Abstract

[PROBLEMS] The provision of a reciprocating valve in which a tiny bit of seal wear on a valve body is measured accurately with interlock of a gauge pin with reciprocating movement of a valve stem so as to reflect with high-precision the reciprocating movement of the valve stem to the gauge pin, even with simple construction. [MEANS FOR SOLVING PROBLEMS] The reciprocating valve includes a valve stem (2) connected with a piston (1), a valve body (3) mounted to the end of the stem, a yoke (41) coupled to a valve housing (4) and made therein with a guide hole (5) extending through across the yoke, and a gauge pin (6) allowed to reciprocate in response to reciprocating movement of the stem. The gauge pin fits loosely into the guide hole with the tip end (60) thereof extending out of the yoke in a way variation in amount of extension of the gauge pin out of the yoke can be identified. Moreover, the gauge pin (61) is urged with a spring (62) to come into resilient abutment at its pedestal end against the piston.
