[origin: US2018163542A1] A hydraulic device for an internal combustion engine or a gearing system, the hydraulic device including a housing featuring a chamber wall structure which delineates a pressure chamber for a pressurised hydraulic fluid; an actuating member which can be adjusted in the housing relative to the chamber wall structure in an actuating direction and in an actuating counter direction opposite to the actuating direction in order to adjust the delivery volume or phase position; and a sealing element including a sealing structure and a spring structure which is supported or moulded on one of the chamber wall structure and the actuating member, preferably the actuating member, and presses the sealing structure into sealing contact with the other of the chamber wall structure and the actuating member with a spring force in order to seal off the pressure chamber. The sealing structure and the spring structure are moulded in one piece.
