Latest Patents

Charles Knorr holds a patent for a hydraulic play compensating element. This invention is designed for a valve control mechanism in internal combustion engines. The hydraulic play compensating element consists of an outer piston that is closed on one end and is insertable for displacement in the longitudinal direction within a bore of a structural element of the valve drive. It guides an inner piston for longitudinal displacement with slight play in a longitudinal bore. Both pistons encompass a high-pressure chamber that communicates via a check valve arranged in the inner piston with an oil reservoir provided in the inner piston. The inner piston is supported at its end facing away from the pressure chamber by a disc, which is fixed in the bore of the structural element of the valve drive. The disc engages the bore of the inner piston with radially resilient clamping projections upon contacting the end of the inner piston facing away from the pressure chamber.
