Beschreibung
Zusammenfassung:	An object of the present invention is to solve such problems associated with installing of a spool-type regenerative valve, in that an overall installation space of a hydraulic valve increases and processing that requires accuracy becomes complex. A regenerative circuit includes: a regenerative oil path provided in a valve body of a direction switching valve so as to connect a supply oil path connected to one side of a hydraulic actuator and a discharge oil path connected to the other side; and a regenerative valve which is a poppet-type flow regulating valve that is screwed into and attached to the valve body so as to control the flow of oil in the regenerative oil path according to an operation state of the direction switching valve.
