ABSTRACT:
A spray system is disclosed for forming directed streams of liquid under pressure. A supply conduit having an open end and a manifold communicating with a plurality of spray nozzles and having an inlet conduit with an open end cooperate for insertion of the inlet conduit into the supply conduit to connect the manifold to the supply conduit, the manifold is placed near the supply conduit in a predetermined but misaligned position. A plate having a slot defines at least a portion of a pair of cam surfaces and a wash arm formed on the manifold defines a cam follower. Rotation of the inlet conduit about its central axis causes the cam follower to contact and cooperate with the cam surfaces to produce lateral force along the inlet conduit, thereby forcing the same into fluid-tight engagement with the supply conduit. Alternatively, a pin and a cooperating opening may be provided, so that placement of the pin within the opening enables pivotal motion of the inlet conduit for moving the same into engagement with the supply conduit.
