Abstract
An automatic safety valve for a timepiece, especially for a diving watch. The valve includes a valve head, a tube designed to be secured in a case of the timepiece, and an evacuation channel arranged so as to be in fluidic communication with the inside of the case when the safety valve is in an open configuration so as to evacuate an excess of fluid. The safety valve further includes a pressure regulator arranged inside the evacuation channel to maintain the outlet speed of the fluid.
Claims17
A crown head for a timepiece, comprising:
- a cap having a cover and an axial skirt;
- a tube designed to be secured in a case of the timepiece;
- a sealing gasket arranged between the tube and the axial skirt;
- a central pipe designed to be engaged with the tube, the central pipe and the cap forming an assembly able to be placed in different axial positions with respect to the tube;
- and
- a safety valve having an evacuation channel designed to be in fluidic communication with the inside of the case when the valve is in an open configuration so as to evacuate an excess of fluid,
- wherein the safety valve moreover comprises a pressure regulator arranged inside the evacuation channel to control the outlet speed of the fluid, and
- wherein the pressure regulator comprises a ball arranged to cooperate with a ball seat, the ball being arranged on the ball seat so as to obstruct the passage of a fluid in the evacuation channel when the internal pressure upstream from the ball is less than a predetermined value, the ball being dislodged from the ball seat when said internal pressure exceeds the predetermined value in order to establish said fluidic communication.
