摘要： A fail-safe actuator for moving a part has in each case a drive (18, 118) by means of which a first or a second drive train (24, 26) can be moved. The drive trains (24, 26) in each case have their own output shaft (34, 38) and can be actuated independently of one another. An energy storage device is coupled with the second output shaft (38), wherein a holding device selectively holds the energy or releases it from the energy storage device, so that the second output shaft (38) can be moved. A rotary entrainment of the first output shaft (34) ensures that in the event of a failure of the drive (18) this is moved into a specified end position. The two output shafts (34, 38) are set in motion via gear wheels (32, 36) if the drive trains are actuated. An assembly unit consisting of actuator and moved part is also described.

摘要： Presented are a method, apparatus and valve assembly for preventing rotation. An exemplary valve assembly includes a butterfly valve rotatably moveable between a closed position and an open position, and a shaft extending from the butterfly valve and rotatable about a longitudinal axis to move the butterfly valve between the open position and the closed position. The valve assembly further includes an actuator having a body operable to maintain an end portion of the shaft, the actuator operable to cause the shaft to rotate about the longitudinal axis, a housing sized to retain a portion of the shaft, the housing operable to be in removeable contact with the body, a seal intermediate the body and the shaft, the seal having an outer sealing surface contacting the body and an inner sealing surface contacting the shaft, and an anti-rotation interface between the seal and the housing.

摘要： Exhaust gas recirculation valve actuator device in an internal combustion engine, comprising an actuator body housing where the stem of an exhaust gas recirculation valve, extends along an axial direction. A motor acts to move the recirculation valve along the axial direction X-X, to pass from an open configuration to a closed configuration. A transmission is interposed between the motor and the exhaust gas recirculation valve. The device also includes support and guide mechanism and a sealing mechanism, in correspondence of a connection interface of the actuator body with an associable valve body, which houses an exhaust gas passage duct, wherein the actuator body is mechanically separable/connectable from/to said associable valve body.

摘要： A method of designing a valve presenting an orifice of section that depends on the position of the valve member of the valve, which section can thus be controlled. The method includes determining a desired variation relationship for the flow section of the valve, which relationship defines a desired variation in the section as a function of time; setting a predetermined movement relationship for the valve member; and defining the shape of the fluid flow orifice in such a manner that, at each instant, if the valve member moves in compliance with the predetermined movement relationship, the flow section remains equal to the desired section. The method makes it possible to design a valve that is simple to control.

摘要： A flow control assembly for a fire sprinkler system includes a valve housing having an inlet opening and an outlet opening. The valve housing defines a fluid flow path that extends between the inlet opening and the outlet opening. A flow control valve is disposed within the fluid flow path. A swing check valve is disposed within the fluid flow path of the valve housing downstream from the flow control valve. The swing check valve includes a clapper that is connected to an actuator arm. An electrical switch is disposed outside of the valve housing. A mechanical linkage includes a first end that extends through the valve housing and engages with the actuator arm. The mechanical linkage also includes a second end that is coupled to the electrical switch. The first end translates with said actuator arm.
