Abstract: A vehicle brake booster includes a brake input member configured to receive a braking input force and a booster housing divided into a first chamber adjacent the brake input member and a second chamber remote from the brake input member. A poppet valve includes a poppet valve body and a poppet seal, the poppet valve operable to maintain separation between pressure and vacuum during assisted braking and further being operable to enable evacuation of the air from the first chamber through one or more side ports of the poppet valve body upon release of the braking input force and completion of the assisted braking A restrictor element provides a predetermined release speed for the booster. The one or more side ports define a total flow resistance of the poppet valve body which is less than an effective total flow resistance of the poppet valve body set by the restrictor element.

Abstract: The present invention provides a vacuum booster, which is constructed such that an area with which a cylinder communicates with a port communicating with a reservoir and being open to the cylinder is reduced at high temperature, so that a sufficient reaction force can be transmitted from a piston of a master cylinder to a valve mechanism at an initial stage of the braking operation, thus preventing vibration or noise from being generated in the valve mechanism. At high temperature, stop position, at which backward movement of the piston of the master cylinder is limited by an output member while a valve piston is at a non-operating position, is shifted forwards by a stop position shifting means, thus reducing the area with which the cylinder communicates with the port communicating with the reservoir and being open to the cylinder. At low temperature, while the valve piston is at the non-operating position, the stop position of the piston is not shifted, thus maintaining the area wide, with which the port communicates with the cylinder.

Abstract: A braking device and a method of manufacture of such a braking device. The braking device has a booster (1) formed of a cover (12) and of a cylinder (10). A central orifice (8) is formed on the cylinder. A master cylinder (5) has a body (14) that partially enters the booster via the central orifice. The master cylinder is fixed to the cylinder of the booster by plastic deformation of a hollow shaft (9). The hollow shaft borders the central orifice and extends towards the outside of the envelope and penetrates at least one orifice made in an exterior surface of the body of the master cylinder. The cylinder has a flat face that surrounds the central orifice such that a flange (6) extends radially towards the outside of the body of the master cylinder and bears more or less flat against the flat face of the cylinder.

Abstract: A negative pressure type brake hydraulic pressure generating device is proposed in which the stroke on the operating side can be set independently of the stroke on the output side. A slide resistance imparting means is provided between the fixed shell and a piston having a built-in control valve introducing atmospheric air to cancel the slide resistance which is the cause of increased stroke hysteresis of the piston, i.e. the slide resistance applied to the piston at airtight seal portions between the power plate and the piston.

Abstract: In order to improve the deformation behavior of a vacuum brake booster provided with force transmission pins that are used to transmit forces onto a body splashboard of a motor vehicle, the invention discloses that the force transmission pins are made up of two sections having different strength. To achieve a sufficiently low strength when a fastening screw is used for a first section, the first section is embodied as a hollow body, and the fastening screw extends only over the length of a second section of the pin. Because the first section is configured as a hollow body, the screw arranged in the second section can be actuated through the first section.
