Dual phaser assembled concentrically concentrically camshaft system

摘要

It possesses the concentric camshaft the stator which possesses rotary axis (14) to include it is possible the variable cam timing phase vessel for the internal combustion engine. The outer part rotor (20), it is possible to turn unrelated the stator (14) vis-a-vis rotary axis. The operational chamber of variable capacity outside 1st and 2nd (20b and 20c) in order to demarcate, the outer part vane (22) with the cavity (20a) with the outer part rotor (20) with relation can combination attach. The rotor which is located inside radial (30), unrelated and the stator (14) and the outer part rotor (20) it is possible vis-a-vis rotary axis to turn both and unrelated. The operational chamber of variable capacity inside 1st and 2nd (30b and 30c) in order to demarcate, the inside vane (32) with the cavity (30a) with the inside rotor (20) with relation can combination attach. When the chamber outside and inside 1st and 2nd (20b, 30b, 20c and 30c) communicating with compressed fluid source choice, it confronts mutually and the stator (14) outside for and the inside rotor (20 and 30) phase orientation makes easy.
