• Fig. 1 of the drawing a section through the pressure valve 2 according to the invention is shown, wherein the pressure valve 2 is fixedly secured to a cover 4 of a pressure cooker, not shown in the drawing.
• the upper region of the pressure valve 2 is formed by a rotary handle 6, with which the pressure levels can be adjusted.
• the rotary handle 6 consists of a rotary lever part 8, which can be pivoted about the valve axis 10. For pivoting, an approximately radially outwardly projecting hand lever 12 is used. As is apparent from Fig. 1 and in particular from Fig. 2, the rotary lever part 8 is formed transversely to the valve axis 10 in an upper half 14 and a lower half 16 divided. The two halves 14 and 16 of the rotary lever part 8 are firmly connected to each other, by means of screws 18 which are screwed from below through the lower half 12 in the upper half 14.
• the pressure valve 2 further includes a pressure cylinder 20, a pressure spring 22 arranged therein, a valve outlet pipe 24 and a pressure pipe 26 surrounding it, in whose upper region projecting beyond the valve outlet pipe 24 a sealing body 28 is fastened.
• This consists of an elastic material, such as rubber, silicone or the like.
• a cylindrical valve body 30 which is fixedly connected together with the valve outlet pipe 24 to the cover 4.
• a cap nut 32 which is screwed onto a projecting through the lid 4 threaded end 34 of the valve outlet pipe 24.
• the cap nut 32 is provided with lateral through holes 36 which are connected to the inner cross section of the valve outlet pipe 24 and thus connect the pot interior with the external environment.
• An essential feature of the pressure valve 2 according to the invention is the smooth and targeted pivoting of the rotary valve.
• spring-loaded position pins 40 are arranged on the underside of the rotary lever part pointing in the direction of the valve body 30, while the valve body 30 has latching rollers 42 on its upper side facing the rotary lever part 8 for selectively receiving the position pins 40.
• the position pins 40 are disposed between the halves 14 and 16 of the rotary lever part 8. These are in the upper half 14 of the rotary lever part 8 receiving cylinder for each one position pin 40 and for this acted upon
• Compression spring 46 is provided in the lower half 16 of the rotary lever part 8 through holes 48 are formed for the cooperating with the locking recesses 42 position pin 40.
