Title:
ON-OFF VALVE
Document Type and Number:
WIPO Patent Application WO/2022/173061
Kind Code:
A1
Abstract:
An on-off valve (1A) comprises: an elastic space part (2) including a hard magnetic elastic body; and an elastic-space-part deformation-causing element (6) that deforms the elastic space part (2) by a magnetic force. The elastic-space-part deformation-causing element (6) deforms the elastic space part (2) by at least any one of an attractive force or a repulsive force between the elastic-space-part deformation-causing element and the hard magnetic elastic body due to the magnetic force, a restoring force of at least either the elastic space part or the hard magnetic elastic body, and a resultant force of those forces, to thereby carry out an open mode for opening a space (S1) formed in the elastic space part (2) and a closed mode for closing the space.
