摘要

The box has a thermostat made up of a valve to block an opening of a passage emerging in a box. The valve is stressed against its seat by an elastic loading unit and moved away from the seat by a pressure unit reacting with heat. The box has two protrusions (10, 10) on an internal face of wall. The protrusions provide permanent support surfaces for clamp of the thermostat before and after installation of the box. An Independent claim is also included for a manufacturing process of a water outlet box.
