Abstract

In a flow control apparatus, a fluid pressure is introduced from downstream of a metering orifice to a rear room of a spool while a relief valve in the spool is assembled in advance. A front section of a relief valve sub-assembly is press fitted to a hole provided on the spool and is opening to rear room of the spool so that a receiving room of a valve body in a relief valve casing communicates to a bypass path. A communicating path provided in a rod communicates to the rear room of the spool through outside of the relief valve sub-assembly. The relief valve casing is received in a receiving hole provided in the spool and a cylindrical room between the relief valve casing and the receiving room is used as a part of a communicating path.
