Abstract
An assembly for an exhaust bypass valve of a two-stage turbocharger can include a first turbocharger stage; a second turbocharger stage; an exhaust bypass valve that includes an open state and a closed state; and a linkage mechanism that links the exhaust bypass valve to an actuator where the linkage mechanism includes a locked state for the closed state of the exhaust bypass valve.
Claims13
An assembly for an exhaust bypass valve of a two-stage turbocharger, the assembly comprising:
- a first turbocharger stage;
- a second turbocharger stage;
- an exhaust bypass valve that comprises an open state and a closed state;
- an actuator;
- and
- a linkage mechanism that links the exhaust bypass valve to the actuator;
- wherein the linkage mechanism comprises a locked, closed state wherein the linkage mechanism is in a locked position for the closed state of the exhaust bypass valve;
- wherein the linkage mechanism comprises a movable axle and a casing;
- wherein the casing comprises two parallel plates and at least one fixed support, and
- wherein each of the two parallel plates comprises a respective seating feature that comprises a notch that seats the movable axle or a guide that seats the movable axle;
- and
- wherein the linkage mechanism comprises at least one spring being operatively coupled to at least one of the at least one fixed support to apply a force to the movable axle wherein the force biases the movable axle with respect to the respective seating features of the two parallel plates.
