Title:
ELECTRICALLY OPERATED VALVE
Document Type and Number:
WIPO Patent Application WO/2019/163319
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a highly reliable electrically operated valve with which it is possible to prevent foreign matter contained in a fluid (refrigerant) that is flowing therethrough from becoming trapped between a valve body and a valve seat and being pressed strongly against the same, thereby preventing the valve seat and the valve body from being scratched or dented, for example, and with which valve leaks are not liable to occur. An electrically operated valve 1 is configured in such a way that rotation of a rotor 57 is converted into a vertical movement of a main valve body 20 by means of a screw feed mechanism, wherein an auxiliary valve body 30 for opening and closing a valve port 9 is disposed around the main valve body 20 in such a way as to be capable of moving vertically, and the auxiliary valve body 30 is configured to close the valve port 9 before the main valve body 20 when the main valve body 20 is to close the valve port 9.
