  • Patent number: 4484509
    Abstract: In vacuum brake boosters for motor vehicles, the vacuum casing is conventionally made of sheet steel. The vacuum casing is subjected to mechanical and pneumatic forces which have to be absorbed by the casing components. This makes it necessary to construct the casing components so they are strong enough to take these forces. The result of such construction is, however, high costs and high weight. To eliminate these disadvantages, the invention provides a brake booster wherein the vacuum casing includes a pipe therein extending in approximately coaxial of the longitudinal axis of the vacuum casing and connected to the transverse end walls of the vacuum casing, the pipe enclosing the master cylinder push rod, and the movable wall of the brake booster is sealed relative to the pipe and slidable thereon.

  • Patent number: 4480214
    Abstract: A starting circuit which is connected in parallel with the lamp. No ballast is required for the starting circuit. The starting circuit uses a pulse transformer, the primary of which is connected into an RC network, the secondary of which is connected in series with a capacitor which prevents current flow at the low frequency open circuit voltage. The circuit being in parallel with the lamp enables the use of low power components such as the pulse transformer, since the lamp operating current does not traverse the circuit as would be the case with a series starting circuit or ballast transformer.

  • Patent number: 4477125
    Abstract: Hydraulic brake systems are known which comprise antiskid control valves and a pressure fluid source where pressure fluid is fed via a valve device and an antiskid control valve to a wheel brake cylinder. The pressure fluid source includes two jointly driven pumps. The disadvantage of such a system is the constant presence of a high pump output although this high output is only rarely required. Therefore, according to the present invention, an energy saving is realized by having the suction connection of a first of two jointly driven pumps connected to a pressure fluid reservoir and the suction connection of a second of two jointly driven pumps connected to the pressure fluid outlet of an antiskid control valve.
