    摘要： The present invention discloses a bypass valve and a water purifier comprising the bypass valve. The bypass valve comprises a valve housing and a valve core disposed in an inner space of the valve housing and capable of rotating in the inner space around an axial direction. The valve core comprises a first inlet and a first outlet disposed at intervals in an axial direction, a first annular seal fitted on an outer side surface of the valve core between the first inlet and the first outlet, and a first channel disposed within the valve core and communicating with the first inlet and the first outlet. The valve housing comprises a first opening and a second opening disposed at intervals in an axial direction, the inner space communicating with the first opening and the second opening, and a bypass opening provided on a side wall of the valve housing between the first opening and the second opening and communicating with the inner space and an outer space outside the valve housing. The bypass opening and the first circular seal are configured in such a manner that, when the valve core rotates, the first annular seal is capable of partitioning the bypass opening into two parts, and an axial position of a part of the first annular seal in contact with the bypass opening varies with the rotation of the valve core.

    摘要： A fluid valve system including a housing defining a plurality of flow paths and a flow control member moveably disposed and selectively positionable within the housing. The flow control member includes a passageway having a fluid inlet and a fluid outlet, wherein a cross-sectional area of the fluid inlet is larger than a cross-sectional area of the fluid outlet. When the flow control member is in a first position, a flow of fluid through a first flow path is permitted. When the flow control member is in a second position, the flow of fluid through a second flow path is permitted. When the flow control member is in intermediate third positions between the first position and the second position and/or a fourth position, the flow of fluid through the first flow path and the second flow path is permitted.

    摘要： A rotary valve rotated by an arm connected to a piston being driven by the pressurized fluid, either water or air. The orientation of the valve body in the valve housing will direct the fluid in one of two directions to move the piston. The arm of the rotary valve is connected to a cam that rotates a shaft connected to the valve body. Two cam rollers are biased towards the outer surface of the rotating cam member. The cam rollers provide a force to the cam to aid in the changing of the orientation of the valve body. There are two bump outs on the cam that correlate to the end of the piston movement so that the rotary valve does not stop at an end point of the piston stroke. The rotary valve may be is utilized in a chemical dosing or chemical application device that is driven by pressurized fluid.
