Patent ID: 8800531

Claim:
A compression brake system for an internal combustion engine having an engine block and a camshaft rotatable relative to the engine block, the compression brake system comprising: a cam follower assembly including a cam follower body having a first end supporting a roller disposed in contact with the camshaft and a second end defining contact point oriented away from the camshaft; and a brake actuator assembly having: a brake actuator piston; a master cylinder having a volume of fluid, the volume of fluid having a deactivated state, in which the volume of fluid has a first fluid pressure, and an activated state, in which the volume of fluid has a second fluid pressure that is higher than the first fluid pressure; a master piston slidably disposed in the master cylinder and hydraulically coupled to the brake actuator piston; and a master pin having a first end coupled to the master piston and a second end opposite the first end; the master piston moving to a retracted position when the master cylinder is in the deactivated state, in which the second end of the master pin is spaced from the contact point, and the master piston moving to an extended position when the master cylinder is in the activated state, in which the second end of the master pin mechanically engages the contact point, wherein the master piston is biased in the retracted position.
