Abstract

Improvements in two-stroke piston combustion engines, with a spider and a rod or journal, surrounded by connecting rod bearings to which the lubricant reaches under lubrication pressure, from a lubrication pipe, characterized in that the lubrication pressure is higher than the minimum pressure that occurs during operation in the bearing and because a blocking element is mounted in the lubrication pipe that, in the area of the duty cycle in which the bearing pressure (BL), it is less than the lubrication pressure (PO), it allows to establish a communication between the lubrication pipe and the bearing support surfaces, while at high pressures of the bearings this communication is interrupted.
