<p>PROBLEM TO BE SOLVED: To provide an improved pre-detent tactile feedback assembly for fluid control valve less in required number of parts and easy in assembly and disassembly. SOLUTION: A pre-detent tactile feedback assembly 50 comprises an elastic member 51 seated in an annular groove 52 formed inside a hole 31 of a plunger valve assembly. As this elastic member, a garter spring may be used. When a part of the plunger touches the elastic member to energize the elastic member outward into the annular groove. An additional force required for energizing the elastic member into the annular groove provides a tactile force to a control lever. The annular groove may be positioned in the hole 31 so that the tactile force can be detected immediately before the detent assembly operated in association with the tactile force is operated.</p> |
