Low-noise duplex supercharger

The utility model discloses a low-noise duplex supercharger which comprises a cylinder body, a control valve, a first large piston, a second large piston, a first left side small piston, a first right side small piston, a second left side small piston and a second right side small piston. The control valve can control the first large piston and the second large piston to reciprocate in the cylinder body, so that the first left side small piston, the first right side small piston, the second left side small piston and the second right side small piston are driven to reciprocate, and pressurized oil liquid is continuously output. According to the low-noise duplex supercharger, duplex work of the pistons can be achieved, pressurized oil liquid can be continuously output, and more output flow can be obtained. 本实用新型公开了一种低噪音双联增压器,该低噪音双联增压器包括缸体、控制阀、第一大活塞、第二大活塞、第一左侧小活塞、第一右侧小活塞、第二左侧小活塞和第二右侧小活塞；控制阀能够控制第一大活塞和第二大活塞在缸体内进行往复移动，从而带动第一左侧小活塞、第一右侧小活塞、第二左侧小活塞和第二右侧小活塞进行往复移动，连续输出增压油液。本实用新型的低噪音双联增压器，可以实现活塞的双联工作，连续输出增压油液以及获得更多的输出流量
