摘要：
A water jet assembly includes a faceplate with at least one opening, a housing constructed to cooperate with the faceplate, and a mover disposed within a chamber of the housing. The mover is configured to move between a first position adjacent the at least one opening of the face plate and a second position offset from the faceplate to provide a variable volume within the chamber. The water jet assembly also includes an exciter connected to the housing and configured to transition the mover between the first position and the second position to increase and decrease the volume to move fluid into and out of the chamber via the at least one opening.
