Abstract: An oil supply circuit for a cylinder deactivating system is provided to form an air discharge hole at one side of a low-pressure oil path, use the air discharge hole as an oil jet for lubrication of a timing chain, and prevent aeration in the low-pressure oil path. An oil supply circuit includes a first low-pressure oil path(LL1), a branch low-pressure oil path(BLL), and a second low-pressure oil path(LL2). The first low-pressure oil path is provided at an intake and connected to an intake tappet(5a) of a 5-cylinder(Cyl5) and an intake tappet(3a) of a 3-cylinder(Cyl3). The second low-pressure oil path branches to an outlet and is connected to an outlet tappet(5b) of the 5-cylinder. The second low-pressure oil path is connected to an outlet tappet(1b) of the 1-cylinder and the intake tappet of the 1-cylinder through an outlet tappet(3b) of the 3-cylinder. A high-pressure oil path(HL) is connected to each terminals of the first low-pressure oil path, the second low-pressure oil path, and the branch low-pressure oil path while being connected to a first oil control valve(OCV1) and a second oil control valve(OCV2).
