Title: Automatic icemaker and refrigerator
Inventor: YAMAMOTO KAZU
IPC: F25D11/02
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to suppress a food storage space and to ensure uniform water amount by installing a feed water tank in the recess formed at the partition wall for partitioning in a refrigerator. SOLUTION: The sub-chamber 7 in a feed water tank 10 is filled with water during the operation waiting of an automatic icemaker. When the icemaker starts operating to the stage of water supplying operation, a self-supply type pump 24 starts rotating in the direction for feeding water to an icemaking tray 27 side while engaging its gears. The water amount of the sub-chamber 7 is decreased in proportion to the number of revolutions of the pump 24. Since the water is introduced into the sub-chamber 17 only from a small-diameter hole 15, it is slight as compared with the water amount carried out from the sub-chamber 17 by the pump 24.  The water level in the sub-chamber 17 becomes substantially zero, and the pump 24 is rotated to the state that no water remains in a pipe 13, suction pipe 22, pump 24 and discharge pipe 26 and stopped, thereby finishing the supply of the water to the tray 27.

Abstract: PURPOSE: To control the pressure of fluid such as town gas on the downstream side of a pressure regulator to a required level, by controlling a pressure reducing valve disposed at a portion of a pipe for feeding the fluid such as town gas.  
     CONSTITUTION: In a time period, for instance, from 16 to 20 o'clock, when the demand for town gas is increased, a solenoid valve 15 is opened by a timer 16. Resultantly, primary pressure is transmitted to a pressure chamber 9 via a conduit 14, so that an auxiliary diaphragm 10 is displaced downward until a stopper piece 13 comes into abutment with the top of a driving unit 2a. Therefore, a pressure regulating spring 8 is compressed and its spring force is increased, so that the secondary pressure is kept at a relatively high value P 2b . On the other hand, after passing of the above time period, the solenoid valve 15 is closed, pressure in the pressure chamber 9 is released gradually to the secondary side via a flow throttle 18, so that pressure on the secondary side is transmitted to the chamber 9 and the secondary pressure is kept at a relatively low value P 2a .
