Accessory drive and particle trap

摘要

An accessory drive system to provide engagement between a driving input source and a driven accessory unit includes a housing attachable to the input source. A fluid suction port and a discharge port are defined by the housing and the suction port is in fluid communication with a fluid reservoir of the input source. The fluid discharge port is in fluid communication with the suction port and a gear assembly is rotatably supported by the housing. The accessory unit is operably engaged by the input source through the gear assembly and the gear assembly is structured and arranged within the housing to urge fluid away from the housing in response to movement of the gear assembly.
