Abstract
A pressure responsive sequence device wherein in order to carry out the pressure responsive sequencing operation in both the meter-in and meter-out flow control modes, between a supply line and a discharge line of a primary actuator is inserted a switching valve which automatically switches, in response to the pressure difference between the supply and discharge lines, to communicate either of them having a lower pressure than the other with a tank through a low pressure relief valve; and a sequencing valve is inserted in a supply line which communicates a pump in a hydraulic power source with a secondary actuator.
