Research for Guide Groove Configuration of Rotary Valve

Abstract:

Rotary valve is a device to achieve fast commutation hydraulic transmission . Rotary valve is driven by a hydraulic motor drive and can achieve rapid conversion of the hydraulic circuit . Rotary valve spool by a rotating shaft , housing , shafts and bearings and other components. Guide grooves machined on the spool shaft is evenly distributed for hydraulic cylinder into the oil and return oil conversion. The coordinate gap between the spool shaft and valve chamber bore Because will affect the leakage in the leak. How to improve the guide groove structure We can put the guide groove by high and low partition instead of overlapping arrangement. Reducing leakage within the valve chamber and Meet with the requirements of the spool shaft and valve chamber bore.
