Abstract:
A POWER BRAKE SYSTEM AND SERVOMOTOR WHEREIN A SKID SENSING MEANS IS ADAPTED TO AUTOMATICALLY TAKE OVER CONTROL OF THE SERVOMOTOR FROM THE VEHICLE OPERATOR TO MODULATE BRAKING AT ITS MAXIMUM EFFECTIVENESS, AND WHICH IS FURTHER IMPROVED BY BRAKE PRESSURE PROPORTIONING MEANS TO ACCOMMODATE VEHICLE WEIGHT SHIFTING DURING DECELERATION.
Abstract:
A hydraulic brake booster is disclosed which provides a power assist to the vehicle operator during a brake application. Pressurized hydraulic fluid is supplied to the booster from the vehicle''s power steering pump which also supplies pressurized fluid for charging an accumulator. During normal operation of the system, fluid is supplied directly from the pump to the booster. However, if a malfunction interrupts the supply of pressurized fluid from the pump, the booster can use the fluid stored in the accumulator to apply the vehicle''s brakes.
Abstract:
A means to regulate hydraulic system pressure based upon a function of the work produced by one set of actuators and having a device to monitor the pressure from said means to another set of actuators as a function of the comparison of their work required with the work done by the one set of actuators.
