1. A linear motion guide apparatus comprising:
a guide rail, a slider slidably attached onto said guide rail for moving along said guide rail, an end cap including a first side attached to and engaged with said slider and said end cap including a second side faced away from said slider, said end cap including a channel formed therein and defined between two legs for slidably receiving and engaging with said guide rail, and said end cap including an inlet formed in said end cap for receiving a lubricating fluid, and said end cap including two chambers formed in said legs and located in said first side of said end cap respectively, and said end cap including a passage formed in said first side of said end cap and communicating with said chambers of said end cap, and said end cap including a guiding pathway formed in said first side of said end cap and communicating with said inlet of said end cap for receiving the lubricating fluid from said inlet of said end cap, and said guiding pathway being communicating with said passage of said end cap for separating said passage of said end cap into a first passageway and a second passageway which are communicating with said chambers of said legs of said end cap respectively, and a follower slidably received and engaged in said guiding pathway of said end cap and movable toward either said first passageway or said second passageway of said passage of said end cap for partially blocking either said first passageway or said second passageway of said end cap and for limiting a flowing speed of said lubricating fluid from said guiding pathway to either said first passageway or said second passageway of said end cap, and said follower including an outer diameter (D) greater than that of said first and said second passageways of said passage of said end cap for preventing said follower from being engaged into said passage of said end cap, and for limiting said follower to slide within said guiding pathway of said end cap. |
