Variable swash plate compressors recently have been used to improve fuel efficiency and SCM 435 or UNS C67300 were used as the material to manufacture them.As a result of structure analysis through static analysis that used ANSYS, SCM 435 currently being used was found structurally safe as it has that maximum stress is within the allowable range of their material property. Therefore, UNS C67300 was found to generate better fuel efficiency than the existing SCM 435 through structure analysis for automotive variable swash plate air conditioning compressor.

This work presents a simple design procedure of a pressure compensator of a swash plate type variable displacement axial piston pump (VDAPP). The route of the work mainly focuses on static design through balancing the torque given by the pump pistons, rate cylinder and strok- ing cylinder on the swash plate during cut-in (maximum flow) and cut-off (minimum flow) pressure condition of the system with an objective of minimizing the output pressure ripples. The outcome in terms of pressure from the dynamic simulation of the designed compensator with pump has been compare with experimental result obtained from a reference commercial pump has compensator with duel spool. The model has been used for performance prediction for wide variations of the load valve area settings.
