Abstract: PURPOSE:To prevent a solenoid from roaring by providing the solenoid for driving to open and close a value for allowing a bottom face opening part of a rice washing container to communicate with the inside of a pot, a transfer means for transmitting an operation of the solenoid to the valve, and an elastic body for connecting the transfer means and the solenoid. CONSTITUTION:When a full-wave-rectified pulsating current is applied to a solenoid 77, the solenoid 77 operates, and as for a spring 1, a spring shaft 2 moves to the right side and contracts and energy is stored. A push rod 75 moves immediately to the head part of a center shaft 61, but is balanced with frictional force and moves since packing 59 comes into contact with the inside surface of a rice washing container 53. Energy stored in the spring 1 is transmitted to the push rod through a spring receiving cylinder 4, a link shaft 5, and solenoid link 76, and it is balanced with the downward movement of the center shaft 61 and the spring 1 expands gradually. As for the solenoid, when the center shaft 61 moves to the lower maximum compressed position, and thereafter, the electric conduction is stopped, a valve 54 moves upward by the energy of the center spring, and the spring 1 is reset to a state before the electric conduction. An operation time of the solenoid is a short time and the generation of roaring can be prevented.

Title: Rotary valve
Inventor: YUURI ZUROBINSUKII
IPC: F16K3/08
Filed: 1991-02-21
Abstract: PURPOSE: To simply constitute an inexpensive rotary valve by displacing the bottom face of a cover to an installation side by a low presser in a valve and sealingly supporting and rotatably attaching the valve cover to a valve main body so that the ambient air is prevented from entering into the valve. CONSTITUTION: A groove and a holding ring 78 are positioned apart in the bottom side of a valve main body 20. This becomes possible, because a valve cover 22 axially moved to the valve main body 20 so that the bottom face moves inversely to the valve installation face. When the valve is so set as to communicate an exhaust space with a vacuum generator, the pressure in the valve is low and the ambient air pressure is applied to the upper side surface of the valve cover 22. By pressurizing the valve cover 22 downward, an elastic seal member 59 is smashed against the valve installation face side. The ambient general state thus helps the vacuum seal mechanism of the valve.
