<P>PROBLEM TO BE SOLVED: To provide a gas-liquid separating device of a four-stroke engine further ensuring gas-liquid separation of oil, oil mist, and blowby gas such that the oil is not discharged into a combustion chamber. <P>SOLUTION: The four-stroke engine 1 has a tool in one end of the rod 60 in a longitudinal direction and is used fixed to the other end of the rod 60 in the longitudinal direction. The four-stroke engine 1 includes: an oil circulation pathway; and a gas-liquid separating chamber 70 configured to separate oil from blowby gas. The gas-liquid separating chamber 70 includes: an inflow part 203 into which the blowby gas is introduced from the oil circulation pathway; oil discharge parts 204 configured to flow the oil separated from the blowby gas back to the oil circulation pathway; and a blowby gas discharge part 400 configured to discharge the blowby gas not containing oil mist from the gas-liquid separating chamber 70 and supplies the blowby gas to an intake passageway to a combustion chamber. The oil discharge parts 204 are formed as openings on at least two corners in a lower part of the gas-liquid separating chamber 70 in the longitudinal direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
