CAMSHAFT PHASER WITH A ROTOR NOSE OIL FEED ADAPTER

摘要

A camshaft phaser, including: a drive sprocket; a phaser section including a rotor with a first radially aligned channels, first axially aligned channels connected to the first radially aligned channels, and chambers formed by the rotor and a stator; and a rotor nose separately formed from the phaser section and non-rotatably connected to the phaser section, extending past a front side of the phaser section in an axial direction, and including second radially aligned channels and second axially aligned channels connected to the second radially aligned channels and the first axially aligned channels. The second radially aligned channels are arranged to receive fluid for the plurality of chambers to phase the phaser. The first radially aligned channels and the first and second axially aligned channels form respective flow paths for the fluid from the second radially aligned channels to the plurality of chambers.

1. A camshaft phaser, comprising:
a drive sprocket arranged to receive torque; a phaser section including:
a stator non-rotatably connected to the drive sprocket;a rotor at least partially rotatable with respect to the stator and including a first plurality of radially aligned channels;a first plurality of axially aligned channels connected to the first plurality of radially aligned channels; and,a plurality of chambers formed by the rotor and the stator and open to the first plurality of radially aligned channels; and, a rotor nose:
separately formed from the phaser section and non-rotatably connected to the phaser section;extending past a front side of the phaser section in a first axial direction; and, including:
a second plurality of radially aligned channels in a radially outer surface of the rotor nose assembly; and,a second plurality of axially aligned channels connected to the second plurality of radially aligned channels and in hydraulic communication with the first plurality of axially aligned channels, wherein: the plurality of chambers is arranged to circumferentially position, in response to fluid pressure in the plurality of chambers, the rotor with respect to the drive sprocket; the second plurality of radially aligned channels is arranged to receive fluid for the plurality of chambers; and, the first plurality of radially aligned channels and the first and second pluralities of axially aligned channels form respective flow paths to the plurality of chambers.
