Abstract

A variable cam timing phaser for an internal combustion engine having at least one camshaft comprising a housing and a rotor. The housing has an outer circumference for accepting drive force. The rotor has a connection to the camshaft coaxially located within the housing. The housing and the rotor define at least one vane separating a chamber in the housing. The vane is capable of rotation to shift the relative angular position of the housing and the rotor. A portion of the outer circumference of the housing is supported by a journal bearing fixed to a non-rotating part of the engine, which may be the engine block or the cylinder head.
