Publication number: 20170101903Abstract: A system for variable actuation of an engine valve of an internal-combustion engine includes a master piston and a slave piston, driven by the master piston. A control valve controls a communication of a volume of a pressurized fluid with a lower pressure environment, which is connected to a fluid accumulator, and an electronic control unit controls the electrically operated control valve. A device for dampening pressure oscillations is connected to the volume of pressurized fluid and includes an additional volume adapted for receiving fluid from the volume of pressurized fluid only when, following upon oscillations of the pressure in the volume of pressurized fluid, the pressure exceeds a maximum threshold value, which is higher than a mean pressure value that is set up in the volume of pressurized fluid when the master piston drives the slave piston in normal operating conditions.Type: ApplicationFiled: September 29, 2016Publication date: April 13, 2017Applicant: C.R.F.

Patent number: 9422016Abstract: A method for mounting side doors on motor-vehicle bodies involves detecting—by means of optoelectronic systems—a plurality of dimensions measured along coordinates X, Y, Z, on the body and on the door units, with the aid of the proper references, for qualifying the geometric conditions of the coupling between the doors and the cooperating door receiving seats. On the basis of the detected dimensions, the method determines the mounting positions of each pair of hinge elements to be secured to the body and to the doors for accurate fit. The method involves mounting the hinge elements on the body in the determined positions, and mounting the doors on the body by connecting the body hinge elements and the door hinge elements to each other by simultaneously inserting articulation pins in seats, without requiring further operations for adjusting and recording geometrical settings.Type: GrantFiled: October 18, 2011Date of Patent: August 23, 2016Assignees: C.R.F.
