Title: Solenoid valve
Inventor: SAKAI TAKAO
IPC: F16K31/10
Filed: 1981-10-12
Abstract: PURPOSE:To prevent the burning of an A.C. solenoid valve for an open water tank, by constructing such that a core to be operated by an electromagnetic coil and a main valve which follows the core will function differently through a resilient member thereby preventing the overcurrent of the electromagnetic coil. CONSTITUTION:The spring characteristic of a spring 8 provided on a main valve section 2 is set outside of the coil burning spring load region while an auxiliary spring 9 is arranged above the core 4. When a biting occurs between a body 1 and the main valve 2, the core 4 will perform the predetermined stroke by the characteristic of the spring 8 to transmit the operating force to a spring stopper 6 thus to bring the spring 8 to the virtual full open position of the stroke S'v pushing solenoid valve. Consequently the core 4 will fully stroke to protect the electromagnetic coil 3 from the overcurrent. If the biting is released during the actuation of said coil 3, said coil 3 is deenergized but an auxiliary spring 9 will function as a remanence killer. Consequently the electromagnetic coil is protected from burning.

Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a pump pipe, by hanging a water-economizing weight having the same specific gravity as that of a water at the front end of the rubber pump pipe protruded into a flushing water tank from a chemicals-container. SOLUTION: A chemicals-feeder is constituted of a cleanser container 4, a pump pipe 11 made of a rubber elastic body protruded sideways into a flushing water tank 1, check valves 16, 10 provided at the inlet and the outlet of the pipe 11, and a water- conomizing weight 22 having the nearly the same specific gravity as that of water, hung down at the front end of the pipe 11. After urinating, when a specified volume of cleaning water is discharged, the water level becomes lower and the weight 22 is also lowered. Since the pipe 11 is squashed and hung down and the inside volume is decreased and the inside pressure is increased, the cleanser in the pipe 11 is added in the tank 1 through the valve 16. When the cleanser ceases to flow out, the cleaning water is replenished up to the water level 18.  The pipe 11 is returned to the horizontal free state and the inside volume is increased and the cleanser in the container 4 is filled in the pipe 11 through the check valve 10. In this way, since the pump pipe is returned to the free state during the long filled water period, and hence, the deteriorating deformation can be prevented.
