A recovery check valve 26 and a piston valve 27 are axially slidably disposed within a spool 2 in coaxial relation. An axial fluid passage 32 is formed within a cylindrical portion 27a of the piston valve 27, and a seat portion 33 for the recovery check valve is formed at an open end of the cylindrical portion 27a. The cylindrical portion 37a of the piston valve is formed with a hole 36 through which a hydraulic fluid in the fluid chamber 32 is introduced to a bridge passage 21 when the spool 2 is operated so as to introduce a hydraulic fluid from a hydraulic pump to the bottom side of a hydraulic cylinder. Fluid passages 40, 31 are formed within the spool so that a hydraulic fluid in the bridge passage 21 is introduced to the closed end of the piston valve through the fluid passages when the spool is operated in the opposite direction. With such a structure, the size of the valve apparatus can be set to the same size as the directional control valve not provided with the recovery check valve.

[ What is claimed is:] [1.]1. A directional control valve apparatus comprising a casing (1), a spool (2) axially slidably disposed in a spool bore (1a) of the casing (1), and a load check valve (3), the spool bore of said casing being formed with two reservoir ports (4, 5), two actuator ports (6, 7)

[ What is claimed is:] [1.]1. A directional control valve apparatus comprising a casing (1), a spool (2) axially slidably disposed in a spool bore (1a) of the casing (1), and a load check valve (3), the spool bore of said casing being formed with two reservoir ports (4, 5), two actuator ports (6, 7), two communicating ports (11, 12) and three center bypass ports (8, 9, 10) in the order named from both outer axial ends toward the center, said casing being formed with a bridge passage (21) connected to a hydraulic pump (22) through said load check valve and interconnecting said two communicating ports, a center bypass passage (23) for connecting said hydraulic pump to the middle port (10) of said three center bypass ports, and a center bypass passage (24) for interconnecting the other two center bypass ports (8, 9) and connecting these two center bypass ports to a reservoir (25), said spool having a recovery input passage (29) and a recovery output passage (30) both formed therein, said spool including a recovery check valve (26) axially slidably disposed within said spool between said recovery input passage and said recovery output passage, said valve apparatus operating such that when said spool is operated in one direction, said recovery check valve is opened to communicate said recovery input passage and said recovery output passage with each other for recovering a hydraulic fluid returned through the meter-out-side port (6) of said two actuator ports to said bridge passage (21) via said recovery input passage, said recovery check valve, said recovery output passage and the communicating port (11) on the same side as said meter-out-side actuator port (6),wherein piston valve means (27, 31, 40) is provided within said spool (2) for closing said recovery output passage (30) when said spool is operated in a direction opposite to said one direction.
