Abstract: The anti-roll bar 7 supported by two bearings 9 and connected at each of its ends to a suspension lever 4, is maintained in its axial direction by at least one tie 10. The latter is resiliently deformable in torsion and secured to the bar at 11 and to the structure of the vehicle at 12. This immobilization of the bar is achieved by cheap devices which introduce no friction producing noise or wear. Application in motor vehicles.

Abstract: Each overhead cam-shaft 4, 5 of the engine is journalled in bearings 6, 7, one half of which is formed in the cylinder head 2, while the other half is formed in common caps 8 bolted to the cylinder head. Provided between each cam-shaft and the central fixing bolt 17 of the caps are apertures 18 providing access to the bolts 3 fixing the cylinder head to the cylinder block 1. There is obtained in this way a more compact engine in which the valves 10, 12 are not inclined to an exaggerated extent.

Abstract: A pressure regulator for a pump aspirating a working fluid from a tank comprises a throttle valve at a junction between an inlet pipe extending from the tank and an outlet pipe terminating at the intake port of the pump. The discharge port of the pump is connected to a control port of the regulator housing in line with the inlet pipe, this control port being separated by a partition with a narrow passage from a chamber containing the shiftable valve body. The passage accommodates a small-diameter rod which has a flat tail penetrating that passage only when the discharge pressure of the pump has reached a certain threshold above a point at which that pressure has caused the rod to move the valve body into a blocking position against a countervailing spring pressure. This establishes a connection between the discharge and intake ports of the pump preventing further rises in the pump's delivery pressure.

Abstract: A retainer for the parts of the interior assembly of sliding automotive universal joints, for example, of the tripod type constituted, of a splined hub with trunnions which support rollers with interposed bearing means, such as needle bearings. The retainer (1) is a flat slitted ring (2) made of a slightly elastically deformable material and has regularly spaced open seats (L) for receiving rollers (12), and holder (6,7) to retain the rollers (12) and needle bearings (13) in position on the trunnions (11) of the interior assembly of the universal joint.
