Title:
WATER-JETTING DEVICE IN WATERJET LOOM
Document Type and Number:
Japanese Patent JP3783933
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a water-jetting device suitable for automation of a waterjet loom.
SOLUTION: High-pressure water in a water-feeding source 29 is fed to a weft-insertion pump 64 by overcoming the air pressure in a pressurized chamber 321 in the weft-insertion pump 64 when an electromagnet valve 49 is in an opened state in which the water can be fed, and an electromagnet valve 45 is in a closed state in which the water cannot be fed. When the electromagnet valve 49 is in a closed state in which the water cannot be fed, and the electromagnet valve 45 is in the opened state in which the water can be fed, the water in a water-storing chamber 641 is fed to a weft insertion nozzle 47 by the air pressure in the pressurized chamber 321. The electromagnet valve 45 is controlled by excitation by the indication control of a controller 57.
