Patent attributes
A hydraulic lash compensation device for an engine includes a plunger assembly slidingly received within a body bore to define a high pressure chamber. The plunger assembly includes a lower pressure chamber, an upper plunger element, and a lower plunger element. A mechanical lift loss feature includes a generally annular lift stop member retained to the upper plunger element by an adjustment member that extends through the lift stop member and is adjustably received in upper plunger element. The lift stop member is biased away from upper plunger element by a spring. When the upper plunger element is received into the body, the upper plunger element is offset a predetermined distance from the lower plunger element by virtue of the lift stop member's engagement with the lower plunger element. The offset is adjustable based on the position of the lift stop member relative to the upper plunger element.
