Title:
FOREIGN BODY REMOVAL DEVICE AND REMOVAL DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/104050
Kind Code:
A1
Abstract:
The present invention is such that contact between components is avoided so that generation of noise or the like is prevented. This foreign body removal device is equipped with: a piston 27 that is movably supported in a cylinder 18; a nozzle 6 that jets the high-pressure air delivered by the piston; a biasing spring 33 that biases the piston; and a moving mechanism 8 that moves the piston. Of the moving directions of the piston, the direction in which high-pressure air is delivered is a delivery direction, and the direction in the opposite direction from the delivery direction is a force accumulation direction. The piston is moved in the force accumulation direction by the moving mechanism, and moved in the delivery direction by the biasing force of the biasing spring in response to the release of the moving force exerted by the moving mechanism. The cylinder is provided with: a piston supporting portion 19 that supports the piston; and a connection protrusion 20 that has a delivery path 20a for delivering the high-pressure air to the nozzle. The inner surface of an end of the piston supporting portion in the delivery direction is formed as a closed surface 22a. The delivery path is located further toward the force accumulation direction than the closed surface is.
