Abstract:
1. An apparatus for actuating valves in vehicles in a variable valve control manner, comprising: an eccentric cam mounted on a cylinder head and rotating with power transmitted from a crank shaft; a high-pressure pump connected to an oil pump, wherein a first end of the high-pressure pump is pushed by the eccentric cam when the eccentric cam rotates, converting low-pressure oil supplied from the oil pump into high-pressure oil; a high-pressure rail connected with the high-pressure pump to accommodate the high-pressure oil from the high-pressure pump and store the high-pressure oil therein; an operating cylinder connected with the high-pressure rail and having a plunger pushing an intake or exhaust valve with a pressure of oil received from the high-pressure rail; a connection link provided between the high-pressure pump and the eccentric cam, a middle member pivotally coupled with a cam shaft and the connection link so as to rotate about the cam shaft.
