Abstract

Provided is a novel cylinder valve cavity small piston structure. A cylinder bottom is connected with a cylinder wall, the cylinder wall is regularly provided with an air inlet channel and a cylinder cover, a valve cavity is formed in one side of the cylinder cover, a small piston is installed inside an inner cavity of the valve cavity, the small piston is fixed through a bonnet, an air guide pipe is installed on the small piston, the air guide pipe is connected with a valve nozzle through the valve cavity, the valve nozzle is connected with a valve, a valve plug is installed on the other side of the cylinder cover, a spring is arranged inside the valve cavity of the valve plug, one end of the valve plug is connected with the air inlet channel, and the other end of the valve plug is in butt joint with the air guide pipe.

Description

technical field [0001] The invention relates to a valve cavity small piston structure, in particular to a novel cylinder valve cavity small piston structure, which belongs to the technical field of cylinder components. Background technique [0002] The small piston structure of the cylinder valve cavity is an important component in the cylinder configuration. In the existing small piston structure of the cylinder valve cavity, the structure of the combination of cylinder wall, cylinder head, intake port, valve cap and small piston is generally adopted. In the small piston structure of the cylinder valve cavity with this structure, because the valve cavity and the small piston are independent, the coordination between the intake port and the air guide pipe is not smooth, and there are common problems such as complex structure, poor lubrication of the valve cavity, slow operation of the small piston, and disassembly. Troublesome installation and inconvenient maintenance. Con...
