Camshaft phaser with dual lock pins and a passage within the camshaft phaser connecting the lock pins |
摘要 |
A camshaft phaser is provided for varying the phase relationship between a crankshaft and a camshaft in an engine. The camshaft phaser includes a stator having lobes. A rotor is disposed within the stator and includes vanes interspersed with the stator lobes to define alternating advance and retard chambers. A primary lock pin is provided for selective engagement with a primary lock pin seat for limiting rotation between the rotor and stator to a range between full advance and full retard. A secondary lock pin is provided for selective engagement with a secondary lock pin seat for preventing rotation between the rotor and the stator at a predetermined position within the range. A cap is disposed axially adjacent the rotor to define a bridging lock pin oil passage therebetween. The bridging lock pin oil passage provides fluid communication between the primary lock pin and the secondary lock pin.
