Abstract

PURPOSE: To open and close an intake and exhaust valve of an internal combustion engine under conditions fit for each operation condition, by varying the quantity of the lift of both arms of a locker arm in a driving gear of said intake and exhaust valve by oil pressure.
CONSTITUTION: An intake and exhaust valve 3 is opened and closed by means of a cam 1 of a cam shaft 2 through a locker arm 5. The locker arm 5 consists of a second arm 8, to which a ringed wall 14 is connected, and a first arm 7, which is turned in the ringed wall 14 and to which an elliptic rotor 15 is connected. A locker shaft 6, which is provided with connecting holes 24, 25 and is equipped with an internal space 23 that oil is fed, is disposed into the rotor 15 while a relief valve 17 is arranged which is mounted into an oil pressure chamber 21 and has a balance hole 28 communicated with a first oil pressure chamber 18. When oil is hermetically sealed into the first oil pressure chamber 18, both arms 7, 8 are fixed; when connecting holes 20, 24 communicate a first oil pressure chamber 19, clearances are formed to the arms 7, 8.
