Latest Patents

One of Kohara's notable inventions is the "Non-leaking non-dripping liquid jet pump". This ingenious design includes a mechanism where an intra-container liquid is sucked into a cylinder through a suction valve by vertically moving a member up and down. The intra-cylinder liquid is then jetted out of a nozzle via a discharge valve. Noteworthy features of this patent include a series of protruding ribs within the cylinder, which enhance fluid flow and prevent leakage. Engagement recessed portions in the ribs are designed to secure a coil spring that biases the vertically movable member, allowing for optimized liquid movement on both sides of the spring's lower edge.
