Abstract
Embodiments of the present invention provide an endoscopic fluid control valve. By having just one fluid outlet, the structure of the endoscopic fluid control valve is made simpler with interior space saving. There is no need for a one-way check valve at an operational portion of the endoscope to prevent fluid backflow, and this makes it easy to clean. An embodiment includes valve housing, valve stem, valve core, elastic component, button, first seal, second seal, third seal, fourth seal, gas inlet, fluid inlet and fluid outlet.
