摘要: A variable valve actuation system is disclosed for providing exhaust to at least one component downstream of an engine. The system includes a supply of low pressure fluid, an engine fluid sump, and an exhaust valve disposed in an engine cylinder. The system also includes a hydraulic actuation system operably connected to the exhaust valve of the engine cylinder and a braking control valve operably connected to the hydraulic actuation system. The system further includes a device for accumulating fluid and a device for fluidly coupling the hydraulic actuation system to the accumulating device.

摘要: A variable valve actuation system is disclosed for providing exhaust to at least one component downstream of an engine. The system includes an exhaust valve disposed in an engine cylinder and a hydraulic actuation system. The system also includes a braking control valve, a supply of hydraulic fluid operably connected to the hydraulic actuation system, and an exhaust valve actuating device operably connected to the valve actuation system. The exhaust valve actuating device is operable to affect the exhaust valve to open within the engine cylinder. The system further includes a device for controlling a position of the exhaust valve actuating device relative to a position of the exhaust valve. The controlling device is operably connected to the supply of hydraulic fluid.

摘要: A compression release brake system 10 includes a hydraulic apparatus 12 for controllably opening at least one exhaust valve 14 of at least one cylinder 16 of an engine in response to motion of a cam actuator 12. The system 10 includes a master piston assembly 40 having a master piston 42 engageable with the cam actuator 12. The master piston 42 includes a compressible piston pin 56. A slave piston assembly 44 is hydraulically linked to the master piston assembly 40 and includes a slave piston 46 engageable with the at least one exhaust valve 14.
