摘要

A quick connector (1) with built-in flow control valve, particularly for connecting flexible hoses to gas distribution lines. The connector comprises a connector body (2) inside which there is a flow control chamber (3) that is connected to at least one inlet (4) and one outlet (5). The flow control chamber (3) accommodates a flow control element (6) that can rotate with respect to the connector body in order to pass from an open position to a closed position. An engagement seat (10) is formed at the inlet or outlet and is suitable to receive an end sleeve (11) of a hose (12) to be connected to the connector body. The connector is provided with an actuation knob (13) that can be actuated in order to produce the transfer of the flow control element (6) from the closed position to the open position and to lock the end sleeve (11) in the engagement seat (10) or to transfer the flow control element (6) from the open position to the closed position and to release the end sleeve (11) from the engagement seat (10). <IMAGE>
