Abstract
A multifunctional fluid shut-off device including an upstream shut-off element, a flow-rate limiter, and a downstream functional element. The upstream shut-off element presents a body in which at least one valve is disposed, and a downstream end includes an exit port to which the downstream functional element is operatively connected. At least one of the upstream shut-off element and the downstream functional element includes a retention mechanism for the flow-rate limiter. A unit including the downstream functional element is directly connected to the upstream shut-off element containing in its interior the flow-rate limiter.
Claims28
A multifunctional fluid shut-off device comprising:
- an upstream shut-off element including
- a body in which at least one valve is disposed, and
- a downstream end having an exit port;
- a flow-rate limiter;
- a delivery nozzle that is operatively connected to the exit port of the upstream shut-off element;
- and
- a connection member including gripping elements and respective gripping counter-elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port via which the delivery nozzle is connected to the exit port of the upstream shut-off element such that the delivery nozzle is continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom;
- wherein at least one of the upstream shut-off element and the delivery nozzle includes retention means for the flow-rate limiter, and
- wherein the delivery nozzle is directly connected to the upstream shut-off element and contains in an interior thereof the flow-rate limiter.
A delivery nozzle configured to operatively connect to an exit port of an upstream shut-off element, comprising:
- direct retention means to retain a flow-rate limiter such that the flow-rate limiter lies at least partially within the delivery nozzle;
- and
- gripping counter-elements that engage corresponding gripping elements of the upstream shut-off element, each of said gripping elements and gripping counter-elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port, such that the delivery nozzle is secured to an exit port of the upstream shut-off element, the delivery nozzle being continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom.
An upstream shut-off element comprising:
- a body on which at least one valve is disposed, the body including a downstream end having an exit port that is operatively connected to a delivery nozzle;
- gripping elements that connect the delivery nozzle to the exit port of the upstream shut-off element, said gripping elements arranged tangentially to said upstream shut off element and said delivery nozzle and insertable through said exit port, the delivery nozzle being continuously rotatable with respect to the upstream shut-off element without disconnecting therefrom;
- and
- direct retention means to retain a flow-rate limiter such that the flow-rate limiter lies inside the delivery nozzle directly connected to the upstream shut-off element.
