Filling head for a device for dispensing a fluid product having a valve

A filling head for a device for dispensing a fluid product, comprising a valve mounted on a reservoir by means of a securing element, said valve comprising a valve shutter provided with an axial outlet orifice sliding in a valve body, said filling head comprising:

• a body comprising a receiving space,
• a control member mounted so as to slide axially in said body between a rest position and a filling position, said control member comprising a filling channel through which, in the filling position, the pressurized fluid product is fed to said valve in order to fill said reservoir, said filling channel comprising an outlet orifice opening into said receiving space,
• an upper plate through which said control member passes and which is secured to said body,
• a supporting ring secured to said control member and cooperating with a first spring disposed between said supporting ring and said body,
• a receiving plate secured to said body and comprising a housing for receiving said valve such that, in the filling position, the axial outlet orifice of said valve shutter opens into said receiving space,
• in which, in the filling position, said receiving space has a seal comprising a first gasket between said control member and said body, a second gasket between said body and said receiving plate, and a third gasket between said receiving plate and said valve shutter, said third gasket cooperating with an outer side wall of said valve shutter, and
• valve ejection means for ejecting said valve from said housing after filling,
• characterized in that said ejection means comprise:
• an ejector cylinder disposed in said body,
• at least one ejector which is axially displaceably disposed in said body between an ejection position and a filling position, each ejector being disposed between said ejector cylinder and said support plate, each ejector comprising an enlarged head and a stem extending axially downwards from said enlarged head, said stem passing through said body and said receiving plate in order to project into said housing in the ejection position, and
• a second spring disposed between said ejector sleeve and said upper plate and urging said at least one ejector towards its ejection position.
