Claims

[Scope of Claim for Utility Model Registration] (1) A pair of left and right liquid chambers are defined in the hollow hole by a spool that is reciprocatably housed in the hollow hole of the valve body, and hydraulic fluid is introduced into these liquid chambers from the inflow port. At the same time, in the diversion valve configured to divert this working fluid to a discharge port communicating with each fluid chamber,
A flow dividing valve characterized in that the inflow port and one liquid chamber communicate with each other via a variable orifice, and the inflow port and the other liquid chamber communicate with each other via a fixed orifice. (2) A spool is accommodated in the hollow hole of the valve body, and the spool forms a pair of left and right liquid chambers, and the liquid that flows into the hollow hole from the inlet port is introduced into each liquid chamber via a branch channel. On the other hand, a flow divider valve is characterized in that the liquid introduced into each of these liquid chambers is distributed to each discharge port of the flow divider valve, and a variable orifice is disposed in the flow path of the flow divider.
