Abstract

A hydraulic brake booster (10) includes a spring-balanced control valve (42) communicating pressurized fluid to a pressure chamber (14) in response to an operator input. The magnitude of the fluid pressure communicated to the pressure chamber (14) is a function of the balance of spring forces applied to the control valve (42) by a pair of opposed springs (50, 82). An adjustable assembly (92) engages one of the opposed springs (50, 82) so that the balance of spring forces applied to the control valve (42) may be adjusted to limit to a safe level the maximum fluid pressure communicable to the pressure chamber (14). The adjustable assembly (92) includes a pair of relatively-rotatable members (106, 108) which each define oblique cam surfaces (122, 124) engaging the other member. One of the members (106) engages one of the opposed springs (50, 82). The other member (108) includes an elongate stem (118) terminating in an end (120) external of the booster housing (12).
