The invention relates to a vacuum brake booster, comprising a vacuum chamber, a working chamber which is separated from the vacuum chamber by a movable wall, and a control valve.
The vacuum chamber (3) can be connected to a vacuum source (12).
The invention relates to a vacuum brake booster (10) comprising a vacuum chamber (16), a moveable wall (14), a working chamber (18) and a control valve.
Also disposed in the vacuum chamber is a fixed arm.
The invention relates to a method for determining the pressure present in the vacuum chamber of a brake booster vacuum (BBV).
The invention also relates to a low-pressure chamber for processing fluids, which is equipped with a heating plate with holes for heating areas of the interior space of the low-pressure chamber.
The guide disks thereby respond to a pressure differential between the vacuum plenum and the air supply chamber to actuate the valve.
At the end of the annular piston facing away from the pressure chamber, the annular piston actuates a release bearing arranged there.
The vacuum cleaner described has a container (2) containing liquid and connected to a low-pressure chamber (4) in which an underpressure is generated by means of a fan unit (6).
According to the invention, the brake servo unit has at least one additional vacuum negative-pressure chamber (17) which can be connected to the pressure chamber, using a shifting device (18).
The control valve (18) can be controlled mechanically by the actuation of the pedal to obtain a pressure differential that determines the actuating force between the working chamber (42) and the negative pressure chamber (40).
A vacuum detector (17) for a motor vehicle brake booster vacuum chamber comprises a membrane (11) that is deformable under the effect of pressure variations in the chamber.
Vacuum sensor for brake booster and associated control method.
A vacuum is created inside the suction chamber (8) in order to fix the component and the suction cup (5) to each other with retention force for a subsequent manipulation of the component.
The invention relates to a pneumatic brake booster (10) comprising a booster housing (12) whose interior is subdivided into a low-pressure chamber (16) and a working chamber (18) by at least one moveable wall (14).
The invention is characterised in that the sealing protuberance (7) comprises elements, which enable a reduction in pressure from the negative pressure chamber (3) to the working chamber (4) by means of the sealing protuberance (7).
This warning signal drives a control valve (12) which generates a pressure difference between the working chamber (9) and the vacuum chamber (10) in a brake booster (4) when the warning signal is generated.
The envelope feeder with a rotating vacuum-operated suction drum (3) is a further development of the envelope feeder with an underpressure chamber and perforated conveyor belt.
