ABSTRACT:
Pump apparatus for delivering water based formulations as an aerosol spray provides for quantities of liquid and air to be pressurized in separate chambers by pump action. Liquid is dispensed through an orifice via a dispensing channel which in one embodiment is purged during a terminal part of the actuating stroke by the release of air through the dispensing channel. In the second embodiment air and liquid are mixed during the actuating stroke so as to be dispensed together and during a return stroke air is sucked through the dispensing channel to remove residual liquid. The air purging action prevents the build-up of deposits in the dispensing channel and orifice.
