A dispenser for discharging media to be used in conjunction with a pressure chamber, said dispenser comprising:

• a medium outlet;
• an outlet channel having at least two spray nozzles spaced in a medium flow direction, said outlet channel leading into said medium outlet, said outlet channel defining said medium flow in operation, said outlet channel, at a distance from said medium outlet, having a channel portion provided to connect to said pressure chamber and operable for producing a delivery pressure in a range of increasing medium pressures, from a relatively lower medium pressure to a relatively higher medium pressure, said outlet channel having adjustable passage cross-sections;
• and,
• control means for increasing said passage cross-sections to a relatively larger cross-section at said relatively lower medium pressure and to constrict said passage cross-sections smaller than said relatively larger cross-section at said relatively higher medium pressure.

A dispenser for discharging media to be used in conjunction with a pressure chamber, comprising:

• a medium outlet defined by a first duct end of a linear end duct including a second duct end remote from said first duct end;
• an outlet channel leading into said end duct, said outlet channel defining a medium flow with a flow direction toward said medium outlet during dispensing operation, said outlet channel having a channel portion directly connecting to said end duct, said channel portion including channel boundaries including an inner circumferential surface and a recessed end face directly connecting to said inner circumferential surface, said channel portion connecting to said pressure chamber and being operable for producing a delivery pressure in an increasing range between a relatively lower medium pressure and a relatively higher medium pressure, said channel portion determining passage cross-sections;
• a core body operatively bounding said channel portion opposite to said channel boundaries, said core body being operationally unidirectionally movable from an initial control position to a control end position in a first control direction defined by a first core motion for varying the medium flow and for modifying the medium flow together with the increasing medium pressure to thereby vary said passage cross-sections,
• wherein said core body has outer faces including an outer circumferential face and a free end face, said outer faces directly facing said channel boundaries, in said initial control position of said core body and of said dispenser, said outer faces and said channel boundaries commonly bounding an angular passage gap for passing the medium, said angular passage gap including an axial gap lea defining first flow cross-sections, said first flow cross-sections being constant during said first core motion and said dispensing operation, said passage grap including a transverse gap leg directly connecting to said axial gap leg at an angle and defining second flow cross-sections, said second flow cross-sections varying substantially continuously during said first core motion and said dispensing operation, said transverse gap lea being oriented transverse to said first control direction and being located downstream of said axial gap leg, said transverse gap leg being bounded by a groove.

A dispenser for discharging media to be used in conjunction with a pressure chamber, comprising:

• a medium outlet defined by a first duct end of a linear end duct including a second duct end remote from said first duct end;
• an outlet channel leading into said end duct, said outlet channel defining a medium flow with a flow direction toward said medium outlet during dispensing operation, said outlet channel having a channel portion at a distance upstream from said medium outlet, said channel portion connecting to said pressure chamber and being operable for producing a delivery pressure in an increasing range from a relatively lower medium pressure to a relatively higher medium pressure, said outlet channel determining passage cross-sections;
• a core body operatively associated with said outlet channel and movable during said dispensing operation in a first control direction from an initial control position to a control end position by a first core motion for varying the medium flow, said core body being movable in said first core motion for modifying the medium flow together with the increasing delivery pressure to thereby vary at least one of said passage cross-sections;
• said core body having a circumferential face and an end face connecting to said circumferential face;
• and,
• said channel portion including at least one angular channel groove, said at least one angular channel groove including an axial groove leg located at said circumferential face and a transverse groove leg downstream angularly directly connecting to said axial groove leg, said transverse groove leg being oriented transverse to said first control direction and located at said end face.

• a medium outlet defined by a first duct end of a linear end duct including a second duct end remote from said first duct end;
• an outlet channel leading into said end duct, said outlet channel defining a medium flow with a flow direction toward said medium outlet during dispensing operation, said outlet channel having a channel portion at a distance upstream from said medium outlet, said channel portion connecting to said pressure chamber and being operable for producing a delivery pressure in an increasing range from a relatively lower medium pressure to a relatively higher medium pressure, said outlet channel determining passage cross-sections;
• a core body operatively bounding said channel portion, said core body being operationally unidirectionally movable from an initial control position to a control end position in a first control direction defined by a first core motion for varying the medium flow, said core body being movable in said first core motion for modifying the medium flow together with the increasing delivery pressure to vary at least one of said passage cross-sections;
• opposing end faces including a most downstream end face on said core body being included, said end face being bounded by a circumferential face defining an imaginary circumferential envelope, said opposing end faces further including a counter face directly opposing said end face, said end face approaching said counter face during said first core motion;
• and,
• flow control means recessed in one of said end faces, said flow control means including at least one depression located within said circumferential envelope, said flow control means imparting a turbulence to the medium flow.

A dispenser for discharging media, comprising:

• a squeeze bottle bounding said pressure chamber;
• a medium outlet;
• an outlet channel leading into said medium outlet said outlet channel defining a medium flow during dispensing operation, said outlet channel having a channel portion at a distance from said medium outlet, connected to said pressure chamber and operable for producing a delivery pressure in an increasing range of pressure, said outlet channel determining passage cross-sections;
• a holding spring for said at least one core body, said holding spring engaging inside said pressure chamber and said squeeze bottle bounding said pressure chamber;
• at least one core body operatively associated with said outlet channel, said at least one core body being operationally movable for varying the medium flow, said at least one core body being movable in a first core motion for modifying the medium flow together with the increasing delivery pressure to vary at least one of said passage cross-sections;
• and,
• means for moving said at least one core body in a second core motion substantially distinct from said first core motion.
