1. A water saving valve (1) which is used by being attached to a connection between an outlet side flow path (22) and an auxiliary flow path (23) at an outlet side of a flow rate control opening / closing plug (21), In a water-saving valve for a flow control on-off cock, the opening-side operation of the on-off cock (21) decreases the outlet-side flow of the water-saving valve as the flow rate in the outlet-side flow path (22) increases. A fluid inlet opening (7) provided on one end side, and a first fluid outlet opening (8A) provided on an end wall (9) on the other end side in the axial direction and facing the fluid inlet opening (7). A plurality of second fluid outlet openings (8B) provided on the peripheral wall (10) at the other end in the axial direction, and an inner diameter communicating with the fluid inlet opening (7).
r1 and a first inner diameter portion (6A) and an inner diameter r2 (r2 <r1) communicating with the first and second fluid outlet openings (8A) and (8B).
A second inner diameter portion (6B) and the first inner diameter portion (6A)
(2) provided with a conical valve seat surface portion (6C) connecting between the second inner diameter portion (6B) and the first inner diameter portion (6A) of the casing (2). Outer diameter R (r1> R stored movably
> R2) and a stopper member attached to the casing (2) on the side of the fluid inlet opening (7) to limit the axial movement of the spherical valve element (3). 5), and between the spherical valve element (3) and the inner surface of the end wall (9) of the casing (2) to urge the spherical valve element (3) toward the stopper member (5). A water-saving valve for a flow control on-off cock, characterized by comprising a coil spring member (11).
