Description

Technical field:

[0001] The present invention relates to a speed control regulator for a pressure cylinder. Background technique:

[0002] The speed control loop of the pressure cylinder includes medium, medium control loop bypass throttling control loop, and series-parallel synchronous control loop. These loops need to be composed of multiple components that are relatively complex, with high cost and poor control accuracy. Invention content:

[0003] The object of the present invention is to provide a speed control device for a working cylinder with simple structure, few required components, low cost and high control precision.

[0004] The present invention is achieved like this:

[0005] In the speed control device of the working cylinder of the present invention, the inlet and outlet medium circuits of the working cylinder are connected with a two-position or three-position four-way reversing valve, and there are differential flow adjustable shuttle valves on the med...
