and to a crimping of the ring on the trigger and, on the other side, angularly, by local depression of the crimping of the ring in at least

a trigger recess.

According to yet another feature, the

lifting stroke of the collar at the moment of the trigger maneuver for opening is defined by

a stop. This preferably consists of an annular space inside the cap. j

j It should be noted that in relation to the thrust

? born in rotation from the steering wheel is reduced in a way

that the breechblock remains angularly immobile, while at the moment of the trigger maneuver, which implies a tilting, the tendency of the breechblock to be moved laterally is also reduced and in any case limited to a lateral travel of negligible value.

For this purpose, according to another feature of the invention, the upper surface of the organ-,

<?>

F o - ?<?' >

The steering wheel is positioned close to the body's supporting surface for the collar. This allows for a particularly compact construction with a saving in material.

Preferably, the handwheel acts in contact with the upper surface of the breechblock by means of a harder head than this, for example in the form of a sphere which is allowed to excavate a small depression in the upper surface of the breechblock during operation. In this case, to minimize the drag effect of the breechblock when the trigger is reversed, it is planned to place the center of the sphere

or in a plane coplanar with the supporting surface u -O ooc of the body for the collar when the grill O bed is halfway between the open position and 2Q. the closed position.

In one embodiment, the elastic means comprises a helical spring which extends between the ring nut and the cap, while the handwheel comprises, on one side, a central threaded rod by which it is screwed into the ring nut and which cooperates in pushing on the shutter organ and on the other side, a peripheral gripping crown which surrounds a part of the

the trigger has two concentric and spaced casings: an internal casing which is

? I

fixed to the ring nut and an external casing that surrounds the cap and is itself surrounded by the peripheral grip ring of the steering wheel.

_ In a preferred embodiment the supporting surface of the body on which it rests_

the collar of the bezel is defined by a stud

<" >' <^ >-- - the ring of the body on which the cap is screwed to fix it to the body.

Preferably? The shutter organ cooperates

I

|with the seat of the tap due to the deformation of a toric joint made of elastomer material or _o0) which is carried by the shutter organ and is applied or occluded against the seat, which is made of rigid material < i Ci<~ >Q. |and advantageously has a conical shape, the said seat having one or more local depressions which allow a small flow of flame to pass when

{where the joint touches the seat but are plugged to allow for complete closure when the joint is compressed against the seat.

The tap according to the invention also has the notable property of being usable with both a double steering wheel control and a single steering wheel trigger, i.e. in the absence of a trigger.

In this case, for such a use, the steering wheel is directly screwed into an organ generally having the shape of an inverted annular gutter and replacing the cap and the ring alone, the elastic means being eliminated.

Whether the cocking...is double or simple, the steering wheel cooperates advantageously in pushing the shutter organ by means of a sphere, while...

This organ is called open by a spring that rests on the body and is placed on the opposite side of the speaker...

_ However, in a simplified version, the cu

o (The selling price is reduced, the assembly of the shutter organ directly in a solid manner to the steering wheel is foreseen and, in this case, the shutter organ is without a return spring.

Another object of the present invention is such a single-action valve, in which the shutter member is integral with the steering wheel and is allowed to rub directly in rotation on the seat of the valve. Such operating conditions may give rise to fears of premature wear, but experience has shown that, surprisingly, the seal of the valve is very good.

__ Preferably, in this simplified version, the valve has a radial disc that facilitates the operation and indicates, at all times, the position in which the tap is located.

Some embodiments of the invention are described below, by way of example.

The control unit 15 (figures 1 to 4) includes a control handwheel 18. The handwheel 18 has a central threaded rod 19 and a peripheral grip ring 20. The handwheel 18 pushes the shutter organ 14 for closing, that is, by means of its central rod 19 or by means of a ball 21. The shutter organ 14 is activated by a spring 22 which rests on the body placed on the opposite side of the handwheel 18.

_ The control unit 15 also includes an operating trigger 23. This is integral with a ring nut 24 in which the steering wheel 18 is mounted by means of its central threaded rod 19. _ or t-< oc . . Q.

Means are provided to prevent the trigger 23 from rotating in either direction around the steering wheel axis. 1.8. For this purpose, the grill 23, generally in the shape of an inverted gutter (figures 1 and 1A), is permitted to cover a cover 41 located on the handle. P.

The ring 24. (figure 1) is made integral with the trigger 23 on one side axially thanks to a crimping_43_of the ring 24 on the trigger 23 and

on the other side, angularly, by local recessing of the crimp 43 of the ring 24 in one or more recesses 45 of the trigger 23. - The ring 24 has a collar 25 which rests on an annular bearing surface 26 of the body 10 at the entrance 27 of the hole 12 under the action

_o o Furthermore, such a faucet has the property of allowing the use of the same body as has just been described, in a standard way, either with the double steering wheel control 18 and trigger 23 shown on figures 1 to 4, or with a simple steering wheel control 18, i.e. without trigger 23.
