  • Manifold having outlets equally spaced from inlet
    Patent number: 5937907
    Abstract: A manifold having a plurality of outlets each equally spaced from the inlet in the radial direction is provided. The equal spacing of the outlets from the inlet provides substantially equal flow across each outlet. Preferably, the manifold has a main body, an inlet coaxial with the main body and a plurality of outlets carried by the main body equally spaced from the inlet. A stop valve can be provided adjacent each outlet to allow each outlet to be independently closed while maintaining a substantially equal flow through the open outlets.
