Problems solved by technology

However, when the pressure of the gas tank is lower than the rated pressure, the governor only uses the spring to push the piston to increase the speed of the diesel engine, and the function is not stable.
There is no pressure regulating mechanism at the end of the piston through the compressed air, and the effect is unreliable

Embodiment Construction

[0008] The present invention relates to a pneumatic controller used in internal combustion engine-driven air compressor equipment. There is a cylinder body 8 which can be made into a cylindrical shape, and a piston 6 and a piston rod 3 are installed in the cylinder body, and a sealing ring 12 is arranged in the piston 6. The outer end of the piston rod 3 is formed with an internal-combustion engine throttle cable connecting hole 1, and the outer wall of the cylinder body 8 is respectively formed with an air source joint 5 and a fixing piece 18 connected to the gas storage tank. The source joints are the two external connections of the pneumatic controller. The inner hole of the air source connector 5 is connected to the cylinder cavity, and the inner wall of the cylinder at the air intake place can be shaped with a groove 4 . There is a pressure chamber 7 at the other end of the cylinder body 8, and there is a promotion in the pressure chamber to cooperate with the piston 6 to...

Abstract

A pneuamtic controller for IC engine (diesel engine or gasoline engine) to drive air compressor is composed of a cylinder body, piston, piston rod and cylinder cover. A hole for linking the pull string of throttle if IC engine is made on the external end of piston. An adapter to air tank as air source is made on the external surface of cylinder. When the compressed air is normally consumed, the pressure in air tank is normal. If the air consumption is stopped, the pressure in air tank is increased to push piston to move. The piston rod moves inward to pull the pull string of throttle, so decelerating the IC engine and in turn the air compressor to autoamtically regulate the output of air compressor.

Description

technical field [0001] The invention relates to a controller, which is mainly used in an air compressor driven by an internal combustion engine. The air pressure of the air storage tank of the air compressor is used to change the throttle cable of the internal combustion engine to automatically adjust the operation status of the internal combustion engine. Background technique [0002] The air compressor is generally driven by a motor, but in the wild, especially in remote mountainous areas, an air compressor is used to open rocks, etc., and only an internal combustion engine (such as a diesel engine) is used to drive it. The use of compressed air is often intermittent. When it is not used intermittently, the internal combustion engine cannot be turned off and completely shut down, otherwise it will be troublesome to start. If you keep inflating when you stop using the gas, it will cause dangers such as frying the tank. Therefore, when the air compre...
