Abstract: A valve train for a reciprocating piston internal combustion engine with a transmission element in the form of a rocker arm (1) or pivot arm that can be actuated, on one hand, at least indirectly by a cam of a camshaft and is in active connection, on the other hand, through an intermediate connection of a valve bridge (4), with gas-exchange valves (7, 8). The valve bridge (4) has hydraulic valve lash compensation elements (“HVAs”) allocated to each gas-exchange valve (7, 8).

Abstract: 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.

Abstract: The present invention can achieve a variable valve mechanism having a simple and compact configuration. A variable valve mechanism changes an opening/closing timing of an intake valve or an exhaust valve in response to an engine rotation speed. The variable valve mechanism includes: a cam sprocket which rotates in response to a rotation of a crank shaft; an intake cam shaft which is integrated with an intake cam; an exhaust cam shaft which is integrated with an exhaust cam; and a governor flange that transmits a rotation of the cam sprocket to the intake cam shaft and the exhaust cam shaft. The intake cam shaft and the exhaust cam shaft are formed so that the other cam shaft is inserted through one cam shaft to be relatively rotatable. The governor flange is provided to rotate along with the intake cam shaft and rotates relative to the cam sprocket under a predetermined condition.
