USING TORSIONAL ENERGY TO MOVE AN ACTUATOR |
摘要 |
An actuator for varying a compression ratio of an engine by varying by the rotary motion of a control shaft coupled to a variable compression ratio device. The actuator comprising: a housing assembly mounted to the engine; a rotor assembly coupled to the control shaft defining at least one vane separating a chamber in the housing assembly into a first chamber and a second chamber, the vane being capable of rotation to shift the relative angular position of the rotor assembly from a first rotational position associated with a first compression ratio to a second rotational position associated with a second compression ratio; and a control valve moveable to a first position in which torsional energy from the control shaft is permitted to rotate the rotor assembly in a direction from the first rotational position toward the second rotational position and to a second position opposite the first position. |
