Title:
METHOD FOR CONTAINING OIL OUTSIDE CRANK CHAMBER FOR ENGINE LUBRICATOR AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JPH05133213
Kind Code:
A
Abstract:
PURPOSE:To miniaturize an engine and maintain an oil level in a stable height by allowing oil staying inside an oil receiving chamber inside a crank chamber to flow into an oil containing chamber outside the crank chamber through a communication portion between the chambers in such a manner as to push it up by the use of a pressure of blow-by gas inside the crank chamber. CONSTITUTION:An oil receiving chamber 52 inside a crank chamber 51 of an engine E is disposed in the lower portion inside the crank chamber 51. An oil containing chamber 58 outside the crank chamber is provided outside the crank chamber 51. The oil receiving chamber 52 inside the crank chamber is communicated with the oil containing chamber 58 outside the crank chamber via a communicating portion 61 between the chambers. An oil feeder P between the chambers utilizes a pressure Pb of a blow-by gas BG which is generated inside the crank chamber 51 in operation of the engine E. The pressure Pb of blow-by gas inside the crank chamber 51 allows oil staying inside the oil receiving chamber 52 inside the crank chamber to flow into the oil containing chamber 58 outside the crank chamber through a communicating path 61 between the chambers in such a manner as to push it up.
