Title: Flow control valve
Inventor: OKABE SHINICHI
IPC: F02M69/32
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To prevent a valve element from irregularly chattering. SOLUTION: A valve element 120 is formed into a cylindrical shape, and the end section on the side of the valve port 113 of the valve element 120 (cylindrical section 121) is tapered to reduce the area where the valve element 120 and a housing 110 contact with each other. Since this constitution reduces the area of a portion in parallel with the housing 110 out of the valve element 120 and makes relatively large space 121c (space in the cylindrical section 121) exist after passing of air flow (jet flow) through a gap σ, the air pressure near the valve element 120 can be prevented from reducing. Therefore, since the vibration exciting force acting on the valve element 120 due to pressure difference can be reduced, the irregular vibration of the valve element 120 can be prevented.
