Title: Actuating valve for pressure cooker
Inventor: JIYANKARURO BERUTSUTSUI
IPC: F16K17/04
Filed: 1990-09-28
Abstract: PURPOSE: To easily change temperature in a cooker with simple structure by providing a closing member of a gravity operated valve with first and second seal seatings, providing an internal duct with third and fourth seal seatings, and making the technical sections of the first and third seal seatings and second and fourth seal seatings different. CONSTITUTION: A second seal seating 23 forms technical section S11 of minimum value with pressure P applied thereto, to close a valve 1 in cooperation with a fourth seal seating 11. Pressure in a duct 9 which is the same pressure as the pressure in a cooker acts in a direction of lifting a pin 17 and opens the valve 1 with the product force F1 of the pressure P and the technical cross section S11 of the second seal seating 23. When the weight of a closing member 3 is made H, a valve opening condition is F1 >H. In order to lift the weight H at low pressure P in the case of the weight H being the same, S11 is to be made large. A knob 17 is turned until the pin slips out of its axial position.  The technical section S11 is therefore enlarged by the mutual action of first and third seal seatings, so that the valve 1 is opened at lower pressure P in the cooker, and liquid in the cooker can only reach low temperature.
