ABSTRACT:
A vehicle vacuum power system which insures sufficient vacuum power to operate a vacuum brake booster and a vacuum operated road speed control system. Because of the low vacuum, high flow rate needs of a cruise control system, the cruise control is connected directly to the engine manifold through a check valve. A small orifice from the vacuum pump in parallel with engine manifold vacuum provides sufficient vacuum for the cruise control when the manifold vacuum is not sufficient. The vacuum pump is in series with manifold vacuum and is operated in response to a pressure switch which allows the pump to run only when brake booster vacuum is low. Manifold vacuum is sufficient most of the time, but the orifice to the cruise control tends to cause a fast loss of brake booster vacuum, causing the vacuum pump to run when it is not actually needed. The vacuum regulator shuts off the flow through the orifice when it is not needed, considerably reducing the pump operational time. The regulator is a two-piece housing with a spring loaded diaphragm controlling a regulator port. Atmospheric pressure is on one side of the diaphragm and engine manifold vacuum is on the other.
