Title: Lubricating oil feeding device for rotary piston engine
Inventor: TOMITA YOSHIAKI
IPC: F01C21/04
Filed: 1986-04-07
Abstract: PURPOSE:To prevent the improper quantity of the lubricating oil supplied into a casing in transient state by delaying the increase/decrease control for the directly supplied oil when the ratio between the oil supplied into a port and the directly supplied oil is varied. CONSTITUTION:A control unit 30 is equipped with an oil feed ratio control means 36 which controls the oil quantity discharged from each discharge port 27a, 27b of the metering oil pump 20 so that the oil feed ratio supplied from an oil feeding port 15 opened into an intake passage 12 and the second oil feeding port 16 opened into the inner peripheral surface 2a of a rotor housing 2 is controlled and varied according to the engine state, and a delay means 37 which delays the increase/decrease-control of the oil quantity (oil feed quan tity supplied from the second oil feeding port 16) discharged from the second discharge port 27 for a prescribed time. Therefore, also the variation of the lubricating oil feed quantity directly supplied from the second oil feeding port 16 is delayed in the degree corresponding to the delay of the variation of the lubricating oil feed quantity supplied from the first oil feeding port 15 through the intake passage 12.
