ABSTRACT:
A valve assembly for detecting leaks in fluid systems which includes an airtight transparent cup means at least partially filled with liquid and a plunger means provided with an orifice and a tube means interconnecting said orifice and liquid. The valve assembly is connected into the fluid line so as to allow the fluid to pass therethrough unimpeded. Depression of the plunger effectively closes the fluid line except for the passageway afforded by the orifice and the tube positioned in the liquid. The existence of a leak in the fluid system is thereby easily observed by a fluid flow through the liquid, i.e., bubbles, etc.
