DEVICE FOR SUPPLYING A LIQUID TO AN APPARATUS FOR JOINING TEXTILE THREADS OR YARNS BY MEANS OF COMPRESSED GAS AND LIQUID AND AN APPARATUS FOR JOINING TEXTILE THREADS OR YARNS BY MEANS OF COMPRESSED GAS AND LIQUID COMPRISING SUCH A DEVICE

摘要

A device (10) for supplying a liquid to an apparatus (11) for joining textile threads or yarns by means of compressed gas and liquid of the type comprising a mingling chamber (14), inside which the ends of a textile thread or yarn to be joined can be inserted and at which a delivering duct (33) for delivering compressed gas and liquid comes out, and a compressed gas introducing valve (20) that is provided with an inlet and with at least one outlet (23) of said compressed gas, such a device being characterised in that it comprises a cylindrical body (26) internally hollow and which can be associated with the joining apparatus (11), a liquid supplying chamber (27) which is defined in the cylindrical body (26) and which is provided with an inlet (28) that can be associated with a liquid source, a collecting and mixing chamber (30) which is defined in the cylindrical body (26) and which is provided with an inlet mouth (31) of said compressed gas and with an outlet mouth (32) of compressed gas and liquid wherein the latter outlet mouth (32) can be associated with the delivering duct (33) for delivering compressed gas and liquid to the mingling chamber (14), a chamber (34) for supplying compressed gas which is defined in the cylindrical body (26) and which is provided with an inlet opening (35) of compressed gas which can be associated with the outlet (23) of the compressed gas introducing valve (20) and with an outlet opening (36) of the compressed gas supplied into it which is in fluid communication with the inlet mouth (31) of the collecting and mixing chamber (30) , and a plunger (38) which is provided with a cavity (39) open towards the inside of the cylindrical body (26) for transferring a dose of liquid from the liquid supplying chamber (27) to the collecting and mixing chamber (30) and which is sealingly housed in the cylindrical body (26) in a manner axially mobile between a rest position and a working position of the device (10) itself upon control by action of the thrust exerted onto it by the compressed gas supplied into the compressed gas supplying chamber (34) from the compressed gas introducing valve (20), when the latter switches in order to supply the compressed gas in exit from the outlet (23).
