The present invention relates to a variable camshaft adjuster (VVT) for an internal combustion engine with a VVT component, preferably a locking disc, composed of material produced from powder metal with a locking bore, which extends from a first surface of the VVT component, preferably the locking disc, into this, wherein a locking bolt of a variable valve control engages into the locking bore and the locking bore has a connected oil duct which also extends from the first surface into the VVT component and discharges radially into the locking bore, wherein a base of the locking bore has an elevation, preferably in the form of an elevated shoulder which serves as a bearing surface of the locking bolt and the oil duct has a depth which is smaller than that of the locking bore. A VVT component, in particular a locking disc as well as a method for producing the locking disc or the camshaft adjuster are furthermore claimed.
A variable camshaft adjuster (VVT) for an internal combustion engine with a VVT component composed of material produced from powder metal and having a first surface, a locking bore extending from the first surface, and an oil duct extending from the first surface and connecting to the locking bore that discharges radially into the locking bore, wherein the locking bore being engageable with a locking bolt, wherein a base of the locking bore has an elevation which serves as a bearing surface of the locking bolt, wherein the base of the locking bore is lower than a base of the oil duct at least by a factor of 2 from the first surface, and wherein the oil duct has a depth which is smaller than that of the locking bore.
A method for producing a variable camshaft adjuster (VVT) for an internal combustion engine with a VVT component, wherein the VVT component comprises a first surface, a locking bore, and an oil duct, wherein the VVT component is produced from powder metal material, wherein the locking bore and the oil duct are formed starting from the first surface of the VVT component, wherein a base of the locking bore is lower than a base of the oil duct at least by a factor of 2 from the first surface, and wherein a base of the locking bore is formed deeper in the VVT component than a base of the oil duct.
