ABSTRACT:
A valve actuator, usable in pump-type and aerosol fluid product dispensers, includes a one-piece part mounted on the plunger or valve stem of the dispenser for axial reciprocating movement therewith and for rotation relative thereto. The upper end of the plunger or stem has a cylindrical segment covering a cavity surrounding the discharge orifice and a tangentially extending groove so as to form, in a first relative position of the actuator, a swirl chamber and a fluid passage which is open beyond the periphery of the segment so as to establish communication between the outlet of the plunger and the orifice via the fluid passage to thereby effect a fluid spray from the swirl chamber upon plunger reciprocation. In a second relative position of the actuator, the segment uncovers the groove and cavity so as to establish direct communication between the plunger outlet and the discharge orifice so that the fluid is discharged as a solid fluid through the orifice upon plunger reciprocation.
