摘要： A mechanical lubricating pump for supplying lubricating oil to rotary parts of machines and equipment. A rotatable distributor is inserted in the lengthwise direction of a pump body, and a suction port and a discharge port are provided in the diametrical direction of the body. A worm gear is disposed at one end of the distributor, while a plunger is inserted at the other end. Upon rotation of the distributor, the plunger executes relative movements in the axial direction, so that the pumping action is effected to suck and discharge the lubricating oil. The distributor has means by which the roles of the suction port and the discharge port at the time of the forward rotation of a driving source are maintained as they are when the driving source is reversely rotated. As a result, even when the driving source is brought from the forward rotation to the reverse rotation, the pumping action is continued, the positional relation between suction and discharge passages remains unchanged, and the discharge of the lubricating oil is carried out uninterruptedly.
摘要翻译：机械润滑泵，用于将机油和设备的旋转部件供给润滑油。可旋转的分配器沿泵体的长度方向插入，并且在主体的直径方向设有吸入口和排出口。蜗杆设置在分配器的一端，同时在另一端插入柱塞。在分配器旋转时，柱塞在轴向上执行相对运动，从而进行泵送动作以吸入和排出润滑油。分配器具有这样的装置，当驱动源反向旋转时，驱动源正向旋转时吸入口和排出口的作用保持原样。结果，即使当驱动源从正向旋转到反向旋转时，泵送动作持续，吸入排出通路之间的位置关系保持不变，并且润滑油的排出不间断地进行。
