Реферат: The hydraulic directional control valve is used in a control unit for a single or double acting working cylinder. It is esp. used in load sensing (LS) technology. The longitudinal bore (12) contains middle and outer chambers (33,31) and a further chamber (32) is formed between them as a ring shaped widening of the bore. USE/ADVANTAGE - Valve for use in the drive system of an agricultural vehicle in which the extra chamber enables the valve housing to be adapted for left or right hand use, so saving casting costs.
