<p>PURPOSE:To obtain a constant flow valve, which assures quiet operation, by furnishing the valve's secondary flow line with an expansion chamber to work as a damping chamber. CONSTITUTION:In the secondary flow line 2c of a constant flow valve is provided an expansion chamber 4 to work as a damping chamber. Thereby the jetting speed of the fluid flowing out of the throttle part 3A into the secondary flow line 2c is relieved at this expansion chamber 4, so that flow sound to increase with the flow speed can be reduced.</p> |
