Abstract:
A compression brake actuating device for an internal combustion engine, said compression brake actuating device comprising:a brake actuator cylinder having a first cylinder port and a second cylinder port; a fluid conduit in fluid communication with said first cylinder port and said second cylinder port; a brake actuator piston positioned in said brake actuator cylinder, said brake actuator piston having an actuating surface; an actuator volume defined by said actuating and said brake actuator cylinder; a first piston passage through said brake actuator piston, said first piston passage being adapted to fluidly connect said first cylinder port with said actuator volume; and a second piston passage through said brake actuator piston, said second piston passage being adapted to fluidly connect said second cylinder port with said actuator volume, said brake actuator piston being movable within said brake actuator cylinder to restrict fluid communication between said first cylinder port and said first piston passage, said brake actuator piston being movable within said brake actuator cylinder to restrict fluid communication between said second cylinder port and said second piston passage, said first piston passage being connected with said second piston passage.
