Device for producing brake pedal resistance in response to low pressure of brake pedal by driver, comprises variable throttle mechanism, which is coupled with operating fluid supplied execution

摘要

The device comprises a brake pedal resistance, which is produced in response to a low pressure of a brake pedal. A variable throttle mechanism (100) is coupled with an operating fluid supplied execution. An operating fluid is supplied from a master cylinder (32). A stroke simulator (69) communicates with the variable throttle mechanism, to modify a fluid inlet area, if a flow rate of the master cylinder exceeds a predetermined flow rate of the operating fluid supplied.
