Abstract

A safety device for preventing overpressure for a pressure cooker comprising a cooking pan (1) and a lid (10) provided with a handle connected to the lid by a leaf spring (21). The safety device comprises at least a safety valve (30) is mounted on the leaf spring and on the lid, characterized in that one or a plurality of safety valves are mounted in a sealed manner in a drilling in the leaf spring so as to be interposed between the leaf spring and the lid and resiliently supported against the lid and obscure the evacuation hole in the lid.

Description

technical field [0001] The present invention relates to the general technical field of a safety device against overpressure for a perforated pressure cooker, having at least one safety valve connected to the lid and attempting to allow steam to escape in case of overpressure. [0002] The invention particularly relates to a safety device for preventing excessive pressure of a pressure cooker with a hole. The pressure cooker includes a pot body and a pot cover with a cover handle fixed on the pot cover through a spring sheet. The device includes at least one Spring leaf and safety valve on the lid. [0003] The invention also relates to a pressure cooker equipped with such a safety device. Background technique [0004] It is known that pressure cookers can usually be fitted with safety devices against overpressure and, as a general rule, pressure cookers have several safety components which can successively relieve the failure of any other individual safety device. [0005]...
