This distributing valve has: a top block (1) provided with an injection opening (7); a base block (30); and at least one intermediate block (60) sandwiched between the top block (1) and the base block (30). Each block incorporates a pair of valve spools (15, 45, 75), but meanwhile has a plurality of discharge openings (19, 49, 79). When the top block (1), base block (30), and intermediate block (60) are superposed, a complex pathway is formed within the blocks from the injection opening (7) to each discharge opening (19, 49, 79), and while the complex pathway causes the sequential reciprocating motion of each valve spool by means of a lubricant injected from the injection opening (7), meanwhile the lubricant is sequentially discharged from each discharge opening (19, 49, 79) using the reciprocating motion of each valve spool. |
