Abstract:
A manifold assembly for pneumatically interconnecting an engine to a brake booster and for pneumatically interconnecting an inlet of an electrically-driven vacuum pump to the brake booster and an outlet of the vacuum pump to the engine, Wherein the manifold assembly comprises an open-top manifold housing coverable by a manifold cover, and wherein the open-top manifold housing has:a) an engine port pneumatically communicable with the engine; b) a booster port separate from the engine port and pneumatically communicable with the brake booster; c) an orifice pneumatically communicable with the inlet of the vacuum pump; d) an engine check valve which allows pneumatic flow from the booster port to the engine port but substantially blocks pneumatic flow from the engine port to the booster port; and e) a vacuum-pump check valve which allows pneumatic flow from the outlet of the vacuum pump to the engine port but substantially blocks pneumatic flow from the engine port to the outlet of the vacuum pump.
