Abstract
A manifold assembly for pneumatically interconnecting a brake booster to an engine and to an electrically-driven vacuum pump. A manifold housing has an engine port pneumatically communicable with the engine, a separate booster port pneumatically communicable with the brake booster, and an orifice pneumatically communicable with the vacuum pump inlet. An engine check valve substantially blocks pneumatic flow from the engine port to the booster port. A vacuum-pump check valve substantially blocks pneumatic flow from the engine port to the vacuum pump outlet.
