Abstract: A water supply valve cartridge in which a flow rate control rotary disk has a reduced size, so that surface friction between the flow rate control rotary disk and a flow rate control fixed disk is minimized, thus improving manipulation efficiency of the water supply valve while opening or closing the valve, and which does not sensitively respond to flatness allowance due to the reduced size of the rotary disk, thus executing stable opening and closing operation. The flow rate control fixed disk (140) has water discharge holes (142). The flow rate control rotary disk (150) has a diameter to cover only the area around the water discharge holes (142), with a pair of flow rate control grooves (151) formed on the rotary disk (150) to open only the water discharge holes (142) during rotation.

Abstract: The present invention relates to a water valve. More particularly, the present invention relates to a water valve having a valve cartridge for controlling the temperature and flow of supplied hot/cold water, wherein a discharge path is blocked, or a direct water path or a shower path is selected and the amount of water flow is controlled, by changing the direction of rotation in a flow control section. The present invention can exert various functions through a simple structure and operation, as the water valve can be turned on or off, a direct water path or a shower path can be selected, and the flow of the selected path can be controlled, through manipulation of a flow control unit. In addition, the present invention has a simple structure and is easily installed by combining a water valve and a nozzle head.

Abstract: A cartridge of a water supply valve that controls the flow rate and temperature of water without causing interference between flow rate control operation and temperature control operation of the valve. In the cartridge, a flow rate control knob (12) angularly moves forwards and rearwards and actuates a control lever (14) to open or close cold and hot water supply holes (1a and 1b). A temperature control knob (13) is coupled to the flow rate control knob (12), linearly moves leftwards and rightwards, and actuates the control lever (14) to control the opening ratios of the water supply holes. Thus, this cartridge does not change the existing temperature of water during flow rate control operation or change the existing flow rate of water during temperature control operation. This invention reduces the quantity of water to be unnecessarily wasted and, at the same time, prevents undesirable consumption of excessive energy.

Abstract: A water control valve, which has one valve cartridge to control the temperature and flow rate of hot water, cold water or a mix of hot and cold water only through rotating motions, is disclosed. The valve cartridge (100) has a first fixed disk (120) to guide hot and cold water into the valve cartridge, a rotary disk (130) to control the flow rate of hot and cold water from the first fixed disk, thus controlling the temperature of water, a second fixed disk (140) to guide controlled water in the cartridge, a temperature control unit (170) to rotate the rotary disk during rotation of a temperature control lever, the moving unit (150) to linearly move toward or away from the second fixed disk, thus controlling the flow rate of discharged water, and a flow rate control unit (160) to cause linear movement of the moving unit by rotation.

Abstract: The present invention relates to a water control valve cartridge, which includes a single control knob that is capable of controlling the flow rate and the temperature of water, the control knob being manipulated within a predetermined planar area and controlling the flow rate or the temperature of water exclusively, or controlling the flow rate and temperature of the water at the same time, the control knob also reducing the number of elements of the cartridge and simplifying the combined construction of the cartridge, and improving the construction for manipulation of the control lever.

Abstract: In an apparatus and a method for indicating initial distance to empty (DTE) at completion of fueling, the initial DTE is calculated based on a fluctuating fuel consumption rate and is compensated by a compensation value so that DTE can be determined with more accuracy compared with an initial DTE calculated based on the fixed fuel consumption rate. The DTE to be confirmed can be thereby prevented from abruptly changing.
