    • PROBLEM TO BE SOLVED: To provide a simply and conveniently electrically driven reciprocating pump provided with two opposed pistons.SOLUTION: In the pump for liquid paint provided with first and second pistons (19, 21) capable of linear reciprocation operation in each of first and second cylinders (17, 18), the first and second pistons are moved for each piston by operation of an alternating current electric motor (13). A rotating output shaft of the alternating current electric motor is connected to the first and second pistons with means including a constant speed cam (31) and cam followers (32, 33) for converting rotation operation of the output shaft into mutually 180° phase deviated reciprocating operation of the first and second pistons.
    • 要解决的问题:提供一种简单方便的电动往复泵,其设置有两个相对的活塞。 解决方案:在具有能够在第一和第二气缸(17,18)中的每一个中进行线性往复运动的第一和第二活塞(19,21)的液体涂料的泵中,第一和第二活塞为每个活塞 通过交流电动机(13)的操作。 交流电动机的旋转输出轴与具有恒速凸轮(31)和凸轮从动件(32,33)的装置连接到第一和第二活塞,用于将输出轴的旋转操作转换成相位偏移180° 第一和第二活塞的往复运动。 版权所有(C)2012,JPO&INPIT
