摘要： An oil separating apparatus of an engine mounted on a shaking machine such as a rammer, for separating oil mist from blow-by gas and for feeding liquefied oil back to a crank chamber comprises a rocker chamber having an enlarged volume and mounted on a cylinder head, a breather chamber mounted on the rocker chamber, a blow-by gas port provided on the locker chamber for communicating the rocker chamber with the breather chamber, and an oil passage having an enlarged passage area for communicating the crank chamber with the rocker chamber. The constituted oil separating apparatus separates oil mist from blow-by gas almost completely and returns liquefied oil to the crank chamber swiftly, even when the engine produces a large amount of oil mist due to violent vibrations of the shaking machine.

摘要： In a gas-liquid separation device in a vibrator engine according to the present invention, a crank chamber and a rocker chamber communicate with each other through an oil delivery passage, and a push rod chamber and the crank chamber communicate with each other through an oil chamber and an oil discharge port. Oil mist generated in the crank chamber flows into the rocker chamber through the oil delivery passage, as the oil discharge port begins to resist the flow. The mist flows into the push rod chamber after the mist is made into liquid for lubrication of parts to be lubricated. Thus, the oil is returned to the crank chamber from the oil delivery passage through the rocker chamber, the push rod chamber, and the oil chamber to form a circulating path. Accordingly, a larger quantity of oil than the required quantity is not stored in the rocker chamber, and a preferable amount of gas-liquid separation may be obtained even when effects caused by vigorous vertical vibration of a vibrator make the oil stored in the rocker chamber strongly shake.
