Title:
COMPRESSION RATIO CONTROLLER FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
Japanese Patent JP2688728
Kind Code:
B2
Abstract:
PURPOSE: To drive a stopper pin with a hydraulic pump whose discharging ability is small with the durability of a connecting rod ensured, by forming only one oil passage in the connecting rod.
CONSTITUTION: This controller is provided with an eccentric sleeve 16 which is rotatably-fitted onto a crank pin 12, and a stopper pin 19 which is engaged with either of a pair of engaging part 16a or 16b which are assembled in a connecting rod 13 relatively rotatably-fitted into the eccentric sleeve 16 and are formed facing the eccentric sleeve 16 to switch a relatively rotating position of the connecting rod 13 and the eccentric sleeve 16. This controller is also provided with a spring member 25 which energizes the stopper pin 19 to one side of the engaging parts, a pressure oil supply means 23, 29 which supplies pressure oil for energizing the stopper pin 19 to the other side of the engaging parts against the spring force of the spring member 25, and a lubricating oil supply means 32 supplies lubricating oil into a clearance between the eccentric sleeve 16 and the crank pin 12.
