ABSTRACT:
The present invention relates to a co-axial master piston for use in providing hydraulic fluid to effectuate a compression release braking function and hydraulic fluid to effectuate an exhaust gas recirculation function. In particular, the coaxial master piston includes an inner master piston driven by an exhaust cam to provide the hydraulic force to cause the compression release braking function. An outer piston, driven by the same exhaust cam, provides the hydraulic force to cause the EGR function during positive power operation of the engine and during compression release braking when required.
