摘要： A pneumatic brake booster (10) having a moving piston (22) for urging an actuating rod (34) of a master cylinder (28) in response to actuation of a plunger (56). The plunger has a front end that passes through the piston (22) that forms a first feeler (62) that penetrates a reaction disc (44) located between the piston (22) and the actuating rod (34) to transmit to the plunger (56) a reaction force of the master cylinder (28) and a second feeler (68) that is pushed by the plunger (56) when the control rod (46) is actuated at a rate higher than a determined rate and immobilized by a one-way engagement device (70) in an axial position that varies with respect to the piston (22) and then is driven by the piston to push the second feeler (68) into the disc (44) so that the first feeler (52) applies a braking force more rapidly.

摘要： A reaction device wherein a ratio of input force to output force for a brake booster is sequentially changed during a brake application. An actuation force derived from a pressure differential acts on a movable wall and is communicated through a cage as an output force to an push rod. The output force is a functional ratio of the input force as modified by a reaction disc and elastic means during a brake application. The reaction device functions as a rigid member until the input force reaches a first predetermined level Fd and a first boost ratio is in effect until a second predetermined force Fe is reached and a second boost ratio is in effect until a third predetermined input force level Ff is reached and a third boost ratio is in effect until a fourth predetermined fource level is reached.
