Speed ​​regulating valve accumulator

What is a controllable accumulator?

The controllable accumulator comprises a main piston hydraulic accumulator, a two-position hydraulic valve (YV1), a three-position proportional valve (YV2), a high-speed on–off hydraulic valve (YV3), a high-speed on–off pneumatic valve (YV4) and a gas regulator.

Does a higher speed accumulator valve make a better shift?

So, a higher speed will result in greater back pressure to the accumulator piston, which will result in a firmer and quicker 1-2 shift. This accumulator valve has various size ratios from OE to provide different shift feels for various vehicle and engine combinations.

How does a speed-regulation valve work?

Flow Rate Analysis According to the working principle of the speed-regulation valve, the hydraulic oil flows from the inlet into the valve chamber through the throttle valve port and out through the oil outlet through the throttle valve port of the pressure compensator without considering leakage.

How does accumulator valve work?

In this instance, the accumulator piston is absorbing 2nd apply pressure by working against a spring and throttle-sensitive fluid force, which is provided by the accumulator valve as it regulates D4 pressure into the 1-2 accumulator circuit.

What is the working principle of speed regulating valve?

Flow chart of working principle of speed-regulating valve. The pressure compensator is sensitive to the change in the pressure difference. The change in the pressure difference causes the displacement of the pressure compensator and then causes the changes in the throttling area to achieve the purpose of flow-rate regulation.
