As a core component of hydraulic and pneumatic systems, the on-off valve is generally controlled by an electromagnet to open and close the valve core for a long time. So, in some specific situations, a fluid opening and closing valve with continuous cycles, fast and reliable opening and closing, and good sealing is the key to achieving high-frequency motion of the actuator. The existing on-off valves are mostly linear motion type, working in high-pressure and high flow environments, with high stress on the valve core, and ordinary electromechanical converters such as electromagnets are difficult to meet the requirements for use. The cost of long-life solenoid valves is very high, which increases the cost and reliability factors. Moreover, most solenoid driven valves are reset by springs, and the reset ability of springs also limits the development of high-pressure, high-frequency, and high flow valves.

summary of the invention

In order to overcome the shortcomings of the existing technology mentioned above, the purpose of the present invention is to provide a rotary fluid high-frequency multi-path opening and closing valve, which achieves high-speed periodic opening and closing by driving the valve core to rotate through the rotation of a motor.
