booster cylinder

Abstract

The invention relates to a pressure cylinder which comprises a cylinder body, a piston of an inner cavity of the cylinder body and a piston rod. The piston rod stretches out of the cylinder body in the axial direction. The cylinder body is partitioned into a first cavity body and a second cavity body through the piston. One end of the cylinder body is provided with a first one-way valve and a valve. The other end of the cylinder body is provided with a second one-way valve. Both the side wall of the first cavity body and the side wall of the second cavity body are provided with fluid channels. When gas is compressed, the piston conducts piston motion in the cylinder body, and the gas is compressed after entering the cylinder body through the first one-way valve and the second one-way valve and then is discharged out of the cylinder body through the valve. When the piston compresses the gas to move to the positions between fluid inlets and fluid outlets of the fluid channels, the compressed gas sequentially flows through the fluid inlets, the fluid channels and is discharged through the fluid outlets, and the gas is transferred to the other cavity body partitioned through the piston; through reciprocating motion of the piston, the gas is transferred uninterruptedly in the two cavity bodies partitioned by the piston, bidirectional compression of the gas is achieved, and working efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the technical field of fluid devices, in particular to a booster cylinder. Background technique [0002] The pneumatic cylinder is a pneumatic actuator that converts pneumatic energy into mechanical energy and performs linear reciprocating or swinging motion. [0003] At present, the common pressurized cylinder is an air internal design, which includes a cylinder body, a piston set in the air chamber inside the cylinder body, and a piston rod fixed to the piston. A valve is set on the cylinder body to control the flow of fluid. In the cylinder; the cylinder and the plug form a closed circuit, and the reciprocating movement of the piston inside the cylinder is controlled by the piston rod to achieve pressurization; although the power is small, the application is more flexible.

In the cylinder; the cylinder and the plug form a closed circuit, and the reciprocating movement of the piston inside the cylinder is controlled by the piston rod to achieve pressurization; although the power is small, the application is more flexible

[0004] However, because the piston moves in the cylinder and pressurizes in one direction, the work efficiency is low, and it is difficult to add the air pressure to the high pressure state in the short-stroke cylinder
