ABSTRACT:
An aspiration sprayer comprises a disc valve for controlling the degree of aspiration over a very wide range by means of a plurality of passages of different sizes formed in the disc valve and selectively introduced into the flow path of the liquid to be aspirated, the disc valve rotating with a knob and being spring-urged into leakproof relationship with that flow path, the carrier liquid with aspiration material entrained therein emerging from the sprayer in a strong jet-like stream the nature and direction of which can be modified by a deflector mounted on the device so as to be slidable between operative positions. The knob and the disc valve may be readily assembled and disassembled and the operative passages of the valve are accessible for cleaning without requiring disassembly of the device. The passages in the disc valve may comprise a plurality of radially enlarged vortex areas interconnected by spaces of lesser width.
