A variable camshaft phaser is provided having a stator attached to a driving part, and a rotor located within the stator and attached to a driven part. First and second cover plates are located on respective first and second axial sides of the stator. Inwardly directed vanes of the stator, the rotor, and the first and second cover plates define at least one chamber. Radially outwardly directed vanes of the rotor divide the at least one chamber into an advance side working chamber and a retard side working chamber. A locking pin bore is located in the rotor, and a locking pin is located in the locking pin bore. One of the first and second cover plates includes a locking pin receiving opening. A magnetic part is located in the locking pin receiving opening to remove metallic particles and contaminants from the flow of pressurized hydraulic fluid.

Provided is a shield molding blank which has an uneven structure in which an air gap 4 is formed between metal plates 2, 3 formed in overlapping wavy shapes comprising recesses and projections that are periodically continuous in two directions orthogonal to each other, the shield molding blank being cut in a desired expanded shape and having peripheral edges folded. With the shield molding blank, it is possible to mold a shield having improved shield characteristics such as a heat-shielding property and a sound-shielding property.

A rocker arm has two side walls and two webs which run transversely with respect to the side wall. The webs connect the side walls to one another on end-side sections, wherein a valve stem support is configured on one of the webs, and a spherical cap is configured on the other web. A cam roller is arranged in a roller pocket which is delimited by the webs and the side walls. The cam roller is mounted rotatably on a roller axle which is fixed in the side walls. Projections are arranged within the roller pocket such that they are spaced apart from the respective web to guide the cam roller. The projections extend from the side walls in the direction of the cam roller to form guide surfaces which interact with end surfaces of the cam roller.
