Clack

Clack means to speak (about unimportant matters) rapidly and incessantly, originally from when Clacks' in England got their names for being royal court messengers. There is another version, of course, and that is it comes from the middle english work clakken, which comes from the Old Norse word Klaka which means thoughtless, prolonged talk...

clack

A valve that allows a liquid to pass in one direction only. It has a flap or poppet device to prevent back-flow. They can be found on the old style windscreen washer where a plunger is pushed to operate it.

Another place to find one is on a boiler where the injectors force the water into it but the pressure must not be able to pass back along the supply pipe.

The water is mixed with the steam in the injector and passes through the supply pipe via the clack valve into the boiler.
