Abstract: A rotary damper includes a housing and a vane. There is an indentation in the housing which permits fluid to flow readily from one side of the vane to the other during part of the rotary stroke. At the end of the rotary stroke, there is an alternative path for fluid to take from one side of the vane to the other, and this path preferably includes an adjustable aperture so the amount of damping at the end of the stroke can be adjusted.

Abstract: A rotary actuator and a linear actuator are combined to provide an output shaft with independent linear and rotary motion. The linear actuator causes the rotary actuator to move linearly, and there is a guide which restricts the movement of the rotary actuator to linear motion and a bearing which receives the output shaft of the rotary actuator to prevent orbiting and deflection of the rotary output shaft.

Abstract: A multi directional actuator capable of moving a shaft in at least two directions independently including one linear and one rotary movement. A base plate is provided to receive a first actuator having a linearly moving shaft which is extended from and retracted into the actuator. A second actuator is connected for movement by the first actuator and where the second actuator operates an output shaft which is selectively rotated through a portion of an arc. A guide arrangement is provided to direct movement of the second actuator by the first actuator and to journal the shaft of the second actuator to prevent orbiting and deflection of the shaft of the second actuator. Limit switches can be provided to indicate end of the stroke of the linear and rotary actuators and the first and second actuators can be separated to allow use of limit stops to limit rotation of the shaft of the second actuator.
