(1) Slave pistons (2) Solenoid valve (3) Valve connector (4) Master cylindersThe CAT compression brake consists of identical housing assemblies. Each housing assembly is positioned over two cylinders. The housing assembly is mounted to the supports for the rocker arm shaft with studs and nuts. The rocker arm and the exhaust bridge assembly are used to transfer force from slave pistons (1) to the exhaust valves. Master cylinders (4) transfer lifting force from the fuel injector rocker arm to hydraulic force for the brake. The brake logic signal for the CAT compression brake is carried to solenoid valve (2) by signal wires that connects at valve connector (3) . This is done in order to activate the CAT compression brake on the two cylinders of the engine.The control circuit for the CAT compression brake permits the operation of either one or multiple compression brake housing assemblies. This provides progressive braking capabilities with the retarding effect of numerous cylinders in the engine.Operation of the CAT Compression Brake

The engine oil is pressurized by engine oil pump (14) . The engine oil supply for the CAT compression brake is supplied through rocker arm shaft oil passage (13) . Actuator valve (5) controls the flow of the supply oil in the compression brake housing.When the actuator valve is activated by a signal from the ECM, low-pressure oil passes from the actuator spool supply port (P) to actuation port (A) . The oil flow opens check valve (1) and flows into high-pressure oil passage (2) . Oil is supplied to slave piston (7) and master piston (4) . This engine oil pressure overcomes master piston spring (8) . The piston is forced downward toward fuel injector rocker arm (12) . Oil fills the cylinder for the master piston and the high-pressure oil passage between the master piston and the slave piston. The master piston follows the movement of the fuel injector rocker arm. The master piston moves upward with the fuel injector rocker arm. The movement of the master piston causes a flow of high-pressure oil that closes the circuit check valve. The closed check valve causes pressure to increase in the hydraulic circuit of the master piston, the slave piston, and the high-pressure oil passage.As the oil pressure in the high-pressure oil passage is increased by the movement of the master piston, the slave piston is forced downward in the bore.
