An hydraulic brake booster for an automobile hydraulic system comprising of a boost cylinder, a boost piston and a boost chamber defined by a boost piston working in a bore in a body and being adapted to apply an output force to an output rod in response to a pressure applied to a boost chamber under a control valve, in turn responsive to an input force from input rod, wherein the input rod move in a forward operating direction up to a prescribed point so as to prevent fluid from a radial high pressure supply port from entering the boost chamber when the booster is in an inoperative position, any added movement of the input rod in a forward operating direction lifts the boost piston ball and uncovers the supply port so as to allow pressurized fluid into the boost chamber from the accumulator.
An hydraulic brake booster for a automobile hydraulic system comprising of a boost cylinder, a boost piston and a boost chamber defined by a boost piston working in a bore in a body, the boost piston being adapted to apply an output force to an output rod in response to a pressure applied to a boost chamber under the control of a control valve, in turn responsive to an input force from input rod, characterized in that movement of the input rod in a forward operating direction upto a prescribed point so as to prevent fluid from a radial high pressure supply port from entering the boost chamber at least when the booster is in an inoperative position, any added movement of the input rod in a forward operating direction lifts the boost piston ball and uncovers the supply port so as to allow pressurized fluid into the boost chamber from the accumulator.
