Publication number: 20150258492Abstract: A compressed air drying device includes a support case, a drying container installed in the support case, and a cover installed on the support case while covering the drying container. In load operation, compressed air that flows from an inlet of the support case is dried by a desiccant, and the dried compressed air is discharged. In unload operation, the compressed air inside the cover is passed through the inside of the drying container and oil and water is drained from a drain outlet. The compressed air drying device further includes an inlet opening/closing device that opens the inlet in the load operation, and closes the inlet in the unload operation.Type: ApplicationFiled: October 11, 2013Publication date: September 17, 2015Inventors: Tomoya Nishihara, Ichiro Minato, Masanori Momoki

Publication number: 20150217744Abstract: The operation of an air compressor is controlled to control engine performance to thereby improve the performance of the vehicle. A compressor (4) driven by an engine (3) of a vehicle and supplying compressed air to loads (51-54) is controlled by an ECU (2). A loaded state and an unloaded state of the compressor (4) are switched between each other according to the requirements from the loads (51-54). When the vehicle requires braking force, the compressor (4) is set to the loaded state irrespective of the requirements from the loads (51-54).Type: ApplicationFiled: April 15, 2015Publication date: August 6, 2015Applicant: Nabtesco Automotive CorporationInventors: Ichiro MINATO, Hiroki HASEBE
