  • Patent number: 11933314
    Abstract: A compressor wheel for a compressor of a turbocharger has a hub and a multiplicity of blades on the hub. In intermediate spaces of the multiplicity of blades, a channel is in each case formed between a suction side and a pressure side. The channel guides fluid that flows in axially in relation to a rotation axis radially or radially-axially outward. The hub in relation to the rotation axis is contoured such that the hub has a rotationally symmetrical portion and a non-rotationally symmetrical portion. On the non-rotationally symmetrical portion, a transition between the hub and each of the blades is embodied with a radiused connection and facing the suction side has a region of modified thickness. A region formed by control rays is generated in at least one channel between the suction side and the pressure side on the hub. A method produces the compressor wheel.

  • Patent number: 11885245
    Abstract: An oil pressure actuated or torsion assisted phaser with a lock pin that has a position which shuts off communication between the advance and retard chambers and the front cam bearing and/or oil control valve, effectively acting as a shutoff valve and preventing leakage of oil from the advance and retard chambers. The prevention of leakage maintains oil in the phaser after engine shutdown. Additionally, by shutting off communication between the advance and retard chambers and the oil supply, the side load on the lock pin from the oil pressure torque on the rotor vanes during unlocking of the lock pin can be reduced or eliminated.
