Abstract

See full text

A single valve compression release bridge brake is provided. The single valve compression release bridge brake includes a braking piston (160) integrated into an inner end of a valve bridge (400) which is located under a rocker arm (210) of an engine. The braking piston (160) is slidably disposed in a braking piston bore (190) opened downwards from the inner end of the valve bridge (400). The lower end of the braking piston (160) is connected to the inner exhaust valve (3001). Oil is supplied to the braking piston bore (190) in the valve bridge (400). The inner end of the valve bridge (400) above the braking piston (160) is pushed upwards against the rocker arm (210) by oil pressure, and a hydraulic linkage is formed between the braking piston (160) and the valve bridge (400). A braking cam lobe (232,233) actuates the rocker arm (210), the inner end of the valve bridge (400), the hydraulic linkage, the braking piston (160), and finally the inner exhaust valve (3001) for the single valve compression release bridge brake.
