Abstract
This invention relates to a housing for receiving a reaction disk in a pneumatic servomotor. The housing and reaction disk co-operate to resist too fast a forward travel of a piston when the brake is actuated and thereby avoid an undesired reopening of a passage connecting a front chamber with a rear chamber in a brake booster during a brake application. The reaction disk ( ) is located in an inner space of the housing ( ) that has a greater size than the volume of the disk ( ). The disk ( ) is initially deformed to completely fill the housing ( ) by an input force corresponding to a desired brake application to limit the forward speed of the pneumatic piston and only thereafter as a reaction force develops during the brake application, does the reaction force balance the input force applied to the disk ( ) during a brake application.
