Title:
カム軸伝動装置、殊にディーゼル燃料噴射ポンプ用のカム軸伝動装置
Document Type and Number:
Japanese Patent JP2010503803
Kind Code:
A
Abstract:
The invention provides for operation of camshafts, particularly for an injection pump for diesel. A camshaft rotates around a longitudinal axis of a camshaft. The camshaft has at least one cam being in cooperation with a pressure roller driven in a lifting manner. The pressure roller rotates on the peripheral surface of the cam. The upward stroke of the pressure roller is a working stroke during which the pressure roller moves away from the longitudinal axis of the camshaft. During a return stroke the pressure roller moves toward the longitudinal axis of the camshaft. The peripheral surface of the cam has a return stroke section and a working stroke section. The peripheral surface of the return stoke section has a greater friction value than the working stroke section. Thus an operation of camshafts for an injection pump for diesel is provided, securing a rotation of the pressure roller around the circumference of the cam within the whole speed range of the camshaft.
