ABSTRACT:
A spray head for a fluid dispenser comprises a connecting bore for sealingly receiving a delivery tube stub of an aerosol valve; a spray orifice; a main chamber connecting the connecting bore and the orifice; a piston member disposed in the main chamber and presenting a needle member cooperating with the orifice; and a spring urging the piston member to the orifice. The orifice is sealed by the end of the needle member in an inoperative position, and the piston member is arranged to move against the force exerted by the spring under the influence of an elevated pressure prevailing in the main chamber, whereby the orifice is cleared by the needle member. To provide for an improved spray, the rear part of the piston member, together with a sealing member placed at an axial distance from the rear part of the piston member, defines a closed space through which a one-way valve is in communication with the main chamber for the injection of air from the closed space into the product stream to be sprayed through the spray orifice when the piston member moves in the direction of the sealing member.
