Abstract
A combined master cylinder and dump valve includes a piston slideable within a body bore that defines a master cylinder for pressurizing a brake port. The piston includes a piston seal for isolating a pressure port from a tank port, a piston bore, a first piston hole set for hydraulically connecting the pressure port to the piston bore and a second piston hole set for hydraulically connecting the piston bore to the tank port. A plunger slideably received in the piston bore has a plunger hole set for selectively connecting the first piston hole set with a plunger bore, and a plunger seal arrangement for selectively isolating the first piston hole set from the plunger bore. The plunger bore is hydraulically connected to the piston bore.
