Abstract (en)
[origin: US4881499A] A hydraulic play compensating element adapted to be positioned in the valve train of an internal-combustion engine is described which comprises a cylinder part closes at one end and a piston part slidable longitudinally in the latter. The piston part contains a supply chamber which is pressurized by lubricating oil from the lubricating oil circuit and which is separated from a pressure chamber by a connecting duct controlled by a valve. In order to switch off the play compensating function of the play compensating element during engine braking service, a shut-off valve is provided in the supply chamber for closing or opening the connecting duct as a function of the lubricating oil pressure in the supply chamber.
