Abstract
The invention discloses a valve rocker with an internal oil-filtering and sound-insulating washer. The valve rocker comprises a rocker body. A rocker shaft base is arranged in the center of the rocker body. Valve rocker bodies are arranged at the two ends of the rocker body respectively. A shaft hole is formed in the center of the rocker shaft base. The sound-insulating washer is further arranged between the shaft hole and the rocker shaft base. An oil filtering device is arranged in the sound-insulating washer. An oil outlet is formed in one end of the oil filtering device. An annular oil groove is formed in the sound-insulating washer. One end of the annular oil groove is connected to the oil outlet. An oil discharging port is formed in the other end of the annular oil groove. In this way, sound insulation treatment can be conducted on the valve rocker by filling the valve rocker with the sound-insulating washer, and the oil filtering device is installed in the sound-insulating washer and used for discharging lubricating oil, so that the situation that the valve rocker is abraded due to the shortage of lubricating oil is avoided, and the service life of the valve rocker is prolonged.
