Abstract
A steam pressure cooker (1) is described, which is provided with a lid (2) and a pressure relief valve (8), comprising a valve seat (7a), a valve body (9) adapted to have a load applied thereto in the direction of the valve seat (7a) by means of a spring (11) and an adjustable spring abutment (12), which is adapted to be displaced from an operative position in which the valve body (9) is pressed onto the valve seat (7a) to a steam-discharge position in which the valve body (9) is relieved of the load to such an extent that the steam can escape and which, for the purpose of cleaning, can be removed from the lid (2) to such an extent that the pressure relief valve (8) is freely accessible. In order to permit a better accessibility for the purpose of cleaning the pressure relief valve, without there being any necessity of disassembling the pressure relief valve and its support into their component parts, the spring abutment (12) is formed on a pivotable flap (14, 68) at which the valve body (9) is guided and supported and a control means (16, 40, 48, 56, 72, 75) is provided with the aid of which the flap (14, 68) can be pivoted from the operative position to the steam-discharge position as well as to the cleaning position and back.
