Abstract:
1. A hydraulic lash adjusting device for a plurality of identically operating gas exchange valves per cylinder of a valve train of an internal combustion engine, said device comprising a common housing in which pressure pistons corresponding in number to the identically operating gas exchange valves are arranged in close proximity to one another, each of said pressure pistons extending in a separate guide of the housing for relative axial displacement thereto and possessing on a housing-distal end, a support for an at least indirect contact with the corresponding gas exchange valve and further including a one-way valve in a region of a bottom of the housing, and a separate high pressure chamber into which the one-way valve opens being associated with each of the pressure pistons, the high pressure chamber extending axially between the bottom of the housing for the pressure pistons and a base of the housing, and the pressure pistons arranged in the common housing include a common reservoir.
