  • Direct pressure feed air bleed system
    Patent number: 7174866
    Abstract: A manifold assembly includes a pressure feed orifice that directly connects an inlet circuit to a control circuit of the manifold. This direct connection between the pressure inlet to the control circuit allows air to be bled out of the manifold assembly. Low pressure fluid in the assembly pushes out air through the orifice out of the assembly, ensuring prompt solenoid response during manifold assembly operation.
