Abstract:
A fluid control valve includes: a sleeve in a bottomed cylindrical shape, including an inlet, communication ports, an inner peripheral surface, and an inflow annular groove recessed from the inner peripheral surface in a region facing the inlet; a spool slidably disposed on the inner peripheral surface in the sleeve to open and close the communication ports; a C-shaped leaf spring formed by bending a leaf spring into an annular shape with two ends facing each other to form a notch and disposed in the inflow annular groove capable of being contracted in diameter to open and close the inlet; and a restricting part provided on the sleeve for restricting diameter contraction of the C-shaped leaf spring beyond a predetermined inner diameter and for restricting a position of the notch in a region away from the inlet.
