ABSTRACT:
This disclosure relates to a variable length pipe assembly for connection between a pump-motor unit and a manifold. The assembly is particularly useful in a gasoline dispensing system of a service or filling station. The assembly comprises an inner pair of pipes and an outer pair of pipes. The pipes of the inner pair have telescoped portions and outer ends that are connectable to the pump-motor unit and the manifold. The pipes of the outer pair also have telescoped portions and outer ends that are connectable to the pump-motor unit and the manifold. The inner pair is mounted within the outer pair, a first passage being formed within the inner pair and a second passage being formed by the annular space between the inner pair and the outer pair. A seal is provided between the telescoped portions of the inner pair and another seal is provided between the telescoped portions of the outer pair, and a clamp is provided for securing together the telescoped portions of the outer pair. One of the first and second passages forms a liquid flow conduit between the pump-motor unit and the manifold, and the other of the passages forms a conduit for electric power lines leading to the pump-motor unit.
