Lost motion actuator with damping transition |
摘要 |
A lost motion hydraulic actuator for use between a cam and a valve of an internal combustion engine is provided with internal communication ports that are controlled by a piston to provide sequential closing of the ports during closing of the engine valve to reduce hydraulic shock and hammering noise as fluid is gradually directed exclusively through a damping orifice during valve seating.
