| description | The invention provides a rotary cushion valve for improving the stability of a rotary system and a working method of the rotary cushion valve. The rotary cushion valve relates to the technical field of hydraulic pressure of engineering machinery and comprises a reversing valve, a shuttle valve, a first one-way valve, a second one-way valve, a third one-way valve, a first overflow valve and a second overflow valve, a reversing valve is arranged in parallel between an oil inlet path where the oil inlet is located and an oil outlet path where the oil discharge port is located, the reversing valve comprises a throttling loop and a normally closed loop, a first damping hole is formed in the throttling loop, and a pilot port of the pilot loop is communicated with an outlet of the shuttle valve. And a second damping hole is formed between the inlet of the first overflow valve and the oil discharge port in series. By improving the rotary cushion valve, pressure impact and pressure fluctuation can be reduced during ro |
