Document Type and Number:
WIPO Patent Application WO/2013/085046
Kind Code:
A1
Abstract:
According to an embodiment of the present invention, a valve device (1) includes a movable member (9 or 5) that operates in conjunction with valve opening/closing and a stationary member (10 or 4 or 8) that makes sliding contact with or abuts against the movable member (9 or 5). The valve device (1) is integrally provided with a built-up part (11 or 211) on a sliding contact surface or abutting section of the movable member (9 or 5) and/or the stationary member (10 or 4 or 8). The built-up part (11 or 211) is formed by generating a pulsed discharge between a processed section of the movable member (9 or 5) or the stationary member (10 or 4 or 8) and an electrode (102) constituted of a molded body having a metal as the main component, and welding and stacking the material of the electrode (102) onto the surface of the processed section.
