1. A vacuum brake booster system comprising a vacuum brake booster (1) for providing vacuum power assist for a brake system, including a suction compensation pump (8) connected with the vacuum brake booster (1), the suction compensation pump (8) is so linked to a vacuum control valve (9...
Vacuum brake booster (10) with– a booster housing (12), whose interior space through at least one movable wall (14) into a vacuum chamber (16) and a working chamber (18) is divided, and– a control valve assembly (20) for controlling a on the movable wall (14) acting pressure diffe...
摘要: An apparatus for sensing the available vacuum in a power braking system having the ability to generate an additional source of vacuum which can be combined with the vacuum in the system to maintain the vacuum in the system within a predetermined range....
The invention relates to a vacuum brake-booster of the tandem type comprising two compartments (22, 24) separated by a stationary plate (20), each of the compartments being divided into a front chamber and a rear chamber by way of a piston (26, 28) and of an isolating diaphragm, at le...
In order to avoid the braking noise which occurs, when a tandem vacuum-brakebraking-force booster is actuated, due to the contact between the reset spring ... H Claudia,W Wilfried,G Kai-Michael 被引量: 0发表: 1997年 Hydraulic brake booster integrated with tandem master cylinder It has been...
The present invention refers to a vacuum retention valve in brake booster devices of automotive vehicles, comprising a first outlet (1) associa ted to the engine and a second outlet (2) associated to the brake booster device, a membrane (6) located in a chamber (7), and a flow path (...
The symptoms illustrated were of those previously mentioned except it included an inspection of additional components. When performing a vacuum source test, if low vacuum is present and determined to be the fault, the technician should inspect the vacuum line to the brake booster and the booster ...
The Booster No matter if the booster gets vacuum from the engine or a pump, if it is damaged, the brake pedal performance will change. The condition of the diaphragm inside the booster is also important. If it’s cracked, ruptured or leaking, it won’t hold vacuum and can’t provide ...
How to manipulate the device and the vacuum brake booster In addition the control unit, is calculated based on the pressure only to dominate (3) within the vacuum chamber, the saturation point vacuum control booster (1). In order to support the monitoring of the whole system, the present.....
PURPOSE: A vacuum generating device of a brake servo system is provided to brake a vehicle at sudden acceleration by generating negative pressure sufficiently despite suddenly increasing RPM(Revolutions Per Minute) of an engine at initial start of the engine. CONSTITUTION: Negative pressure is generate...
