PURPOSE: A device for restoring blow-by gas of an orifice type is provided to prevent generation of static pressure in a crankcase by maintaining flow of the blowby gas and to improve safety of an idle. CONSTITUTION: A device for restoring blow-by gas of an orifice shape comprises a cylinder head(1); a suction manifold(5) connected to a throttle body(3); an exhaust manifold(7) engaged with the suction manifold; a cam operating a suction/exhaust valve by being mounted on an upper portion of the cylinder head; a rocker cover(9) protecting the cam from foreign material and dust by covering the cam; an inlet pipe(11) installed on an upper portion of the rocker cover; an intake hose(13) connected tot eh inlet pipe; a PCV hose(15) arranged on an upper portion of the rocker cover; and a serge tank(19) engaged with the PCV hose; and an orifice(17) mounted on a side of the PCV hose. Thereby, the device for restoring the blowby gas of the orifice shape prevents generation of static pressure in a crankcase by maintaining flow of the blow-by gas.
