    • The invention relates to a cold advance device for advancing the injection beginning in cold condition (- 25 °C to + 40 °C), in single and multi-cylinder diesel engine with single plunger pumps, by means of which the injection onset is adjusted in cold condition and also in normal condition and comprising of a piston (12) so provided in the roller tappet (10), such that it moves up and down the said roller tappet (10), due to flow of lubricating oil from lubricating oil supply pump , through a plate valve (14). Said lubricating oil which flows through the said plate valve (14), lifts the said hydro tappet piston (12) by 1,5 mm. . The said plate valve (14) is provided with a throttle hole (15).

    • An object of the invention is to provide a construction for a crank device for performing power conversion between a reciprocating linear motion and a rotary motion, which construction provides a good dynamic balance and power transmission efficiency and is suitable for high-speed operation. An outer diameter of a planetary gear (21) of a planetary mechanism (4) is set to half of an inner diameter of a stationary internal gear (20), and a crank pin (12) of a crank shaft (2) is rotatably supported by and connected to the center of rotation of the planetary gear (21). A connecting rod (3) is rotatably supported by and connected to the outer peripheral portion of the planetary gear (21). Accordingly, the connecting rod (3) effects linear motion in a direction of reciprocation of a piston (15) without shaking, so that a stable dynamic balance is ensured. Further, a mass distribution for respective constituent members is set so as to provide a dynamic balance between a reciprocating section and a rotating section whereby a uniform and stable movement is ensured from a region of low-speed rotation to a region of high-speed rotation.
    • 本发明的目的是提供一种用于在往复直线运动和旋转运动之间进行功率转换的曲柄装置的结构,该结构提供良好的动平衡和动力传递效率,并且适合于高速运行。 将行星机构(4)的行星齿轮(21)的外径设定为固定内齿轮(20)的内径的一半,曲轴(2)的曲柄销(12)可旋转 由行星齿轮(21)的旋转中心支撑并连接到行星齿轮(21)的旋转中心。 连杆(3)可旋转地支撑并与行星齿轮(21)的外周部连接。 因此,连杆(3)在没有晃动的情况下在活塞(15)的往复运动方向上进行直线运动,从而确保了稳定的动平衡。 此外,各构成构件的质量分布被设定为在往复运动部分和旋转部分之间提供动态平衡,从而从低速旋转区域到高速旋转区域确保均匀且稳定的运动 。
