Hydraulic buffer for gun

Abstract

A hydraulic buffer for a gun comprises a cylinder body, a front plug and a rear plug, wherein the end part of a piston is mounted in the cylinder body in a way that a piston rod of the piston passes through the front plug; a valve is mounted in the end part of the piston, is limited through a hole retainer ring and can perform front-back relative movement in the length direction of the cylinder body in the end part of the piston; a stop pin, a steel ball and a screw are arranged on the rear plug; a return spring is arranged between the end part of the piston and the rear plug; a liquid flow hole is formed at the root segment of the piston rod; and a center liquid flow hole is formed in the center of the valve, and lateral liquid flow holes are formed on the two sides of the valve. The hydraulic buffer has the advantages of small size, compact and simple structure, convenience in installation, high reset speed and good buffering effect, and can meet buffering requirements of different guns through designing different technical parameters.

Description

technical field [0001] The invention relates to a hydraulic buffer device for firearms, in particular to a hydraulic buffer suitable for small-caliber firearms. Background technique [0002] Small-caliber automatic weapons such as firearms generally use spring-loaded buffers. The principle and structure of the spring buffer are simple, and the buffer capacity depends on the stiffness and preload of the spring. The disadvantage is that the stronger the buffering capacity, the more energy stored during work, which will increase the re-entry speed of the automatic machine, resulting in an increase in frequency and re-entry energy, which is very unfavorable to the accuracy and controllability of the firearm. Therefore, the buffer capacity of the spring buffer appears to be very limited. At present, hydraulic buffers are mainly used for large-caliber artillery and small and medium-caliber automatic guns. Because the volume of the hydraulic buffer is relatively large and the st...
