Problems solved by technology
[0002] Injection volume and response time are two important parameters to measure the pros and cons of gas injection valves. Due to the low density of gas, the diameter of the valve required for large injection flow is also large, but the large gas working pressure acts on On the valve, it will hinder the opening and closing movement of the valve and restrict the response time
Therefore, the high-speed electromagnetic gas injection valve driven by electromagnetic can generally only adapt to the small flow requirements and low gas pressure conditions, and cannot meet the high-speed quantitative injection under the requirements of large flow and high pressure.

The invention discloses a pressure-balanced type gas jet digital valve which comprises a valve body. An air inlet passage and an air outlet port are arranged on the valve body, and a valve core is mounted inside the valve body in a sliding mode. A moving armature is arranged at one end of the valve core, a static armature and an electromagnetic coil are arranged on the valve body, the static armature, the electromagnetic coil and the moving armature form an electromagnet, and the moving armature is pulled by the electromagnet in the direction same with the sliding direction of the valve core. A reset spring is arranged between the valve body and the moving armature, a first valve and a second valve are arranged on the valve core in the sliding direction of the valve core, and the air inlet passage comprises a first air inlet port and a second air inlet port. When the digital valve is closed, the first valve and the second valve are located between the first air inlet port and the second air inlet port, and the air outlet port is located between the first valve and the second valve. By means of the pressure-balanced type gas jet digital valve, the purpose of high-flow and rapid responsive jetting is achieved under a high-pressure gas condition.
Description
technical field [0001] The invention relates to the technical field of gas engines, in particular to a pressure-balanced gas injection digital valve. Background technique [0002] Injection volume and response time are two important parameters to measure the pros and cons of gas injection valves. Due to the low density of gas, the diameter of the valve required for large injection flow is also large, but the large gas working pressure acts on On the valve, it will hinder the opening and closing movement of the valve and restrict the response time. Therefore, high-speed electromagnetic gas injection valves driven by electromagnetics can generally only adapt to smaller flow requirements and lower gas pressure conditions, and cannot meet high-speed quantitative injection under larger flow and higher pressure requirements. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a pressure-balanced gas injecti...
