摘要：
A reciprocating pump for pumping a fluid, especially for pumping a fluid such as UV ink which is subject to solidification when exposed to frictional forces. The pump has an internal displacement chamber with an inlet, and outlet, and a plunger which is reciprocally movable in the chamber. The plunger reciprocates through an axial passage in the housing at one end of the chamber, the passage being sized to receive the plunger with a clearance fit. First and second seals are positioned in the axial passage. Each seal is annular in shape and extends between the plunger and housing in sealing contact therewith. The pump housing is free from a bearing which contacts the plunger or guides its motion, such that the sealing contacts between the plunger and seals are the only contacts of the plunger in the housing.
摘要（中）：
用于泵送流体的往复泵，特别是用于泵送诸如UV暴露于摩擦力时固化的流体的UV油墨。 该泵具有一个具有入口和出口的内部移动室，以及可在该室中往复移动的柱塞。 柱塞在腔室的一端通过壳体中的轴向通道往复运动，该通道的大小适于以间隙配合接纳柱塞。 第一和第二密封件定位在轴向通道中。 每个密封件是环形的并且在柱塞和壳体之间在与其密封接触的位置上延伸。 泵壳体没有接触柱塞或引导其运动的轴承，使得柱塞和密封件之间的密封接触是壳体中柱塞的唯一接触。
