Pressure equalization in a proportionally regulated fluid system |
摘要 |
A braking system generally provides pressure equalization between the sides of a split braking circuit. The amount of equalization provided is limited to enable the introduction of purposely induced pressure variances. A result is that unintentional pressure variations are moderated and intentional target pressure variations are easily obtainable. The braking system provides power braking operation in response to a manually actuated master cylinder. Fluid pressure is transmitted through isolation valves directly to the wheel brakes. The braking system also provides power operation in response to a powered pump. The pump delivers pressurized fluid through a controllable supply valve. When the supply valve is open, the isolation valve(s) are shifted to provide open fluid communication path between proportional pressure control valves and the wheel brakes. The pressure equalization effecting device is isolated from the master cylinder pressurized circuit during base brake operation.
