as deep drawing methods are considered by forming the housing 11 from a steel sheet metal blank a reliable sealing of the device 1 is guaranteed whereby the device 1 can be used as a belt driven camshaft adjuster such camshaft adjusters are typically arranged outside of the cylinder head whereby a secure sealing of the device 1 is required leakage oil is collected by the formation of the housing 11 as a molded sheet metal part within the device 1 and can be fed back into the cylinder head via channels formed on the cylindrical section 19 alternatively between the section 19 and the camshaft an annular gap can be formed in order to lead leakage oil back into the cylinder head the first housing element 16 is advantageously sealed relative to the cylinder head by a radial shaft seal 20 arranged on the section 19 through the encapsulation of the stator 2 and the driven element 3 within the housing 11 cost intensive post treatment for sealing the driven element 3 normally formed as a porous sintered component can be eliminated any small leakage through the sintered material or at the sealing points is kept within the device 1 by the housing 11 and can be fed back into the cylinder head in the embodiment in which the pressure spaces 10 are closed pressure tight by a sealing disk 12 on the side of the device 1 facing away from the camshaft this.
