| 主权项 | 1. A lubrication device of a high pressure pump for a common rail system, comprising: a first lubrication channel fluid-connecting a shaft chamber formed in a pump housing of the high pressure pump and a low pressure pump; and a support lubrication channel formed through a shoe such that a first end of the support lubrication channel is fluid-connected to the first lubrication channel and a second end of the support lubrication channel is disposed onto a friction portion where a cylindrical surface of a roller and the shoe contact each other, wherein the support lubrication channel includes: a first support channel branching off from the first lubrication channel and extending inside of the shoe substantially parallel with a longitudinal direction of the shoe; anda second support channel branching from and fluid-connected to the first support channel and formed in the shoe and extending substantially perpendicularly from the first support channel to be connected to the second end of the support lubrication channel. | ||
