Beschreibung
Zusammenfassung:	This invention describes an improved plug type sphere launching and receiving device for pipeline. It involves a housing with a longitudinal passage for the spheres. There is a cylindrical boring perpendicular to the longitudinal channel and a cylindrical plug is inserted into this boring. There is a channel through the plug coaxial with the main channel of the housing and there is a bored opening along the axis of the plug so that a sphere can be inserted into the line from the bottom end of the plug. The housing has a downward extension in line with this opening in the plug so that spaces provided for one or more spheres to be received as they travel down the pipeline to the housing and into the plug. The bottom end of this extension is closed with a screw type sealed closure. Means are provided in the housing surrounding the central passage to seal tightly against the surface of the plug. The plug itself is not exactly cylindrical. Each half of the circumference is turned from a center or rotation which is displaced from the central axis of the plug so that by rotating the plug 90 DEG its effective radius against the seals is increased by the amount of the eccentricity. This provides a strong positive seal when the valve is closed. When the valve is open a perfect seal is not required.
