Sliding Vane Motion

Sliding Vane is a variation of Combined Linear/Angular motion. In the Combined Linear/Angular motion type, the path of linear translation is user-specified, and is not changed by the rotational motion.

Sliding Vane motion is the opposite: the location of the axis of rotation is specified by the user, does not change, and controls the direction of linear translation.

The most common application of this type of motion is found in sliding-vane positive displacement pumps.

Vanes or pistons rotate about the center-line of the impeller, but translate radially. The direction of linear travel changes at every angular position. The axis of rotation, however, remains constant.

This diagram shows how the direction of translation changes based on angular position:

Sliding vane motion is specified only as a user-prescribed motion. Flow-driven sliding vane motion is not currently supported.
