Abstract: A centrifugal blower is described herein. The centrifugal blower may be a belt-driven geared centrifugal blower. The centrifugal blower may comprise an impeller, an inlet, and an outlet. The impeller pulls air in through the inlet, compresses and speeds up the air, and directs the air out the outlet. A motor may power a pulley system coupled to the belt that, in turn, drives a gear set. The gear set then drives the impeller. A mounting frame for the centrifugal blower may comprise a plurality of mounting holes for increasing the airflow to the gear set for cooling there. A belt tensioner may be coupled to the pulley system for setting a preload in the pulley system. An adjustment system for adjusting the tension provided by the belt tensioner is disclosed.

Abstract: A multi-chamber blowoff valve is provided for releasing excess air pressure from a duct system associated with a vehicle. The blowoff valve has a valve housing, an engine-air interface, and a multiple piston assembly. The valve housing is configured to secure to the duct system at a duct-air interface. The engine-air interface is configured to allow air in and out of the valve housing. The multiple piston assembly is disposed within the valve housing and includes an upper piston and a lower piston that move in unison. The multiple piston assembly is configured to be in a closed position while a pressure differential is above a certain threshold and to be in an open position while the pressure differential is below said certain threshold. While in the open position, a portion of the air in the duct system is released.

Abstract: A supercharger assembly includes a dry-running CVT coupled to a speed multiplying gear set, which is in turn coupled to a centrifugal supercharger. The CVT includes a CVT housing which has an opening formed therein to provide access to a face of the driven pulley, and a plurality of equally spaced bolt receivers arranged in a circle around the opening. The gear assembly includes a gear housing formed separate from the CVT housing. The gear housing has a plurality of bolt holes formed in it which are arranged in a circle and alignable with respective ones of the bolt receivers. The gear housing is selectively rotatable relative to the CVT housing by moving each of the bolt holes from alignment with a first respective one of the bolt receivers and into alignment with a second respective one of the bolt receivers and then installing fasteners therein.

Abstract: A compressed air delivery system in which power from a power supply is transmitted to a rotary air compressor through a dry running, continuous variable transmission (CVT) utilizing a belt coupled between two pulleys enclosed within a CVT housing. The air pressure differential created by the rotary air compressor is used to urge cooling air through the CVT to cool the CVT belt. The pressure differential may be utilized to push cooling air into the CVT housing or to draw cooling air through the CVT housing. In one embodiment, a portion of the compressed air discharged from a supercharger may be routed through a bleed line and into the CVT housing.

Abstract: A compressor airflow controller is operable to control airflow through a centrifugal compressor. The controller drives the centrifugal compressor and determines if a flow irregularity (e.g., an error in gas flow velocity) has occurred. If a flow irregularity is determined, the controller reduces the irregularity by adjusting compressor operation to thereby change the compressed gas flow.
