摘要:
A fluid pressure-modulation device intended to be interposed between a hydraulic control and a corresponding receiver, comprising a first chamber connected to the control and a second chamber connected to the receiver, the chambers communicating with each other through a first passage controlled by a regulating valve and also through a second passage controlled by a normally-open isolating valve, the regulating valve being normally closed and the second passage controlled by the isolating valve being formed axially in the regulating valve. The regulating and isolating valves are assembled together to form conjointly a valve unit which is movably mounted in the first chamber, the isolating valve being fitted into a bore formed in the regulating valve. The device is especially applicable to the braking circuits of automobile vehicles in order to prevent locking of the vehicle wheels during braking.

A safety-belt buckle comprising first and second parts adapted to slide relative to one another. The first part called a catch casing includes an opening for receiving the nose of a latch in the closed position of the buckle. The second part includes a socalled latch support plate on which thh latch is pivotally mounted. A lever is provided for the actuation of the buckle and is pivotally connected to the latch against the action of spring carried by the latch support plate and urging the latch to its closed position. The lever has a pivot formed by an edge disposed between its mounting on the latch and its free end, the buckle being therefore capable of being opened by upward, downward or translatory movement of the actuating lever.
摘要:
A continuous power transmission device provided between a movement take-off and a receiving shaft, especially for automobile vehicles, comprising a reversible continuous speedvarying device and a planetary train with four elements, in which two elements of said train are continuously active, one of said elements being coupled to the movement take-off through the intermediary of said reversible continuous speed-varying device and the other element being coupled to said shaft, each of the two remaining elements, known as change-over elements being adapted to be rendered active or passive, and further comprising means for rendering one of said change-over elements active while the other element is passive, and vice versa.
