Air compression systems for internal combustion engines are utilizing an integral part of the engine to produce the compressed air necessary for operating the brakes of a vehicle. The ability to produce compressed air from an integral part of the engine is important in order to reduce the cost and weight associated with the engine and to increase performance capability and reliability. The integral air compression system includes a valve means associated with one of a plurality of combustion chambers. A housing is connected to a cylinder head and has first and second bore. A master piston is disposed within the first bore to define a first oil chamber. A slave piston is disposed within the second bore to define a second oil chamber. A means fluidly connects the first and second oil chambers. The master piston is forced toward the first oil chamber when another one of the combustion chambers is in the exhaust stroke. The second oil chamber becomes pressurized and forces the slave piston to open the valve means during the compression stroke of the one combustion chamber allowing compressed air to flow through a passage in the head and into a storing means. A means for monitoring the pressure in the storing means is utilized to control the integral air compression system.
