ABSTRACT:
A siphon assembly includes a tube connecting a fluid source with a fluid receiver and a priming valve attached to the source end of the tube. The priming valve includes a body having an inlet port and a neck having an outlet port. The inlet and outlet ports are connected by a flow cavity extending through the body and neck. A valve member comprised of a metal ball is received in a seat near the inlet port of the body. Stop ribs are provided in the flow cavity where the body transitions to the neck to receive and centrally position the ball during siphon flow to provide substantially smooth, rapid fluid flow through the valve during siphoning. The body is comprised of a housing and an end ring attached to the housing. The two-piece body may be assembled by welding or alternatively the housing may have an annular flange on its inner surface that mates with a locking tab on the end ring to provide secure attachment. The end ring is fluted to allow continuous siphon flow when the valve sits flush against a surface of the fluid source.
