ABSTRACT:
An apparatus and method for performing high speed interruption of the flow of a very fine, high pressure, high speed water jet 12 of the type used to cut foods, paper, and other goods. The water jet 12 is interrupted by a pivotal blocking bar 22 within a blocker housing. The blocking bar 22 is pivoted in a collar 24b to a first desired position out of the path of water jet 12 or to a second desired position for blocking the path of water jet 12. A pivot arm 28, controlled by an output shaft 30 of a rotary actuator 32, controls the rotation of the blocking bar 22. A high pressured airflow is introduced into the device for controlling the exhaustion of blocked water within the device and for cooling the rotary actuator 32.
