An assembly for positioning a retaining ring includes a mandrel having an outer diameter smaller than an outer diameter of a rotor. The assembly also includes a seal assembly for sealing a circumferential retaining ring around the mandrel or the rotor, the seal assembly comprising a pair of seal plates situated around opposing ends of the retaining ring. Further, the assembly includes a hydraulic expansion device for providing a fluid pressure for hydraulically expanding the retaining ring until an inner diameter of the retaining ring is greater than the outer diameter of the rotor. Furthermore, the assembly includes a displacement device for providing axial movement of the seal assembly and the retaining ring.

Assembly for positioning a rotor retaining ring

Embodiments of the invention relate generally to rotor installation systems and, more particularly, to permanent magnet rotor installation systems, including those having an in situ magnetizer or magnet insertion device. In one embodiment, the invention provides a rotor installation system comprising: at least one magnetizer for permanently magnetizing a ferromagnetic material; and an arbor for receiving a rotor having at least one portion including a ferromagnetic material, wherein the at least one magnetizer is positioned relative to the arbor to allow permanent magnetization of the ferromagnetic material.

A plenum is surrounded by runners that spiral around the plenum sidewall to the entrances to the engine cylinders. The circumferential extent of each runner exceeds 360 degrees about a longitudinal axis of the plenum. Portions of the runners share common wall portions with portions of the plenum.

Integrated tuned induction system

An integrated tuned air induction system for an internal combustion engine comprises an air intake leading to an air filter compartment. The air filter compartment leads to a tube that extends horizontally past a bank of cylinders that is served by the system. The tube leads to a tubular extension piece that creates a 180 degree turn. After this turn, the airflow passes through an air body containing a valve that controls the induction airflow. After the air body, the airflow passes to a plenum zone that lies parallel to the first tube. Spiral runners arranged transversely to the length of the plenum zone communicate the plenum zone to the intake of each cylinder in the bank. The first tube, the runners, and the plenum zone are formed by a single plastic part. The air filter compartment is defined by an end wall of this part and a removable cover. An integral wall of the part serves to mount the part on the engine while providing support for the runners. The air body has slip fit sealed joints via which it connects into the system.
