Abstract: This disclosure illustrates and describes a filler valve assembly including a fluid pressure-activated upper control valve, a spring for urging the control valve closed, a fixed lower flow control valve, a nozzle slidably mounted in the lower end of the valve body, a second spring for normally urging the nozzle into a capillary seal relationship with the lower flow control valve, and spacer means extending between the nozzle and the upper control valve. Upon receiving a measured volume of fluid under pressure from an external source, the upper control valve is opened, causing the nozzle to move relative to the fixed lower flow control valve and thereby discharge a measured volume of fluid product into a container therebelow.

Abstract: A plug for sealing a sewer or drain conduit and for simultaneously filling the conduit so that the drainage system may be inspected for leaks. A tubular bulb made of an elastomeric material has fluid under pressure supplied to its internal cavity from one end. The bulb expands laterally of its longitudinal axis to thereby seal the conduit in which it is located. Thereafter, a spill over valve coupled to the other end of the bulb releases fluid from the bulb while maintaining the expanded size of the bulb and the sealing engagement between the bulb and the conduit. The bulb may have an external waffle surface to enhance sealing and reduce the likelihood of bulb rupture from sharp pipe edges. The spill over valve includes external channels through which fluid may pass upon sufficient expansion of the overlying bulb. Embodiments are disclosed which include a second bulb for sealing a branch conduit.
