Camshaft phase regulator

A camshaft phase adjuster, comprising:

• a rotor, a stator, a locking pin and a one-way valve;
• the stator comprising a stator body having a substantially cylindrical shape and a plurality of protrusions protruding radially inwardly on an inner side of the stator body,
• the rotor comprising a rotor inner core having a substantially cylindrical shape and a plurality of rotor blades protruding toward a radially outer side of the rotor inner core,
• the rotor being rotatably mounted in an inner space of the stator body, the plurality of protrusions defining a plurality of inner cavities by fitting with an outer peripheral wall of the rotor inner core, and one of the rotor blades extending into each of the inner cavities and defining a first chamber and a second chamber in the inner cavities,
• a first oil hole, a second oil hole and a locking pin hole formed in the rotor inner core, the first oil hole connecting an engine fluid passage and the first chamber, the second oil hole connecting the first chamber and the second chamber, the first oil hole and the second oil hole both passing through the locking pin hole;
• the locking pin being located in the locking pin hole and being switchable between a first position and a second position;
• a one-way valve provided at the second oil hole;
• wherein, when the locking pin is in the first position, the first oil hole is unblocked, the one-way valve is switched off and the second oil hole is blocked, and
• when the locking pin is in the second position, the first oil hole is blocked by the locking pin, the one-way valve is switched on, and the second oil hole is unblocked.
