Hydraulic braking system including power-operated pressure source device

Braking system including a power-operated hydraulic pressure source (12) operable to deliver a pressurized working fluid, a brake including a hydraulically operated brake cylinder (44, 48), and a flow-rate changing device (88, 90, 92, 150; 240, 242, 150; 340, 342, 344, 150; 436, 438, 440, 342, 150; 436, 438, 440, 150) disposed between the power-operated hydraulic pressure source and the brake cylinder and operable to change a rate of flow of the pressurized working fluid into the brake cylinder, which rate corresponds to a given rate at which the pressurized working fluid is delivered from the power-operated hydraulic pressure source
