Abstract
Disclosed is an integrated isolation/modulation valve for use in an anti-lock brake system which incorporates a spool valve element and a solenoid actuated valve. The solenoid actuated valve responds to control signals from an anti-lock brake system, the valve being normally closed and operable to an open position to produce a differential pressure across the spool valve. Movement of the spool valve in response to the differential pressure interrupts fluid communication between the brake system's master cylinder and wheel cylinders and simultaneously connects the wheel cylinder to the system's pressurized fluid source through an orifice which effects controlled building of brake pressure.
