A variable cam timing phaser includes a housing disposed about an axis and having an inner housing surface defining a housing interior. A variable cam timing phaser includes a rotor movable between an advanced position and a deferred position. The rotor includes a hub and blades, wherein the rotor and the housing define a chamber. The vane further defines the chamber into an advance chamber and a delay chamber. The variable cam timing phaser also includes a control valve assembly including a valve housing and a control piston. The variable cam timing phaser also includes a chamber biasing assembly disposed in one of the advance chamber and the delay chamber and configured to bias the rotor into a predetermined position between the advance position and the delay position. The chamber biasing assembly includes a chamber piston, a chamber biasing member, and a chamber check valve. 可变凸轮正时相位器包括绕轴线设置的壳体并且具有限定壳体内部的内壳体表面。可变凸轮正时相位器包括能够在提前位置和推迟位置之间移动的转子。转子包括毂部和叶片，其中转子和壳体限定腔室。叶片将腔室进一步限定为提前腔室和推迟腔室。可变凸轮正时相位器还包括包括阀壳体和控制活塞的
