範囲第１項記載の送液ダンパー。[Scope of Claim for Utility Model Registration] (1) A liquid-feeding damper for eliminating pulsating flow that occurs when a pump is used to feed liquid, gas, etc., and the damper is provided in a part of the liquid-feeding path from the pump. A cylinder and a detection device that detects a pulsating flow component during liquid feeding, and a mechanism that moves a piston of a damper cylinder in a direction to reduce the detected pulsating flow component in accordance with an output from the pulsating flow detection device. A liquid delivery damper characterized by: (2) A position detection device for the upper and lower limit levels is attached to the above damper cylinder, and when the piston reaches either the upper or lower limit level, the moving direction of the piston is reversed according to the output from the position detection device, so that the piston is always at the center of the cylinder. Claim 1 for utility model registration characterized by movable parts
Liquid delivery damper as described in section. (3) The liquid feeding damper according to claim 1, wherein the signal level for reversing the piston in accordance with the output from the position detection device is set to a level that does not cause pulsation.
