  • Patent number: 9429048
    Abstract: A support element for the valve train of an internal combustion engine, having a hollow cylindrical housing that holds a displaceable piston. The piston has a hollow cylindrical pressure part and a pot-shaped work part axially adjacent thereto. An inner space of these parts forms a storage space for hydraulic medium. A high pressure space is defined by a base of the work part and the housing. The storage space and the high pressure space are connected hydraulically by a non-return valve with a ball for automatic lash compensation of the valve train. The piston is supported by a compression spring on the housing base, and a retaining ring is arranged radially between the pressure part and the housing, which limits axial travel of the piston. The ball is movably held in the base of the work part in an axial ball guide having first and second integrally formed ball seats.
