摘要： Arrangements of a flow path to achieve a series circuit, a regeneration circuit and a float/passive regeneration circuit. For example, a valve body having a spool bore, a valve inlet, a plurality of cavities opening into the spool bore and a spool disposed in the spool bore. A first cavity fluidly connected to a tank passage, a second cavity fluidly connected to a first work port, a third cavity fluidly connected to an inlet of another valve, a fourth cavity fluidly connected to a second work port, a fifth cavity fluidly connected to the valve inlet, a sixth cavity fluidly connected to the first work port, a seventh cavity, an eighth cavity fluidly connected to the valve inlet, a ninth cavity fluidly connected to the inlet of the other valve and a tenth cavity fluidly connected to the valve inlet.

摘要： A hydraulic valve assembly includes a valve body having a spool bore, a valve inlet, and a plurality of cavities opening into the spool bore; and a spool disposed in the spool bore. A first cavity fluidly connected to a tank passage; a second cavity adjacent the first cavity and fluidly connected to a first work port; a third cavity adjacent the second cavity and fluidly connected to an inlet of a another valve; a fourth cavity adjacent the third cavity and fluidly connected to a second work port; a fifth cavity adjacent the fourth cavity and fluidly connected to the valve inlet; a sixth cavity adjacent the fifth cavity and fluidly connected to the first work port; a seventh cavity adjacent the sixth cavity; an eighth cavity adjacent the seventh cavity and fluidly connected to the valve inlet; a ninth cavity adjacent the eighth cavity and fluidly connected to the inlet of the other valve; and a tenth cavity adjacent the ninth cavity and fluidly connected to the valve inlet.
