Title:
CONTROL VALVE FILTER AND CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/2016/047371
Kind Code:
A1
Abstract:
The purpose of the invention is to provide a control valve filter that does not require extra components or increased complexity to manufacture, and is unlikely to be deformed or damaged when mounted on a control valve main body; and to provide a control valve comprising said control valve filter. The control valve filter comprises a frame member 5 fitted into a frame-housing part 10 provided on the edge of an opening of a port part 3 of a control valve main body 2, a filter member 6 provided to the frame member 5, and a secured part 7 formed integrally with the filter member 6 and secured to the port part 3 by the frame member 5 being fitted into the frame-housing part 10; therefore, unlike the prior art, the diameter of the frame member 5 does not need to be increased when the control valve filter 1 is attached to the port part 3. This makes it possible to prevent damage to the frame member that would be caused by this diameter enlargement. Because the control valve filter 1 is attached to the port part 3 by the secured part 7 being secured to the port part 3, the number of components is not increased and manufacturing requires no further complexity.
