Title:
FLOW RATE CONTROL VALVE
Document Type and Number:
WIPO Patent Application WO/1999/049203
Kind Code:
A1
Abstract:
A flow rate control valve provided with a spring for urging a valve disc (103) in a closing direction, which valve disc is adapted to open and close a flow passage in a valve housing (101), a projecting portion extending toward a valve driving side in a recess formed in an upper surface of a bracket (108) to which a valve drive housing is fixed, a protective member (110a) extending from the valve drive housing toward the bracket, and an opening formed in the bracket so as to allow communication of a bottom portion of the bracket with the outside. This structure reduces the influence of heat from the valve housing and the bad influence of extraneous matter from the outside mixed in a fluid.
