Abstract
An oil separator includes a housing into which mixed gas in which unburned gas and engine oil are mixed with each other is introduced from a crank case; a centrifuge mounted in the housing and generating centrifugal force to the mixed gas to thereby separate the engine oil from the mixed gas; and a filter separator mounted in the housing and filtering the engine oil in the mixed gas. Since the engine oil is primarily separated through the centrifuge and secondarily separated through the filter separator, engine oil separation efficiency is improved as compared to the related art, and the same amount of gas may be treated even with a small size as compared to the related art.
Claims18
An oil separator comprising:
- a housing into which mixed gas of unburned gas and engine oil is introduced from a crank case;
- a centrifuge mounted in the housing and generating centrifugal force to the mixed gas to thereby separate the engine oil from the mixed gas;
- and
- a filter separator mounted in the housing and filtering the engine oil in the mixed gas,
- wherein the centrifuge includes an induction rib formed in the housing so as to induce the mixed gas toward an inner side wall surface of the housing, and
- wherein the induction rib includes:
- a straight rib extending from an introduction pipe attached to the housing toward the inner side wall surface of the housing;
- and
- a curved rib extending from the straight rib so as to be curved to thereby form a spiral shape together with the straight rib.
An oil separator comprising:
- a housing into which mixed gas in which unburned gas and engine oil are mixed with each other is introduced into a side surface;
- a centrifuge provided in the housing so as to generate centrifugal force to the mixed gas to primarily separate the engine oil;
- a filter separator provided in the housing so as to be positioned on an upper end of the centrifuge and secondarily separating the engine oil from the mixed gas from which the engine oil is primarily separated;
- and
- a diaphragm provided in the housing so as to open and close a gas discharge pipe discharging the mixed gas from which the engine oil is separated through the centrifuge and the filter separator to the outside of the housing,
- wherein the centrifuge includes an induction rib formed in the housing so as to induce the mixed gas toward an inner side wall surface of the housing, and
- wherein the induction rib includes:
- a straight rib extending from an introduction pipe attached to the housing toward the inner side wall surface of the housing;
- and
- a curved rib extending from the straight rib so as to be curved to thereby form a spiral shape together with the straight rib.
An oil separator comprising:
- an oil discharge pipe extending along a first direction;
- a gas discharge pipe extending along a second direction different to the first direction;
- a separation chamber, extending along the first direction, including a first through hole connected to the oil discharge pipe and a second through hole connected to the gas discharge pipe;
- an introduction pipe protruding from a side wall of the separation chamber;
- a centrifuge disposed in the separation chamber and including a plurality of ribs protruding from a bottom wall in which the first through hole is formed;
- and
- a filter including a plurality of fine through holes and disposed between the centrifuge and the second through hole.
