Title:
LATCHED RESET MECHANISM FOR ENGINE BRAKE
Document Type and Number:
WIPO Patent Application WO2002101212
Kind Code:
A3
Abstract:
A method and rocker arm assembly (100) for actuating an engine valve are disclosed. The rocker arm may include an integrated hydraulic circuit (110, 118, 120) used to control a lost motion piston (130). A reset piston (160) may be included in the rocker arm to selectively reset the position of the motion piston (130). A control piston (170) may also be included in the rocker arm to selectively lock the reset piston (160) into a reset position. The rocker arm assembly (100) may be used to achieve compression-release or bleeder braking, main intake, main exhaust, brake gas recirculation, and/or exhaust gas recirculation valve events.
