<p>Apparatus for generating a high pressure water jet is disclosed which comprises a tank (12) which forms a reservoir (14) containing a liquid, such as water. An elongated conduit (18) has one end (20) fluidly connected to the reservoir while a nozzle (26) is connected to the other end (28) of the conduit. This nozzle, furthermore, has an out opening (30) with a cross-sectional area less than the cross-sectional area of the conduit. A valve (22) is connected in series between the conduit and the reservoir, and this valve is movable between an open and a closed position. The reservoir is pressurized to a pressure in the range of 2-20 bar (30-300 psi) so that, once the valve is opened, water flows through the conduit and out through the nozzle as a high pressure and high speed water jet. This water jet can be used, inter alia, to clean industrial parts, such as engine blocks during manufacturing. <IMAGE></p> |
