Abstract
An apparatus for performing high-speed interruption of high-speed fluid jets ( ) of the type used to cut food, plastics, wood, metal, and other products. The water jet ( ) is interrupted by a blocking bar ( ) mounted on a housing ( ). The blocking bar ( ) is pivoted by actuators so that the bar is disposed away from the high-speed fluid jet ( ) in the open position and blockingly intersects the high-speed fluid jet ( ) when in the blocking position. At least one of the actuators is an electromagnet assembly ( ) and ( ) having a selectively energizable coil ( ) such that energizing the coil ( ) will induce a magnetic field. The blocking bar ( ) has an area of high magnetic permeability ( ), wherein the bar ( ) may be pivoted by application of the magnetic field generated by the coil ( ) upon the area of high magnetic permeability ( ).
