Abstract (en)
[origin: WO2012069211A1] A hydraulic actuating system is proposed, in particular for gas exchange valves of reciprocating-piston internal combustion engines, having a pressure source for the hydraulic medium and having at least one pressure accumulator which can be connected to the pressure source and has a piston which can be displaced in a bore, a compression spring and a supporting element for the compression spring with a central opening (3), which supporting element is fixed by means of a spring ring, wherein the supporting element is configured as a spring supporting plate (1), the axial extent of which is considerably shorter than that of the piston.
