ABSTRACT:
A flow control apparatus for a brake master cylinder of a vehicle includes a valve chamber formed within a plug threadably secured to an outlet port of the master cylinder which is fluidically connected to the wheel cylinders of the vehicle, a flow control valve movably disposed within the valve chamber having projecting portions on one face of a flat portion thereof for providing a gap between the valve chamber wall and the valve in one end position of movement of the valve and a flow passage through the flat portion, a spring retainer secured within the inner end of the plug having a central opening for slidably receiving a central extension of the other face of the valve flat portion and a plurality of flow passages therethrough, and a compression spring between the other face of the valve portion and the spring retainer for normally maintaining the valve against the valve chamber wall with the projecting portions abutting thereagainst, whereby brake pedal depression and release alters the quantity of fluid flowing between the master cylinder and the wheel cylinders.
