VARIABLE VALVE ACTUATOR INTEGRATED WITH VALVE BRIDGE

摘要

PURPOSE: A variable valve actuator integrated with a valve bridge is provided to improve the variable control performance with increasing a response speed by reducing a volume of an operating circuit and hydraulically operating chamber. CONSTITUTION: A variable valve actuator integrated with a valve bridge comprises an actuator mechanism and a variable control mechanism, an actuator piston(320), and an actuator spring(330). T The actuator piston is inserted inside a valve bridge(310). Oil passed through an oil path(525) is discharged through an oil supply path(325) of the actuator piston. The actuator spring is inserted inside the actuator piston, and applies elastic force to the actuator piston. The variable control mechanism is placed under the actuator piston. The variable control mechanism is moved with supplied oil through the oil supply path, and changes an ascending and descending height of the actuator piston.
