摘要： A flow-control passive valve controls flow of fluid between an upstream space at high pressure and downstream space at low pressure. The valve comprises a valve body in fluid communication with the upstream and downstream spaces and within which are defined first and second spaces. A movable member is slidably received in a body chamber, and a force is applied to the member tending to keep it in a given “non-working” position. Metering discs meter the flow from the upstream to downstream space through the body and comprise first, second, and third fixed restrictors and first and second variable restrictors. Pressure in the first space is lower than that in the upstream space via a pressure drop through the first fixed restrictor while pressure in the second space is variable between the pressure in the first space and that in the downstream space depending on the position of the member.

摘要： The outer ring (3) of a motor-vehicle wheel-hub bearing (1) is housed in a cylindrical seat (9) of a strut (10) and is locked axially, on one side of the strut (10), by means of a radially inwardly-projecting rim (18) formed by cold deformation of a tubular portion (17) of the seat (9) and, on the other side, by means of a shoulder (11). A resiliently compressible ring (19) is inserted into the seat (9) of the strut (10) so as to be compressed axially between a lateral surface (12, 13) of the outer ring (3) of the bearing and the shoulder (11) or the deformed rim (18) of the seat (9), respectively, to compensate for any relative thermal expansion between the bearing and the seat.

摘要： The actuator comprises a cylinder and a rod. The cylinder comprises an inner cylindrical tube and an outer cylindrical tube which extend coaxially to each other along a longitudinal axis (z). The inner cylindrical tube accommodates a plunger which is rigidly connected to the rod and separates an inner volume of the inner cylindrical tube into a compression chamber and an extension chamber, wherein at least the compression chamber contains oil. The inner cylindrical tube and the outer cylindrical tube enclose with each other a reservoir chamber which is permanently in fluid communication with the extension chamber via at least one first passage provided in the inner cylindrical tube and contains a pressurized gas in a first portion thereof and oil in a remaining portion thereof. The cylinder further comprises an intermediate cylindrical tube which extends along the longitudinal axis (z) between the inner cylindrical tube and the outer cylindrical tube and encloses, along with the inner cylindrical tube, an intermediate chamber permanently in fluid communication with the compression chamber via at least one second passage provided in the inner cylindrical tube. The actuator further comprises a check valve associated to the inner cylindrical tube to allow the oil to flow in the direction from the reservoir chamber to the compression chamber only, and an electrically-operated flow control valve which is associated to the intermediate cylindrical tube for controlling the flow of the oil between the intermediate chamber and the reservoir chamber. The flow control valve is movable between a first operating position, in which it allows the oil to flow between the intermediate chamber and the reservoir chamber, and a second operating position, in which it prevents the oil from flowing between the intermediate chamber and the reservoir chamber.

摘要： An apparatus and a method for managing the energy supplied to a low-voltage system of a motor vehicle that comprises an energy-recovery stage. The low-voltage system, operating at a first voltage, comprises a battery, a system for charging the battery, and motor-vehicle loads supplied by the battery and/or by the alternator. A high-voltage system operates at a second voltage higher than the first voltage. The high-voltage system includes the vehicle energy-recovery stage, which supplies the second voltage. The second voltage is supplied through an intermediate energy-storage system and a DC-DC converter, which converts the second voltage into the first voltage on the low-voltage bus. A module regulates the alternator, that activates at least one first operating mode in which the alternator regulates a voltage of the battery at a nominal operating value.

摘要： The damper and spring unit comprises a damper, a spring member extending coaxially to the damper, a bottom spring plate and a vehicle height adjustment device for adjusting the height of the vehicle from the ground. A first damper element is connected to a wheel carrier of the suspension and a second damper element is slidable relative to the first damper element along the longitudinal axis (z). The adjustment device is interposed between the first damper element and the spring member to change the linear position of the bottom spring plate, and a bottom end of the spring member, relative to the first damper element. A hydraulic linear actuator comprising a cylinder is secured to the first damper element and a piston drivingly connected for translation with the bottom spring plate along the longitudinal axis (z) of the damper between a bottom end-of-travel position and a top end-of-travel position.

摘要： A damper with a cylinder and a rod, a spring arranged around the damper and a linear actuator arranged to change in a controlled manner the axial position of a bottom end of the spring relative to the cylinder of the damper. The actuator comprises an inner cylindrical element arranged to be mounted around the cylinder of the damper, an outer cylindrical element, which is mounted so as to be axially slidable relative to the inner cylindrical element and is arranged to support the bottom end of the spring, and a working chamber arranged to be filled with a fluid under pressure to adjust the axial position of the outer cylindrical element relative to the inner cylindrical element. The working chamber is delimited, both radially and axially, only by the inner cylindrical element and by the outer cylindrical element. The outer cylindrical element is provided with a support flange arranged to support the bottom end of the spring.
