CAM PHASE ADJUSTER WITH A PLURALITY OF SPRINGS
The camshaft adjuster is a plurality of return springs which are in parallel to one another in a spring.
1 . A camshaft phase adjuster comprising:
a stator and a rotor adjustable to the stator in a circumferential direction by a pressure medium;
at least one spring chamber proximately located adjacent to the stator and the rotor; and
a plurality of return springs proximately arranged in the spring chamber, each of the springs having a rotor connecting end for connecting to the rotor and a stator connecting end for connecting to the stator, the return springs configured to rotate the rotor relative to the stator into an initial position absent pressure from the pressure medium.
2 . The adjuster of claim 1 , wherein
the spring chamber is axially adjacent to the stator and the rotor.
3 . The adjuster of claim 1 , wherein
the plurality of return springs are arranged axially adjacent to one another in the spring chamber.
4 . The adjuster of claim 1 , wherein
the plurality of return springs is 2 or more.
5 . The adjuster of claim 1 , wherein
the return springs are flat, spiral springs.
6 . The adjuster of claim 1 , wherein
each of the return springs has an equal strength.
7 . The adjuster of claim 2 , wherein
the plurality of return springs is 2 to 4.
8 . The adjuster of claim 1 , wherein the return springs are not of equal strength.
