摘要:
An arrangement for the control of the oil feed into a control chamber of a piston with variable compression height for internal-combustion engines comprises a control valve in the longitudinal bore of a connecting rod that is provided with a flow-through bore for the oil supply of the control chamber in the operation of the internal-combustion engine. This flow-through bore is closed as a function of the inertial forces acting in the oil feed. In order to avoid a ceasing of the oil column in the longitudinal bore, the control valve has an additional control bore that is opened only in the starting phase and via which an additional amount of oil is guided from the lubricating oil circuit of the internal-combustion engine into the control chamber, which accelerates the upward control of the piston.
