摘要: Embodiments of the invention provide an actuator (100) for a valve assembly. The actuator can include a yoke (146) with at least one bore (196), a first rod assembly (136), and a first slide member (148) seated within the at least one bore and pivotally connected to the first rod assembly. The yoke can be configured to rotate about a yoke axis (198) to actuate the valve assembly. The first rod assembly can be configured to move in a first direction transverse to the at least one bore and the yoke axis. The first slide member can be configured to slide telescopically within the at least one bore as the first rod assembly moves in the first direction to transmit torque to the yoke for actuation of the valve assembly.

摘要: To generate a setpoint signal to stroke a valve during a partial-stroke test, a first target is determined for the setpoint signal based at least on a travel displacement threshold, the travel displacement threshold corresponding to a desired extent of travel of the valve during the partial-stroke test; the setpoint signal is ramped from an initial value to the first target, during a first time interval; subsequently to the first time interval, the setpoint signal is maintained at the first target during a second time interval; a second target is determined for the setpoint signal based at least on the initial value; and during a third time interval subsequent to the second interval, the setpoint signal is ramped from the first target to the second target in a direction opposite to the ramping of the setpoint signal during the first time interval.

摘要: A valve assembly for an exhaust system of a vehicle. The valve assembly includes a housing, a valve shaft and a valve plate. The housing defines an inlet, an outlet, and a longitudinally exhaust gas passageway in fluid communication with the inlet and the outlet. The valve shaft is rotatable. The valve plate is coupled to the valve shaft and is rotatable between a first position restricting exhaust gas flow through the exhaust gas passageway, and a second position whereat exhaust gas flow through the exhaust gas passageway is less restricted. The first housing includes spaced apart ears integral with and laterally extending from the first housing. The ears opposing each other. The shaft includes an axis of rotation being positioned at the ears and outside of the exhaust gas passageway.

摘要: A device for actuating a valve by means of a rack meshing with an elliptical pinion connected with a sleeve so that one transmits a torque to the other. The connections between the pinion and the rack as well as the sleeve are separable, so that the angular reference positions of the pinion relative to both the rack and the sleeve can be adapted according to a predefined variation in the torque required for actuating the valve.

摘要: A rotary fluid regulator (1, 300) has a housing (2) with at least one inlet opening (3, 4) and at least one outlet opening (5). A valve element (7, 100) is received rotatably in the housing (2) and is a hollow fluid duct (8). A drive element (19, 301, 401, 501) is provided to rotate the valve element (7, 100) so that a fluidic connection between the at least one inlet opening (3, 4) and the at least one outlet opening (5) can be adjusted or blocked. A brake element is provided for influencing or blocking the movement of the valve element.
