflow channel and the conical valve seat in a pattern distributed over a circumference in the plug.
Claims3
A water refilling plug for automatically filling battery cells comprising:
- a cylindrical plug housing;
- a connector fitting coupled to the cylindrical plug housing for water delivery into the cylindrical plug housing;
- and
- a valve having an annular valve body and a conical valve seat, the valve being arranged between an inflow channel and an outflow channel leading into a battery cell;
- wherein swirl-generating deflection channels are recessed into a cylinder wall of the valve over a circumference of the wall between the inflow channel and the conical valve seat,
- wherein the cylinder wall is located between a valve cylinder centeredly attached in the cylindrical plug housing, and an inner cylinder on which the conical valve seat is provided, the swirl-generating deflection channels proceeding obliquely with respect to a radial direction of the cylinder wall and opening substantially tangentially into an inner space of the valve cylinder above the valve seat, and
- wherein the swirl-generating deflection channels proceed obliquely upward from the inflow channel.
