An oil separator arrangement for an internal combustion engine incorporates a vortex chamber oil separator with a vortex chamber extending in a longitudinal direction, where the vortex chamber includes a wall extending in a longitudinal direction, a gas inlet, and a gas outlet opening. The gas inlet is disposed tangential to the wall for tangentially blowing-in of blow-by-gas into the vortex chamber, so that at least one gas vortex flow rotating helically along the wall in the longitudinal direction is generated, where at least one further oil separator is connected in parallel to the vortex chamber oil separator. The further oil separator incorporates a separation chamber with an inlet-side spring tongue automatically controlled by the applied blow-by-gas, and a baffle wall disposed downstream the spring tongue.
An oil separator arrangement for an internal combustion engine, comprising a vortex chamber oil separator with a vortex chamber extending in a longitudinal direction, said vortex chamber comprising a wall extending in a longitudinal direction, a gas inlet, and a gas outlet opening, said gas inlet being disposed tangential to said wall for tangentially blowing-in of blow-by-gas into said vortex chamber, so that at least one gas vortex flow rotating helically along said wall in said longitudinal direction is generated, wherein at least one further oil separator is connected in parallel to said vortex chamber oil separator, wherein each said at least one further oil separator comprising a separation chamber with a second gas inlet and an inlet-side spring tongue automatically controlled by the applied blow-by-gas, and a baffle wall disposed downstream of the spring tongue, wherein the inlet-side spring tongue comprises a leaf spring clamped in a cantilever manner at a first end, wherein the inlet-side spring tongue is arranged inside the separation chamber, wherein the inlet-side spring tongue is arranged such that blow-by-gas entering through the second gas inlet into the separation chamber is deflected around a second end of the leaf spring through an opening gap such that particles contained in the blow-by-gas flow are separated from the blow-by-gas flow, such that oil separation in the at least one further oil separator is effected by the spring tongue.
A cylinder-head cover for an internal combustion engine with an integrated oil separator arrangement, comprising a vortex chamber oil separator with a vortex chamber extending in a longitudinal direction, said vortex chamber comprising a wall extending in a longitudinal direction, a gas inlet, and a gas outlet opening, said gas inlet being disposed tangential to said wall for tangentially blowing-in of blow-by-gas into said vortex chamber, so that at least one gas vortex flow rotating helically along said wall in said longitudinal direction is generated, wherein at least one further oil separator is connected in parallel to said vortex chamber oil separator, wherein each said at least one further oil separator comprising a separation chamber with a second gas inlet and an inlet-side spring tongue automatically controlled by the applied blow-by-gas, and a baffle wall disposed downstream of the spring tongue, wherein the inlet-side spring tongue comprises a leaf spring clamped in a cantilever manner at a first end, wherein the inlet-side spring tongue is arranged inside the separation chamber, wherein the inlet-side spring tongue is arranged such that blow-by-gas entering through the second gas inlet into the separation chamber is deflected around a second end of the leaf spring through an opening gap such that particles contained in the blow-by-gas flow are separated from the blow-by-gas flow, such that oil separation in the at least one further oil separator is effected by the spring tongue.
