DISPOSICION PERFECCIONADA EN VALVULAS ACCIONADAS POR BIMETALPARA PLANCHAS DE VAPOR

摘要

A steam valve for a steam iron has a vertically movable closing shaft (3) operable to open the valve when steam-forming temperature is reached in a steam forming chamber (2) and is rotatable by an external control (8). A shaft-carrying member (6) has a lateral projection (7) co-operating with a cam (12) on the bridge portion of a yoke (9) of which the arms are provided with projections (10) which co-operate respectively with bi-metallic elements (14, 15) located above the chamber (2). Operation of the valve is determined by the angular position of the shaft carrying member (6) relative to the yoke (9) and by operation of the devices (14, 15).
