Abstract: A method and apparatus are disclosed for selectively providing a fluid communication path between a plunger element and a contact region of an intermediate element that drives the plunger element. The fluid communication path is suitable for lubricant flow to enable a contact zone to occasionally be lubricated. The apparatus includes an elongate plunger element comprising a first end region, an intermediate element comprising a contact region arranged to selectively abut with and thereby urge a further end region of the plunger element and a spring seat member at the further end region of the plunger element. The spring seat member biases the further end region of the plunger element away from the intermediate element during a portion of a cycle of motion of the plunger element. A fluid communication path is thereby provided between an abutment surface of the further end region and the contact region.

Abstract translation: 公开了一种用于选择性地提供柱塞元件和驱动柱塞元件的中间元件的接触区域之间的流体连通路径的方法和装置。 流体连通路径适用于润滑剂流动，以使偶尔可以润滑接触区域。 该装置包括细长的柱塞元件，该柱塞元件包括第一端区域，中间元件，该中间元件包括接触区域，该接触区域布置成选择性地抵靠柱塞元件的另一端部区域并且从而推动柱塞元件的另一端部区域;以及弹簧座构件， 。 在柱塞元件的运动周期的一部分期间，弹簧座构件偏压柱塞元件的另一端部区域远离中间元件。 因此，在另一端部区域的邻接表面和接触区域之间提供流体连通路径。
