摘要： A pneumatic brake booster for motor vehicles, comprises a booster housing, the interior of which is separated into a working chamber and a low-pressure chamber by an axially movable wall that can be supplied with a pneumatic differential pressure; a control housing; and a control valve which controls a differential pressure between the working chamber and the low-pressure chamber. The control valve controls an airflow between the working chamber and the low-pressure chamber or a surrounding atmosphere. The control valve has a plate valve and a valve piston, a seal region of which can be sealingly placed on the plate valve and which can be moved in a stroke direction R. A fine and low-noise metering of the brake force is achieved by providing a throttle point between the valve piston and the plate valve for throttling the airflow dependent on the stroke.

摘要： Provided is a negative pressure type booster device, in which a diaphragm of a movable partition wall has, in a penetration portion through which a tie rod bolt hermetically penetrates, a tubular guide portion that abuts against an annular flange portion provided on the tie rod bolt during forward movement of a power piston, and an annular sealing portion that is provided in the rear of the guide portion to block communication between a negative pressure chamber and a variable pressure chamber. The guide portion is provided with a communication portion through which a negative pressure chamber side space exposed by the front surface of the sealing portion communicates with the negative pressure chamber, even in a state in which the guide portion abuts against the annular flange portion.

摘要： The invention relates to a tandem pneumatic brake booster (1) for a vehicle. The objective is to prevent a blocking of a booster thrust rod (4) in the maximum travel position. The blocking appears following a sealed adhesion of a first plate skirt (12) on a seal (22) of the tandem booster. This seal blocks a vacuum in a first front chamber (5). To prevent this blocking, provision is made to crenelate a first lip (23) pressed against the pneumatic piston (3) of a seal. Merlons prevent a sealed adhesion of the plate skirt (12) over the whole seal (22). This absence of adhesion creates a leakage of air to the first front chamber (5) and allows a return to a rest position.

摘要： A pneumatic brake booster comprising an envelope of longitudinal axis formed of a dish having a rim and a lid. The envelope defines an interior volume that is divided into a variable-pressure work chamber and a low-pressure chamber by a skirt. The skirt is mounted to sealingly slide along the longitudinal axis of the envelope. The skirt has a central orifice with a pneumatic piston sealingly mounted therein. The sealing between the variable-pressure work chamber and the low-pressure chamber is achieved by a first sealing member arranged between a radially internal first end of the skid and a radially external end of the piston and a second sealing member arranged at a radially external second end of the skid and an internal surface of the rim. The skid provides sealing between the radially external first end of the skirt and the radially internal second end of the skirt.

摘要： A vacuum booster and method utilize a power piston apparatus including a power piston operatively mounted within a booster housing for movement along a longitudinal axis of the booster, and having a sliding seal fixedly attached thereto for slidingly engaging a sealing surface of an annular wall of the booster housing and axially dividing the closed booster cavity into a high pressure cavity and a low pressure cavity. The sliding seal is mounted on an outer periphery of a seal support flange extending radially outward from the power piston. A convoluted divider provides an air passage connecting primary and secondary high pressure cavities in the booster, without the use of air tubes.

摘要： A vacuum servo unit includes a movable power piston having a base portion and a cylindrical portion whose output side end portion is connected to the input side end portion of the base portion. The base portion has an annular first projection projecting into the inside of the cylindrical portion and a second projection projecting into the inside of the cylindrical portion. the second projection divides the space surrounded by the annular first projection into a first space and a second space. A vacuum path communicates the constant pressure chamber with the first space, and an air path communicates the variable pressure chamber with the second path. Thus, the area of the cross-section of the second space in a plane perpendicular to the axis of the movable power piston can be enlarged so that atmospheric air can smoothly flow into the variable pressure chamber.
